qualcomm edl firehose programmers

By dumping that range using firehorse, we got the following results: We certainly have something here! This gadget will return to GADGET 2. Hold the SHIFT key on the keyboard and right-click on an empty space inside the folder. 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. This isn't strictly speaking a Bananahackers question (because it's about Android phones), but this is where I learned about EDL mode. Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. Now, boot your phone into Fastboot mode by using the buttons combination. Onetouch Idol 3 Android Development . If it is in a bootloop or cannot enter the OS, move to the second method. A natural continuation of this research is gaining arbitrary code execution in the context of the programmer itself. 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). This error is often a false-positive and can be ignored as your device will still enter EDL. Could anyone please test the attached firehose on 8110 4G (TA-1059 or TA-1048) or 2720 Flip? In the previous part we explained how we gained code execution in the context of the Firehose programmer. initramfs is a cpio (gzipped) archive that gets loaded into rootfs (a RAM filesystem mounted at /) during the Linux kernel initialization. We reported this kind of exposure to some vendors, including OnePlus (CVE-2017-5947) and Google (Nexus 6/6P devices) - CVE-2017-13174. 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. 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. The programmer implements the Firehose protocol which allows the host PC to send commands to write into the onboard storage (eMMC, UFS). We then read the leaked register using the peek primitive: Hence TTBR0 = 0x200000! 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. 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. Deeper down the rabbit hole, analyzing firehose_main and its descendants sheds light on all of the Firehose-accepted XML tags. In the next part we display the cherry on top a complete Secure Boot exploit against Nokia 6 MSM8937. The debuggers base address is computed in runtime (init_set_fh_entry()), and any absolute address is calculated as an offset from that base. However,theOEMhashisexactlythesameastheTA-1059. 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. 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. 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. Please empty this comment field to prove you're human. Some times, flashing the wrong file can also potentially corrupt the Android bootloader itself. I must to tell you, I never, ever slow enough to comment on any site .but I was compelled to stop and say THANK YOU THANK YOU THANK . In this mode, the device identifies itself as Qualcomm HS-USB 9008 through USB. 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. First, the PBL will mark the flash as uninitialized, by setting pbl->flash_struct->initialized = 0xA. 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. So, I have an idea how we could deal with this, and will check this idea tomorrow. 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. Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. ABOOT then verifies the authenticity of the boot or recovery images, loads the Linux kernel and initramfs from the boot or recovery images. If emmc flash is used, remove battery, short DAT0 with gnd, connect battery, then remove short. 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. Let me start with my own current collection for today -. 2021. In this part we presented an arbitrary code execution attack against Firehose programmers. We describe the Qualcomm EDL (Firehose) and Sahara Protocols. In the previous part we explained how we gained code execution in the context of the Firehose programmer. 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. 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. Read our comment policy fully before posting a comment. Some OEMs (e.g. 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). In addition, rebooting into EDL by software is done by asserting the LSB of the 0x193D100 register (also known as tcsr-boot-misc-detect) In the Nokia 6 programmer (and maybe others as well), the result of the partition flashing process remains in the device memory, even after its complete. Improved streaming stuff, Qualcomm Sahara / Firehose Attack Client / Diag Tools. A domain set to manager instructs the MMU to always allow access (i.e. This special mode of operation is also commonly used by power users to unbrick their devices. This method has a small price to pay. Research & Exploitation framework for Qualcomm EDL Firehose programmers, By Roee Hay (@roeehay) & Noam Hadad, Aleph Reseserch, HCL Technologies. MSM (Qualcomms SoC)-based devices, contain a special mode of operation - Emergency Download Mode (EDL). We showed that such code, may get executed with the highest possible privileges in ARM processors, and can dump Boot ROMs of various such SoCs. The init function is in charge of the following: This struct contains the following fields: (The shown symbols are of course our own estimates.). It's already in the above archive. 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. most programmers use firehose to communicate with a phone in edl mode, which is what the researchers exploited to gain full device control. ignore the access righs completely). $ ./edl.py Qualcomm Sahara / Firehose Client V3.3 (c) B.Kerler 2018-2021. main - Trying with no loader given . In this mode, the device identifies itself as Qualcomm HS-USB 9008 through USB. you can check other tutorialshere to help. - HWID (if known) - exact filename (in an already uploaded archive) or a URL (if this is a new one) Requirements to the files: 1. I have the firehose/programmer for the LG V60 ThinQ. 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. therefore we can simply load arbitrary code in such pages, and force the execution towards that code for Nokia 6, ROP was not needed after all! Sorry, couldn't talk to Sahara, please reboot the device ! Knowing the memory-layout of the programmers, and the running exception level, we started peeking around. To have a better understanding, please take a look at the figures below. In this part we extend the capabilities of firehorse even further, making it . This method is for when your phone cannot enter the OS but can boot into Fastboot mode (Also sometimes referred to as Bootloader mode). There are several ways to coerce that device into EDL. 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. Apr 1, 2019 350 106 Innernetz www.noidodroid.com . I have made a working package for Nokia 8110 for flashing with cm2qlm module. P.S. 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. 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. Since the PBL is a ROM resident, EDL cannot be corrupted by software. Additional license limitations: No use in commercial products without prior permit. This feature is used by our Nokia 6 exploit, since we need to relocate the debugger during the SBL to ABOOT transition. Some devices have an XBL (eXtensible Bootloader) instead of an SBL. Interestingly, there is a positive trend of blocking these commands in locked Android Bootloaders. chargers). sbl maintains the SBL contextual data, where its first field points to a copy of pbl2sbl_data. Berbagai Masalah Vivo Y51L. And thus, there would be no chance of flashing the firmware to revive/unbrick the device.

So, thanks to anonymous Israeli volunteers, we now have a working firehose loader for all Nokia 2720 Flip variants. 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.

"/>. For a better experience, please enable JavaScript in your browser before proceeding. (, 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. please provide me with the package including the procedure please I need to unbrick my Nokia 8110-4g. Catching breakpoints is only one side of the coin, the other recovery and execution of the original instruction. 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. 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. Its often named something like prog_*storage. It seems like EDL mode is only available for a split second and then turn off. 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). There are many guides [1,2,3,4,5,6,7] across the Internet for unbricking Qualcomm-based mobile devices. EDL or Emergency DownLoad Mode is a special boot mode in Qualcomm Android devices that allows OEMs to force-flash firmware files. (Nexus 6P required root with access to the sysfs context, see our vulnerability report for more details). During this process, EDL implements the Firehose/Sahara protocol and acts as a Secondary Bootloader to accept commands for flashing. 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: We must be at any moment prepared for organized resistance against the pressure from anyone trying to take away what's ours.
