";s:4:"text";s:15833:"If emmc flash is used, remove battery, short DAT0 with gnd, connect battery, then remove short. On Linux or macOS: Launch the Terminal and change its directory to the platform-tools folder using the cd command. 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. For details on how to get into EDL, please see our blog post. 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. or from here, Make a subdirectory "newstuff", copy your edl loaders to this subdirectory, or sniff existing edl tools using Totalphase Beagle 480, set filter to filter({'inputs': False, 'usb3': False, 'chirps': False, 'dev': 26, 'usb2resets': False, 'sofs': False, 'ep': 1}), export to binary file as "sniffeddata.bin" and then use beagle_to_loader sniffeddata.bin. - HWID (if known) - exact filename (in an already uploaded archive) or a URL (if this is a new one) Requirements to the files: 1. Does this mean, the firehose should work? In this post, you will learn what EDL mode is, and why and when youd need to use it. While the reason of their public availability is unknown, our best guess is that There are no posts matching your filters. There are several ways to coerce that device into EDL. You also wouldnt want your device to turn off while youre flashing the firmware, which could lead to unexpected results. Interestingly, in the actual SBL of ugglite, this series of initialization callbacks looks as follows: Therefore, they only differ in the firehose_main callback! Luckily enough (otherwise, where is the fun in that? https://alephsecurity.com/2018/01/22/qualcomm-edl-1/, https://github.com/alephsecurity/firehorse, [TOOL] Sahara & Firehose Test (Alcatel Flasher oncoming ), [ROM/FIRMWARE][6045X] Android 6.0 Marshmallow for Alcatel Onetouch Idol 3 5.5, [6039] - ***GUIDE*** - How to return the fastboot commands on already upgraded device, [ROM] 6045Y-DCZ - 6.0.1 stock, root, debloat - 2.2 (2016-08-09), [ROM][6045X][7.1.2][Resurrection Remix][5.8.5][Nougat][UNOFFICIAL][FINAL] IDOL 3 5.5, How to fix - cannot boot into system after /vendor changed file system (ext2, ext4), Junsun V1 Pro MTK8259 4GB + 64GB Android 10 headunit, Junsun V1 Pro (MTK8259/MTK8257) - firmware. firehorse. No, that requires knowledge of the private signature keys. Some of them will get our coverage throughout this series of blog posts. Alcatel Onetouch Idol 3. Since we gained code execution in either EL3 or EL1, we can easily catch ARM exceptions. 5 Butunfortunatelydoesn'tseemtowork. For some programmers our flashed data did not remain in memory. Of course, the credits go to the respective source. You must log in or register to reply here. I know that some of them must work at least for one 8110 version. Some SBLs may also reboot into EDL if they fail to verify that images they are in charge of loading. This feature is used by our Nokia 6 exploit, since we need to relocate the debugger during the SBL to ABOOT transition. My proposed format is the. MSM-based devices contain a special mode of operation - Emergency Download Mode (EDL). It contains the init binary, the first userspace process. Do you have Nokia 2720 flip mbn Or Nokia 800 tough mbn? imem is a fast-on-chip memory used for debugging and dma (direct memory access) transactions and is proprietary to qualcomm chipsets.

"/>. The extracted platform-tools folder will contain ADB and other binaries youd need. 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. EDL or Emergency DownLoad Mode is a special boot mode in Qualcomm Android devices that allows OEMs to force-flash firmware files. sbl maintains the SBL contextual data, where its first field points to a copy of pbl2sbl_data. When such an exception occurs, a relevant handler, located at an offset from the vector base address, is called. Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. We must be at any moment prepared for organized resistance against the pressure from anyone trying to take away what's ours. 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. To do this: On Windows: Open the platform-tools folder. Ok, let's forget about 2720 for now. It looks like we were having a different problem with the Schok Classic, not a fused loader issue. Nokia 6/5 and old Xiaomi SBLs), and reboot into EDL if these pins are shortened. 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). We're now entering a phase where fundamental things have to be understood. Just plug in your device to the wall charger for at least 30-40 minutes so that it gets sufficiently charged. HWID: 0x009600e100000000 (MSM_ID:0x009600e1,OEM_ID:0x0000,MODEL_ID:0x0000), PK_HASH: 0xcc3153a80293939b90d02d3bf8b23e0292e452fef662c74998421adad42a380f. 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. MSM (Qualcomms SoC)-based devices, contain a special mode of operation - Emergency Download Mode (EDL). In order to tackle that, we abused the Firehose protocol in the following ways: Egg Hunting. So, the file is indeed correct but it's deliberately corrupted. P.S. For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). This method is for when your phone cannot enter the OS but can boot into Fastboot mode (Also sometimes referred to as Bootloader mode). The client is able to at least communicate with my phone. 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. Additional license limitations: No use in commercial products without prior permit. Receive the freshest Android & development news right in your inbox! Modern such programmers implement the Firehose protocol, analyzed next. Later, the PBL will actually skip the SBL image loading, and go into EDL mode. Nokia 800 Tough seems to have the same HWID. Therefore, the address of the next gadget (0x8008D38) should be written to ORIGINAL_SP + 4 + 0x118 + 20 (R4-R8). 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. 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. The first part presents some internals of the PBL, EDL, Qualcomm Sahara and programmers, focusing on Firehose. 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. 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). This isn't strictly speaking a Bananahackers question (because it's about Android phones), but this is where I learned about EDL mode. After that click on the select programmers path to browse and select the file. Peeking at this address gives the following: Our research tool, firehorse can then walk through the page tables: APX=0, AP=0x3, NX=0x0 means a written and executable (WX) page. You signed in with another tab or window. EDL itself is a part of the Primary Bootloader (PBL) on Qualcomm Devices. For example, if the folder in the Documents directory, the command should be: Now, enable USB debugging on your Android device using the instructions. In the previous part we explained how we gained code execution in the context of the Firehose programmer. Could you share the procedure for using CM2QLM (including the software if possible) with file loader for Nokia 8110 4G TA-1059 as my device is bricked and can't enter recovery mode, but edl mode is available but showing the following error kali@kali:~/Desktop/edl-master$ python3 edl.py -loader 0x000940e100420050.mbn. After I learned about EDL mode on the Cingular Flip 2, I discovered that it was useful on Android flip phones too. We then read the leaked register using the peek primitive: Hence TTBR0 = 0x200000! To know about your device-specific test points, you would need to check up on online communities like XDA. Are you sure you want to create this branch? 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. 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. So breakpoints are simply placed by replacing instructions with undefined ones which cause the undefined instruction handler, that we hooked, to be executed. Some devices have an XBL (eXtensible Bootloader) instead of an SBL. As one can see, the relevant tag that instructs the programmer to flash a new image is program. The first part presents some internals of the PBL, EDL, Qualcomm Sahara and programmers, focusing on Firehose. but edl mode is good choice, you should be able to wipe data and frp . 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. 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. For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). Exploiting Qualcomm EDL Programmers (4): Runtime Debugger. Only unencrypted MSM8909-compatible format (the binary contents must start with ELF or "data ddc" signature). the Egg). All of our extracted PBLs were 32-bit (run in aarch32), where the SBLs were either aarch32 or aarch64, in which the PBL is in charge of the transition. Apr 1, 2019 350 106 Innernetz www.noidodroid.com . A natural continuation of this research is gaining arbitrary code execution in the context of the programmer itself. (Later we discovered that this was not necessary because we also statically found that address in the PBL & Programmer binaries.) Before we do so, we need to somehow get output from the device. 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. After that select the programmer file prog_emmc_firehose_8917_ddrMBN. 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). Research & Exploitation framework for Qualcomm EDL Firehose programmers. By dumping that range using firehorse, we got the following results: We certainly have something here! Next, set the CROSS_COMPILE_32 and CROSS_COMPILE_64 enviroment vars as follows: Then call make and the payload for your specific device will be built. Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. So, let's collect the knowledge base of the loaders in this thread. Analyzing several programmers binaries quickly reveals that commands are passed through XMLs (over USB). Hi, We describe the Qualcomm EDL (Firehose) and Sahara Protocols. Triedonboth,8110&2720. 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. Research & Exploitation framework for Qualcomm EDL Firehose programmers, By Roee Hay (@roeehay) & Noam Hadad, Aleph Reseserch, HCL Technologies. Inofficial Qualcomm Firehose / Sahara / Streaming / Diag Tools :), User: user, Password:user (based on Ubuntu 22.04 LTS), You should get these automatically if you do a git submodule update --init --recursive 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. 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. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Now, boot your phone into Fastboot mode by using the buttons combination. (TheyactuallybothhaveadifferentOEMhash,whichprobablymeanstheyaredifferentlysigned,no?). Launch the command-line tool in this same folder. Qualcomm Sahara / Firehose Client (c) B.Kerler 2018-2019. 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. We then continued by exploring storage-based attacks. Connect the device to your PC using a USB cable. 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. A domain set to manager instructs the MMU to always allow access (i.e. As for aarch64, we also have preliminary support for working with the MMU enabled, by controlling the relevant page table entries. 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). And thus, there would be no chance of flashing the firmware to revive/unbrick the device. r"C:\Program Files (x86)\Qualcomm\QPST437\bin\fh_loader.exe", r"C:\Program Files (x86)\Qualcomm\QPST437\bin\QSaharaServer.exe". Thats exactly when youd need to use EDL mode. As mentioned above, modern EDL programmers implement the Qualcomm Firehose protocol. In addition, OnePlus 5s programmers runs in EL1, so we used SCTLR_EL1 instead of the EL3 counterpart. Sylvain, if you know HWID of JioPhone 2, could you pls post it as well? Gadgets Doctor Provides the best solution to repair any kind of Android or features phones very easily. For Nokia 6, we used the following ROP chain: GADGET 1: We increase the stack with 0x118 bytes.
