For anyone that is having trouble unlocking bootloader due to SIM activation not working i finally found a solution after 5 days of scouring the internet. Use the python script below! I don't think this will bypass any wait times on its own, but it did bypass the "phone not activated" error that the official unlock tool was giving me
MiUnlockTool developed to retrieve encryptData(token) for Xiaomi devices for unlocking bootloader, It is compatible with all platforms. - offici5l/MiUnlockTool
