Qualcomm Programmer eMMC UFS Firehose Download folder ArykTECH 349 subscribers Subscribe 40 Share 32K views 5 years ago In this video you will find complete list of available Qualcomm Programmer. The client does report the programmer successfully uploaded, but I suspect that's not true. Home EMMC Files All Qualcomm Prog eMMC Firehose Programmer file Download. Loading the programmer with IDA, quickly revealed that our obtained Firehose programmers also support the peek and poke tags, with the following format: These allow for arbitrary code execution in the context of the programmer, as demonstrated in our blog post. Individual loaders must have .mbn or .bin extension, archives should be preferably zip or 7z, no rar; 3. Analyzing several programmers' binaries quickly reveals that commands are passed through XMLs (over USB). Analyzing their handlers reveals the peek and poke tags expect the following format: Adding this to our research tool, allowed us to easily explore susceptible devices. On Linux or macOS: Launch the Terminal and change its directory to the platform-tools folder using the cd command. A partial list of available programmers we managed to obtain is given below: In this 5-part blog post we discuss the security implications of the leaked programmers. 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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you can check other tutorialshere to help. Luckily enough, for select chipsets, we soon encountered the PBL themselves: For example, the strings below are of the MSM8994 PBL (Nexus 6P): Please note that the PBL cannot be obtained by code running in the platform OS. Each of these routines plays an important role in the operation of the PBL. To start working with a specific device in EDL , you need a programmer . imem is a fast-on-chip memory used for debugging and dma (direct memory access) transactions and is proprietary to qualcomm chipsets. Why and when would you need to use EDL Mode? ABOOT then verifies the authenticity of the boot or recovery images, loads the Linux kernel and initramfs from the boot or recovery images. Nokia 800 Tough seems to have the same HWID. Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. 5 To gain access to EDL mode on your phone, follow the instructions below. Seems like CAT is using generic HWID for 8909 devices We got very lucky with this.

(Using our research framework we managed to pinpoint the exact location in the PBL that is in charge of evaluating these test points, but more on this next.). In aarch32, each page table entry specifies a domain number (a number from 0 to 15), that controls the way the MMU provisions that pages access rights. We presented our research framework, firehorse, and showed how we extracted the PBL of various SoCs. Must be easily downloadable (no turbobits/dfiles and other adware), preferably a direct link; 2. Thank you for this!! Hopefully we will then be able to find a suitable page (i.e one that is both writable and executable), or change (by poke) the access permissions of an existing one. Later, the PBL will actually skip the SBL image loading, and go into EDL mode. For aarch64 - CurrentEL, for aarch32 - CPSR.M. This isn't strictly speaking a Bananahackers question (because it's about Android phones), but this is where I learned about EDL mode. As one can see, there are such pages already available for us to abuse. The signed certificates have a root certificate anchored in hardware. Research & Exploitation of Qualcomm EDL Firehose Programmers: From PBL (Boot ROM) Extraction, Research & Analysis to Secure Boot Bypass in Nokia 6. . We presented our research framework, firehorse, and showed how we extracted the PBL of various SoCs. Triedonboth,8110&2720. We then present our exploit framework, firehorse, which implements a runtime debugger for firehose programmers (Part 4). 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. MSM (Qualcomm's SoC)-based devices, contain a special mode of operation - Emergency Download Mode (EDL). TA-1048, TA-1059 or something else? Qualcomm Sahara / Firehose Client (c) B.Kerler 2018-2019. 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. So breakpoints are simply placed by replacing instructions with undefined ones which cause the undefined instruction handler, that we hooked, to be executed. It seems the RPM PBL is in the 0xfc000000-0xfc0040000 range, where the MODEM PBL is in the 0xfc004000-0xfc010000 range. 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). Before that, we did some preliminary analysis of the MSM8937/MSM8917 PBL, in order to understand its layout in a high-level perspective. If emmc flash is used, remove battery, short DAT0 with gnd, connect battery, then remove short. Analyzing several programmers binaries quickly reveals that commands are passed through XMLs (over USB). You will need to open the ufs die and short the clk line on boot, some boards have special test points for that. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. The source is pretty much verified. Hi, 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. The client is able to at least communicate with my phone. We also encountered SBLs that test the USB D+/GND pins upon boot (e.g. Above both of the method (method 1 & method 2) are not working for Redmi 7a, Can you please confirm if i have to use Method 3: By Shorting Hardware Test Points to enter into EDL mode? Do you have Nokia 2720 flip mbn Or Nokia 800 tough mbn? Alcatel Onetouch Idol 3. Thats it! 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. Knowing the memory-layout of the programmers, and the running exception level, we started peeking around. 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. GADGET 2: Similarly to the aarch32 case, we copy the original stack s.t. HWID: 0x000940e100420050 (MSM_ID:0x000940e1,OEM_ID:0x0042,MODEL_ID:0x0050). initramfs is a cpio (gzipped) archive that gets loaded into rootfs (a RAM filesystem mounted at /) during the Linux kernel initialization. After that click on the select programmers path to browse and select the file. Note: The fastboot command mentioned above may sometimes return FAILED (Status read failed (Too many links)) error message. Catching breakpoints is only one side of the coin, the other recovery and execution of the original instruction. In this mode, the device identifies itself as Qualcomm HS-USB 9008 through USB. To start working with a specific device in EDL, you need a programmer. 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. I can't get it running, but I'm not sure, why. Later, in Part 5, we will see that this debugging functionality is essential for breaking Nokia 6s Secure Boot, allowing us to trace and place live patches in every part of its bootloader chain. However, we soon realized that there were many corner cases with that approach, such as setting breakpoints on instructions that cross their basic block boundary that could cause invalid breakpoints to be hit. 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). Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. GADGET 5: The next gadget copies R0 to [R4], which we can control using GADGET 2: We return from this gadget to the original caller. You signed in with another tab or window. GADGET 3: The next gadget calls R12 (that we control, using the previous gadget): GADGET 4: We set R12 to 080081AC, a gadget that copies TTBR0 to R0: This will return to GADGET 3, with R0 = TTBR0. All of these guides make use of Emergency Download Mode (EDL), an alternate boot-mode of the Qualcomm Boot ROM (Primary Bootloader). This method is for when your phone can boot into the OS and you want to boot it into EDL mode for restoring the stock firmware. The next part is solely dedicated for our runtime debugger, which we implemented on top of the building blocks presented in this part. (For debugging during our ROP chain development, we used gadgets that either reboot the device, or cause infinite loops, in order to indicate that our gadgets were indeed executed). 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. Our next goal was to be able to use these primitives in order to execute code within the programmer itself. A screwdriver and a paper clip - Used to force the device into EDL mode prog_ufs_firehose_8996_lite.elf - Firehose programmer file for use with the EDL utility Since the firehose programmer is copyright LG, I cannot link to it as that would be unauthorized distribution of copyrighted work. I'm using the Qualcomm Sahara/Firehose client on Linux. Qualcomm EDL Firehose Programmers Peek and Poke Primitives Aleph Research Advisory Identifier QPSIIR-909 Qualcomm ID QPSIIR-909 Severity Critical Product Qualcomm Technical Details MSM (Qualcomm's SoC)-based devices, contain a special mode of operation - Emergency Download Mode (EDL). In the Nokia 6 programmer (and maybe others as well), the result of the partition flashing process remains in the device memory, even after its complete. 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. First, the PBL will mark the flash as uninitialized, by setting pbl->flash_struct->initialized = 0xA. The only thing we need to take care of is copying the original stack and relocating absolute stack address. Anyway, peek and poke are the holy grail of primitives that attackers creatively gain by exploiting vulnerabilities. While the reason of their public availability is unknown, our best guess is that Since the programmer replaces the SBL itself, we expect that it runs in very high privileges (hopefully EL3), an assumption we will later be able to confirm/disprove once code execution is achieved. ), youll need to use the test point method. 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. Later, our UART output can be fed into IDA, using another IDA Python script, to mark the execution path. In this part we presented an arbitrary code execution attack against Firehose programmers. noidodroid Senior Member. Part 3, Part 4 & Part 5 are dedicated for the main focus of our research memory based attacks. Ive managed to fix a bootloop on my Mi A2. very, very useful! Doing so will allow us to research the programmer in runtime. When in this mode, the device identifies itself as Qualcomm HS-USB QDLoader 9008 over a USB connection. We must be at any moment prepared for organized resistance against the pressure from anyone trying to take away what's ours. I don't think I've ever had a Qualcomm EDL cable work on a single LG phone I have ever had over the past decade. I have made a working package for Nokia 8110 for flashing with cm2qlm module. Skipping the first 8 entries, that worked pretty well: Interestingly, the second level page table of 0xfc000000 is as follows: There is a noticeable hole from 0xfc000000 to 0xfc010000 (where the PBL begins), which does not exist in the 64-bit counterpart. A working 8110 4G firehose found, should be compatible with any version. Exploiting Qualcomm EDL Programmers (4): Runtime Debugger. Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. Some devices have an XBL (eXtensible Bootloader) instead of an SBL. 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. For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). It's already in the above archive. We reported this kind of exposure to some vendors, including OnePlus (CVE-2017-5947) and Google (Nexus 6/6P devices) - CVE-2017-13174. In order to tackle that, we abused the Firehose protocol in the following ways: Egg Hunting. Nokia 6/5 and old Xiaomi SBLs), and reboot into EDL if these pins are shortened. No, that requires knowledge of the private signature keys. In the previous part we explained how we gained code execution in the context of the Firehose programmer. but edl mode is good choice, you should be able to wipe data and frp . I must to tell you, I never, ever slow enough to comment on any site .but I was compelled to stop and say THANK YOU THANK YOU THANK . 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. Thats it! After that select the programmer file prog_emmc_firehose_8917_ddrMBN. MSM (Qualcomms SoC)-based devices, contain a special mode of operation - Emergency Download Mode (EDL). So can you configure a firehose for nokia 2720/800? Rahul, most (if not all) Xiaomi phones would need the third method to get into EDL mode. It can be found online fairly easily though. To know about your device-specific test points, you would need to check up on online communities like XDA. CAT B35 loader found! Remove libusb1 for windows (libusb0 only), fix reset command, Fix sahara id handling and memory dumping, MDM9x60 support. 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. And thus, there would be no chance of flashing the firmware to revive/unbrick the device. The routine that probes whether or not to go into EDL is pbl_sense_jtag_test_points_edl: By tracing through this code, we concluded that address 0xA606C contains the test points status (0x8000 <=> shortened). Improved streaming stuff, Qualcomm Sahara / Firehose Attack Client / Diag Tools. January 22, 2018 * QPSIIR-909. You can use it for multi-purpose on your Qualcomm powered phone such as Remove Screen lock, Flash Firmware, Remove FRP, Repair IMEI, also fix any type of error by the help of QPST/Qfil tool or any other third party repair tool, So, download basic firmware file or Prog EMMC MBN File from below. 62A1E772932EB33E86EE9A141403B78EF2D00F2C6848FE17213B92FCC7FAD1DF, E0B29ACCFF90D46023B449E071E74B1B0503FE704FD0DEFDE7317797601D9F31, 7E8BF70DFAD30A2C410EE91B301FACA9684677656F29F1E287C84360B149823A, B46518743470D2DF8B7DADE1561C87407D6DCE5CC489B88AC981C63078D82782, B674D3DC099E6D1A43D01055AA6089647594B9D455F32EF2238FB619CF67FF5C, 73A038CD54EB5F36C63555FDED82669D6FA98EF7EDA33417615DF481DD98BCFA, 4EF56F77DF83A006F97C5E4AB2385431F573F4F120C1B452D414F01EDA40F637, C073E07C7444C2A1C6E4BFFDBB0D7ABE8E6CB3AB68B2C5F2FA932AC6BBADF360, BE783DC133326E22D06823A335C1AEA0A3E544B4421A407263C9941DB6EA4E0C. Install normal QC 9008 Serial Port driver (or use default Windows COM Port one, make sure no exclamation is seen), Test on device connect using "UsbDkController -n" if you see a device with pid 0x9008, Copy all your loaders into the examples directory, Or rename Loaders manually as "msmid_pkhash[8 bytes].bin" and put them into the Loaders directory, Send AT!BOOTHOLD and AT!QPSTDLOAD to modem port or use, Send AT!ENTERCND="A710" and then AT!EROPTION=0 for memory dump, Secure loader with SDM660 on Xiaomi not yet supported (EDL authentification), VIP Programming not supported (Contributions are welcome ! In this mode, the device identifies itself as Qualcomm HS-USB 9008 through USB. The debuggers base address is computed in runtime (init_set_fh_entry()), and any absolute address is calculated as an offset from that base. We could have not dumped everything because then we would risk in device hangs, reboots, etc, since some locations are not of the RAM. But newer Schok Classic phones seem to have a fused loader. We guess that the Boot ROM can only be obtained from the secure state (which anglers programmer runs under). Programmer binaries are used by Qualcomm's Sahara protocol, which works in Emergency Download mode, commonly known as EDL, and is responsible for flashing a given device with a specific SoC.As a developer on GitHub claims, programmers are SoC specific but devices only. Read our comment policy fully before posting a comment. Apr 1, 2019 350 106 Innernetz www.noidodroid.com . 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).
