To ensure that we can replace arbitrary instructions and not get hit with data aborts while doing so (due to non-writable pages), we either disable the MMU completely (aarch64), or in aarch32, much conveniently elevate all of the domains to manager, by writing 0xFFFFFFFF to the DACR register. Interestingly, in the actual SBL of ugglite, this series of initialization callbacks looks as follows: Therefore, they only differ in the firehose_main callback! Some of these powerful capabilities are covered extensively throughout the next parts. 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. The SBL initializes the DDR and loads digitally-signed images such as ABOOT (which implements the fastboot interface) & TrustZone, and again verifies their authenticity. While its best you use a firmware which includes a programmer file, you can (in severe cases) use the programmer file for a Qualcomm EDL mode varies across Qualcomm devices so. We end with a (TheyactuallybothhaveadifferentOEMhash,whichprobablymeanstheyaredifferentlysigned,no?). . 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. Kindly please update whether it works as I'm on the same boat albeit with a different device (it's a projector with a battery based on android). emmc Programs File. This cleared up so much fog and miasma..;-). main - Waiting for the device main - Device detected :) main - Mode detected: sahara Device is in EDL mode .. continuing. You also wouldnt want your device to turn off while youre flashing the firmware, which could lead to unexpected results. (, 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. Multiple usb fixes. the Egg). After that select the programmer file prog_emmc_firehose_8917_ddrMBN. This method has a small price to pay. 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. Luckily for us, it turns out that most Android devices expose a UART point, that can be fed into a standard FTDI232. We describe the Qualcomm EDL (Firehose) and Sahara Protocols. 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. In the previous chapters we presented Qualcomm Sahara, EDL and the problem of the leaked Firehose programmers. Install normal QC 9008 Serial Port driver (or use default Windows COM Port one, make sure no exclamation is seen), Test on device connect using "UsbDkController -n" if you see a device with pid 0x9008, Copy all your loaders into the examples directory, Or rename Loaders manually as "msmid_pkhash[8 bytes].bin" and put them into the Loaders directory, Send AT!BOOTHOLD and AT!QPSTDLOAD to modem port or use, Send AT!ENTERCND="A710" and then AT!EROPTION=0 for memory dump, Secure loader with SDM660 on Xiaomi not yet supported (EDL authentification), VIP Programming not supported (Contributions are welcome ! but edl mode is good choice, you should be able to wipe data and frp . In this mode, the device identifies itself as Qualcomm HS-USB 9008 through USB. Qualcomm Firehose Programmer file Collection: Download Prog_firehose files for All Qualcomm SoC. Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. It seems like EDL mode is only available for a split second and then turn off. Could anyone please test the attached firehose on 8110 4G (TA-1059 or TA-1048) or 2720 Flip? 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). Hi, A usuable feature of our host script is that it can be fed with a list of basic blocks. Sylvain, if you know HWID of JioPhone 2, could you pls post it as well? Looking to work with some programmers on getting some development going on this. 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. This error is often a false-positive and can be ignored as your device will still enter EDL. The client does report the programmer successfully uploaded, but I suspect that's not true. 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). As soon as the command is entered, your phone will enter Emergency Download Mode. Credits & Activations. For some programmers our flashed data did not remain in memory. Programmer binaries are used by Qualcomm's Sahara protocol, which works in Emergency Download mode, commonly known as EDL, and is responsible for flashing a given device with a specific SoC.As a developer on GitHub claims, programmers are SoC specific but devices only. 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. For a better experience, please enable JavaScript in your browser before proceeding. Since the PBL is a ROM resident, EDL cannot be corrupted by software. Google has patched CVE-2017-13174 in the December 2017 Security Bullet-in. MSM-based devices contain a special mode of operation - Emergency Download Mode (EDL). Improved streaming stuff, Qualcomm Sahara / Firehose Attack Client / Diag Tools. Nokia 6/5 and old Xiaomi SBLs), and reboot into EDL if these pins are shortened. Save my name, email, and website in this browser for the next time I comment. The debuggers base address is computed in runtime (init_set_fh_entry()), and any absolute address is calculated as an offset from that base. Research & Exploitation framework for Qualcomm EDL Firehose programmers. For most devices the relevant UART points have already been documented online by fellow researchers/engineerings. Deeper down the rabbit hole, analyzing firehose_main and its descendants sheds light on all of the Firehose-accepted XML tags. You signed in with another tab or window. Why and when would you need to use EDL Mode? Catching breakpoints is only one side of the coin, the other recovery and execution of the original instruction. We provide solutions: FRP Bypass, Firmware Flashing, IMEI repair, Unlock Bootloader, Rooting & many more stuff. Just plug in your device to the wall charger for at least 30-40 minutes so that it gets sufficiently charged. I know that some of them must work at least for one 8110 version. The only thing we need to take care of is copying the original stack and relocating absolute stack address. 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. you can check other tutorialshere to help. EDL mode is entered by plugging the cable while having * and # pressed at the same time. The availability of these test points varies from device to device, even if they are from the same OEM. I dont think the mother board is receiving power as the battery is dead. In addition, OnePlus 5s programmers runs in EL1, so we used SCTLR_EL1 instead of the EL3 counterpart. Unfortunately, aarch32 lacks single-stepping (even in ARMv8). In that case, youre left with only one option, which is to short the test points on your devices mainboard. 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. This device has an aarch32 leaked programmer. 11. JavaScript is disabled. Thanks for visiting us, Comment below if you face any problem With Qualcomm Prog eMMC Firehose Programmer file Download problem, we will try to solve your problem as soon as possible. We also read the SCR.NS register (if possible) in order to find if we ran in Secure state. 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. ), EFS directory write and file read has to be added (Contributions are welcome ! You can Download and Use this file to remove Screen lock on Qualcomm Supports Devices, and Bypass FRP Google account on all Qualcomm Devices. Extract the downloaded ZIP file to an easily accessible location on your PC. For Oneplus 6T, enter #801# on dialpad, set Engineer Mode and Serial to on and try : Published under MIT license This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. Finding the address of the execution stack. It's already in the above archive. 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). Meaninganyworkingloader,willworkonbothofthem(andhopefullyfortheotheronesaswell). Connect the phone to your PC while its in Fastboot 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) If emmc flash is used, remove battery, short DAT0 with gnd, connect battery, then remove short. Your phone should now reboot and enter EDL mode. 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. For details on how to get into EDL, please see our blog post. A defining property of debuggers is to be able to place breakpoints. Read our comment policy fully before posting a comment. 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. 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. To defeat that, we devised a ROP chain that disables the MMU itself! However discovering the point on undocumented devices is an easy task. Butunfortunatelydoesn'tseemtowork. Xiaomi) also publish them on their official forums. 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 . 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.
