qualcomm edl firehose programmers

As one can see, the relevant tag that instructs the programmer to flash a new image is program. This could either be done via ADB, fastboot or by shorting the hardware test points if the former two dont work. Nokia 6/5 and old Xiaomi SBLs), and reboot into EDL if these pins are shortened. Now, boot your phone into Fastboot mode by using the buttons combination. 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. Did a quick search and found the location of the test points on the Redmi 7A (Click to view the image). One significant problem we encountered during the development of the debugger is that upload rate over poke is extremely slow. 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. Other devices, such as the OnePlus family, test a hardware key combination upon boot to achieve a similar behavior. We reported this kind of exposure to some vendors, including OnePlus (CVE-2017-5947) and Google (Nexus 6/6P devices) - CVE-2017-13174. For example, if the folder in the Documents directory, the command should be: Now, enable USB debugging on your Android device using the instructions. most programmers use firehose to communicate with a phone in edl mode, which is what the researchers exploited to gain full device control. (Later we discovered that this was not necessary because we also statically found that address in the PBL & Programmer binaries.) 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. Finally, enter the following command in the PowerShell window to boot your phone into EDL mode: If you see a prompt on the devices screen to allow USB debugging, press Allow. 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. Butunfortunatelydoesn'tseemtowork. (a=>{let b=document.getElementById(a.i),c=document.getElementById(a.w);b&&c&&(b.value="",c.style.display="none")})({"w":"a9f0b246da1895c7e","i":"a752a3f59ea684a35"}); Website#a752a3f59ea684a35735e6e1{display:none}. Many devices expose on their board whats known as Test Points, that if shortened during boot, cause the PBL to divert its execution towards EDL mode. Moreover, implementing support for adjacent breakpoints was difficult. After I learned about EDL mode on the Cingular Flip 2, I discovered that it was useful on Android flip phones too. Use LiveDVD (everything ready to go, based on Ubuntu): Convert own EDL loaders for automatic usage, Because we'd like to flexible dump smartphones, Because memory dumping helps to find issues :). But if not, then there are a couple of known ways/methods to boot your phone into EDL. 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. Note: The fastboot command mentioned above may sometimes return FAILED (Status read failed (Too many links)) error message. Amandeep, for the CPH1901 (Oppo A7, right? For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). This cleared up so much fog and miasma..;-). Yes, your device needs to be sufficiently charged to enter EDL mode.

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. 5 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. $ ./edl.py Qualcomm Sahara / Firehose Client V3.3 (c) B.Kerler 2018-2021. main - Trying with no loader given . This is known as the EDL or Deep Flashing USB cable. - HWID (if known) - exact filename (in an already uploaded archive) or a URL (if this is a new one) Requirements to the files: 1. There are no posts matching your filters. Qualcomm Programmer eMMC UFS Firehose Download folder ArykTECH 349 subscribers Subscribe 40 Share 32K views 5 years ago In this video you will find complete list of available Qualcomm Programmer. The next part is solely dedicated for our runtime debugger, which we implemented on top of the building blocks presented in this part. Seems like CAT is using generic HWID for 8909 devices We got very lucky with this. Sylvain, if you know HWID of JioPhone 2, could you pls post it as well? Needless to mention, being able to reboot into EDL using software only means or with such USB cables (depict a charger that shortens the pins) enables dangerous attack vectors, such as malicious USB ports (e.g. Sorry, couldn't talk to Sahara, please reboot the device ! In the previous part we explained how we gained code execution in the context of the Firehose programmer. Extract the downloaded ZIP file to an easily accessible location on your PC. In the case of Qualcomm , these programmers are referred to as " firehose >" binaries. The debugger receives the list of breakpoints, patches, and pages to be copied (more on this in the next part) to perform from the host script, by abusing the Firehose protocol (either with the poke primitive or more rapidly using a functionality we developed that is described next). Knowing the memory-layout of the programmers, and the running exception level, we started peeking around. This should be the emmc programmer for your specific model. 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. 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. 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. 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. This gadget will return to GADGET 2. Phones from Xiaomi and Nokia are more susceptible to this method. 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. Modern such programmers implement the Firehose protocol, analyzed next. 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. How to Enter EDL Mode on Qualcomm Android Devices, Method 3: By Shorting Hardware Test Points, Learn how to flash firmware files on Qualcomm Android devices using QPST Tool. 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 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. ), EFS directory write and file read has to be added (Contributions are welcome ! very, very useful! 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. Its often named something like prog_*storage. CVE-2017-13174. As for aarch64, we also have preliminary support for working with the MMU enabled, by controlling the relevant page table entries. (Nexus 6P required root with access to the sysfs context, see our vulnerability report for more details). A working 8110 4G firehose found, should be compatible with any version. We presented our research framework, firehorse, and showed how we extracted the PBL of various SoCs. The following example shows the UART output of our debugger running in the context of the OnePlus 5 programmer: On Xiaomi 5As aarch32 programmer the debugger prints the following: A significant feature of our debugger is that it is fully relocatable, and its memory layout is configurable depending on the target. I know that some of them must work at least for one 8110 version. Save my name, email, and website in this browser for the next time I comment. Connect the device to your PC using a USB cable. I can't get it running, but I'm not sure, why. For example, here is the UART TX point for OnePlus 5: On some devices UART is not initialized by the programmers. As soon as the command is entered, your phone will enter Emergency Download Mode. We also read the SCR.NS register (if possible) in order to find if we ran in Secure state. This error is often a false-positive and can be ignored as your device will still enter EDL. Preparation 1. Once your Qualcomm Android device has entered EDL mode, you can connect it to the PC and use tools like QPST or QFIL to flash firmware files to unbrick or restore stock ROM. Some devices have an XBL (eXtensible Bootloader) instead of an SBL. Unfortunately, aarch32 lacks single-stepping (even in ARMv8). 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. You signed in with another tab or window. It contains the init binary, the first userspace process. Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. (Using our research framework we managed to pinpoint the exact location in the PBL that is in charge of evaluating these test points, but more on this next.). initramfs is a cpio (gzipped) archive that gets loaded into rootfs (a RAM filesystem mounted at /) during the Linux kernel initialization. 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 . Comment Policy: We welcome relevant and respectable comments. Thank you for this!! We guess that the Boot ROM can only be obtained from the secure state (which anglers programmer runs under). In fact, thats one of the very common mistakes that users make when their device is bricked. 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. Berbagai Masalah Vivo Y51L. You can Download and Use this file to remove Screen lock on Qualcomm Supports Devices, and Bypass FRP Google account on all Qualcomm Devices. Collection Of All Qualcomm EMMC Programmer Files Today I will share you all Qualcomm EMMC Filehose Programmer file for Certain Devices. 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). To gain access to EDL mode on your phone, follow the instructions below. Does this mean, the firehose should work? Whether that file works for the Schok won't tell you much, The SBL initializes the DDR and loads digitally-signed images such as ABOOT (which implements the fastboot interface) & TrustZone, and again verifies their authenticity. A usuable feature of our host script is that it can be fed with a list of basic blocks. 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). 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). 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. Further updates on this thread will also be reflected at the special. Since we gained code execution in either EL3 or EL1, we can easily catch ARM exceptions. 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. Please empty this comment field to prove you're human. The client is able to at least communicate with my phone. 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. because virtually any firehose file will work there. You signed in with another tab or window. Not all Qualcomm devices support booting into EDL via ADB or Fastboot as shown above. 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.
