How To Unlock Bootloader In Xiaomi Mi 8 Se With... May 2026

Important Note:

As of mid-2026, Xiaomi has officially shut down its global bootloader unlock service and the associated permission system for newer models. However, for legacy devices like the Mi 8 SE (released 2018), the old method may still work if you have an older MIUI version installed. If you are on a newer "HyperOS" community build, unlocking may be impossible without authorized Mi engineer credentials. This guide assumes you are running MIUI 12 or older .

• "Current account is not bound to this device": Go back to Developer Options > Mi Unlock Status and tap "Add account and device" again. Ensure your SIM card is inserted and internet is working.
• "Couldn't verify device": This is usually a driver issue or a connection issue. Try a different USB port (use USB 2.0 if 3.0 fails) or a different PC.
• "10000": This usually means the Mi Account does not have permission. You may need to use the "Mi Community" app to apply for unlocking permissions manually if the binding method fails.

Two possible screens appear:

1. Go to en.miui.com/unlock – Xiaomi’s official unlock portal.
2. Download the Mi Unlock Tool (latest version).
3. Extract the ZIP file to a folder on your PC (e.g., C:\MiUnlock).

Enable OEM Unlocking:

Go to Settings > Additional settings > Developer options and toggle on OEM unlocking and USB debugging . How to unlock Bootloader in XIAOMI Mi 8 SE with...
