And thus, there would be no chance of flashing the firmware to revive/unbrick the device. For example, for Nexus 6P (MSM8994) we used the following chain in order to disable the MMU Similarly to Nokia 6, we found the stack base address (0xFEC04000), dumped it, and chose a stored LR target (0xFEC03F88). In order to achieve a fast upload nevertheless, we used the following technique: for each poke we add another XML attribute, which encapsulates our data. I retrieved the file from another device which reports exactly the same HWID and PK_HASH as yours and I found this group by complete accident. For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). So, let's collect the knowledge base of the loaders in this thread. In the case of Qualcomm , these programmers are referred to as " firehose >" binaries. Using the same mechanism, some devices (primarily Xiaomi ones) also allowed/allow to reboot into EDL from fastboot, either by issuing fastboot oem edl, or with a proprietary fastboot edl command (i.e with no oem). So breakpoints are simply placed by replacing instructions with undefined ones which cause the undefined instruction handler, that we hooked, to be executed. To defeat that, we devised a ROP chain that disables the MMU itself! I know that some of them must work at least for one 8110 version. If the author of the solution wants to disclose any information, we can do this as well and give him credits, but for now the origins remain a secret (to protect both us and him). Please empty this comment field to prove you're human. For Nokia 6 (aarch32), for example, we get the following UART log, that indicates we are in EL3: The Nexus 6P (angler) aarch64 programmer also runs in EL3: OnePlus 5s programmer, on the other hand, runs in EL1: We can see that the most recent programmer has the least privilege level, a good sign from Qualcomm. For aarch64 - CurrentEL, for aarch32 - CPSR.M. Alcatel Onetouch Idol 3. If your device is semi bricked and entered the usb pid 0x900E, there are several options You also wouldnt want your device to turn off while youre flashing the firmware, which could lead to unexpected results. Ok, let's forget about 2720 for now. The EDL mode itself implements the Qualcomm Sahara protocol, which accepts an OEM-digitally-signed programmer (an ELF binary in recent devices, MBN in older ones) over USB, that acts as an SBL. To boot your phone into EDL mode using the test point method, you will need to expose the devices mainboard and use a metal tweezer (or a conductive metal wire) to short the points, and then plug the device to your PC or to the wall charger over USB. Some fields worth noting include sbl_entry which is later set to the SBLs entry point, and pbl2sbl_data which contains parameters passed to the soon-to-be-jumped-to SBL (see next). The first research question that we came up with was what exception (privilege) level we ran under: To answer our research question, we could read relevant registers. For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). Unlike Fastboot, Download, and Recovery modes on Android, which reside in the Secondary Bootloader (SBL), PBL resides within the ROM and so it could not be corrupted due to software errors (again, like a wrong flash). So, I know the only file from this archive for sure: Filename: prog_emmc_firehose_8909_alcF.mbn. In Part 2, we discuss storage-based attacks exploiting a functionality of EDL programmers we will see a few concrete examples such as unlocking the Xiaomi Note 5A (codename ugglite) bootloader in order to install and load a malicious boot image thus breaking the chain-of-trust. This cleared up so much fog and miasma..;-). Here is the Jiophone 2 firehose programmer. In order to further understand the memory layout of our devices, we dumped and parsed their page tables. We're now entering a phase where fundamental things have to be understood. We then present our exploit framework, firehorse, which implements a runtime debugger for firehose programmers (Part 4). ), youll need to use the test point method. EDL implements Qualcomms Sahara or Firehose protocol (on modern devices) to accept OEM-digitally-signed programmer in ELF file format (or in MBN file format on older devices). On Linux or macOS: Launch the Terminal and change its directory to the platform-tools folder using the cd command. In the next part we display the cherry on top a complete Secure Boot exploit against Nokia 6 MSM8937. Yes, your device needs to be sufficiently charged to enter EDL mode. A usuable feature of our host script is that it can be fed with a list of basic blocks. To implement breakpoints, we decided to abuse undefined instruction exceptions. When such an exception occurs, a relevant handler, located at an offset from the vector base address, is called. Its often named something like prog_*storage. This is known as the EDL or Deep Flashing USB cable. As for remediation, vendors with leaked programmers should use Qualcomms Anti-Rollback mechanism, if applicable, in order to prevent them from being loaded by the Boot ROM (PBL), The problem is caused by customizations from OEMsOur Boot ROM supports anti-rollback mechanism for the firehose image., Exploiting Qualcomm EDL Programmers (5): Breaking Nokia 6's Secure Boot, Exploiting Qualcomm EDL Programmers (4): Runtime Debugger, Exploiting Qualcomm EDL Programmers (3): Memory-based Attacks & PBL Extraction, Exploiting Qualcomm EDL Programmers (2): Storage-based Attacks & Rooting, Exploiting Qualcomm EDL Programmers (1): Gaining Access & PBL Internals, Obtain and reverse-engineer the PBL of various Qualcomm-based chipsets (, Obtain the RPM & Modem PBLs of Nexus 6P (, Manifest an end-to-end attack against our Nokia 6 device running Snapdragon 425 (. ImageLoad is the function that is in charge of loading the next bootloaders, including ABOOT: ImageLoad starts by calling (using the loop_callbacks routine) a series of initialization functions: firehose_main eventually falls into the main firehose loop, and never returns. Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. At the beginning we naively implemented breakpoints for 2-byte Thumb instructions with 16-bit long invalid instructions (0xFFFF), however we soon realized it was problematic as they might actually result in valid 32-bit instructions, depending on the adjacent word. In Part 3 we exploit a hidden functionality of Firehose programmers in order to execute code with highest privileges (EL3) in some devices, allowing us, for example, to dump the Boot ROM (PBL) of various SoCs. The rest of our devices with an aarch32 programmer (Xiaomi Note 5A and Xiaomi Note 4) also had an WX page available, hence code execution on them was immediate as well. ), EFS directory write and file read has to be added (Contributions are welcome ! Finding the address of the execution stack. To have a better understanding, please take a look at the figures below. Launch the command-line tool in this same folder. (Part 3) <-- . Exploiting Qualcomm EDL Programmers (3): Memory-based Attacks & PBL Extraction. Later, the PBL will actually skip the SBL image loading, and go into EDL mode. The OEM flash tools can only communicate with a device and flash it through the said modes. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. We obtained and reverse-engineered the PBL of various Qualcomm-based chipsets (, We obtained the RPM & Modem PBLs of Nexus 6P (, We managed to unlock & root various Android Bootloaders, such as Xiaomi Note 5A, using a storage-based attack only. Connect the phone to your PC while its in Fastboot mode. Thanks for visiting us, Comment below if you face any problem With Qualcomm Prog eMMC Firehose Programmer file Download problem, we will try to solve your problem as soon as possible. For Oneplus 6T, enter #801# on dialpad, set Engineer Mode and Serial to on and try : Published under MIT license Generally if the devices software is corrupted due to a wrong flash or any other software issue, it could be revived by flashing the firmware through Fastboot and Download modes. CVE-2017-13174. Concretely, in the next chapters we will use and continue the research presented here, to develop: 73C51DE96B5F6F0EE44E40EEBC671322071BC00D705EEBDD7C60705A1AD11248, 74F3DE78AB5CD12EC2E77E35B8D96BD8597D6B00C2BA519C68BE72EA40E0EB79, D18EF172D0D45AACC294212A45FBA91D8A8431CC686B164C6F0E522D476735E9, 9B3184613D694EA24D3BEEBA6944FDB64196FEA7056C833D38D2EF683FD96E9B, 30758B3E0D2E47B19EBCAC1F0A66B545960784AD6D428A2FE3C70E3934C29C7A, 8D417EF2B7F102A17C2715710ABD76B16CBCE8A8FCEB9E9803733E731030176B, 02FFDAA49CF25F7FF287CAB82DA0E4F943CABF6E6A4BFE31C3198D1C2CFA1185, EEF93D29E4EDDA26CCE493B859E22161853439DE7B2151A47DAFE3068EE43ABE, A1B7EB81C61525D6819916847E02E9AE5031BF163D246895780BD0E3F786C7EE, 97EFF4D4111DD90523F6182E05650298B7AE803F0EC36F69A643C031399D8D13, C34EC1FDDFAC05D8F63EED3EE90C8E6983FE2B0E4B2837B30D8619A29633649C, 63A47E46A664CCD1244A36535D10CA0B97B50B510BD481252F786177197C3C44, 964B5C486B200AA6462733A682F9CEAD3EBFAD555CE2FF3622FEA8B279B006EE, 71C4F97535893BA7A3177320143AC94DB4C6584544C01B61860ACA80A477D4C9, CB06DECBE7B1C47D10C97AE815D4FB2A06D62983738D383ED69B25630C394DED, A27232BF1383BB765937AEA1EBDEE8079B8A453F3982B46F5E7096C373D18BB3, 3FDAF99FC506A42FCBC649B7B46D9BB8DD32AEABA4B56C920B45E93A4A7080EA, 48741756201674EB88C580DF1FDB06C7B823DC95B3FC89588A84A495E815FBD4, 8483423802d7f01bf1043365c855885b0eea193bf32ed25041a347bc80c32d6b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ooking to work with some programmers on getting some development going on this. Moreover, implementing support for adjacent breakpoints was difficult. In the previous part we explained how we gained code execution in the context of the Firehose programmer. As for the other devices we posses, that have aarch64 programmers, ROP-based exploitation was indeed needed, as no writable/executable pages were found, due to probably the employment of SCTLR.WXN, that disables execution on any writable page, regardless of its NX bit. This list can be generated using the following IDA Python script: For example, here is the list of basic blocks generated for the pbl_sense_jtag_test_edl function discussed in Part 1: Then, one can call our breakpoints managers break_function or trace_function in order to break on a functions entry, or break on all basic blocks, effectively tracing its execution. You can upload your own or analyze the files already uploaded to the thread, and let everyone know which model has which fitting firehose loader. GADGET 1 Our first gadget generously gives us control over X0-X30: GADGET 2: The next gadget call X4, which we control using GADGET 1: GADGET 3: We set X4 to 0xF03DF38, a gadget which writes X1 (which we control using GADGET 1) to the EL3 System Control Register (SCTLR_EL3): The LSB of SCTLR_EL3 controls the MMU (0 = disabled). ALEPH-2017029. Qualcomm's EDL & Firehose demystified. Mar 22, 2021 View. The routine sets the bootmode field in the PBL context. Now, boot your phone into Fastboot mode by using the buttons combination. You can Download and Use this file to remove Screen lock on Qualcomm Supports Devices, and Bypass FRP Google account on all Qualcomm Devices. This is done inside some_sahara_stuff which gets called if either pbl->bootmode is edl, or the flash initialization has failed: Later, when the PBL actually tries to load the SBL from the flash drive, it will consider the pbl->flash->initialized field and use the Sahara protocol instead: The PBL later jumps to the SBL entry point, with the aforementioned pbl2sbl_data: As mentioned above, modern EDL programmers implement the Qualcomm Firehose protocol. Our XML Hunter searches the relevant memory for such pokes, and decodes the data, contained in the supplied attribute. Must be easily downloadable (no turbobits/dfiles and other adware), preferably a direct link; 2. Onetouch Idol 3 Android Development . emmc Programs File. Some devices have an XBL (eXtensible Bootloader) instead of an SBL. All Qualcomm "Prog eMMC Firehose" Programmer file Download Qualcomm EMMC Prog Firehose files is a basic part of stock firmware for Qualcomm phones, It comes with .mbm extensions and stores the partition data, and verifies the memory partition size. I'm not sure if I'm using the right file, but I can see quite a bit of raw data being exchanged by using the client's --debug option. Let me start with my own current collection for today -. Luckily enough (otherwise, where is the fun in that? 1. Phones from Xiaomi and Nokia are more susceptible to this method. Home EMMC Files All Qualcomm Prog eMMC Firehose Programmer file Download. This should be the emmc programmer for your specific model. The availability of these test points varies from device to device, even if they are from the same OEM. To ensure that we can replace arbitrary instructions and not get hit with data aborts while doing so (due to non-writable pages), we either disable the MMU completely (aarch64), or in aarch32, much conveniently elevate all of the domains to manager, by writing 0xFFFFFFFF to the DACR register. Rahul, most (if not all) Xiaomi phones would need the third method to get into EDL mode. So, I have an idea how we could deal with this, and will check this idea tomorrow. CVE-2017 . Since their handling code is common, we can only guess that there exist some compilation flag that is kept enabled by the affected OEMs. Research & Exploitation framework for Qualcomm EDL Firehose programmers, By Roee Hay (@roeehay) & Noam Hadad, Aleph Reseserch, HCL Technologies. As for aarch64, we also have preliminary support for working with the MMU enabled, by controlling the relevant page table entries. The first part presents some internals of the PBL, EDL, Qualcomm Sahara and programmers, focusing on Firehose. After I learned about EDL mode on the Cingular Flip 2, I discovered that it was useful on Android flip phones too. And the only way to reliably resist is to spread the information and the tools for low-level hardware access they can't easily change on their whim. To do so, we devised a ROP-based exploit, in order to leak the TTBR0 register, which holds the base address of the page table. In that case, youre left with only one option, which is to short the test points on your devices mainboard. While its best you use a firmware which includes a programmer file, you can (in severe cases) use the programmer file for a Qualcomm EDL mode varies across Qualcomm devices so. Qualcomm Firehose Programmer file Collection: Download Prog_firehose files for All Qualcomm SoC. The said protocol (s) can then accept commands from a PC over USB to flash the firmware on a device using tools like QPST, QFIL, MSMDownload, etc. As one can see, there are such pages already available for us to abuse. It can be found online fairly easily though. HWID: 0x000940e100420050 (MSM_ID:0x000940e1,OEM_ID:0x0042,MODEL_ID:0x0050). Executing this chain, we managed to leak the TTBR0 register into a controlled memory address without crashing the device (by reconstructing the stack and returning to the original caller). EDL mode is entered by plugging the cable while having * and # pressed at the same time. When shorted during the boot, these test points basically divert the Primary Bootloader (PBL) to execute EDL mode. Thread starter sloshnmosh; Start date Jun 12, 2018; Forums. In addition, rebooting into EDL by software is done by asserting the LSB of the 0x193D100 register (also known as tcsr-boot-misc-detect) So, the file is indeed correct but it's deliberately corrupted. How to Enter EDL Mode on Qualcomm Android Devices, Method 3: By Shorting Hardware Test Points, Learn how to flash firmware files on Qualcomm Android devices using QPST Tool. Check below on the provided lists, If you cannot find your Device Model name, Just comment me below on this Post and be patient while I check & look for a suitable emmc file for your devices. to get back the 0x9008 mode : Use a edl cable (Short D+ with GND) and force reboot the phone (either vol up + power pressing for more than 20 seconds or disconnect battery), works with emmc + ufs flash (this will only work if XBL/SBL isn't broken). Android phones and tablets equipped with Qualcomm chipset contain a special boot mode which could be used force-flash firmware files for the purpose of unbricking or restoring the stock ROM. Seems like CAT is using generic HWID for 8909 devices We got very lucky with this. ignore the access righs completely). Catching breakpoints is only one side of the coin, the other recovery and execution of the original instruction. A domain set to manager instructs the MMU to always allow access (i.e. If it is in a bootloop or cannot enter the OS, move to the second method. Knowing the memory-layout of the programmers, and the running exception level, we started peeking around. EDL mode implements the Qualcomm Sahara protocol, which accepts a digitally-signed programmer (an ELF binary in recent devices), that acts as a Second-stage bootloader. Of course, the credits go to the respective source. ), this should not be as easy, as we expected the programmer to employ non-executable pages in order to protect against such a trivial exploit. bricked citrus dead after restart edl authentication firehose . For example, here are the Test Points on our Xiaomi Note 5A board: In addition, if the PBL fails to verify the SBL, or fails to initialize the flash, it will fall-back into EDL, and again, by using our research tool we found the relevant code part in the PBL that implements this. Although we can peek at arbitrary memory locations (and this is how we leaked TTBR0 from the Nokia 6 programmer), its both inconvenient and insufficient, as our code may crash the device, making debugging extremely painful. Extract the downloaded ZIP file to an easily accessible location on your PC. The signed certificates have a root certificate anchored in hardware. Therefore, this kind of attack requires the following: Finding the memory location of the execution stack is relatively easy, as this is set in the reset interrupt handler of the programmer: Next, we dumped the stack and searched for saved LR candidates for replacement: We chose 0x0802049b the programmer has a main-loop that waits for incoming XMLs through USB (handle_input from Part 1), so our replaced LR value is the return location to that loop from the XML command parser : Poking the corresponding stack location (0x805cfdc) with an arbitrary address should hijack the execution flow. https://alephsecurity.com/2018/01/22/qualcomm-edl-1/, https://github.com/alephsecurity/firehorse, [TOOL] Sahara & Firehose Test (Alcatel Flasher oncoming ), [ROM/FIRMWARE][6045X] Android 6.0 Marshmallow for Alcatel Onetouch Idol 3 5.5, [6039] - ***GUIDE*** - How to return the fastboot commands on already upgraded device, [ROM] 6045Y-DCZ - 6.0.1 stock, root, debloat - 2.2 (2016-08-09), [ROM][6045X][7.1.2][Resurrection Remix][5.8.5][Nougat][UNOFFICIAL][FINAL] IDOL 3 5.5, How to fix - cannot boot into system after /vendor changed file system (ext2, ext4), Junsun V1 Pro MTK8259 4GB + 64GB Android 10 headunit, Junsun V1 Pro (MTK8259/MTK8257) - firmware. The first part presents some internals of the PBL, GitHub Stars program. Further, we will also guide you on how to enter EDL mode on supported Qualcomm Android devices using ADB, Fastboot, or by manually shorting the hardware test points. r"C:\Program Files (x86)\Qualcomm\QPST437\bin\fh_loader.exe", r"C:\Program Files (x86)\Qualcomm\QPST437\bin\QSaharaServer.exe". GADGET 2: We get control of R4-R12,LR using the following gadget: Controlling LR allows us to set the address of the next gadget - 0x0801064B. Butunfortunatelydoesn'tseemtowork. I have an oppo made android mobile phone model no CPH1901 and want to put it into EDL mode try above mentioned methods using ADB but get not responding results. To achieve code execution within the programmer, we hoped to find an writable and executable memory page, which we will load our code into, and then replace some stored LR in the execution stack to hijack the control flow. Without which, booting into modes like Fastboot or Download modes wouldnt be possible. (Later we discovered that this was not necessary because we also statically found that address in the PBL & Programmer binaries.) Some OEMs (e.g. Rebooting into EDL can also happen from the Platform OS itself, if implemented, and if adb access is allowed, by running adb reboot edl. The source is pretty much verified. My proposed format is the following: - exact model name. I've discovered a few that are unfused (Orbic Journey, Coolpad Snap, and Schok Classic). Does this mean, the firehose should work? As soon as the command is entered, your phone will enter Emergency Download Mode. No, that requires knowledge of the private signature keys. It soon loads the digitally-signed SBL to internal memory (imem), and verifies its authenticity. XDA Developers was founded by developers, for developers. $ ./edl.py Qualcomm Sahara / Firehose Client V3.3 (c) B.Kerler 2018-2021. main - Trying with no loader given . Next, set the CROSS_COMPILE_32 and CROSS_COMPILE_64 enviroment vars as follows: Then call make and the payload for your specific device will be built. - HWID (if known) - exact filename (in an already uploaded archive) or a URL (if this is a new one) Requirements to the files: 1. It seems like EDL mode is only available for a split second and then turn off. EDL is implemented by the PBL. Research & Exploitation of Qualcomm EDL Firehose Programmers: From PBL (Boot ROM) Extraction, Research & Analysis to Secure Boot Bypass in Nokia 6. . The init function is in charge of the following: This struct contains the following fields: (The shown symbols are of course our own estimates.). Meaninganyworkingloader,willworkonbothofthem(andhopefullyfortheotheronesaswell). Modern such programmers implement the Firehose protocol, analyzed next. therefore we can simply load arbitrary code in such pages, and force the execution towards that code for Nokia 6, ROP was not needed after all! We often like to refer to this device state as a Hard-brick. This error is often a false-positive and can be ignored as your device will still enter EDL. Sylvain, if you know HWID of JioPhone 2, could you pls post it as well? Doing so will allow us to research the programmer in runtime. To know about your device-specific test points, you would need to check up on online communities like XDA. Xiaomi) also publish them on their official forums. Therefore, the address of the next gadget (0x8008D38) should be written to ORIGINAL_SP + 4 + 0x118 + 20 (R4-R8). Connect the device to your PC using a USB cable. Deeper down the rabbit hole, analyzing firehose_main and its descendants sheds light on all of the Firehose-accepted XML tags.

Exploiting Qualcomm EDL Programmers (2): Storage-based Attacks & Rooting Exploiting Qualcomm EDL Programmers (3): Memory-based Attacks & PBL Extraction Exploiting Qualcomm EDL Programmers (4): Runtime Debugger Exploiting Qualcomm EDL Programmers (5): Breaking Nokia 6's Secure Boot Usage Prerequisites To use this tool you'll need: Nokia 6/5 and old Xiaomi SBLs), and reboot into EDL if these pins are shortened. Moving to 32-bit undefined instructions regardless of the original instructions size has not solved the issue either our plan was to recover the adjacent word while dealing with the true breakpoint, without any side-effects whatsoever. Anyway, peek and poke are the holy grail of primitives that attackers creatively gain by exploiting vulnerabilities. Some SBLs may also reboot into EDL if they fail to verify that images they are in charge of loading. This method has a small price to pay.
qualcomm edl firehose programmers
And thus, there would be no chance of flashing the firmware to revive/unbrick the device. For example, for Nexus 6P (MSM8994) we used the following chain in order to disable the MMU Similarly to Nokia 6, we found the stack base address (0xFEC04000), dumped it, and chose a stored LR target (0xFEC03F88). In order to achieve a fast upload nevertheless, we used the following technique: for each poke we add another XML attribute, which encapsulates our data. I retrieved the file from another device which reports exactly the same HWID and PK_HASH as yours and I found this group by complete accident. For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). So, let's collect the knowledge base of the loaders in this thread. In the case of Qualcomm , these programmers are referred to as " firehose >" binaries. Using the same mechanism, some devices (primarily Xiaomi ones) also allowed/allow to reboot into EDL from fastboot, either by issuing fastboot oem edl, or with a proprietary fastboot edl command (i.e with no oem). So breakpoints are simply placed by replacing instructions with undefined ones which cause the undefined instruction handler, that we hooked, to be executed. To defeat that, we devised a ROP chain that disables the MMU itself! I know that some of them must work at least for one 8110 version. If the author of the solution wants to disclose any information, we can do this as well and give him credits, but for now the origins remain a secret (to protect both us and him). Please empty this comment field to prove you're human. For Nokia 6 (aarch32), for example, we get the following UART log, that indicates we are in EL3: The Nexus 6P (angler) aarch64 programmer also runs in EL3: OnePlus 5s programmer, on the other hand, runs in EL1: We can see that the most recent programmer has the least privilege level, a good sign from Qualcomm. For aarch64 - CurrentEL, for aarch32 - CPSR.M. Alcatel Onetouch Idol 3. If your device is semi bricked and entered the usb pid 0x900E, there are several options You also wouldnt want your device to turn off while youre flashing the firmware, which could lead to unexpected results. Ok, let's forget about 2720 for now. The EDL mode itself implements the Qualcomm Sahara protocol, which accepts an OEM-digitally-signed programmer (an ELF binary in recent devices, MBN in older ones) over USB, that acts as an SBL. To boot your phone into EDL mode using the test point method, you will need to expose the devices mainboard and use a metal tweezer (or a conductive metal wire) to short the points, and then plug the device to your PC or to the wall charger over USB. Some fields worth noting include sbl_entry which is later set to the SBLs entry point, and pbl2sbl_data which contains parameters passed to the soon-to-be-jumped-to SBL (see next). The first research question that we came up with was what exception (privilege) level we ran under: To answer our research question, we could read relevant registers. For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). Unlike Fastboot, Download, and Recovery modes on Android, which reside in the Secondary Bootloader (SBL), PBL resides within the ROM and so it could not be corrupted due to software errors (again, like a wrong flash). So, I know the only file from this archive for sure: Filename: prog_emmc_firehose_8909_alcF.mbn. In Part 2, we discuss storage-based attacks exploiting a functionality of EDL programmers we will see a few concrete examples such as unlocking the Xiaomi Note 5A (codename ugglite) bootloader in order to install and load a malicious boot image thus breaking the chain-of-trust. This cleared up so much fog and miasma..;-). Here is the Jiophone 2 firehose programmer. In order to further understand the memory layout of our devices, we dumped and parsed their page tables. We're now entering a phase where fundamental things have to be understood. We then present our exploit framework, firehorse, which implements a runtime debugger for firehose programmers (Part 4). ), youll need to use the test point method. EDL implements Qualcomms Sahara or Firehose protocol (on modern devices) to accept OEM-digitally-signed programmer in ELF file format (or in MBN file format on older devices). On Linux or macOS: Launch the Terminal and change its directory to the platform-tools folder using the cd command. In the next part we display the cherry on top a complete Secure Boot exploit against Nokia 6 MSM8937. Yes, your device needs to be sufficiently charged to enter EDL mode. A usuable feature of our host script is that it can be fed with a list of basic blocks. To implement breakpoints, we decided to abuse undefined instruction exceptions. When such an exception occurs, a relevant handler, located at an offset from the vector base address, is called. Its often named something like prog_*storage. This is known as the EDL or Deep Flashing USB cable. As for remediation, vendors with leaked programmers should use Qualcomms Anti-Rollback mechanism, if applicable, in order to prevent them from being loaded by the Boot ROM (PBL), The problem is caused by customizations from OEMsOur Boot ROM supports anti-rollback mechanism for the firehose image., Exploiting Qualcomm EDL Programmers (5): Breaking Nokia 6's Secure Boot, Exploiting Qualcomm EDL Programmers (4): Runtime Debugger, Exploiting Qualcomm EDL Programmers (3): Memory-based Attacks & PBL Extraction, Exploiting Qualcomm EDL Programmers (2): Storage-based Attacks & Rooting, Exploiting Qualcomm EDL Programmers (1): Gaining Access & PBL Internals, Obtain and reverse-engineer the PBL of various Qualcomm-based chipsets (, Obtain the RPM & Modem PBLs of Nexus 6P (, Manifest an end-to-end attack against our Nokia 6 device running Snapdragon 425 (. ImageLoad is the function that is in charge of loading the next bootloaders, including ABOOT: ImageLoad starts by calling (using the loop_callbacks routine) a series of initialization functions: firehose_main eventually falls into the main firehose loop, and never returns. Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. At the beginning we naively implemented breakpoints for 2-byte Thumb instructions with 16-bit long invalid instructions (0xFFFF), however we soon realized it was problematic as they might actually result in valid 32-bit instructions, depending on the adjacent word. In Part 3 we exploit a hidden functionality of Firehose programmers in order to execute code with highest privileges (EL3) in some devices, allowing us, for example, to dump the Boot ROM (PBL) of various SoCs. The rest of our devices with an aarch32 programmer (Xiaomi Note 5A and Xiaomi Note 4) also had an WX page available, hence code execution on them was immediate as well. ), EFS directory write and file read has to be added (Contributions are welcome ! Finding the address of the execution stack. To have a better understanding, please take a look at the figures below. Launch the command-line tool in this same folder. (Part 3) <-- . Exploiting Qualcomm EDL Programmers (3): Memory-based Attacks & PBL Extraction. Later, the PBL will actually skip the SBL image loading, and go into EDL mode. The OEM flash tools can only communicate with a device and flash it through the said modes. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. We obtained and reverse-engineered the PBL of various Qualcomm-based chipsets (, We obtained the RPM & Modem PBLs of Nexus 6P (, We managed to unlock & root various Android Bootloaders, such as Xiaomi Note 5A, using a storage-based attack only. Connect the phone to your PC while its in Fastboot mode. Thanks for visiting us, Comment below if you face any problem With Qualcomm Prog eMMC Firehose Programmer file Download problem, we will try to solve your problem as soon as possible. For Oneplus 6T, enter #801# on dialpad, set Engineer Mode and Serial to on and try : Published under MIT license Generally if the devices software is corrupted due to a wrong flash or any other software issue, it could be revived by flashing the firmware through Fastboot and Download modes. CVE-2017-13174. Concretely, in the next chapters we will use and continue the research presented here, to develop: 73C51DE96B5F6F0EE44E40EEBC671322071BC00D705EEBDD7C60705A1AD11248, 74F3DE78AB5CD12EC2E77E35B8D96BD8597D6B00C2BA519C68BE72EA40E0EB79, D18EF172D0D45AACC294212A45FBA91D8A8431CC686B164C6F0E522D476735E9, 9B3184613D694EA24D3BEEBA6944FDB64196FEA7056C833D38D2EF683FD96E9B, 30758B3E0D2E47B19EBCAC1F0A66B545960784AD6D428A2FE3C70E3934C29C7A, 8D417EF2B7F102A17C2715710ABD76B16CBCE8A8FCEB9E9803733E731030176B, 02FFDAA49CF25F7FF287CAB82DA0E4F943CABF6E6A4BFE31C3198D1C2CFA1185, EEF93D29E4EDDA26CCE493B859E22161853439DE7B2151A47DAFE3068EE43ABE, A1B7EB81C61525D6819916847E02E9AE5031BF163D246895780BD0E3F786C7EE, 97EFF4D4111DD90523F6182E05650298B7AE803F0EC36F69A643C031399D8D13, C34EC1FDDFAC05D8F63EED3EE90C8E6983FE2B0E4B2837B30D8619A29633649C, 63A47E46A664CCD1244A36535D10CA0B97B50B510BD481252F786177197C3C44, 964B5C486B200AA6462733A682F9CEAD3EBFAD555CE2FF3622FEA8B279B006EE, 71C4F97535893BA7A3177320143AC94DB4C6584544C01B61860ACA80A477D4C9, CB06DECBE7B1C47D10C97AE815D4FB2A06D62983738D383ED69B25630C394DED, A27232BF1383BB765937AEA1EBDEE8079B8A453F3982B46F5E7096C373D18BB3, 3FDAF99FC506A42FCBC649B7B46D9BB8DD32AEABA4B56C920B45E93A4A7080EA, 48741756201674EB88C580DF1FDB06C7B823DC95B3FC89588A84A495E815FBD4, 8483423802d7f01bf1043365c855885b0eea193bf32ed25041a347bc80c32d6b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ooking to work with some programmers on getting some development going on this. Moreover, implementing support for adjacent breakpoints was difficult. In the previous part we explained how we gained code execution in the context of the Firehose programmer. As for the other devices we posses, that have aarch64 programmers, ROP-based exploitation was indeed needed, as no writable/executable pages were found, due to probably the employment of SCTLR.WXN, that disables execution on any writable page, regardless of its NX bit. This list can be generated using the following IDA Python script: For example, here is the list of basic blocks generated for the pbl_sense_jtag_test_edl function discussed in Part 1: Then, one can call our breakpoints managers break_function or trace_function in order to break on a functions entry, or break on all basic blocks, effectively tracing its execution. You can upload your own or analyze the files already uploaded to the thread, and let everyone know which model has which fitting firehose loader. GADGET 1 Our first gadget generously gives us control over X0-X30: GADGET 2: The next gadget call X4, which we control using GADGET 1: GADGET 3: We set X4 to 0xF03DF38, a gadget which writes X1 (which we control using GADGET 1) to the EL3 System Control Register (SCTLR_EL3): The LSB of SCTLR_EL3 controls the MMU (0 = disabled). ALEPH-2017029. Qualcomm's EDL & Firehose demystified. Mar 22, 2021 View. The routine sets the bootmode field in the PBL context. Now, boot your phone into Fastboot mode by using the buttons combination. You can Download and Use this file to remove Screen lock on Qualcomm Supports Devices, and Bypass FRP Google account on all Qualcomm Devices. This is done inside some_sahara_stuff which gets called if either pbl->bootmode is edl, or the flash initialization has failed: Later, when the PBL actually tries to load the SBL from the flash drive, it will consider the pbl->flash->initialized field and use the Sahara protocol instead: The PBL later jumps to the SBL entry point, with the aforementioned pbl2sbl_data: As mentioned above, modern EDL programmers implement the Qualcomm Firehose protocol. Our XML Hunter searches the relevant memory for such pokes, and decodes the data, contained in the supplied attribute. Must be easily downloadable (no turbobits/dfiles and other adware), preferably a direct link; 2. Onetouch Idol 3 Android Development . emmc Programs File. Some devices have an XBL (eXtensible Bootloader) instead of an SBL. All Qualcomm "Prog eMMC Firehose" Programmer file Download Qualcomm EMMC Prog Firehose files is a basic part of stock firmware for Qualcomm phones, It comes with .mbm extensions and stores the partition data, and verifies the memory partition size. I'm not sure if I'm using the right file, but I can see quite a bit of raw data being exchanged by using the client's --debug option. Let me start with my own current collection for today -. Luckily enough (otherwise, where is the fun in that? 1. Phones from Xiaomi and Nokia are more susceptible to this method. Home EMMC Files All Qualcomm Prog eMMC Firehose Programmer file Download. This should be the emmc programmer for your specific model. The availability of these test points varies from device to device, even if they are from the same OEM. To ensure that we can replace arbitrary instructions and not get hit with data aborts while doing so (due to non-writable pages), we either disable the MMU completely (aarch64), or in aarch32, much conveniently elevate all of the domains to manager, by writing 0xFFFFFFFF to the DACR register. Rahul, most (if not all) Xiaomi phones would need the third method to get into EDL mode. So, I have an idea how we could deal with this, and will check this idea tomorrow. CVE-2017 . Since their handling code is common, we can only guess that there exist some compilation flag that is kept enabled by the affected OEMs. Research & Exploitation framework for Qualcomm EDL Firehose programmers, By Roee Hay (@roeehay) & Noam Hadad, Aleph Reseserch, HCL Technologies. As for aarch64, we also have preliminary support for working with the MMU enabled, by controlling the relevant page table entries. The first part presents some internals of the PBL, EDL, Qualcomm Sahara and programmers, focusing on Firehose. After I learned about EDL mode on the Cingular Flip 2, I discovered that it was useful on Android flip phones too. And the only way to reliably resist is to spread the information and the tools for low-level hardware access they can't easily change on their whim. To do so, we devised a ROP-based exploit, in order to leak the TTBR0 register, which holds the base address of the page table. In that case, youre left with only one option, which is to short the test points on your devices mainboard. While its best you use a firmware which includes a programmer file, you can (in severe cases) use the programmer file for a Qualcomm EDL mode varies across Qualcomm devices so. Qualcomm Firehose Programmer file Collection: Download Prog_firehose files for All Qualcomm SoC. The said protocol (s) can then accept commands from a PC over USB to flash the firmware on a device using tools like QPST, QFIL, MSMDownload, etc. As one can see, there are such pages already available for us to abuse. It can be found online fairly easily though. HWID: 0x000940e100420050 (MSM_ID:0x000940e1,OEM_ID:0x0042,MODEL_ID:0x0050). Executing this chain, we managed to leak the TTBR0 register into a controlled memory address without crashing the device (by reconstructing the stack and returning to the original caller). EDL mode is entered by plugging the cable while having * and # pressed at the same time. When shorted during the boot, these test points basically divert the Primary Bootloader (PBL) to execute EDL mode. Thread starter sloshnmosh; Start date Jun 12, 2018; Forums. In addition, rebooting into EDL by software is done by asserting the LSB of the 0x193D100 register (also known as tcsr-boot-misc-detect) So, the file is indeed correct but it's deliberately corrupted. How to Enter EDL Mode on Qualcomm Android Devices, Method 3: By Shorting Hardware Test Points, Learn how to flash firmware files on Qualcomm Android devices using QPST Tool. Check below on the provided lists, If you cannot find your Device Model name, Just comment me below on this Post and be patient while I check & look for a suitable emmc file for your devices. to get back the 0x9008 mode : Use a edl cable (Short D+ with GND) and force reboot the phone (either vol up + power pressing for more than 20 seconds or disconnect battery), works with emmc + ufs flash (this will only work if XBL/SBL isn't broken). Android phones and tablets equipped with Qualcomm chipset contain a special boot mode which could be used force-flash firmware files for the purpose of unbricking or restoring the stock ROM. Seems like CAT is using generic HWID for 8909 devices We got very lucky with this. ignore the access righs completely). Catching breakpoints is only one side of the coin, the other recovery and execution of the original instruction. A domain set to manager instructs the MMU to always allow access (i.e. If it is in a bootloop or cannot enter the OS, move to the second method. Knowing the memory-layout of the programmers, and the running exception level, we started peeking around. EDL mode implements the Qualcomm Sahara protocol, which accepts a digitally-signed programmer (an ELF binary in recent devices), that acts as a Second-stage bootloader. Of course, the credits go to the respective source. ), this should not be as easy, as we expected the programmer to employ non-executable pages in order to protect against such a trivial exploit. bricked citrus dead after restart edl authentication firehose . For example, here are the Test Points on our Xiaomi Note 5A board: In addition, if the PBL fails to verify the SBL, or fails to initialize the flash, it will fall-back into EDL, and again, by using our research tool we found the relevant code part in the PBL that implements this. Although we can peek at arbitrary memory locations (and this is how we leaked TTBR0 from the Nokia 6 programmer), its both inconvenient and insufficient, as our code may crash the device, making debugging extremely painful. Extract the downloaded ZIP file to an easily accessible location on your PC. The signed certificates have a root certificate anchored in hardware. Therefore, this kind of attack requires the following: Finding the memory location of the execution stack is relatively easy, as this is set in the reset interrupt handler of the programmer: Next, we dumped the stack and searched for saved LR candidates for replacement: We chose 0x0802049b the programmer has a main-loop that waits for incoming XMLs through USB (handle_input from Part 1), so our replaced LR value is the return location to that loop from the XML command parser : Poking the corresponding stack location (0x805cfdc) with an arbitrary address should hijack the execution flow. https://alephsecurity.com/2018/01/22/qualcomm-edl-1/, https://github.com/alephsecurity/firehorse, [TOOL] Sahara & Firehose Test (Alcatel Flasher oncoming ), [ROM/FIRMWARE][6045X] Android 6.0 Marshmallow for Alcatel Onetouch Idol 3 5.5, [6039] - ***GUIDE*** - How to return the fastboot commands on already upgraded device, [ROM] 6045Y-DCZ - 6.0.1 stock, root, debloat - 2.2 (2016-08-09), [ROM][6045X][7.1.2][Resurrection Remix][5.8.5][Nougat][UNOFFICIAL][FINAL] IDOL 3 5.5, How to fix - cannot boot into system after /vendor changed file system (ext2, ext4), Junsun V1 Pro MTK8259 4GB + 64GB Android 10 headunit, Junsun V1 Pro (MTK8259/MTK8257) - firmware. The first part presents some internals of the PBL, GitHub Stars program. Further, we will also guide you on how to enter EDL mode on supported Qualcomm Android devices using ADB, Fastboot, or by manually shorting the hardware test points. r"C:\Program Files (x86)\Qualcomm\QPST437\bin\fh_loader.exe", r"C:\Program Files (x86)\Qualcomm\QPST437\bin\QSaharaServer.exe". GADGET 2: We get control of R4-R12,LR using the following gadget: Controlling LR allows us to set the address of the next gadget - 0x0801064B. Butunfortunatelydoesn'tseemtowork. I have an oppo made android mobile phone model no CPH1901 and want to put it into EDL mode try above mentioned methods using ADB but get not responding results. To achieve code execution within the programmer, we hoped to find an writable and executable memory page, which we will load our code into, and then replace some stored LR in the execution stack to hijack the control flow. Without which, booting into modes like Fastboot or Download modes wouldnt be possible. (Later we discovered that this was not necessary because we also statically found that address in the PBL & Programmer binaries.) Some OEMs (e.g. Rebooting into EDL can also happen from the Platform OS itself, if implemented, and if adb access is allowed, by running adb reboot edl. The source is pretty much verified. My proposed format is the following: - exact model name. I've discovered a few that are unfused (Orbic Journey, Coolpad Snap, and Schok Classic). Does this mean, the firehose should work? As soon as the command is entered, your phone will enter Emergency Download Mode. No, that requires knowledge of the private signature keys.
