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. 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). Qualcomm's EDL & Firehose demystified. The first part presents some internals of the PBL, GitHub Stars program. Improved streaming stuff, Qualcomm Sahara / Firehose Attack Client / Diag Tools. This cleared up so much fog and miasma..;-). I have the firehose/programmer for the LG V60 ThinQ. 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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art 3, Part 4 & Part 5 are dedicated for the main focus of our research memory based attacks. A natural continuation of this research is gaining arbitrary code execution in the context of the programmer itself. Exploiting Qualcomm EDL Programmers (4): Runtime Debugger. 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. First, the PBL will mark the flash as uninitialized, by setting pbl->flash_struct->initialized = 0xA. You signed in with another tab or window. Before we do so, we need to somehow get output from the device. ALEPH-2017029. Finally, enter the following command in the PowerShell window to boot your phone into EDL mode: If you see a prompt on the devices screen to allow USB debugging, press Allow. 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. Collection Of All Qualcomm EMMC Programmer Files Today I will share you all Qualcomm EMMC Filehose Programmer file for Certain Devices. Phones from Xiaomi and Nokia are more susceptible to this method. the last gadget will return to the original caller, and the device will keep processing Firehose commands. Knowing the memory-layout of the programmers, and the running exception level, we started peeking around. 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. Only unencrypted MSM8909-compatible format (the binary contents must start with ELF or "data ddc" signature).

We're now entering a phase where fundamental things have to be understood. Whether that file works for the Schok won't tell you much, Finding the address of the execution stack. The source is pretty much verified. 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. (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.). ABOOT then verifies the authenticity of the boot or recovery images, loads the Linux kernel and initramfs from the boot or recovery images. Some SBLs may also reboot into EDL if they fail to verify that images they are in charge of loading. Only input your real first name and valid email address if you want your comment to appear. 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. (Later we discovered that this was not necessary because we also statically found that address in the PBL & Programmer binaries.) ), 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. 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. Could anyone please test the attached firehose on 8110 4G (TA-1059 or TA-1048) or 2720 Flip? Let me start with my own current collection for today -. 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). 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. Please take a look at the image posted on this website, it illustrates the correct EDL test points for the Oppo A7. Which version of 8110 do you have? Finding the vector base address is a trivial task, as it can be done either statically, by reverse-engineering the programmers code, or even better - in runtime. 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. Without further complications we can simply reconstruct the original instruction in-place (after doing whatever we want we use this feature in the next chapter in order to conveniently defeat Nokia 6s secure boot, as it enables us to place hooks at the instruction level), and return from the exception. 1. (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}. 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. 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. Your device needs to have a usb pid of 0x9008 in order to make the edl tool work. To do this: On Windows: Open the platform-tools folder. Later, our UART output can be fed into IDA, using another IDA Python script, to mark the execution path. 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. So, let's collect the knowledge base of the loaders in this thread. main - Waiting for the device main - Device detected :) main - Mode detected: sahara Device is in EDL mode .. continuing. But newer Schok Classic phones seem to have a fused loader. Since we gained code execution in either EL3 or EL1, we can easily catch ARM exceptions. 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. The availability of these test points varies from device to device, even if they are from the same OEM. Our first target device was Nokia 6, that includes an MSM8937 SoC. Its 16-bit encoding is XXDE. - HWID (if known) - exact filename (in an already uploaded archive) or a URL (if this is a new one) Requirements to the files: 1. but edl mode is good choice, you should be able to wipe data and frp . 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: Xiaomi) also publish them on their official forums. 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? When in this mode, the device identifies itself as Qualcomm HS-USB QDLoader 9008 over a USB connection. So, the file is indeed correct but it's deliberately corrupted. JavaScript is disabled. For Oneplus 6T, enter #801# on dialpad, set Engineer Mode and Serial to on and try : Published under MIT license Tested on our Nexus 6P, trying to read from its PBL physical address (0xFC010000), instantly resulted in a system reboot. Rahul, most (if not all) Xiaomi phones would need the third method to get into EDL mode. The routine sets the bootmode field in the PBL context. 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. 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. Research & Exploitation framework for Qualcomm EDL Firehose programmers. 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. 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. In the previous chapters we presented Qualcomm Sahara, EDL and the problem of the leaked Firehose programmers. 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. This feature is used by our Nokia 6 exploit, since we need to relocate the debugger during the SBL to ABOOT transition. very, very useful! 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.
