[Tutorial] How to unlock Motorola MediaTek bootloader using the Val Protocol
13-08-2026, 01:14 AM
The Valeria Protocol enables you to unlock your MediaTek-powered Motorola device's bootloader using a Fastboot and LK cert exploit. It patches your stock LK.img, then generates a key which you can use to unlock the bootloader via the fastboot oem unlock UNLOCK_KEY command after you flash the patched and signed LK.img.
Requirements
- Install Python3 on your PC
- Enable OEM Unlocking on the phone
- Download your device's firmware and extract the lk.img
- Boot your device into fastboot and get its serial number (referred to as SERIAL_NUMBER) using:
Code:fastboot getvar serialno
Steps to unlock a Motorola MediaTek bootloader using the Val Protocol
- Clone the repo and install dependencies
Code:git clone https://github.com/Maikyxd/val-protocol.git cd val-protocol python -m pip install -r requirements.txt python -m pip install git+https://github.com/R0rt1z2/liblk
- Copy the lk.img into the val-protocol directory
- Patch the lk.img with the serial-based unlock preset
Code:python lk_auto_patch.py lk.img -o lk.unlock-serial.img --preset unlock-serial --key-token-secret "Valeria"
A file named lk.unlock-serial.img should be generated
- Generate a key for your serial number
Code:python lk_keygen.py --secret "Valeria" --serialno "SERIAL_NUMBER" --count 1
An example output is:
Quote:Mode : key-token
Secret : 'Valeria'
Device : 'SERIAL_NUMBER' (runtime-serial)
Alphabet: alnum
Const : 2d5a461414431b504e5f
XXXXXXXX <-- Your UNLOCK_KEY
- Flash the generated lk.unlock-serial.img in fastboot
Code:fastboot flash lk lk.unlock-serial.img
- Unlock the bootloader
Code:fastboot oem unlock UNLOCK_KEY
Important Notice
- You can use a custom key token secret; we just stuck to Valeria in this guide
- If you encounter "Code validation failure", then manually type your UNLOCK_KEY instead of copy-pasting it.
