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. most programmers use firehose to communicate with a phone in edl mode, which is what the researchers exploited to gain full device control. The signed certificates have a root certificate anchored in hardware. In this mode, the device identifies itself as Qualcomm HS-USB 9008 through USB. P.S. Why and when would you need to use EDL Mode? A tag already exists with the provided branch name. When such an exception occurs, a relevant handler, located at an offset from the vector base address, is called. Today I will share you all Qualcomm EMMC Filehose Programmer file for Certain Devices.. emmc Programs File download for all Qualcomm Chipsets Devices. 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. Luckily enough (otherwise, where is the fun in that? please provide me with the package including the procedure please I need to unbrick my Nokia 8110-4g. Multiple usb fixes. Some of these powerful capabilities are covered extensively throughout the next parts. In the previous part we explained how we gained code execution in the context of the Firehose programmer. 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. I have made a working package for Nokia 8110 for flashing with cm2qlm module. 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. I have an oppo made android mobile phone model no CPH1901 and want to put it into EDL mode try above mentioned methods using ADB but get not responding results. 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). Extract the downloaded ZIP file to an easily accessible location on your PC. 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). 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. It can be found online fairly easily though. Apr 1, 2019 350 106 Innernetz www.noidodroid.com . In the case of Qualcomm , these programmers are referred to as " firehose >" binaries. HWID: 0x009600e100000000 (MSM_ID:0x009600e1,OEM_ID:0x0000,MODEL_ID:0x0000), PK_HASH: 0xcc3153a80293939b90d02d3bf8b23e0292e452fef662c74998421adad42a380f. Deeper down the rabbit hole, analyzing firehose_main and its descendants sheds light on all of the Firehose-accepted XML tags. Only input your real first name and valid email address if you want your comment to appear. My proposed format is the following: - exact filename (in an already uploaded archive) or a URL (if this is a new one). EDL itself is a part of the Primary Bootloader (PBL) on Qualcomm Devices. - HWID (if known) - exact filename (in an already uploaded archive) or a URL (if this is a new one) Requirements to the files: 1. 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). firehorse. Berbagai Masalah Vivo Y51L. This method is for when your phone cannot enter the OS but can boot into Fastboot mode (Also sometimes referred to as Bootloader mode). Home EMMC Files All Qualcomm Prog eMMC Firehose Programmer file Download. Our XML Hunter searches the relevant memory for such pokes, and decodes the data, contained in the supplied attribute. I can't get it running, but I'm not sure, why. And thus, there would be no chance of flashing the firmware to revive/unbrick the device. ), 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. Some of them will get our coverage throughout this series of blog posts. 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. Having arbitrary code execution, we could begin researching the programmers, this time in runtime. And the only way to reliably resist is to spread the information and the tools for low-level hardware access they can't easily change on their whim. If you install python from microsoft store, "python setup.py install" will fail, but that step isn't required. please tell me the solution. In this part we extend the capabilities of firehorse even further, making it . 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. 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). This cleared up so much fog and miasma..;-). Digging into the programmers code (Xiaomi Note 5A ugglite aarch32 programmer in this case) shows that its actually an extended SBL of some sort. However,theOEMhashisexactlythesameastheTA-1059. If youre familiar with flashing firmware or custom binaries (like TWRP, root, etc), youd know that it is required to boot the Android device into specific boot modes like Fastboot or Download Modes. 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. sahara - ----- HWID: 0x0005f0e100000000 (MSM_ID:0x0005f0e1,OEM_ID:0x0000,MODEL_ID:0x0000) CPU detected: "MSM8996Pro" PK_HASH . 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). 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. because virtually any firehose file will work there. Since the PBL is a ROM resident, EDL cannot be corrupted by software. We end with a A usuable feature of our host script is that it can be fed with a list of basic blocks. Special care was also needed for Thumb. To exploit that, we first flash our data on some bogus / backup partition, and then upload a small, Egg Hunter, that searches the relevant memory for our previously uploaded data (i.e. Your device needs to have a usb pid of 0x9008 in order to make the edl tool work. Thats exactly when youd need to use EDL mode. The debugger receives the list of breakpoints, patches, and pages to be copied (more on this in the next part) to perform from the host script, by abusing the Firehose protocol (either with the poke primitive or more rapidly using a functionality we developed that is described next). Its 16-bit encoding is XXDE. In the case of the Firehose programmer, however, these features are built-in! It seems like EDL mode is only available for a split second and then turn off. For example, on OnePlus 5: Now that we can conveniently receive output from the device, were finally ready for our runtime research. (, 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. 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. 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. Mar 22, 2021 View. 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. Ok, let's forget about 2720 for now. 2021. chargers). 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. Each of these routines plays an important role in the operation of the PBL. 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. Finding the address of the execution stack. There are many guides [1,2,3,4,5,6,7] across the Internet for unbricking Qualcomm-based mobile devices. By dumping that range using firehorse, we got the following results: We certainly have something here! Thread starter sloshnmosh; Start date Jun 12, 2018; Forums. In order to further understand the memory layout of our devices, we dumped and parsed their page tables. It contains the init binary, the first userspace process. r"C:\Program Files (x86)\Qualcomm\QPST437\bin\fh_loader.exe", r"C:\Program Files (x86)\Qualcomm\QPST437\bin\QSaharaServer.exe". Unfortunately, aarch32 lacks single-stepping (even in ARMv8). You must log in or register to reply here. Executing this chain, we managed to leak the TTBR0 register into a controlled memory address without crashing the device (by reconstructing the stack and returning to the original caller). very, very useful! You are using an out of date browser. Before we start, we need to configure some stuff, edit the constants.py file in the host directory: This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. 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). MSM (Qualcomm's SoC)-based devices, contain a special mode of operation - Emergency Download Mode (EDL). For example, for Nexus 6P (MSM8994) we used the following chain in order to disable the MMU Similarly to Nokia 6, we found the stack base address (0xFEC04000), dumped it, and chose a stored LR target (0xFEC03F88). 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. Part 3, Part 4 & Part 5 are dedicated for the main focus of our research memory based attacks. I'm not sure if I'm using the right file, but I can see quite a bit of raw data being exchanged by using the client's --debug option. I retrieved the file from another device which reports exactly the same HWID and PK_HASH as yours and I found this group by complete accident. You also wouldnt want your device to turn off while youre flashing the firmware, which could lead to unexpected results. The client is able to at least communicate with my phone. 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: Please take a look at the image posted on this website, it illustrates the correct EDL test points for the Oppo A7. Seems like CAT is using generic HWID for 8909 devices We got very lucky with this. It looks like we were having a different problem with the Schok Classic, not a fused loader issue. We presented our research framework, firehorse, and showed how we extracted the PBL of various SoCs. It may not display this or other websites correctly. 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, the PBL will actually skip the SBL image loading, and go into EDL mode. The following info was from the device that works with the programmer I attached, HWID: 0x009600e100000000 (MSM_ID:0x009600e1,OEM_ID:0x0000,MODEL_ID:0x0000), PK_HASH: 0xcc3153a80293939b90d02d3bf8b23e0292e452fef662c74998421adad42a380f, prog_emmc_firehose_8909_ddr[d96ada9cc47bec34c3af6a3b54d6a73466660dcb].mbn, Andy, thanks a lot for figuring out the non-standard XML response for Nokias, merged your changes back into the, Also, if you didn't notice, we also already have the 800 Tough firehose in our, https://cloud.disroot.org/s/HzxB6YM2wRFPpWT/download, http://forum.gsmhosting.com/vbb/f296/nokia-8110-4g-full-support-infinity-qlm-1-16-a-2574130/, http://dl1.infinity-box.com/00/pub.php?dir=software/, http://edl.bananahackers.net/loaders/0x000940e100420050.mbn, https://groups.google.com/d/topic/bananahackers/T2RmKKGvGNI/unsubscribe, https://groups.google.com/d/msgid/bananahackers/3c9cf64a-710b-4f36-9090-7a00bded4a99n%40googlegroups.com. So, let's collect the knowledge base of the loaders in this thread. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Ive managed to fix a bootloop on my Mi A2. Research & Exploitation framework for, A couple of years ago, it is easy to unbrick a Xiaomi device through Emergency Download Mode (, Programming & Flashing. 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. To start working with a specific device in EDL, you need a programmer. the last gadget will return to the original caller, and the device will keep processing Firehose commands. There are no posts matching your filters. Qualcomm Firehose Programmer file Collection: Download Prog_firehose files for All Qualcomm SoC. For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). 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. 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. Additional license limitations: No use in commercial products without prior permit. Now, boot your phone into Fastboot mode by using the buttons combination. The routine sets the bootmode field in the PBL context. CAT B35 loader found! To do so, we devised a ROP-based exploit, in order to leak the TTBR0 register, which holds the base address of the page table.

"/>. January 22, 2018 * QPSIIR-909. 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) Google has patched CVE-2017-13174 in the December 2017 Security Bullet-in. For a better experience, please enable JavaScript in your browser before proceeding. 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. We then present our exploit framework, firehorse, which implements a runtime debugger for firehose programmers (Part 4). So, the file is indeed correct but it's deliberately corrupted. Individual loaders must have .mbn or .bin extension, archives should be preferably zip or 7z, no rar; 3. the Egg). Thats it! MSM-based devices contain a special mode of operation - Emergency Download Mode (EDL). Tested on our Nexus 6P, trying to read from its PBL physical address (0xFC010000), instantly resulted in a system reboot. Its powered by an octa-core Qualcomm Snapdragon 460 chipset paired with Adreno 610 graphics 3GB RAM 64GB onboard storage a dedicated MicroSD card slot. The following example shows the UART output of our debugger running in the context of the OnePlus 5 programmer: On Xiaomi 5As aarch32 programmer the debugger prints the following: A significant feature of our debugger is that it is fully relocatable, and its memory layout is configurable depending on the target. 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? these programmers are often leaked from OEM device repair labs. Since we gained code execution in either EL3 or EL1, we can easily catch ARM exceptions. Analyzing several programmers' binaries quickly reveals that commands are passed through XMLs (over USB). 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. bricked citrus dead after restart edl authentication firehose . He loves to publish tutorials on Android IOS Fixing. Modern such programmers implement the Firehose protocol. Some encoding was needed too. Some devices have an XBL (eXtensible Bootloader) instead of an SBL. As mentioned above, modern EDL programmers implement the Qualcomm Firehose protocol. Xiaomi) also publish them on their official forums. 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. My proposed format is the. Rebooting into EDL can also happen from the Platform OS itself, if implemented, and if adb access is allowed, by running adb reboot edl. 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. In order to tackle that, we abused the Firehose protocol in the following ways: Egg Hunting. So, let's collect the knowledge base of the loaders in this thread. We describe the Qualcomm EDL (Firehose) and Sahara Protocols. Later, our UART output can be fed into IDA, using another IDA Python script, to mark the execution path. Onetouch Idol 3 Android Development . Yes, your device needs to be sufficiently charged to enter EDL mode. This error is often a false-positive and can be ignored as your device will still enter EDL. After running our chain, we could upload to and execute our payload at any writable memory location. We believe other PBLs are not that different. We're now entering a phase where fundamental things have to be understood. MSM (Qualcomms SoC)-based devices, contain a special mode of operation - Emergency Download Mode (EDL). The programmer implements the Firehose protocol which allows the host PC to send commands to write into the onboard storage (eMMC, UFS). 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. Triedonboth,8110&2720. In this post, you will learn what EDL mode is, and why and when youd need to use it. 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. Luckily for us, it turns out that most Android devices expose a UART point, that can be fed into a standard FTDI232. Exploiting Qualcomm EDL Programmers (4): Runtime Debugger. We then read the leaked register using the peek primitive: Hence TTBR0 = 0x200000! Hi, Further updates on this thread will also be reflected at the special. Updated on, P.S. To gain access to EDL mode on your phone, follow the instructions below. We also encountered SBLs that test the USB D+/GND pins upon boot (e.g. I'm using the Qualcomm Sahara/Firehose client on Linux.
