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). ), 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. Knowing the memory-layout of the programmers, and the running exception level, we started peeking around. Research & Exploitation framework for, A couple of years ago, it is easy to unbrick a Xiaomi device through Emergency Download Mode (, Programming & Flashing. To boot your phone into EDL mode using the test point method, you will need to expose the devices mainboard and use a metal tweezer (or a conductive metal wire) to short the points, and then plug the device to your PC or to the wall charger over USB. Receive the freshest Android & development news right in your inbox! Your device needs to have a usb pid of 0x9008 in order to make the edl tool work.

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 (. (For debugging during our ROP chain development, we used gadgets that either reboot the device, or cause infinite loops, in order to indicate that our gadgets were indeed executed). For most devices the relevant UART points have already been documented online by fellow researchers/engineerings. In addition, rebooting into EDL by software is done by asserting the LSB of the 0x193D100 register (also known as tcsr-boot-misc-detect) I dont think the mother board is receiving power as the battery is dead. (, 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. ALEPH-2017029. GADGET 3: The next gadget calls R12 (that we control, using the previous gadget): GADGET 4: We set R12 to 080081AC, a gadget that copies TTBR0 to R0: This will return to GADGET 3, with R0 = TTBR0. 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. Exploiting Qualcomm EDL Programmers (4): Runtime Debugger. Some OEMs (e.g. 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). The init function is in charge of the following: This struct contains the following fields: (The shown symbols are of course our own estimates.). A usuable feature of our host script is that it can be fed with a list of basic blocks. Apr 1, 2019 350 106 Innernetz www.noidodroid.com . Just plug in your device to the wall charger for at least 30-40 minutes so that it gets sufficiently charged. For example, here is the UART TX point for OnePlus 5: On some devices UART is not initialized by the programmers. Later, our UART output can be fed into IDA, using another IDA Python script, to mark the execution path. He loves to publish tutorials on Android IOS Fixing. to get back the 0x9008 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). very, very useful! We presented our research framework, firehorse, and showed how we extracted the PBL of various SoCs. Despite that, we can recover most breakpoints each time a breakpoint is hit, we simply reconstruct all of the others, losing only breakpoints that occur in succession. Some devices have boot config resistors, if you find the right ones you may enforce booting to sdcard instead of flash. In aarch32, vector tables are pointed by the VBAR registers (one for each security state). In order to achieve a fast upload nevertheless, we used the following technique: for each poke we add another XML attribute, which encapsulates our data. Credits: Aleph Security for their in-depth research on Qualcomms EDL programmer, Nothing Phone 1 OTA Software Updates: Download and Installation Guide, Root Nothing Phone 1 with Magisk A Step-by-Step Guide, Unlock Bootloader on Nothing Phone 1 and Relock it A Beginners Guide, Enter Fastboot and Recovery Modes on Nothing Phone 1 [Guide], Unlock Bootloader on Google Pixel and Nexus Devices A Comprehensive Guide, Does EDL need battery?as my battery is completely dead do I have to charge the battery and then enter EDL? 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. JavaScript is disabled. However discovering the point on undocumented devices is an easy task. 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 :). EDL mode is entered by plugging the cable while having * and # pressed at the same time. So, I know the only file from this archive for sure: Filename: prog_emmc_firehose_8909_alcF.mbn. 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. Later, the PBL will actually skip the SBL image loading, and go into EDL mode. Ive managed to fix a bootloop on my Mi A2. We believe other PBLs are not that different. (Part 3) <-- . Exploiting Qualcomm EDL Programmers (3): Memory-based Attacks & PBL Extraction. The only thing we need to take care of is copying the original stack and relocating absolute stack address. Improved streaming stuff, Qualcomm Sahara / Firehose Attack Client / Diag Tools. 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. 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. You can Download and Use this file to remove Screen lock on Qualcomm Supports Devices, and Bypass FRP Google account on all Qualcomm Devices. 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. 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. Interestingly, there is a positive trend of blocking these commands in locked Android Bootloaders. 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. (Nexus 6P required root with access to the sysfs context, see our vulnerability report for more details). For such devices, it can be dumped straight from memory (sadly, it will not let us debug crashes): In order for our code to write to the UART interface, we simply call one of the programmers already available routines. 11. 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. 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). Then select Open PowerShell window here or Open command window here from the contextual menu. 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. EDL implements Qualcomms 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). This method is for when your phone cannot enter the OS but can boot into Fastboot mode (Also sometimes referred to as Bootloader mode). Analyzing several Firehose programmers binaries quickly reveals that this is an XML over USB protocol. In this part we described our debugging framework, that enabled us to further research the running environment. Deeper down the rabbit hole, analyzing firehose_main and its descendants sheds light on all of the Firehose-accepted XML tags. Qualcomm Sahara / Firehose Client (c) B.Kerler 2018-2019. When in this mode, the device identifies itself as Qualcomm HS-USB QDLoader 9008 over a USB connection. Gadgets Doctor Provides the best solution to repair any kind of Android or features phones very easily. In this part we extend the capabilities of firehorse even further, making it . For example, on OnePlus 5: Now that we can conveniently receive output from the device, were finally ready for our runtime research. It contains the init binary, the first userspace process. HWID: 0x009600e100000000 (MSM_ID:0x009600e1,OEM_ID:0x0000,MODEL_ID:0x0000), PK_HASH: 0xcc3153a80293939b90d02d3bf8b23e0292e452fef662c74998421adad42a380f. Some fields worth noting include sbl_entry which is later set to the SBLs entry point, and pbl2sbl_data which contains parameters passed to the soon-to-be-jumped-to SBL (see next). When such an exception occurs, a relevant handler, located at an offset from the vector base address, is called. The SBL initializes the DDR and loads digitally-signed images such as ABOOT (which implements the fastboot interface) & TrustZone, and again verifies their authenticity. (TheyactuallybothhaveadifferentOEMhash,whichprobablymeanstheyaredifferentlysigned,no?). We presented our research framework, firehorse, and showed how we extracted the PBL of various SoCs. It may not display this or other websites correctly. The reset handler (address 0x100094) of the PBL roughly looks as follows (some pseudo-code was omitted for readability). the Egg). We could have not dumped everything because then we would risk in device hangs, reboots, etc, since some locations are not of the RAM.

Why not reconstruct the 32-bit page table? A domain set to manager instructs the MMU to always allow access (i.e. After that select the programmer file prog_emmc_firehose_8917_ddrMBN. In this mode, the device identifies itself as Qualcomm HS-USB 9008 through USB. Qualcomm's EDL & Firehose demystified. For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). GADGET 5: The next gadget copies R0 to [R4], which we can control using GADGET 2: We return from this gadget to the original caller. CVE-2017 . 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. ), EFS directory write and file read has to be added (Contributions are welcome ! 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). but edl mode is good choice, you should be able to wipe data and frp . Save my name, email, and website in this browser for the next time I comment. So, thanks to anonymous Israeli volunteers, we now have a working firehose loader for all Nokia 2720 Flip variants. Please take a look at the image posted on this website, it illustrates the correct EDL test points for the Oppo A7. So, let's collect the knowledge base of the loaders in this thread. Tested on our Nexus 6P, trying to read from its PBL physical address (0xFC010000), instantly resulted in a system reboot. Having a short glimpse at these tags is sufficient to realize that Firehose programmers go way beyond partition flashing. For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). Must be easily downloadable (no turbobits/dfiles and other adware), preferably a direct link; 2. 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. To gain access to EDL mode on your phone, follow the instructions below. If your device is semi bricked and entered the usb pid 0x900E, there are several options Thread starter sloshnmosh; Start date Jun 12, 2018; Forums. Our XML Hunter searches the relevant memory for such pokes, and decodes the data, contained in the supplied attribute. A defining property of debuggers is to be able to place breakpoints. Modern such programmers implement the Firehose protocol, analyzed next. First, the PBL will mark the flash as uninitialized, by setting pbl->flash_struct->initialized = 0xA. 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.
