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. Ok, let's forget about 2720 for now. 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. Some devices have boot config resistors, if you find the right ones you may enforce booting to sdcard instead of flash. 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. . As mentioned above, modern EDL programmers implement the Qualcomm Firehose protocol. Phones from Xiaomi and Nokia are more susceptible to this method. Updated on, P.S. Read our comment policy fully before posting a comment. Having a short glimpse at these tags is sufficient to realize that Firehose programmers go way beyond partition flashing. sahara - ----- HWID: 0x0005f0e100000000 (MSM_ID:0x0005f0e1,OEM_ID:0x0000,MODEL_ID:0x0000) CPU detected: "MSM8996Pro" PK_HASH . Sorry for the false alarm. Sorry, couldn't talk to Sahara, please reboot the device ! It may not display this or other websites correctly. As one can see, the relevant tag that instructs the programmer to flash a new image is program. In Part 3 we exploit a hidden functionality of Firehose programmers in order to execute code with highest privileges (EL3) in some devices, allowing us, for example, to dump the Boot ROM (PBL) of various SoCs. Just plug in your device to the wall charger for at least 30-40 minutes so that it gets sufficiently charged. Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. Improved streaming stuff, Qualcomm Sahara / Firehose Attack Client / Diag Tools. For most devices the relevant UART points have already been documented online by fellow researchers/engineerings. 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. 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. So, the file is indeed correct but it's deliberately corrupted. In addition, rebooting into EDL by software is done by asserting the LSB of the 0x193D100 register (also known as tcsr-boot-misc-detect) noidodroid Senior Member. It's already in the above archive. 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. the Egg). Which version of 8110 do you have? Analyzing several programmers binaries quickly reveals that commands are passed through XMLs (over USB). Android phones and tablets equipped with Qualcomm chipset contain a special boot mode which could be used force-flash firmware files for the purpose of unbricking or restoring the stock ROM. Did a quick search and found the location of the test points on the Redmi 7A (Click to view the image).

"/>. 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. For instance, the following XML makes the programmer flash a new Secondary Bootloader (SBL) image (also transfered through USB). Thats it! Berbagai Masalah Vivo Y51L. Receive the freshest Android & development news right in your inbox! 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. you can check other tutorialshere to help. You will need to open the ufs die and short the clk line on boot, some boards have special test points for that. At the beginning we naively implemented breakpoints for 2-byte Thumb instructions with 16-bit long invalid instructions (0xFFFF), however we soon realized it was problematic as they might actually result in valid 32-bit instructions, depending on the adjacent word. But newer Schok Classic phones seem to have a fused loader. This error is often a false-positive and can be ignored as your device will still enter EDL. When in this mode, the device identifies itself as Qualcomm HS-USB QDLoader 9008 over a USB connection. 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. So, let's collect the knowledge base of the loaders in this thread. the last gadget will return to the original caller, and the device will keep processing Firehose commands. Digging into the programmers code (Xiaomi Note 5A ugglite aarch32 programmer in this case) shows that its actually an extended SBL of some sort. Qualcomm Sahara / Firehose Client (c) B.Kerler 2018-2019. All of these guides make use of Emergency Download Mode (EDL), an alternate boot-mode of the Qualcomm Boot ROM (Primary Bootloader). Thank you for this!! 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. Does this mean, the firehose should work? Looking to work with some programmers on getting some development going on this. Some devices have an XBL (eXtensible Bootloader) instead of an SBL. Ive managed to fix a bootloop on my Mi A2. Collection Of All Qualcomm EMMC Programmer Files Today I will share you all Qualcomm EMMC Filehose Programmer file for Certain Devices. By dumping that range using firehorse, we got the following results: We certainly have something here!

In this mode, the device identifies itself as Qualcomm HS-USB 9008 through USB. If emmc flash is used, remove battery, short DAT0 with gnd, connect battery, then remove short. 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. 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. Modern such programmers implement the Firehose protocol, analyzed next. 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. Analyzing several programmers' binaries quickly reveals that commands are passed through XMLs (over USB). Here is the Jiophone 2 firehose programmer. 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). A natural continuation of this research is gaining arbitrary code execution in the context of the programmer itself. 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, is implemented by the Primary Bootloader (PBL), allows to escape from the unfortunate situation where the second stage bootloader (stored in flash) is damaged. During this process, EDL implements the Firehose/Sahara protocol and acts as a Secondary Bootloader to accept commands for flashing. For example, here is the UART TX point for OnePlus 5: On some devices UART is not initialized by the programmers. It can be found online fairly easily though. Google has patched CVE-2017-13174 in the December 2017 Security Bullet-in. 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. 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. I know that some of them must work at least for one 8110 version. The source is pretty much verified. but edl mode is good choice, you should be able to wipe data and frp . Some SBLs may also reboot into EDL if they fail to verify that images they are in charge of loading. r"C:\Program Files (x86)\Qualcomm\QPST437\bin\fh_loader.exe", r"C:\Program Files (x86)\Qualcomm\QPST437\bin\QSaharaServer.exe". Some of these powerful capabilities are covered extensively throughout the next parts. 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 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. Which, in our case, is the set of Qualcomm EDL programmer/loader binaries of Firehose standard. Mar 22, 2021 View. 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. 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. 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. For Nokia 6 (aarch32), for example, we get the following UART log, that indicates we are in EL3: The Nexus 6P (angler) aarch64 programmer also runs in EL3: OnePlus 5s programmer, on the other hand, runs in EL1: We can see that the most recent programmer has the least privilege level, a good sign from Qualcomm. No, that requires knowledge of the private signature keys. 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). It seems like EDL mode is only available for a split second and then turn off. 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. Our next goal was to be able to use these primitives in order to execute code within the programmer itself. Finding the address of the execution stack. GADGET 2: Similarly to the aarch32 case, we copy the original stack s.t. We also read the SCR.NS register (if possible) in order to find if we ran in Secure state. In this part we presented an arbitrary code execution attack against Firehose programmers. There are no posts matching your filters. 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. In the case of Qualcomm , these programmers are referred to as " firehose >" binaries. The extracted platform-tools folder will contain ADB and other binaries youd need. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. 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 . So, I know the only file from this archive for sure: Filename: prog_emmc_firehose_8909_alcF.mbn. You must log in or register to reply here. ABOOT then verifies the authenticity of the boot or recovery images, loads the Linux kernel and initramfs from the boot or recovery images. 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. The figure on the right shows the boot process when EDL mode is executed. JusttriedonaTA-1071(singleSIM),doesn'tworkeither. One significant problem we encountered during the development of the debugger is that upload rate over poke is extremely slow. 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. Concretely, in the next chapters we will use and continue the research presented here, to develop: 73C51DE96B5F6F0EE44E40EEBC671322071BC00D705EEBDD7C60705A1AD11248, 74F3DE78AB5CD12EC2E77E35B8D96BD8597D6B00C2BA519C68BE72EA40E0EB79, D18EF172D0D45AACC294212A45FBA91D8A8431CC686B164C6F0E522D476735E9, 9B3184613D694EA24D3BEEBA6944FDB64196FEA7056C833D38D2EF683FD96E9B, 30758B3E0D2E47B19EBCAC1F0A66B545960784AD6D428A2FE3C70E3934C29C7A, 8D417EF2B7F102A17C2715710ABD76B16CBCE8A8FCEB9E9803733E731030176B, 02FFDAA49CF25F7FF287CAB82DA0E4F943CABF6E6A4BFE31C3198D1C2CFA1185, EEF93D29E4EDDA26CCE493B859E22161853439DE7B2151A47DAFE3068EE43ABE, A1B7EB81C61525D6819916847E02E9AE5031BF163D246895780BD0E3F786C7EE, 97EFF4D4111DD90523F6182E05650298B7AE803F0EC36F69A643C031399D8D13, C34EC1FDDFAC05D8F63EED3EE90C8E6983FE2B0E4B2837B30D8619A29633649C, 63A47E46A664CCD1244A36535D10CA0B97B50B510BD481252F786177197C3C44, 964B5C486B200AA6462733A682F9CEAD3EBFAD555CE2FF3622FEA8B279B006EE, 71C4F97535893BA7A3177320143AC94DB4C6584544C01B61860ACA80A477D4C9, CB06DECBE7B1C47D10C97AE815D4FB2A06D62983738D383ED69B25630C394DED, A27232BF1383BB765937AEA1EBDEE8079B8A453F3982B46F5E7096C373D18BB3, 3FDAF99FC506A42FCBC649B7B46D9BB8DD32AEABA4B56C920B45E93A4A7080EA, 48741756201674EB88C580DF1FDB06C7B823DC95B3FC89588A84A495E815FBD4, 8483423802d7f01bf1043365c855885b0eea193bf32ed25041a347bc80c32d6b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nd thus, there would be no chance of flashing the firmware to revive/unbrick the device. 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.
