mtkclient

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.

Installation

Use Re LiveDVD (everything ready to go, based on Ubuntu):

Download Re Live DVD V2 User: livedvd, Password:livedvd

Install

Linux - (Ubuntu recommended, no patched kernel needed except for kamakiri)

Install python >=3.8, git and other deps

sudo apt install python3 git libusb1.0

Grab files

git clone https://github.com/bkerler/mtkclient
cd mtkclient
pip3 install -r requirements.txt
python3 setup.py build
python3 setup.py install

Install rules

sudo usermod -a -G plugdev $USER
sudo usermod -a -G dialout $USER
sudo cp Setup/Linux/*.rules /etc/udev/rules.d
sudo udevadm control -R

Make sure to reboot after adding the user to dialout/plugdev.

Windows

Install python + git

  • Install python 3.9 and git
  • If you install python from microsoft store, "python setup.py install" will fail, but that step isn't required.
  • WIN+R cmd

Grab files and install

git clone https://github.com/bkerler/mtkclient
cd mtkclient
pip3 install -r requirements.txt

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

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

Root the phone (Tested with android 9 - 12)

  1. Dump boot and vbmeta
python mtk r boot,vbmeta boot.img,vbmeta.img
  1. Reboot the phone
python mtk reset

  1. Download patched magisk for mtk: Download (here)[https://raw.githubusercontent.com/vvb2060/magisk_files/44ca9ed38c29e22fa276698f6c03bc1168df2c10/app-release.apk]

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

Unlock bootloader

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

for relocking use:

python mtk xflash seccfg lock
  1. Reboot the phone:
python mtk 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.

Read flash

Dump boot partition to filename boot.bin via preloader

python mtk r boot boot.bin

Dump boot partition to filename boot.bin via bootrom

python mtk r boot boot.bin [--preloader=Loader/Preloader/your_device_preloader.bin]

Read full flash to filename flash.bin (use --preloader for brom)

python mtk rf flash.bin

Dump all partitions to directory "out". (use --preloader for brom)

python mtk rl out

Show gpt (use --preloader for brom)

python mtk printgpt

Write flash

(use --preloader for brom)

Write filename boot.bin to boot partition

python mtk w boot boot.bin

Write filename flash.bin as full flash (currently only works in da mode)

python mtk wf flash.bin

Write all files in directory "out" to the flash partitions

python mtk wl out

Erase flash

Erase boot partition

python mtk e boot

Erase boot sectors

python mtk es boot [sector count]

XFlash commands (only available via XFlash da, not legacy da for now):

Peek memory

python mtk xflash peek [addr in hex] [length in hex] [optional: -filename filename.bin for reading to file]

Poke memory

python mtk xflash peek [addr in hex] [data as hexstring or -filename for reading from file]

Bypass SLA, DAA and SBC (using generic_patcher_payload)

python mtk payload If you want to use SP Flash tool afterwards, make sure you select "UART" in the settings, not "USB".

Dump preloader

  • Device has to be in bootrom mode and preloader has to be intact on the device
python mtk dumppreloader [--ptype=["amonet","kamakiri","kamakiri2","hashimoto"]] [--filename=preloader.bin]

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)
python mtk dumpbrom --ptype=["amonet","kamakiri","hashimoto"] [--filename=brom.bin]

For to dump unknown bootroms, use brute option :

python mtk brute

If it's successful, please add an issue over here and append the bootrom in order to add full support.
