Dear All,


Unlocking Method


Our Xiaomi Mi A1 is locked and needs to be unlocked before flashing anything.


STEPS:

1. Power off your handset.
2. Press and hold volume down button and connect the handset to the pc/laptop.
3. Handset will now enter into fastboot mode.
4. Open command prompt on your pc/laptop and run the following command:


fastboot oem unlock


5. Your phone will be unlocked.


*** Make a backup of all your data as it might get erased during the process***

*** Warning***
After you unlock the device, it will become less secure. Your personal data might be leaked or lost.
Please think twice before flashing your phone and do it at your own risk.

You didn't bother to include on How to tick USB debugging before entering Fastboot mode and adb unlocking. Some beginners won't able succeed with it.

That's already common knowledge tho since you are using ADB to push the unlock bootloader command. They shouldn't unlock their bootloader if they do not know things as simple as that, tbh.

I have MI A2 Lite and it's with Android one. Can I unlock it with some tool and root it without affecting the warranty. And does Xiaomi key for unlock is needed only for MIUI interface.
Thanks in advance.
