Hi, I have a CN version of the Mi band 7 pro. I got it from my friend (who retired it and described it as "e-waste") and I wonder if I could get an international version of the firmware to run on it. Does this thing have a bootloader lock/secure boot or such? I am an avid fan of Blue Archive. How do I obtain BA-themed watchfaces? Thanks. Oh and Plz do not spam "Epic" "Amine" "rpg"
