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. Receive the freshest Android & development news right in your inbox! As an example, the figures below show these EDL test points on two different OEM devices Redmi Note 5A (on the left) and Nokia 6 (on the right). So breakpoints are simply placed by replacing instructions with undefined ones which cause the undefined instruction handler, that we hooked, to be executed. To start working with a specific device in EDL , you need a programmer . Sorry for the false alarm. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Multiple usb fixes. EDL or Emergency DownLoad Mode is a special boot mode in Qualcomm Android devices that allows OEMs to force-flash firmware files. ), 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. This method is for when your phone can boot into the OS and you want to boot it into EDL mode for restoring the stock firmware. Unfortunately, aarch32 lacks single-stepping (even in ARMv8). 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 . 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. 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. The availability of these test points varies from device to device, even if they are from the same OEM. I know that some of them must work at least for one 8110 version. Your device needs to have a usb pid of 0x9008 in order to make the edl tool work. However, thats not the case always. Thank you for this!! Could anyone please test the attached firehose on 8110 4G (TA-1059 or TA-1048) or 2720 Flip? 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 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. However,theOEMhashisexactlythesameastheTA-1059. Updated on, P.S. 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? Doing so will allow us to research the programmer in runtime. Rahul, most (if not all) Xiaomi phones would need the third method to get into EDL mode. 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. Research & Exploitation framework for Qualcomm EDL Firehose programmers. For most devices the relevant UART points have already been documented online by fellow researchers/engineerings. For example, on OnePlus 5: Now that we can conveniently receive output from the device, were finally ready for our runtime research. Specifically, the host uploads the following data structure, to FIREHORSE_BASE + ADDR_SCRATCH_OFFSET: The inner structures are described here (32 bit) and here (64 bit). 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. The first part presents some internals of the PBL, EDL, Qualcomm Sahara and programmers, focusing on Firehose. 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! So, I have an idea how we could deal with this, and will check this idea tomorrow. In the previous part we explained how we gained code execution in the context of the Firehose programmer. We could have not dumped everything because then we would risk in device hangs, reboots, etc, since some locations are not of the RAM. 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 ! Additional license limitations: No use in commercial products without prior permit. ALEPH-2017029. We also read the SCR.NS register (if possible) in order to find if we ran in Secure state. P.S. Please take a look at the image posted on this website, it illustrates the correct EDL test points for the Oppo A7. Alcatel. It can be found online fairly easily though. So, let's collect the knowledge base of the loaders in this thread. The debuggers base address is computed in runtime (init_set_fh_entry()), and any absolute address is calculated as an offset from that base. Luckily for us, it turns out that most Android devices expose a UART point, that can be fed into a standard FTDI232. Research & Exploitation of Qualcomm EDL Firehose Programmers: From PBL (Boot ROM) Extraction, Research & Analysis to Secure Boot Bypass in Nokia 6. . Similarly, in aarch64 we have the VBAR_ELx register (for each exception level above 0). Seems like CAT is using generic HWID for 8909 devices We got very lucky with this. imem is a fast-on-chip memory used for debugging and dma (direct memory access) transactions and is proprietary to qualcomm chipsets. sbl maintains the SBL contextual data, where its first field points to a copy of pbl2sbl_data. No, that requires knowledge of the private signature keys. these programmers are often leaked from OEM device repair labs. Triedonboth,8110&2720. HWID: 0x000940e100420050 (MSM_ID:0x000940e1,OEM_ID:0x0042,MODEL_ID:0x0050). Further updates on this thread will also be reflected at the special. Xiaomi) also publish them on their official forums. 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. you can check other tutorialshere to help. A usuable feature of our host script is that it can be fed with a list of basic blocks. JavaScript is disabled. 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. You can upload your own or analyze the files already uploaded to the thread, and let everyone know which model has which fitting firehose loader. but edl mode is good choice, you should be able to wipe data and frp . We guess that the Boot ROM can only be obtained from the secure state (which anglers programmer runs under). But newer Schok Classic phones seem to have a fused loader. XDA Developers was founded by developers, for developers. If you install python from microsoft store, "python setup.py install" will fail, but that step isn't required. It may not display this or other websites correctly. Onetouch Idol 3 Android Development . You signed in with another tab or window. Meaninganyworkingloader,willworkonbothofthem(andhopefullyfortheotheronesaswell). $ ./edl.py Qualcomm Sahara / Firehose Client V3.3 (c) B.Kerler 2018-2021. main - Trying with no loader given . 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. You are using an out of date browser. To know about your device-specific test points, you would need to check up on online communities like XDA. You can Download and Use this file to remove Screen lock on Qualcomm Supports Devices, and Bypass FRP Google account on all 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. sahara - ----- HWID: 0x0005f0e100000000 (MSM_ID:0x0005f0e1,OEM_ID:0x0000,MODEL_ID:0x0000) CPU detected: "MSM8996Pro" PK_HASH . Download the latest Android SDK tools package from. For example, here is the UART TX point for OnePlus 5: On some devices UART is not initialized by the programmers. 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. Note: The fastboot command mentioned above may sometimes return FAILED (Status read failed (Too many links)) error message. As for aarch64, we also have preliminary support for working with the MMU enabled, by controlling the relevant page table entries. Nokia 6/5 and old Xiaomi SBLs), and reboot into EDL if these pins are shortened. After running our chain, we could upload to and execute our payload at any writable memory location. 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. TA-1048, TA-1059 or something else? We provide solutions: FRP Bypass, Firmware Flashing, IMEI repair, Unlock Bootloader, Rooting & many more stuff. For details on how to get into EDL, please see our blog post. 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. (TheyactuallybothhaveadifferentOEMhash,whichprobablymeanstheyaredifferentlysigned,no?). 11. 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. GADGET 1 Our first gadget generously gives us control over X0-X30: GADGET 2: The next gadget call X4, which we control using GADGET 1: GADGET 3: We set X4 to 0xF03DF38, a gadget which writes X1 (which we control using GADGET 1) to the EL3 System Control Register (SCTLR_EL3): The LSB of SCTLR_EL3 controls the MMU (0 = disabled). This list can be generated using the following IDA Python script: For example, here is the list of basic blocks generated for the pbl_sense_jtag_test_edl function discussed in Part 1: Then, one can call our breakpoints managers break_function or trace_function in order to break on a functions entry, or break on all basic blocks, effectively tracing its execution. - HWID (if known) - exact filename (in an already uploaded archive) or a URL (if this is a new one) Requirements to the files: 1. Before that, we did some preliminary analysis of the MSM8937/MSM8917 PBL, in order to understand its layout in a high-level perspective. As one can see, the relevant tag that instructs the programmer to flash a new image is program. 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. For a better experience, please enable JavaScript in your browser before proceeding. Later, the PBL will actually skip the SBL image loading, and go into EDL mode. For Nokia 6 (aarch32), for example, we get the following UART log, that indicates we are in EL3: The Nexus 6P (angler) aarch64 programmer also runs in EL3: OnePlus 5s programmer, on the other hand, runs in EL1: We can see that the most recent programmer has the least privilege level, a good sign from Qualcomm. Gadgets Doctor Provides the best solution to repair any kind of Android or features phones very easily. 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. It looks like we were having a different problem with the Schok Classic, not a fused loader issue. Unlike Fastboot, Download, and Recovery modes on Android, which reside in the Secondary Bootloader (SBL), PBL resides within the ROM and so it could not be corrupted due to software errors (again, like a wrong flash). very, very useful! 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). Part 3, Part 4 & Part 5 are dedicated for the main focus of our research memory based attacks. If it is in a bootloop or cannot enter the OS, move to the second method. 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. For some programmers our flashed data did not remain in memory. Rebooting into EDL can also happen from the Platform OS itself, if implemented, and if adb access is allowed, by running adb reboot edl. Connect the phone to your PC while its in Fastboot mode. 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). 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. The OEM flash tools can only communicate with a device and flash it through the said modes. I don't think I've ever had a Qualcomm EDL cable work on a single LG phone I have ever had over the past decade. I have the firehose/programmer for the LG V60 ThinQ. 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). Analyzing several programmers binaries quickly reveals that commands are passed through XMLs (over USB). 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. We presented our research framework, firehorse, and showed how we extracted the PBL of various SoCs. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. In this part we described our debugging framework, that enabled us to further research the running environment. To exploit that, we first flash our data on some bogus / backup partition, and then upload a small, Egg Hunter, that searches the relevant memory for our previously uploaded data (i.e. Not all Qualcomm devices support booting into EDL via ADB or Fastboot as shown above. And thus, there would be no chance of flashing the firmware to revive/unbrick the device. 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). You also wouldnt want your device to turn off while youre flashing the firmware, which could lead to unexpected results. As one can see, there are such pages already available for us to abuse. The client does report the programmer successfully uploaded, but I suspect that's not true. In that case, youre left with only one option, which is to short the test points on your devices mainboard. Looking to work with some programmers on getting some development going on this. Digging into the programmers code (Xiaomi Note 5A ugglite aarch32 programmer in this case) shows that its actually an extended SBL of some sort.
