For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). I'm working on running a standalone firehose programmer elf binary within Docker (for research purposes) I have the container building and has all the tools I need to get started (readelf, gdb, strings) and all the aarch64 emulation that should be needed to run the programmer. In order to tackle that, we abused the Firehose protocol in the following ways: Egg Hunting. An abstract overview of the boot process of Qualcomm MSM devices is as follows: The PBL kicks-in from ROM after the device is powered-on. Nokia 800 Tough seems to have the same HWID. (Later we discovered that this was not necessary because we also statically found that address in the PBL & Programmer binaries.) TA-1048, TA-1059 or something else? To defeat that, we devised a ROP chain that disables the MMU itself! Thats it! 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. The programmer implements the Firehose protocol which allows the host PC to send commands to write into the onboard storage (eMMC, UFS). Why not reconstruct the 32-bit page table? To do this: On Windows: Open the platform-tools folder. Without which, booting into modes like Fastboot or Download modes wouldnt be possible. sahara - ----- HWID: 0x0005f0e100000000 (MSM_ID:0x0005f0e1,OEM_ID:0x0000,MODEL_ID:0x0000) CPU detected: "MSM8996Pro" PK_HASH . Knowing the memory-layout of the programmers, and the running exception level, we started peeking around. I dont think the mother board is receiving power as the battery is dead. on this page we share more then 430 Prog_firehose files from different devices & SoC for both EMMC and UFS devices, You can use according your Requirement's. Note: use at own risk How to use: use with supported Box use with qfil Downloads: In addition, rebooting into EDL by software is done by asserting the LSB of the 0x193D100 register (also known as tcsr-boot-misc-detect) This very poor throughput is due to the fact that each poke only allows uploading 8 bytes (encoded as 16 bytes) at a time, with 499 pokes per XML. Improved streaming stuff, Qualcomm Sahara / Firehose Attack Client / Diag Tools. Therefore, the address of the next gadget (0x8008D38) should be written to ORIGINAL_SP + 4 + 0x118 + 20 (R4-R8). Since we gained code execution in either EL3 or EL1, we can easily catch ARM exceptions. You can Download and Use this file to remove Screen lock on Qualcomm Supports Devices, and Bypass FRP Google account on all Qualcomm Devices, Qualcomm Prog eMMC Firehose Programmer file Download, Lava V62 Benco FRP File Download (Bypass Google) by SPD Research Tool Latest Free, DarkRa1n iCloud Bypass Tool iOS 16 iOS 15 Download Free Latest, VNROM FILE Ramdisk Tool Download Windows Latest Version Free, Mina Ramdisk Bypass Tool V1.3 Download Latest Version for MAC Free, GSM Gaster Tool V4.0 Download Latest Passcode, Hello Screen Disable Device, OMH Mi Blu Relock Fixer Tool V1 Download Latest Version Free, iOS Factory Reset Tool V1 Download latest version Free, CICADA iTools V4.1 Download Latest Version Setup Free, Oppo A11s No Auth Loader Firehose File Download Free, Motorola G Stylus 5G EDL Firehose Programmer File Download Free. First, edit the Makefile in the device directory - set the device variable to whatever device you want (nokia6, angler, ugglite, mido and cheeseburger are currently supported). A natural continuation of this research is gaining arbitrary code execution in the context of the programmer itself. Luckily, by revisiting the binary of the first level page table, we noticed that it is followed by 32-bit long entires (from offset 0x20), The anglers programmer is a 64-bit one, so clearly the 32-bit entries do not belong here. A domain set to manager instructs the MMU to always allow access (i.e. As mentioned above, modern EDL programmers implement the Qualcomm Firehose protocol. 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. The signed certificates have a root certificate anchored in hardware. please provide me with the package including the procedure please I need to unbrick my Nokia 8110-4g. Debuggers that choose this approach (and not for example, emulate the original instruction while leaving the breakpoint intact), must conduct a single-step in order to place the breakpoint once again. If it is in a bootloop or cannot enter the OS, move to the second method. XDA Developers was founded by developers, for developers. Exploiting Qualcomm EDL Programmers (1): Gaining Access & PBL Internals, 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, Qualcomm Product Support Tools (QPST - we used version 2.7.437 running on a windows 10 machine), A Cross compiler to build the payload for the devices (we used, set COM to whatever com port the device is connnected to, set FH_LOADER with a path to the fh_loader.exe in the QPST\bin directory, set SAHARA_SERVER with a path to the QSaharaServer.exe in the QPST\bin directory. One significant problem we encountered during the development of the debugger is that upload rate over poke is extremely slow. For a better experience, please enable JavaScript in your browser before proceeding. Qualcomm's EDL & Firehose demystified. (TheyactuallybothhaveadifferentOEMhash,whichprobablymeanstheyaredifferentlysigned,no?). One possible explanation for their existence is that they are old entries from the APPS PBL (which indeed sets TTBR0 to 0xFE800000). 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) If emmc flash is used, remove battery, short DAT0 with gnd, connect battery, then remove short. We then continued by exploring storage-based attacks. EDL, is implemented by the Primary Bootloader (PBL), allows to escape from the unfortunate situation where the second stage bootloader (stored in flash) is damaged. As open source tool (for Linux) that implements the Qualcomm Sahara and Firehose protocols has been developed by Linaro, and can be used for program (or unbrick) MSM based devices, such as Dragonboard 410c or Dragonboard 820c. To know about your device-specific test points, you would need to check up on online communities like XDA. As we witnessed in Part 1, oddly enough Firehose programmers implement the peek and poke XML tags, which according to our correspondence with Qualcomm, are customizations set by OEMs QPSIIR-909. 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. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Interestingly, there is a positive trend of blocking these commands in locked Android Bootloaders. As one can see, the relevant tag that instructs the programmer to flash a new image is program. This feature is used by our Nokia 6 exploit, since we need to relocate the debugger during the SBL to ABOOT transition. As an example, the figures below show these EDL test points on two different OEM devices Redmi Note 5A (on the left) and Nokia 6 (on the right). 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. Here is the Jiophone 2 firehose programmer. We believe other PBLs are not that different. . Some of these powerful capabilities are covered extensively throughout the next parts. 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). MSM (Qualcomms SoC)-based devices, contain a special mode of operation - Emergency Download Mode (EDL). Needless to mention, being able to reboot into EDL using software only means or with such USB cables (depict a charger that shortens the pins) enables dangerous attack vectors, such as malicious USB ports (e.g. Hold the SHIFT key on the keyboard and right-click on an empty space inside the folder. In that case, youre left with only one option, which is to short the test points on your devices mainboard. Ok, thanks for the info, let's not hurry then, I'm still going to upload a batch of new firehoses tonight so that we can test them worldwide. Sorry for the false alarm. To make any use of this mode, users must get hold of OEM-signed programmers, which seem to be publicly available for various such devices. Comment Policy: We welcome relevant and respectable comments. Part 3, Part 4 & Part 5 are dedicated for the main focus of our research memory based attacks. MSM-based devices contain a special mode of operation - Emergency Download Mode (EDL). You can Download and Use this file to remove Screen lock on Qualcomm Supports Devices, and Bypass FRP Google account on all Qualcomm Devices. Despite that, we can recover most breakpoints each time a breakpoint is hit, we simply reconstruct all of the others, losing only breakpoints that occur in succession. the Egg). 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: bricked citrus dead after restart edl authentication firehose . You also wouldnt want your device to turn off while youre flashing the firmware, which could lead to unexpected results. The first part presents some internals of the PBL, EDL, Qualcomm Sahara and programmers, focusing on Firehose. 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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utunfortunatelydoesn'tseemtowork. A usuable feature of our host script is that it can be fed with a list of basic blocks. The next part is solely dedicated for our runtime debugger, which we implemented on top of the building blocks presented in this part. 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. ), EFS directory write and file read has to be added (Contributions are welcome ! 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. For details on how to get into EDL, please see our blog post. 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. 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). In this part we extend the capabilities of firehorse even further, making it being able to debug Firehose programmers (both aarch32 and aarch64 ones) in runtime. Which version of 8110 do you have? Save my name, email, and website in this browser for the next time I comment. Analyzing several programmers binaries quickly reveals that commands are passed through XMLs (over USB). Programmers are pieces of low-level software containing raw flash/read-write functionality that allows for reflashing, similar to Samsung's Odin mode or LG's flash. 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. The figure on the right shows the boot process when EDL mode is executed. Now, boot your phone into Fastboot mode by using the buttons combination. * - Flashing 99% of, posiciones sexuales permitidas por la biblia, caramel recipe without corn syrup or candy thermometer, firehorse. Extract the downloaded ZIP file to an easily accessible location on your PC. Thats exactly when youd need to use EDL mode. You do not have permission to delete messages in this group, Either email addresses are anonymous for this group or you need the view member email addresses permission to view the original message. You will need to open the ufs die and short the clk line on boot, some boards have special test points for that. He has more than 6 years of experience in software and technology, obsessed with finding the best solution for a mobile device whether it is Apple or Android. or from here, Make a subdirectory "newstuff", copy your edl loaders to this subdirectory, or sniff existing edl tools using Totalphase Beagle 480, set filter to filter({'inputs': False, 'usb3': False, 'chirps': False, 'dev': 26, 'usb2resets': False, 'sofs': False, 'ep': 1}), export to binary file as "sniffeddata.bin" and then use beagle_to_loader sniffeddata.bin. Remove libusb1 for windows (libusb0 only), fix reset command, Fix sahara id handling and memory dumping, MDM9x60 support. these programmers are often leaked from OEM device repair labs. Nokia 6/5 and old Xiaomi SBLs), and reboot into EDL if these pins are shortened. Do you have Nokia 2720 flip mbn Or Nokia 800 tough mbn? Having a short glimpse at these tags is sufficient to realize that Firehose programmers go way beyond partition flashing. For example, on OnePlus 5: Now that we can conveniently receive output from the device, were finally ready for our runtime research. sbl maintains the SBL contextual data, where its first field points to a copy of pbl2sbl_data.
