qualcomm edl firehose programmers

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). It looks like we were having a different problem with the Schok Classic, not a fused loader issue. Now, boot your phone into Fastboot mode by using the buttons combination. Credits & Activations. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. noidodroid Senior Member. We then continued by exploring storage-based attacks. Analyzing several programmers' binaries quickly reveals that commands are passed through XMLs (over USB). This gadget will return to GADGET 2. There are many guides [1,2,3,4,5,6,7] across the Internet for unbricking Qualcomm-based mobile devices. CVE-2017-13174. During this process, EDL implements the Firehose/Sahara protocol and acts as a Secondary Bootloader to accept commands for flashing. My proposed format is the. He loves to publish tutorials on Android IOS Fixing. In aarch32, vector tables are pointed by the VBAR registers (one for each security state). Interestingly, in the actual SBL of ugglite, this series of initialization callbacks looks as follows: Therefore, they only differ in the firehose_main callback! In the next part we display the cherry on top a complete Secure Boot exploit against Nokia 6 MSM8937. 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. Moreover, implementing support for adjacent breakpoints was difficult. Could anyone please test the attached firehose on 8110 4G (TA-1059 or TA-1048) or 2720 Flip? - HWID (if known) - exact filename (in an already uploaded archive) or a URL (if this is a new one) Requirements to the files: 1. but edl mode is good choice, you should be able to wipe data and frp . In the case of Qualcomm , these programmers are referred to as " firehose >" binaries. The SBL initializes the DDR and loads digitally-signed images such as ABOOT (which implements the fastboot interface) & TrustZone, and again verifies their authenticity. For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). GADGET 2: Similarly to the aarch32 case, we copy the original stack s.t. It can be found online fairly easily though. The client does report the programmer successfully uploaded, but I suspect that's not true. One possible explanation for their existence is that they are old entries from the APPS PBL (which indeed sets TTBR0 to 0xFE800000). Which version of 8110 do you have? very, very useful! Gadgets Doctor Provides the best solution to repair any kind of Android or features phones very easily. In this mode, the device identifies itself as Qualcomm HS-USB 9008 through USB. Hopefully we will then be able to find a suitable page (i.e one that is both writable and executable), or change (by poke) the access permissions of an existing one. ), EFS directory write and file read has to be added (Contributions are welcome ! I've discovered a few that are unfused (Orbic Journey, Coolpad Snap, and Schok Classic). Why not reconstruct the 32-bit page table? ImageLoad is the function that is in charge of loading the next bootloaders, including ABOOT: ImageLoad starts by calling (using the loop_callbacks routine) a series of initialization functions: firehose_main eventually falls into the main firehose loop, and never returns. 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. . . You can Download and Use this file to remove Screen lock on Qualcomm Supports Devices, and Bypass FRP Google account on all Qualcomm Devices. 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. The figure on the right shows the boot process when EDL mode is executed. Having a short glimpse at these tags is sufficient to realize that Firehose programmers go way beyond partition flashing. To do so, we devised a ROP-based exploit, in order to leak the TTBR0 register, which holds the base address of the page table. Looking to work with some programmers on getting some development going on this. When shorted during the boot, these test points basically divert the Primary Bootloader (PBL) to execute EDL mode. My proposed format is the following: - exact filename (in an already uploaded archive) or a URL (if this is a new one). 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. To start working with a specific device in EDL , you need a programmer . A defining property of debuggers is to be able to place breakpoints. No, that requires knowledge of the private signature keys. Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. JavaScript is disabled. We often like to refer to this device state as a Hard-brick. complete Secure-Boot bypass attack for Nokia 6 MSM8937, that uses our exploit framework. (Nexus 6P required root with access to the sysfs context, see our vulnerability report for more details). It may not display this or other websites correctly. In addition, rebooting into EDL by software is done by asserting the LSB of the 0x193D100 register (also known as tcsr-boot-misc-detect) $ ./edl.py Qualcomm Sahara / Firehose Client V3.3 (c) B.Kerler 2018-2021. main - Trying with no loader given . So, let's collect the knowledge base of the loaders in this thread. 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). Please take a look at the image posted on this website, it illustrates the correct EDL test points for the Oppo A7. emmc Programs File. 11. Unfortunately, aarch32 lacks single-stepping (even in ARMv8). This is known as the EDL or Deep Flashing USB cable. All of these guides make use of Emergency Download Mode (EDL), an alternate boot-mode of the Qualcomm Boot ROM (Primary Bootloader). Moving to 32-bit undefined instructions regardless of the original instructions size has not solved the issue either our plan was to recover the adjacent word while dealing with the true breakpoint, without any side-effects whatsoever. imem is a fast-on-chip memory used for debugging and dma (direct memory access) transactions and is proprietary to qualcomm chipsets. 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. We must be at any moment prepared for organized resistance against the pressure from anyone trying to take away what's ours. 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. It seems the RPM PBL is in the 0xfc000000-0xfc0040000 range, where the MODEM PBL is in the 0xfc004000-0xfc010000 range. Deeper down the rabbit hole, analyzing firehose_main and its descendants sheds light on all of the Firehose-accepted XML tags. The init function is in charge of the following: This struct contains the following fields: (The shown symbols are of course our own estimates.). TA-1048, TA-1059 or something else? 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! 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. You also wouldnt want your device to turn off while youre flashing the firmware, which could lead to unexpected results. Connect the phone to your PC while its in Fastboot mode. Rahul, most (if not all) Xiaomi phones would need the third method to get into EDL mode. It seems like EDL mode is only available for a split second and then turn off. 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). To start working with a specific device in EDL, you need a programmer. Download the latest Android SDK tools package from. Analyzing their handlers reveals the peek and poke tags expect the following format: Adding this to our research tool, allowed us to easily explore susceptible devices. I have made a working package for Nokia 8110 for flashing with cm2qlm module. Multiple usb fixes. So can you configure a firehose for nokia 2720/800? Programmers are pieces of low-level software containing raw flash/read-write functionality that allows for reflashing, similar to Samsung's Odin mode or LG's flash. For some programmers our flashed data did not remain in memory. Special care was also needed for Thumb. As for aarch64, we also have preliminary support for working with the MMU enabled, by controlling the relevant page table entries. It's already in the above archive. 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? Some OEMs (e.g. GADGET 2: We get control of R4-R12,LR using the following gadget: Controlling LR allows us to set the address of the next gadget - 0x0801064B. 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). This should be the emmc programmer for your specific model. For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). Finally, enter the following command in PowerShell to boot your phone into EDL mode. 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. Nokia 6/5 and old Xiaomi SBLs), and reboot into EDL if these pins are shortened. We end with a 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. 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. To implement breakpoints, we decided to abuse undefined instruction exceptions. Ive managed to fix a bootloop on my Mi A2. First, the PBL will mark the flash as uninitialized, by setting pbl->flash_struct->initialized = 0xA. 5 For example, Nexus 6Ps page tables, whose base address is at 0xf800000 is as follows: At this point no area seemed more attractive than the other. chargers). 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 :). (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). If you install python from microsoft store, "python setup.py install" will fail, but that step isn't required. 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. 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). Research & Exploitation framework for Qualcomm EDL Firehose programmers, By Roee Hay (@roeehay) & Noam Hadad, Aleph Reseserch, HCL Technologies. 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. Modern such programmers implement the Firehose protocol. (Later we discovered that this was not necessary because we also statically found that address in the PBL & Programmer binaries.) 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). This method has a small price to pay. Some of them will get our coverage throughout this series of blog posts. 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. A domain set to manager instructs the MMU to always allow access (i.e. Analyzing several Firehose programmers binaries quickly reveals that this is an XML over USB protocol. r"C:\Program Files (x86)\Qualcomm\QPST437\bin\fh_loader.exe", r"C:\Program Files (x86)\Qualcomm\QPST437\bin\QSaharaServer.exe". The reset handler (address 0x100094) of the PBL roughly looks as follows (some pseudo-code was omitted for readability). 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. Phones from Xiaomi and Nokia are more susceptible to this method. 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. We then read the leaked register using the peek primitive: Hence TTBR0 = 0x200000! A working 8110 4G firehose found, should be compatible with any version. 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. 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. 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). Research & Exploitation framework for Qualcomm EDL Firehose programmers. Onetouch Idol 3 Android Development . Our XML Hunter searches the relevant memory for such pokes, and decodes the data, contained in the supplied attribute. 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. these programmers are often leaked from OEM device repair labs. (, 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. Collection Of All Qualcomm EMMC Programmer Files Today I will share you all Qualcomm EMMC Filehose Programmer file for Certain Devices. A usuable feature of our host script is that it can be fed with a list of basic blocks. Sorry, couldn't talk to Sahara, please reboot the device ! HWID: 0x009600e100000000 (MSM_ID:0x009600e1,OEM_ID:0x0000,MODEL_ID:0x0000), PK_HASH: 0xcc3153a80293939b90d02d3bf8b23e0292e452fef662c74998421adad42a380f. 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 (. 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. EDL or Emergency DownLoad Mode is a special boot mode in Qualcomm Android devices that allows OEMs to force-flash firmware files. 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. We reported this kind of exposure to some vendors, including OnePlus (CVE-2017-5947) and Google (Nexus 6/6P devices) - CVE-2017-13174. sahara - ----- HWID: 0x0005f0e100000000 (MSM_ID:0x0005f0e1,OEM_ID:0x0000,MODEL_ID:0x0000) CPU detected: "MSM8996Pro" PK_HASH . For most devices the relevant UART points have already been documented online by fellow researchers/engineerings. Berbagai Masalah Vivo Y51L. 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). This feature is used by our Nokia 6 exploit, since we need to relocate the debugger during the SBL to ABOOT transition. To make any use of this mode, users must get hold of OEM-signed programmers, which seem to be publicly available for various such devices. 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. Did a quick search and found the location of the test points on the Redmi 7A (Click to view the image). Must be easily downloadable (no turbobits/dfiles and other adware), preferably a direct link; 2. Google has patched CVE-2017-13174 in the December 2017 Security Bullet-in. So breakpoints are simply placed by replacing instructions with undefined ones which cause the undefined instruction handler, that we hooked, to be executed. 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. * - Flashing 99% of, posiciones sexuales permitidas por la biblia, caramel recipe without corn syrup or candy thermometer, firehorse. Later, our UART output can be fed into IDA, using another IDA Python script, to mark the execution path. If emmc flash is used, remove battery, short DAT0 with gnd, connect battery, then remove short. EDL mode is entered by plugging the cable while having * and # pressed at the same time. 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. Its often named something like prog_*storage. In this part we extend the capabilities of firehorse even further, making it . 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. If it is in a bootloop or cannot enter the OS, move to the second method. There are no posts matching your filters. So, let's collect the knowledge base of the loaders in this thread. elf -MemoryName ufs -SetActivePartition 1 -x rawprogram0 exe emmcdl Although, Tool Studio eMMC Download Tool is a very sophisticated Qualcomm Android device service tools, it is very simple to use and very fast at completing the task EMMCDL is a command-line utility that allows all kinds of manipulation in EDL > format. And thus, there would be no chance of flashing the firmware to revive/unbrick the device. 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. CVE-2017 . 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. 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. 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. We're now entering a phase where fundamental things have to be understood. 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. XDA Developers was founded by developers, for developers. Home EMMC Files All Qualcomm Prog eMMC Firehose Programmer file Download. Let me start with my own current collection for today -. 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. Thank you for this!! Further updates on this thread will also be reflected at the special. JusttriedonaTA-1071(singleSIM),doesn'tworkeither. XML Hunting. Its 16-bit encoding is XXDE. Alcatel. However, thats not the case always. However,theOEMhashisexactlythesameastheTA-1059. because virtually any firehose file will work there. Seems like CAT is using generic HWID for 8909 devices We got very lucky with this. 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). 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. 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. A tag already exists with the provided branch name. You can Download and Use this file to remove Screen lock on Qualcomm Supports Devices, and Bypass FRP Google account on all Qualcomm Devices, Qualcomm Prog eMMC Firehose Programmer file Download, Lava V62 Benco FRP File Download (Bypass Google) by SPD Research Tool Latest Free, DarkRa1n iCloud Bypass Tool iOS 16 iOS 15 Download Free Latest, VNROM FILE Ramdisk Tool Download Windows Latest Version Free, Mina Ramdisk Bypass Tool V1.3 Download Latest Version for MAC Free, GSM Gaster Tool V4.0 Download Latest Passcode, Hello Screen Disable Device, OMH Mi Blu Relock Fixer Tool V1 Download Latest Version Free, iOS Factory Reset Tool V1 Download latest version Free, CICADA iTools V4.1 Download Latest Version Setup Free, Oppo A11s No Auth Loader Firehose File Download Free, Motorola G Stylus 5G EDL Firehose Programmer File Download Free. So if anyone has any tips on how to find a loader for it (or for other Android flip phones, for that matter), I would be interested. I have the firehose/programmer for the LG V60 ThinQ. 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. Remove libusb1 for windows (libusb0 only), fix reset command, Fix sahara id handling and memory dumping, MDM9x60 support. Butunfortunatelydoesn'tseemtowork. Some times, flashing the wrong file can also potentially corrupt the Android bootloader itself. ALEPH-2017029. We guess that the Boot ROM can only be obtained from the secure state (which anglers programmer runs under). Our next goal was to be able to use these primitives in order to execute code within the programmer itself. I dont think the mother board is receiving power as the battery is dead. Luckily for us, it turns out that most Android devices expose a UART point, that can be fed into a standard FTDI232. 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. It soon loads the digitally-signed SBL to internal memory (imem), and verifies its authenticity. Save my name, email, and website in this browser for the next time I comment. As soon as the command is entered, your phone will enter Emergency Download Mode. Rebooting into EDL can also happen from the Platform OS itself, if implemented, and if adb access is allowed, by running adb reboot edl. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Why and when would you need to use EDL Mode? 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. Tested on our Nexus 6P, trying to read from its PBL physical address (0xFC010000), instantly resulted in a system reboot. In this part we presented an arbitrary code execution attack against Firehose programmers. Research & Exploitation framework for, A couple of years ago, it is easy to unbrick a Xiaomi device through Emergency Download Mode (, Programming & Flashing. This device has an aarch32 leaked programmer. 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. For example, on OnePlus 5: Now that we can conveniently receive output from the device, were finally ready for our runtime research. P.S. This isn't strictly speaking a Bananahackers question (because it's about Android phones), but this is where I learned about EDL mode. In this part we described our debugging framework, that enabled us to further research the running environment. The following info was from the device that works with the programmer I attached, HWID: 0x009600e100000000 (MSM_ID:0x009600e1,OEM_ID:0x0000,MODEL_ID:0x0000), PK_HASH: 0xcc3153a80293939b90d02d3bf8b23e0292e452fef662c74998421adad42a380f, prog_emmc_firehose_8909_ddr[d96ada9cc47bec34c3af6a3b54d6a73466660dcb].mbn, Andy, thanks a lot for figuring out the non-standard XML response for Nokias, merged your changes back into the, Also, if you didn't notice, we also already have the 800 Tough firehose in our, https://cloud.disroot.org/s/HzxB6YM2wRFPpWT/download, http://forum.gsmhosting.com/vbb/f296/nokia-8110-4g-full-support-infinity-qlm-1-16-a-2574130/, http://dl1.infinity-box.com/00/pub.php?dir=software/, http://edl.bananahackers.net/loaders/0x000940e100420050.mbn, https://groups.google.com/d/topic/bananahackers/T2RmKKGvGNI/unsubscribe, https://groups.google.com/d/msgid/bananahackers/3c9cf64a-710b-4f36-9090-7a00bded4a99n%40googlegroups.com. To defeat that, we devised a ROP chain that disables the MMU itself! In the previous part we explained how we gained code execution in the context of the Firehose programmer. When in this mode, the device identifies itself as Qualcomm HS-USB QDLoader 9008 over a USB connection. This very poor throughput is due to the fact that each poke only allows uploading 8 bytes (encoded as 16 bytes) at a time, with 499 pokes per XML. Before that, we did some preliminary analysis of the MSM8937/MSM8917 PBL, in order to understand its layout in a high-level perspective. In fact, thats one of the very common mistakes that users make when their device is bricked. Since their handling code is common, we can only guess that there exist some compilation flag that is kept enabled by the affected OEMs. To achieve code execution within the programmer, we hoped to find an writable and executable memory page, which we will load our code into, and then replace some stored LR in the execution stack to hijack the control flow. wade dominguez partner, Our flashed data did not remain in memory need a programmer abuse undefined instruction exceptions UART point, that knowledge. & Exploitation framework for Qualcomm EDL Firehose programmers go way beyond partition.!
