patrislav1/unisoc-unlock — reverse-engineered prompt

Build me a small Python command line tool that can lock or unlock a Unisoc or Spreadtrum Android bootloader using the device identifier token, without needing a special fastboot binary.

I want it to be installable with pip or pipx and usable like python3 -m unisoc_unlock unlock or python3 -m unisoc_unlock lock. It should connect to a device that is already in fastboot mode, send the right unlock or lock command, and then let the user confirm on the device. Include normal help and version output.

Please make the tool clear and safe to use. Add warnings that it has only really been tested on a Unisoc T618 device like the Anbernic RG405M, and explain that other chipsets may fail if the bootloader key is different. Also add friendly troubleshooting messages for USB permission problems and fastboot failures.

Bundle whatever Python USB or fastboot code is needed so users don’t have to install a custom fastboot tool.
