MTKClient

Logo

Just some mtk tool for exploitation, reading/writing flash and doing crazy stuff. For windows, you need to install the stock mtk port and the usbdk driver (see instructions below). For linux, a patched kernel is only needed when using old kamakiri (see Setup folder) (except for read/write flash).

Once the mtk script is running, boot into brom mode by powering off device, press and hold either vol up + power or vol down + power and connect the phone. Once detected by the tool, release the buttons.

MT6781, MT6789, MT6855, MT6886, MT6895, MT6983, MT8985

  • These chipsets use a new protocol called V6 and the bootrom is patched, thus you need a valid da via --loader option.
  • On some devices, preloader is deactivated, but you still use it by running "adb reboot edl".
  • This only works with UNFUSED devices currently.
  • For all devices with DAA, SLA and Remote-Auth activated no public solution currently exists (for various reasons).

Get latest UsbDk 64-Bit

  • Install normal MTK Serial Port driver (or use default Windows COM Port one, make sure no exclamation is seen)
  • Get usbdk installer (.msi) from here and install it
  • Test on device connect using "UsbDkController -n" if you see a device with 0x0E8D 0x0003
  • Works fine under Windows 10 and 11 :D

Building wheel issues (creds to @Oyoh-Edmond)

Download and Install the Build Tools:
Go to the Visual Studio Build Tools [download](https://visualstudio.microsoft.com/visual-cpp-build-tools) page.
Download the installer and run it.
Select the Necessary Workloads:
In the installer, select the "Desktop development with C++" workload.
Ensure that the "MSVC v142 - VS 2019 C++ x64/x86 build tools" (or later) component is selected.
You can also check "Windows 10 SDK" if it’s not already selected.
Complete the Installation:
Click on the "Install" button to begin the installation.
Follow the prompts to complete the installation.
Restart your computer if required.

Use kamakiri (optional, only needed for mt6260 or older)

  • For linux (kamakiri attack), you need to recompile your linux kernel using this kernel patch :
sudo apt-get install build-essential libncurses-dev bison flex libssl-dev libelf-dev libdw-dev
git clone https://git.kernel.org/pub/scm/devel/pahole/pahole.git
cd pahole && mkdir build && cd build && cmake .. && make && sudo make install
sudo mv /usr/local/libdwarves* /usr/local/lib/ && sudo ldconfig
wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-`uname -r`.tar.xz
tar xvf linux-`uname -r`.tar.xz
cd linux-`uname -r`
patch -p1 < ../Setup/kernelpatches/disable-usb-checks-5.10.patch
cp -v /boot/config-$(uname -r) .config
make menuconfig
make
sudo make modules_install 
sudo make install
  • These aren't needed for current ubuntu (as make install will do, just for reference):
sudo update-initramfs -c -k `uname -r`
sudo update-grub

See Setup/kernels for ready-to-use kernel setups

  • Reboot
sudo reboot

Usage

Using MTKTools via the graphical user interface:

For the 'basics' you can use the GUI interface. This supports dumping partitions or the full flash for now. Run the following command:

python mtk_gui.py

Using stock mtk functionality without exploits :

python mtk.py --stock

Run multiple commands

python mtk.py script run.example

See the file "run.example" on how to structure the script file

Root the phone (Tested with android 9 - 12)

  1. Dump boot and vbmeta
python mtk.py r boot,vbmeta boot.img,vbmeta.img
  1. Reboot the phone
python mtk.py reset
  1. Download patched magisk for mtk: Download latest Magisk here

  2. Install on target phone

  • you need to enable usb-debugging via Settings/About phone/Version, Tap 7x on build number
  • Go to Settings/Additional settings/Developer options, enable "OEM unlock" and "USB Debugging"
  • Install magisk apk
adb install app-release.apk
  • accept auth rsa request on mobile screen of course to allow adb connection
  1. Upload boot to /sdcard/Download
adb push boot.img /sdcard/Download
  1. Start magisk, tap on Install, select boot.img from /sdcard/Download, then:
adb pull /sdcard/Download/[displayed magisk patched boot filename here]
mv [displayed magisk patched boot filename here] boot.patched
  1. Do the steps needed in section "Unlock bootloader below"

  2. Flash magisk-patched boot and empty vbmeta

python mtk.py w boot,vbmeta boot.patched,vbmeta.img.empty
  1. Reboot the phone
python mtk.py reset
  1. Disconnect usb cable and enjoy your rooted phone :)

Boot to meta mode via payload

Example:

python mtk.py payload --metamode FASTBOOT

Read efuses

Example:

python mtk.py da efuse

Unlock bootloader

  1. Erase metadata and userdata (and md_udc if existing):
python mtk.py e metadata,userdata,md_udc
  1. Unlock bootloader:
python mtk.py da seccfg unlock

for relocking use:

python mtk.py da seccfg lock
  1. Reboot the phone:
python mtk.py reset

and disconnect usb cable to let the phone reboot.

If you are getting a dm-verity error on Android 11, just press the power button, then the device should boot and show a yellow warning about unlocked bootloader and then the device should boot within 5 seconds.

Dump brom

  • Device has to be in bootrom mode, or da mode has to be crashed to enter damode
  • if no option is given, either kamakiri or da will be used (da for insecure targets)
  • if "kamakiri" is used as an option, kamakiri is enforced
  • Valid options are : "kamakiri" (via usb_ctrl_handler attack), "amonet" (via gcpu) and "hashimoto" (via cqdma)
