qualcomm edl firehose programmers

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. We're now entering a phase where fundamental things have to be understood. In order to further understand the memory layout of our devices, we dumped and parsed their page tables. Qualcomm Firehose Programmer file Collection: Download Prog_firehose files for All Qualcomm SoC. This should be the emmc programmer for your specific model. Alcatel Onetouch Idol 3. However, thats not the case always. 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. (, We managed to manifest an end-to-end attack against our Nokia 6 device running Snapdragon 425 (, It resets the MMU and some other system registers, in a function we named. Luckily for us, it turns out that most Android devices expose a UART point, that can be fed into a standard FTDI232. 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: Amandeep, for the CPH1901 (Oppo A7, right? EDL mode is entered by plugging the cable while having * and # pressed at the same time. 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. So breakpoints are simply placed by replacing instructions with undefined ones which cause the undefined instruction handler, that we hooked, to be executed. 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. 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). By Roee Hay & Noam Hadad. Research & Exploitation framework for Qualcomm EDL Firehose programmers. For details on how to get into EDL, please see our blog post. 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. If emmc flash is used, remove battery, short DAT0 with gnd, connect battery, then remove short. For Oneplus 6T, enter #801# on dialpad, set Engineer Mode and Serial to on and try : Published under MIT license Having a short glimpse at these tags is sufficient to realize that Firehose programmers go way beyond partition flashing. 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. 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. 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. 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. 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. Home EMMC Files All Qualcomm Prog eMMC Firehose Programmer file Download. 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). He loves to publish tutorials on Android IOS Fixing. CAT B35 loader found! 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). A usuable feature of our host script is that it can be fed with a list of basic blocks. Thank you for this!! 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 figure on the left shows a typical boot process of an Android device, wherein the Primary Bootloader triggers the Secondary Bootloader, which in turn boots the complete Android system. Ive managed to fix a bootloop on my Mi A2. To implement breakpoints, we decided to abuse undefined instruction exceptions. Apr 1, 2019 350 106 Innernetz www.noidodroid.com . 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. Digging into the programmers code (Xiaomi Note 5A ugglite aarch32 programmer in this case) shows that its actually an extended SBL of some sort. Some devices have an XBL (eXtensible Bootloader) instead of an SBL. The signed certificates have a root certificate anchored in hardware. Some devices have boot config resistors, if you find the right ones you may enforce booting to sdcard instead of flash. but edl mode is good choice, you should be able to wipe data and frp . We have finally solved the problem by reading through the ARM Architecture Reference Manual, finding that there is an actual instruction that is guaranteed to be permanently undefined (throw undefined instruction exception), regardless of the following word. 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. If you have any questions regarding this Qualcomms special boot mode or face any problems booting your Android device into it, then please let us know. imem is a fast-on-chip memory used for debugging and dma (direct memory access) transactions and is proprietary to qualcomm chipsets. We then present our exploit framework, firehorse, which implements a runtime debugger for firehose programmers (Part 4). After that click on the select programmers path to browse and select the file. 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. We guess that the Boot ROM can only be obtained from the secure state (which anglers programmer runs under). Read our comment policy fully before posting a comment. 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. 62A1E772932EB33E86EE9A141403B78EF2D00F2C6848FE17213B92FCC7FAD1DF, E0B29ACCFF90D46023B449E071E74B1B0503FE704FD0DEFDE7317797601D9F31, 7E8BF70DFAD30A2C410EE91B301FACA9684677656F29F1E287C84360B149823A, B46518743470D2DF8B7DADE1561C87407D6DCE5CC489B88AC981C63078D82782, B674D3DC099E6D1A43D01055AA6089647594B9D455F32EF2238FB619CF67FF5C, 73A038CD54EB5F36C63555FDED82669D6FA98EF7EDA33417615DF481DD98BCFA, 4EF56F77DF83A006F97C5E4AB2385431F573F4F120C1B452D414F01EDA40F637, C073E07C7444C2A1C6E4BFFDBB0D7ABE8E6CB3AB68B2C5F2FA932AC6BBADF360, BE783DC133326E22D06823A335C1AEA0A3E544B4421A407263C9941DB6EA4E0C. (TheyactuallybothhaveadifferentOEMhash,whichprobablymeanstheyaredifferentlysigned,no?). Research & Exploitation framework for Qualcomm EDL Firehose programmers, By Roee Hay (@roeehay) & Noam Hadad, Aleph Reseserch, HCL Technologies. 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. As for aarch64, we also have preliminary support for working with the MMU enabled, by controlling the relevant page table entries. these programmers are often leaked from OEM device repair labs. Analyzing several programmers' binaries quickly reveals that commands are passed through XMLs (over USB). We achieve code execution in the PBL (or more accurately, in a PBL clone), allowing us to defeat the chain of trust, gaining code execution in every part of the bootloader chain, including TrustZone, and the High Level OS (Android) itself. 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. Finally, enter the following command in PowerShell to boot your phone into EDL mode. Knowing the memory-layout of the programmers, and the running exception level, we started peeking around. A working 8110 4G firehose found, should be compatible with any version. 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. This cleared up so much fog and miasma..;-). Research & Exploitation framework for, A couple of years ago, it is easy to unbrick a Xiaomi device through Emergency Download Mode (, Programming & Flashing. When shorted during the boot, these test points basically divert the Primary Bootloader (PBL) to execute EDL mode. My proposed format is the following: - exact filename (in an already uploaded archive) or a URL (if this is a new one). Ok, let's forget about 2720 for now. 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. 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. To verify our empiric-based knowledge, we used our debugger (Part 4) and IDA in order to pinpoint the exact routine in the PBLs we extracted (Part 3), that decides upon the boot mode (normal or EDL). You also wouldnt want your device to turn off while youre flashing the firmware, which could lead to unexpected results. Thats exactly when youd need to use EDL mode. Each of these routines plays an important role in the operation of the PBL. 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. r"C:\Program Files (x86)\Qualcomm\QPST437\bin\fh_loader.exe", r"C:\Program Files (x86)\Qualcomm\QPST437\bin\QSaharaServer.exe". The client is able to at least communicate with my phone. EDL or Emergency DownLoad Mode is a special boot mode in Qualcomm Android devices that allows OEMs to force-flash firmware files. 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). 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. Some encoding was needed too. In aarch32, vector tables are pointed by the VBAR registers (one for each security state). 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. Qualcomm Sahara / Firehose Client (c) B.Kerler 2018-2019. If it is in a bootloop or cannot enter the OS, move to the second method. To start working with a specific device in EDL, you need a programmer. In this part we described our debugging framework, that enabled us to further research the running environment. 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: - HWID (if known) - exact filename (in an already uploaded archive) or a URL (if this is a new one) Requirements to the files: 1. You will need to open the ufs die and short the clk line on boot, some boards have special test points for that. 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.

You must log in or register to reply here. EDL is implemented by the PBL. Modern such programmers implement the Firehose protocol, analyzed next. 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). In this mode, the device identifies itself as Qualcomm HS-USB 9008 through USB. All of these guides make use of Emergency Download Mode (EDL), an alternate boot-mode of the Qualcomm Boot ROM (Primary Bootloader). 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). 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. Gadgets Doctor Provides the best solution to repair any kind of Android or features phones very easily. most programmers use firehose to communicate with a phone in edl mode, which is what the researchers exploited to gain full device control.
