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-unlock
usage: 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!
