For example, here is the UART TX point for OnePlus 5: On some devices UART is not initialized by the programmers. 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. Do you have Nokia 2720 flip mbn Or Nokia 800 tough mbn? 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. 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. 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. TA-1048, TA-1059 or something else? To implement breakpoints, we decided to abuse undefined instruction exceptions. Why and when would you need to use EDL Mode? 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. You can Download and Use this file to remove Screen lock on Qualcomm Supports Devices, and Bypass FRP Google account on all Qualcomm Devices, Qualcomm Prog eMMC Firehose Programmer file Download, Lava V62 Benco FRP File Download (Bypass Google) by SPD Research Tool Latest Free, DarkRa1n iCloud Bypass Tool iOS 16 iOS 15 Download Free Latest, VNROM FILE Ramdisk Tool Download Windows Latest Version Free, Mina Ramdisk Bypass Tool V1.3 Download Latest Version for MAC Free, GSM Gaster Tool V4.0 Download Latest Passcode, Hello Screen Disable Device, OMH Mi Blu Relock Fixer Tool V1 Download Latest Version Free, iOS Factory Reset Tool V1 Download latest version Free, CICADA iTools V4.1 Download Latest Version Setup Free, Oppo A11s No Auth Loader Firehose File Download Free, Motorola G Stylus 5G EDL Firehose Programmer File Download Free. In the previous part we explained how we gained code execution in the context of the Firehose programmer. 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. Some of them will get our coverage throughout this series of blog posts. There are no posts matching your filters. In fact, thats one of the very common mistakes that users make when their device is bricked. Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. Why not reconstruct the 32-bit page table? You also wouldnt want your device to turn off while youre flashing the firmware, which could lead to unexpected results. Our XML Hunter searches the relevant memory for such pokes, and decodes the data, contained in the supplied attribute. 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. However, thats not the case always. Special care was also needed for Thumb. This method is for when your phone cannot enter the OS but can boot into Fastboot mode (Also sometimes referred to as Bootloader mode). sbl maintains the SBL contextual data, where its first field points to a copy of pbl2sbl_data. A tag already exists with the provided branch name. So follow me on social media: All Qualcomm Prog eMMC Firehose Programmer file Download, Today I will share you all Qualcomm EMMC Filehose Programmer file for Certain Devices, emmc Programs File download for all Qualcomm Chipsets Devices. Did a quick search and found the location of the test points on the Redmi 7A (Click to view the image). 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. Only input your real first name and valid email address if you want your comment to appear. Its main routine is as follows: pbl2sbl_data is the data passed from the PBL to the SBL at the very end of the pbl_jmp_to_sbl function. most programmers use firehose to communicate with a phone in edl mode, which is what the researchers exploited to gain full device control. While the reason of their public availability is unknown, our best guess is that Home EMMC Files All Qualcomm Prog eMMC Firehose Programmer file Download. Comment for robots 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. 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. All of these guides make use of Emergency Download Mode (EDL), an alternate boot-mode of the Qualcomm Boot ROM (Primary Bootloader). HWID: 0x000940e100420050 (MSM_ID:0x000940e1,OEM_ID:0x0042,MODEL_ID:0x0050). 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. As for aarch64, we also have preliminary support for working with the MMU enabled, by controlling the relevant page table entries. ABOOT then verifies the authenticity of the boot or recovery images, loads the Linux kernel and initramfs from the boot or recovery images. Its often named something like prog_*storage. The signed certificates have a root certificate anchored in hardware. Now, boot your phone into Fastboot mode by using the buttons combination. Some OEMs (e.g. P.S. 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). Amandeep, for the CPH1901 (Oppo A7, right? As mentioned above, modern EDL programmers implement the Qualcomm Firehose protocol. Launch the command-line tool in this same folder. It seems the RPM PBL is in the 0xfc000000-0xfc0040000 range, where the MODEM PBL is in the 0xfc004000-0xfc010000 range. 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. 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. 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. Ok, let's forget about 2720 for now. Some times, flashing the wrong file can also potentially corrupt the Android bootloader itself. Save my name, email, and website in this browser for the next time I comment. Before that, we did some preliminary analysis of the MSM8937/MSM8917 PBL, in order to understand its layout in a high-level perspective. Multiple usb fixes. 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. 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 This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. CVE-2017-13174. 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. So, let's collect the knowledge base of the loaders in this thread. This error is often a false-positive and can be ignored as your device will still enter EDL. My proposed format is the following: - exact model name. Apr 1, 2019 350 106 Innernetz www.noidodroid.com . 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? We also read the SCR.NS register (if possible) in order to find if we ran in Secure state. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. 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. Only unencrypted MSM8909-compatible format (the binary contents must start with ELF or "data ddc" signature). You signed in with another tab or window. Phones from Xiaomi and Nokia are more susceptible to this method. We guess that the Boot ROM can only be obtained from the secure state (which anglers programmer runs under). However, the certificate section in it seems to be intact, and this is the most important part in firehose verification. 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. Connect the device to your PC using a USB cable. It looks like we were having a different problem with the Schok Classic, not a fused loader issue. Hold the SHIFT key on the keyboard and right-click on an empty space inside the folder. This special mode of operation is also commonly used by power users to unbrick their devices. Let me start with my own current collection for today -. EDL implements Qualcomm's 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). bricked citrus dead after restart edl authentication firehose . chargers). Extract the downloaded ZIP file to an easily accessible location on your PC. 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. Interestingly, there is a positive trend of blocking these commands in locked Android Bootloaders. Having a short glimpse at these tags is sufficient to realize that Firehose programmers go way beyond partition flashing. You signed in with another tab or window. sahara - ----- HWID: 0x0005f0e100000000 (MSM_ID:0x0005f0e1,OEM_ID:0x0000,MODEL_ID:0x0000) CPU detected: "MSM8996Pro" PK_HASH . Research & Exploitation of Qualcomm EDL Firehose Programmers: From PBL (Boot ROM) Extraction, Research & Analysis to Secure Boot Bypass in Nokia 6. . Therefore, this kind of attack requires the following: Finding the memory location of the execution stack is relatively easy, as this is set in the reset interrupt handler of the programmer: Next, we dumped the stack and searched for saved LR candidates for replacement: We chose 0x0802049b the programmer has a main-loop that waits for incoming XMLs through USB (handle_input from Part 1), so our replaced LR value is the return location to that loop from the XML command parser : Poking the corresponding stack location (0x805cfdc) with an arbitrary address should hijack the execution flow. Tested on our Nexus 6P, trying to read from its PBL physical address (0xFC010000), instantly resulted in a system reboot. A defining property of debuggers is to be able to place breakpoints. For some programmers our flashed data did not remain in memory. After that select the programmer file prog_emmc_firehose_8917_ddrMBN. ALEPH-2017029. Alcatel Onetouch Idol 3. Looking to work with some programmers on getting some development going on this. No, that requires knowledge of the private signature keys. Yes, your device needs to be sufficiently charged to enter EDL mode. Later, the PBL will actually skip the SBL image loading, and go into EDL mode. For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). We obtained and reverse-engineered the PBL of various Qualcomm-based chipsets (, We obtained the RPM & Modem PBLs of Nexus 6P (, We managed to unlock & root various Android Bootloaders, such as Xiaomi Note 5A, using a storage-based attack only. 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. Download the latest Android SDK tools package from. In this part we presented an arbitrary code execution attack against Firehose programmers. 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. For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). The SBL initializes the DDR and loads digitally-signed images such as ABOOT (which implements the fastboot interface) & TrustZone, and again verifies their authenticity. For aarch64 - CurrentEL, for aarch32 - CPSR.M. There are many guides [1,2,3,4,5,6,7] across the Internet for unbricking Qualcomm-based mobile devices. Updated on, P.S. To start working with a specific device in EDL, you need a programmer. My proposed format is the. In addition, rebooting into EDL by software is done by asserting the LSB of the 0x193D100 register (also known as tcsr-boot-misc-detect) 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. EDL is implemented by the PBL. The only thing we need to take care of is copying the original stack and relocating absolute stack address. If emmc flash is used, remove battery, short DAT0 with gnd, connect battery, then remove short. When shorted during the boot, these test points basically divert the Primary Bootloader (PBL) to execute EDL mode. Deeper down the rabbit hole, analyzing firehose_main and its descendants sheds light on all of the Firehose-accepted XML tags. Credits & Activations. For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). In order to tackle that, we abused the Firehose protocol in the following ways: Egg Hunting. The first part presents some internals of the PBL, EDL, Qualcomm Sahara and programmers, focusing on Firehose. Thread starter sloshnmosh; Start date Jun 12, 2018; Forums. So can you configure a firehose for nokia 2720/800? My proposed format is the following: - exact filename (in an already uploaded archive) or a URL (if this is a new one). However, we soon realized that there were many corner cases with that approach, such as setting breakpoints on instructions that cross their basic block boundary that could cause invalid breakpoints to be hit. 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. 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. Onetouch Idol 3 Android Development . 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. 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. In aarch32, vector tables are pointed by the VBAR registers (one for each security state). 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.
