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. 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: In this part we described our debugging framework, that enabled us to further research the running environment. Gadgets Doctor Provides the best solution to repair any kind of Android or features phones very easily. To know about your device-specific test points, you would need to check up on online communities like XDA. Could anyone please test the attached firehose on 8110 4G (TA-1059 or TA-1048) or 2720 Flip? After running our chain, we could upload to and execute our payload at any writable memory location. On Linux or macOS: Launch the Terminal and change its directory to the platform-tools folder using the cd command. 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. At this stage of the research, we did not have much understanding of the memory layout of the programmers, and due to the fact that poking an unmapped arbitrary address resulted in a crash (either infinite loop or a reboot), we had to discover a more intelligent way in order to deduce the such memory layout of the programmer. Analyzing several Firehose programmers binaries quickly reveals that this is an XML over USB protocol. Moreover, implementing support for adjacent breakpoints was difficult. 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. In this mode, the device identifies itself as Qualcomm HS-USB 9008 through USB. Some of them will get our coverage throughout this series of blog posts. JavaScript is disabled. There are no posts matching your filters. The programmer implements the Firehose protocol which allows the host PC to send commands to write into the onboard storage (eMMC, UFS). We must be at any moment prepared for organized resistance against the pressure from anyone trying to take away what's ours. 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) If emmc flash is used, remove battery, short DAT0 with gnd, connect battery, then remove short. Must be easily downloadable (no turbobits/dfiles and other adware), preferably a direct link; 2. Analyzing several programmers' binaries quickly reveals that commands are passed through XMLs (over USB). Before that, we did some preliminary analysis of the MSM8937/MSM8917 PBL, in order to understand its layout in a high-level perspective. 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. Please empty this comment field to prove you're human. 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. For Oneplus 6T, enter #801# on dialpad, set Engineer Mode and Serial to on and try : Published under MIT license 11. Skipping the first 8 entries, that worked pretty well: Interestingly, the second level page table of 0xfc000000 is as follows: There is a noticeable hole from 0xfc000000 to 0xfc010000 (where the PBL begins), which does not exist in the 64-bit counterpart. Thats it! So, let's collect the knowledge base of the loaders in this thread. If your Qualcomm device is already in a bricked state and shows nothing but a black screen, then chances are that it is already in Emergency Download Mode. main - Waiting for the device main - Device detected :) main - Mode detected: sahara Device is in EDL mode .. continuing. In this post, you will learn what EDL mode is, and why and when youd need to use it. 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. This method has a small price to pay. So, as long as your Android device could boot into the EDL mode, theres a chance you can flash the firmware file to recover and unbrick it. We guess that the Boot ROM can only be obtained from the secure state (which anglers programmer runs under). 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. A domain set to manager instructs the MMU to always allow access (i.e. 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. Your device needs to have a usb pid of 0x9008 in order to make the edl tool work. sbl maintains the SBL contextual data, where its first field points to a copy of pbl2sbl_data. To gain access to EDL mode on your phone, follow the instructions below. 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. When such an exception occurs, a relevant handler, located at an offset from the vector base address, is called. Home EMMC Files All Qualcomm Prog eMMC Firehose Programmer file Download. Amandeep, for the CPH1901 (Oppo A7, right? (, 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. As for remediation, vendors with leaked programmers should use Qualcomms Anti-Rollback mechanism, if applicable, in order to prevent them from being loaded by the Boot ROM (PBL), The problem is caused by customizations from OEMsOur Boot ROM supports anti-rollback mechanism for the firehose image., Exploiting Qualcomm EDL Programmers (5): Breaking Nokia 6's Secure Boot, Exploiting Qualcomm EDL Programmers (4): Runtime Debugger, Exploiting Qualcomm EDL Programmers (3): Memory-based Attacks & PBL Extraction, Exploiting Qualcomm EDL Programmers (2): Storage-based Attacks & Rooting, Exploiting Qualcomm EDL Programmers (1): Gaining Access & PBL Internals, Obtain and reverse-engineer the PBL of various Qualcomm-based chipsets (, Obtain the RPM & Modem PBLs of Nexus 6P (, Manifest an end-to-end attack against our Nokia 6 device running Snapdragon 425 (. Today I will share you all Qualcomm EMMC Filehose Programmer file for Certain Devices.. emmc Programs File download for all Qualcomm Chipsets Devices. When in this mode, the device identifies itself as Qualcomm HS-USB QDLoader 9008 over a USB connection. This special mode of operation is also commonly used by power users to unbrick their devices. 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. Knowing the memory-layout of the programmers, and the running exception level, we started peeking around. However, the certificate section in it seems to be intact, and this is the most important part in firehose verification. However,theOEMhashisexactlythesameastheTA-1059. To defeat that, we devised a ROP chain that disables the MMU itself! 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. In this mode, the device identifies itself as Qualcomm HS-USB 9008 through USB. 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). imem is a fast-on-chip memory used for debugging and dma (direct memory access) transactions and is proprietary to qualcomm chipsets. MSM-based devices contain a special mode of operation - Emergency Download Mode (EDL). 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. 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. If a ufs flash is used, things are very much more complicated. Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. And thus, there would be no chance of flashing the firmware to revive/unbrick the device. EDL or Emergency DownLoad Mode is a special boot mode in Qualcomm Android devices that allows OEMs to force-flash firmware files. So can you configure a firehose for nokia 2720/800? We presented our research framework, firehorse, and showed how we extracted the PBL of various SoCs. CAT B35 loader found! No, that requires knowledge of the private signature keys. In aarch32, vector tables are pointed by the VBAR registers (one for each security state). Doing so will allow us to research the programmer in runtime. You must log in or register to reply here. noidodroid Senior Member. Having arbitrary code execution, we could begin researching the programmers, this time in runtime. EDL is implemented by the PBL. Ive managed to fix a bootloop on my Mi A2. In this mode, the device identifies itself as Qualcomm HS-USB 9008 through USB. I dont think the mother board is receiving power as the battery is dead. We presented our research framework, firehorse, and showed how we extracted the PBL of various SoCs. CVE-2017 . One significant problem we encountered during the development of the debugger is that upload rate over poke is extremely slow. the last gadget will return to the original caller, and the device will keep processing Firehose commands. I have made a working package for Nokia 8110 for flashing with cm2qlm module. Meaninganyworkingloader,willworkonbothofthem(andhopefullyfortheotheronesaswell). Some of these powerful capabilities are covered extensively throughout the next parts. Credits & Activations.

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. During this process, EDL implements the Firehose/Sahara protocol and acts as a Secondary Bootloader to accept commands for flashing. XDA Developers was founded by developers, for developers. Just plug in your device to the wall charger for at least 30-40 minutes so that it gets sufficiently charged.

The SBL initializes the DDR and loads digitally-signed images such as ABOOT (which implements the fastboot interface) & TrustZone, and again verifies their authenticity. Qualcomm Firehose Programmer file Collection: Download Prog_firehose files for All Qualcomm SoC. 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. This feature is used by our Nokia 6 exploit, since we need to relocate the debugger during the SBL to ABOOT transition. ), Oneplus 3T/5/6T/7T/8/8t/9/Nord CE/N10/N100 (Read-Only), BQ X, BQ X5, BQ X2, Gigaset ME Pure, ZTE MF210, ZTE MF920V, Sierra Wireless EM7455, Netgear MR1100-10EUS, Netgear MR5100. Save my name, email, and website in this browser for the next time I comment. For most devices the relevant UART points have already been documented online by fellow researchers/engineerings. The source is pretty much verified. Rebooting into EDL can also happen from the Platform OS itself, if implemented, and if adb access is allowed, by running adb reboot edl. An abstract overview of the boot process of Qualcomm MSM devices is as follows: The PBL kicks-in from ROM after the device is powered-on. Download the latest Android SDK tools package from. 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: Our next goal was to be able to use these primitives in order to execute code within the programmer itself. Tested on our Nexus 6P, trying to read from its PBL physical address (0xFC010000), instantly resulted in a system reboot. A tag already exists with the provided branch name. (Nexus 6P required root with access to the sysfs context, see our vulnerability report for more details). Nokia 800 Tough seems to have the same HWID.

"/>. If you install python from microsoft store, "python setup.py install" will fail, but that step isn't required. MSM (Qualcomms SoC)-based devices, contain a special mode of operation - Emergency Download Mode (EDL). The signed certificates have a root certificate anchored in hardware. Therefore, the address of the next gadget (0x8008D38) should be written to ORIGINAL_SP + 4 + 0x118 + 20 (R4-R8). 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. Hi, The figure on the right shows the boot process when EDL mode is executed. Do you have Nokia 2720 flip mbn Or Nokia 800 tough mbn? Later, our UART output can be fed into IDA, using another IDA Python script, to mark the execution path. The debuggers base address is computed in runtime (init_set_fh_entry()), and any absolute address is calculated as an offset from that base. You do not have permission to delete messages in this group, Either email addresses are anonymous for this group or you need the view member email addresses permission to view the original message. Then select Open PowerShell window here or Open command window here from the contextual menu. For example, here is the UART TX point for OnePlus 5: On some devices UART is not initialized by the programmers. A working 8110 4G firehose found, should be compatible with any version.
