Only unencrypted MSM8909-compatible format (the binary contents must start with ELF or "data ddc" signature). You can Download and Use this file to remove Screen lock on Qualcomm Supports Devices, and Bypass FRP Google account on all Qualcomm Devices. Alcatel Onetouch Idol 3. But newer Schok Classic phones seem to have a fused loader. You can use it for multi-purpose on your Qualcomm powered phone such as Remove Screen lock, Flash Firmware, Remove FRP, Repair IMEI, also fix any type of error by the help of QPST/Qfil tool or any other third party repair tool, So, download basic firmware file or Prog EMMC MBN File from below. The first part presents some internals of the PBL, EDL, Qualcomm Sahara and programmers, focusing on Firehose. 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). 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). You also wouldnt want your device to turn off while youre flashing the firmware, which could lead to unexpected results. Before we do so, we need to somehow get output from the device. One significant problem we encountered during the development of the debugger is that upload rate over poke is extremely slow. I have the firehose/programmer for the LG V60 ThinQ. Our first target device was Nokia 6, that includes an MSM8937 SoC. 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: Please empty this comment field to prove you're human. Finally, enter the following command in PowerShell to boot your phone into EDL mode. chargers). Later, the PBL will actually skip the SBL image loading, and go into EDL mode. Looking to work with some programmers on getting some development going on this. Read our comment policy fully before posting a comment. I've discovered a few that are unfused (Orbic Journey, Coolpad Snap, and Schok Classic). My proposed format is the following: - exact model name. While the reason of their public availability is unknown, our best guess is that In the previous part we explained how we gained code execution in the context of the Firehose programmer. By Roee Hay & Noam Hadad. Before that, we did some preliminary analysis of the MSM8937/MSM8917 PBL, in order to understand its layout in a high-level perspective. Berbagai Masalah Vivo Y51L. Qualcomm Sahara / Firehose Client (c) B.Kerler 2018-2019. After that select the programmer file prog_emmc_firehose_8917_ddrMBN. Therefore, the address of the next gadget (0x8008D38) should be written to ORIGINAL_SP + 4 + 0x118 + 20 (R4-R8). In addition, rebooting into EDL by software is done by asserting the LSB of the 0x193D100 register (also known as tcsr-boot-misc-detect) MSM (Qualcomms SoC)-based devices, contain a special mode of operation - Emergency Download Mode (EDL). Since the PBL is a ROM resident, EDL cannot be corrupted by software. As we witnessed in Part 1, oddly enough Firehose programmers implement the peek and poke XML tags, which according to our correspondence with Qualcomm, are customizations set by OEMs QPSIIR-909. Our XML Hunter searches the relevant memory for such pokes, and decodes the data, contained in the supplied attribute. (Later we discovered that this was not necessary because we also statically found that address in the PBL & Programmer binaries.) After that click on the select programmers path to browse and select the file. It can be found online fairly easily though. Some SBLs may also reboot into EDL if they fail to verify that images they are in charge of loading. In this post, you will learn what EDL mode is, and why and when youd need to use it. Having a short glimpse at these tags is sufficient to realize that Firehose programmers go way beyond partition flashing. 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. In order to tackle that, we abused the Firehose protocol in the following ways: Egg Hunting. (Nexus 6P required root with access to the sysfs context, see our vulnerability report for more details). For a better experience, please enable JavaScript in your browser before proceeding. In this part we extend the capabilities of firehorse even further, making it . Knowing the memory-layout of the programmers, and the running exception level, we started peeking around. It soon loads the digitally-signed SBL to internal memory (imem), and verifies its authenticity. As mentioned above, modern EDL programmers implement the Qualcomm Firehose protocol. 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. 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. The first part presents some internals of the PBL, GitHub Stars program. 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 . 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. Finding the vector base address is a trivial task, as it can be done either statically, by reverse-engineering the programmers code, or even better - in runtime. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. And thus, there would be no chance of flashing the firmware to revive/unbrick the device. 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. This error is often a false-positive and can be ignored as your device will still enter EDL. 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. 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. Other devices, such as the OnePlus family, test a hardware key combination upon boot to achieve a similar behavior. 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. However, thats not the case always. 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. Rahul, most (if not all) Xiaomi phones would need the third method to get into EDL mode. A defining property of debuggers is to be able to place breakpoints. Thats it! 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. We also read the SCR.NS register (if possible) in order to find if we ran in Secure state. 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. Receive the freshest Android & development news right in your inbox! Similarly, in aarch64 we have the VBAR_ELx register (for each exception level above 0). Research & Exploitation framework for Qualcomm EDL Firehose programmers. most programmers use firehose to communicate with a phone in edl mode, which is what the researchers exploited to gain full device control. Xiaomi) also publish them on their official forums. 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 Collection Of All Qualcomm EMMC Programmer Files Today I will share you all Qualcomm EMMC Filehose Programmer file for Certain Devices. Research & Exploitation framework for Qualcomm EDL Firehose programmers, By Roee Hay (@roeehay) & Noam Hadad, Aleph Reseserch, HCL Technologies. A natural continuation of this research is gaining arbitrary code execution in the context of the programmer itself. the last gadget will return to the original caller, and the device will keep processing Firehose commands. Connect the phone to your PC while its in Fastboot mode. 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. 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. We then continued by exploring storage-based attacks. So, let's collect the knowledge base of the loaders in this thread. 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. Comment for robots There are no posts matching your filters. 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). Its often named something like prog_*storage. All of these guides make use of Emergency Download Mode (EDL), an alternate boot-mode of the Qualcomm Boot ROM (Primary Bootloader). these programmers are often leaked from OEM device repair labs. (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.). 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 (. Individual loaders must have .mbn or .bin extension, archives should be preferably zip or 7z, no rar; 3. because virtually any firehose file will work there. So, let's collect the knowledge base of the loaders in this thread. 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. In order to further understand the memory layout of our devices, we dumped and parsed their page tables. 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. 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 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. 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. but edl mode is good choice, you should be able to wipe data and frp . Anyway, peek and poke are the holy grail of primitives that attackers creatively gain by exploiting vulnerabilities. As for aarch64, we also have preliminary support for working with the MMU enabled, by controlling the relevant page table entries. Without which, booting into modes like Fastboot or Download modes wouldnt be possible. 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. We end with a Nokia 6/5 and old Xiaomi SBLs), and reboot into EDL if these pins are shortened. As for the other devices we posses, that have aarch64 programmers, ROP-based exploitation was indeed needed, as no writable/executable pages were found, due to probably the employment of SCTLR.WXN, that disables execution on any writable page, regardless of its NX bit. ), 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. One possible explanation for their existence is that they are old entries from the APPS PBL (which indeed sets TTBR0 to 0xFE800000). 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). We then present our exploit framework, firehorse, which implements a runtime debugger for firehose programmers (Part 4). 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. Are you sure you want to create this branch? We could have not dumped everything because then we would risk in device hangs, reboots, etc, since some locations are not of the RAM. sahara - ----- HWID: 0x0005f0e100000000 (MSM_ID:0x0005f0e1,OEM_ID:0x0000,MODEL_ID:0x0000) CPU detected: "MSM8996Pro" PK_HASH .
