MiForge/MiUnlockTool ? reverse-engineered prompt

Build me a simple cross platform Python tool that helps Xiaomi phone users retrieve the encryptData token they need for bootloader unlocking. I want it to work from the command line, be easy to install with pip, and run with a single command like miunlock.

It should guide the user through logging in, support saving the login session, and handle verification by SMS or email. If possible, make the server region choice automatic, but also let the user set it manually when needed. Keep the flow straightforward and friendly, since this is meant for normal users trying to unlock their device, not developers.

Please include clear help text, good error messages, and basic documentation for installation and usage. If you need to check current Xiaomi or Python library details online while building it, go ahead and look them up.
