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.

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:

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 examples/run.example

or

python mtk.py multi "cmd1;cmd2"

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

2. Reboot the phone

python mtk.py reset

3. Download patched magisk for mtk: Download latest Magisk here

4. 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

5. Upload boot to /sdcard/Download

adb push boot.img /sdcard/Download

6. 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

7. Do the steps needed in section "Unlock bootloader below"

8. Flash magisk-patched boot and disable verity + verification on vbmeta

python mtk.py da vbmeta 3
python mtk.py w boot boot.patched

9. Reboot the phone

python mtk.py reset

10. Disconnect usb cable and enjoy your rooted phone :)

Boot to meta mode via payload

Example:

python mtk.py payload --metamode FASTBOOT

Dump preloader

mtk.py r preloader preloader.bin --parttype boot1

Dump serialnumber / special partition

mtk.py r preloader preloader.bin --parttype boot2

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

2. Unlock bootloader:

python mtk.py da seccfg unlock

for relocking use:

python mtk.py da seccfg lock

3. 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 preloader

• Device has to be in bootrom mode and preloader has to be intact on the device

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

I have issues ....... please send logs and full console details !

• Run the mtk tool with --debugmode. Log will be written to log.txt (hopefully)

Rules / Infos

Chip details / configs
