), youll need to use the test point method. 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. Our XML Hunter searches the relevant memory for such pokes, and decodes the data, contained in the supplied attribute. CVE-2017-13174. As soon as the command is entered, your phone will enter Emergency Download 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. 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. 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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mageLoad 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. 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 ! Further updates on this thread will also be reflected at the special. So if anyone has any tips on how to find a loader for it (or for other Android flip phones, for that matter), I would be interested. 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). We also encountered SBLs that test the USB D+/GND pins upon boot (e.g. One significant problem we encountered during the development of the debugger is that upload rate over poke is extremely slow. In the next part we display the cherry on top a complete Secure Boot exploit against Nokia 6 MSM8937. JavaScript is disabled. If it is in a bootloop or cannot enter the OS, move to the second method. We could have not dumped everything because then we would risk in device hangs, reboots, etc, since some locations are not of the RAM. 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. Must be easily downloadable (no turbobits/dfiles and other adware), preferably a direct link; 2. 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. Comment Policy: We welcome relevant and respectable comments. A working 8110 4G firehose found, should be compatible with any version. 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. MSM-based devices contain a special mode of operation - Emergency Download Mode (EDL). As mentioned above, modern EDL programmers implement the Qualcomm Firehose protocol. Home EMMC Files All Qualcomm Prog eMMC Firehose Programmer file Download. My proposed format is the following: - exact model name. The OEM flash tools can only communicate with a device and flash it through the said modes. JusttriedonaTA-1071(singleSIM),doesn'tworkeither. Remove libusb1 for windows (libusb0 only), fix reset command, Fix sahara id handling and memory dumping, MDM9x60 support. 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. For example, if the folder in the Documents directory, the command should be: Now, enable USB debugging on your Android device using the instructions. 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. ABOOT prepares the kernel command line and initramfs parameters for the Linux kernel in the Device Tree Blob (DTB), and then transfers execution to the Android (Linux) kernel. Kindly please update whether it works as I'm on the same boat albeit with a different device (it's a projector with a battery based on android). Now, boot your phone into Fastboot mode by using the buttons combination. 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). This device has an aarch32 leaked programmer.

Before we do so, we need to somehow get output from the device. 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: 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). Specifically, the host uploads the following data structure, to FIREHORSE_BASE + ADDR_SCRATCH_OFFSET: The inner structures are described here (32 bit) and here (64 bit). CAT B35 loader found!

Some devices have an XBL (eXtensible Bootloader) instead of an SBL. Butunfortunatelydoesn'tseemtowork. I have the firehose/programmer for the LG V60 ThinQ. In addition, OnePlus 5s programmers runs in EL1, so we used SCTLR_EL1 instead of the EL3 counterpart. Sorry, couldn't talk to Sahara, please reboot the device ! In the case of Qualcomm , these programmers are referred to as " firehose >" binaries. 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. First, the PBL will mark the flash as uninitialized, by setting pbl->flash_struct->initialized = 0xA. 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. Once your Qualcomm Android device has entered EDL mode, you can connect it to the PC and use tools like QPST or QFIL to flash firmware files to unbrick or restore stock ROM. For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). A natural continuation of this research is gaining arbitrary code execution in the context of the programmer itself. In the previous part we explained how we gained code execution in the context of the Firehose programmer. 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.

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. Digging into the programmers code (Xiaomi Note 5A ugglite aarch32 programmer in this case) shows that its actually an extended SBL of some sort. GADGET 2: Similarly to the aarch32 case, we copy the original stack s.t. 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. Connect the device to your PC using a USB cable. In fact, thats one of the very common mistakes that users make when their device is bricked. Thread starter sloshnmosh; Start date Jun 12, 2018; Forums. We provide solutions: FRP Bypass, Firmware Flashing, IMEI repair, Unlock Bootloader, Rooting & many more stuff. Did a quick search and found the location of the test points on the Redmi 7A (Click to view the image). So follow me on social media: All Qualcomm Prog eMMC Firehose Programmer file Download, Today I will share you all Qualcomm EMMC Filehose Programmer file for Certain Devices, emmc Programs File download for all Qualcomm Chipsets Devices. Exploiting Qualcomm EDL Programmers (4): Runtime Debugger. (a=>{let b=document.getElementById(a.i),c=document.getElementById(a.w);b&&c&&(b.value="",c.style.display="none")})({"w":"a9f0b246da1895c7e","i":"a752a3f59ea684a35"}); Website#a752a3f59ea684a35735e6e1{display:none}. I've discovered a few that are unfused (Orbic Journey, Coolpad Snap, and Schok Classic). In addition, rebooting into EDL by software is done by asserting the LSB of the 0x193D100 register (also known as tcsr-boot-misc-detect) Of course, the credits go to the respective source. This gadget will return to GADGET 2. Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. So, thanks to anonymous Israeli volunteers, we now have a working firehose loader for all Nokia 2720 Flip variants. Interestingly, in the actual SBL of ugglite, this series of initialization callbacks looks as follows: Therefore, they only differ in the firehose_main callback! Credits & Activations. We then continued by exploring storage-based attacks. Research & Exploitation framework for Qualcomm EDL Firehose programmers, By Roee Hay (@roeehay) & Noam Hadad, Aleph Reseserch, HCL Technologies. Research & Exploitation framework for, A couple of years ago, it is easy to unbrick a Xiaomi device through Emergency Download Mode (, Programming & Flashing. This cleared up so much fog and miasma..;-). Interestingly, there is a positive trend of blocking these commands in locked Android Bootloaders. Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. Having a short glimpse at these tags is sufficient to realize that Firehose programmers go way beyond partition flashing. Catching breakpoints is only one side of the coin, the other recovery and execution of the original instruction. Since their handling code is common, we can only guess that there exist some compilation flag that is kept enabled by the affected OEMs. Alcatel. chargers). After running our chain, we could upload to and execute our payload at any writable memory location.
