There are no posts matching your filters. 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. * - Flashing 99% of, posiciones sexuales permitidas por la biblia, caramel recipe without corn syrup or candy thermometer, firehorse. 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. CVE-2017 . Exploiting Qualcomm EDL Programmers (4): Runtime Debugger. Our first target device was Nokia 6, that includes an MSM8937 SoC. the Egg). On Linux or macOS: Launch the Terminal and change its directory to the platform-tools folder using the cd command. We then present our exploit framework, firehorse, which implements a runtime debugger for firehose programmers (Part 4). 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. 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. To defeat that, we devised a ROP chain that disables the MMU itself! Rebooting into EDL can also happen from the Platform OS itself, if implemented, and if adb access is allowed, by running adb reboot edl. 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. 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). Exploiting Qualcomm EDL Programmers (2): Storage-based Attacks & Rooting Exploiting Qualcomm EDL Programmers (3): Memory-based Attacks & PBL Extraction Exploiting Qualcomm EDL Programmers (4): Runtime Debugger Exploiting Qualcomm EDL Programmers (5): Breaking Nokia 6's Secure Boot Usage Prerequisites To use this tool you'll need: Additional license limitations: No use in commercial products without prior permit. 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. XML Hunting. Qualcomm Firehose Programmer file Collection: Download Prog_firehose files for All Qualcomm SoC. Executing this chain, we managed to leak the TTBR0 register into a controlled memory address without crashing the device (by reconstructing the stack and returning to the original caller). In this part we described our debugging framework, that enabled us to further research the running environment. 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). In order to further understand the memory layout of our devices, we dumped and parsed their page tables. 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. In order to tackle that, we abused the Firehose protocol in the following ways: Egg Hunting. firehorse. In this mode, the device identifies itself as Qualcomm HS-USB 9008 through USB. (Nexus 6P required root with access to the sysfs context, see our vulnerability report for more details). EDL is implemented by the PBL. Finding the address of the execution stack. In the previous part we explained how we gained code execution in the context of the Firehose programmer. 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. We believe other PBLs are not that different. Connect the phone to your PC while its in Fastboot mode. As one can see, there are such pages already available for us to abuse. Credits & Activations. Collection Of All Qualcomm EMMC Programmer Files Today I will share you all Qualcomm EMMC Filehose Programmer file for Certain Devices. (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.). The next part is solely dedicated for our runtime debugger, which we implemented on top of the building blocks presented in this part. You signed in with another tab or window. Meaninganyworkingloader,willworkonbothofthem(andhopefullyfortheotheronesaswell). 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. This device has an aarch32 leaked programmer. 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. Debuggers that choose this approach (and not for example, emulate the original instruction while leaving the breakpoint intact), must conduct a single-step in order to place the breakpoint once again. 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. 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. It looks like we were having a different problem with the Schok Classic, not a fused loader issue. When in this mode, the device identifies itself as Qualcomm HS-USB QDLoader 9008 over a USB connection. 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. It can be found online fairly easily though. (Later we discovered that this was not necessary because we also statically found that address in the PBL & Programmer binaries.) emmc Programs File. Not all Qualcomm devices support booting into EDL via ADB or Fastboot as shown above. In the case of Qualcomm , these programmers are referred to as " firehose >" binaries. 2021. ), youll need to use the test point method. The signed certificates have a root certificate anchored in hardware. We presented our research framework, firehorse, and showed how we extracted the PBL of various SoCs. Thank you for this!! 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. 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. The only thing we need to take care of is copying the original stack and relocating absolute stack address. The extracted platform-tools folder will contain ADB and other binaries youd need. I retrieved the file from another device which reports exactly the same HWID and PK_HASH as yours and I found this group by complete accident. Each of these routines plays an important role in the operation of the PBL. The EDL mode itself implements the Qualcomm Sahara protocol, which accepts an OEM-digitally-signed programmer (an ELF binary in recent devices, MBN in older ones) over USB, that acts as an SBL. For details on how to get into EDL, please see our blog post. 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. initramfs is a cpio (gzipped) archive that gets loaded into rootfs (a RAM filesystem mounted at /) during the Linux kernel initialization. Your phone should now reboot and enter EDL mode. 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. As open source tool (for Linux) that implements the Qualcomm Sahara and Firehose protocols has been developed by Linaro, and can be used for program (or unbrick) MSM based devices, such as Dragonboard 410c or Dragonboard 820c. Yes, your device needs to be sufficiently charged to enter EDL mode. Do you have Nokia 2720 flip mbn Or Nokia 800 tough mbn? (TheyactuallybothhaveadifferentOEMhash,whichprobablymeanstheyaredifferentlysigned,no?). We must be at any moment prepared for organized resistance against the pressure from anyone trying to take away what's ours. JavaScript is disabled. For Oneplus 6T, enter #801# on dialpad, set Engineer Mode and Serial to on and try : Published under MIT license Research & Exploitation framework for Qualcomm EDL Firehose programmers, By Roee Hay (@roeehay) & Noam Hadad, Aleph Reseserch, HCL Technologies. January 22, 2018 * QPSIIR-909. Save my name, email, and website in this browser for the next time I comment. . 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). 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). To have a better understanding, please take a look at the figures below. You can Download and Use this file to remove Screen lock on Qualcomm Supports Devices, and Bypass FRP Google account on all Qualcomm Devices. 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. 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. When shorted during the boot, these test points basically divert the Primary Bootloader (PBL) to execute EDL mode. This isn't strictly speaking a Bananahackers question (because it's about Android phones), but this is where I learned about EDL mode. 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. We often like to refer to this device state as a Hard-brick. 5 A tag already exists with the provided branch name. Further updates on this thread will also be reflected at the special. You must log in or register to reply here. 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. Research & Exploitation of Qualcomm EDL Firehose Programmers: From PBL (Boot ROM) Extraction, Research & Analysis to Secure Boot Bypass in Nokia 6. . 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. Whether that file works for the Schok won't tell you much, We constructed a similar chain for OnePlus 5, however, to keep the device in a working state we had to restore some registers to their original value before the execution of the chain. Our next goal was to be able to use these primitives in order to execute code within the programmer itself. P.S. Modern such programmers implement the Firehose protocol. The availability of these test points varies from device to device, even if they are from the same OEM. In addition, rebooting into EDL by software is done by asserting the LSB of the 0x193D100 register (also known as tcsr-boot-misc-detect) 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). I've discovered a few that are unfused (Orbic Journey, Coolpad Snap, and Schok Classic). Modern such programmers implement the Firehose protocol, analyzed next. 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). We reported this kind of exposure to some vendors, including OnePlus (CVE-2017-5947) and Google (Nexus 6/6P devices) - CVE-2017-13174. This special mode of operation is also commonly used by power users to unbrick their devices. 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). Exploiting Qualcomm EDL Programmers (1): Gaining Access & PBL Internals, Exploiting Qualcomm EDL Programmers (2): Storage-based Attacks & Rooting, Exploiting Qualcomm EDL Programmers (3): Memory-based Attacks & PBL Extraction, Exploiting Qualcomm EDL Programmers (4): Runtime Debugger, Exploiting Qualcomm EDL Programmers (5): Breaking Nokia 6's Secure Boot, Qualcomm Product Support Tools (QPST - we used version 2.7.437 running on a windows 10 machine), A Cross compiler to build the payload for the devices (we used, set COM to whatever com port the device is connnected to, set FH_LOADER with a path to the fh_loader.exe in the QPST\bin directory, set SAHARA_SERVER with a path to the QSaharaServer.exe in the QPST\bin directory. 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. I have the firehose/programmer for the LG V60 ThinQ. For example, here is the UART TX point for OnePlus 5: On some devices UART is not initialized by the programmers. these programmers are often leaked from OEM device repair labs. 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. Why not reconstruct the 32-bit page table? Since the programmer replaces the SBL itself, we expect that it runs in very high privileges (hopefully EL3), an assumption we will later be able to confirm/disprove once code execution is achieved. Are you sure you want to create this branch? In addition, OnePlus 5s programmers runs in EL1, so we used SCTLR_EL1 instead of the EL3 counterpart. If emmc flash is used, remove battery, short DAT0 with gnd, connect battery, then remove short. sbl maintains the SBL contextual data, where its first field points to a copy of pbl2sbl_data. 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). Some of them will get our coverage throughout this series of blog posts. To start working with a specific device in EDL , you need a programmer . Analyzing several Firehose programmers binaries quickly reveals that this is an XML over USB protocol. you can check other tutorialshere to help. A working 8110 4G firehose found, should be compatible with any version. most programmers use firehose to communicate with a phone in edl mode, which is what the researchers exploited to gain full device control. It soon loads the digitally-signed SBL to internal memory (imem), and verifies its authenticity. Let me start with my own current collection for today -. Thats exactly when youd need to use EDL mode. noidodroid Senior Member. The reset handler (address 0x100094) of the PBL roughly looks as follows (some pseudo-code was omitted for readability). 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. Note: use at own risk How to use: use with supported Box use with qfil Downloads: 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 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. So, let's collect the knowledge base of the loaders in this thread. I know that some of them must work at least for one 8110 version. 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). So can you configure a firehose for nokia 2720/800? We then continued by exploring storage-based attacks.
