This is a tool to lock/unlock a Unisoc / Spreadtrum (SPD) Android bootloader using its Identifier Token.
It is a port of a WebUSB based tool ([0], original [1]) to Python. The WebUSB based tool does not work on Linux for some reason.
There is also a custom fastboot binary in circulation [2] which implements a custom command for unlocking the bootloader.
unisoc-unlock implements the same functionality, but without resorting to a custom fastboot binary. Since it is a pure Python solution it should be able to run on any platform running Python.
unisoc-unlock is implemented with python-adb [3]. Since python-adb is abandoned and
requires some tweaking to work with the Unisoc, it is not referenced as dependency, but bundled instead.
Install with pip:
pip3 install unisoc-unlockusage: unisoc_unlock [-h] [--version] [command]
Lock/Unlock tool for Spreadtrum/Unisoc bootloader
positional arguments:
command Command (lock|unlock), default=unlock
options:
-h, --help show this help message and exit
--version show program's version number and exit
- Reboot device into fastboot mode
adb reboot bootloader
-
Wait for 'fastboot mode' to show up on the device screen
-
Run the python script
python3 -m unisoc_unlock unlock # To unlock the bootloader
python3 -m unisoc_unlock lock # To re-lock the bootloader
-
Confirm unlocking on the device
Note: on the RG405M, the text on the device screen will ask for 'volume down' button to confirm unlock, but the home/back button has to be pressed instead!
