How to unlock Xiaomi bootloader on Redmi device

Bootloader Unlock Guide for all Xiaomi MIUI Phones 

Virtually all recent Xiaomi Device like Redmi 3, Redmi 3s, Redmi 3s Prime, Redmi Note 3, Redmi Note 4, Redmi 4, Redmi, Mi Max, Mi Note Pro, Mi 1, Mi 2, Mi 3, Mi 4, Mi Note etc. have their bootloader locked, it’s a good move to protect its device from unauthorized access, especially by hackers.  What this means is that you don’t have the permission to restore, downgrade or upgrade your Xiaomi Phone or Tablet ROM via fastboot.

Do not panic the status is not permanent, you can actually unlock your device bootloader from any part of the world though it may require a little patience as your request to have it unlocked may take a couple of days to get approved.

If it leads to an application form Page, your device is locked and you have to apply for unlocking permission.

Unlocking Tips

• You wouldn’t like to lose your Data I guess, hence Make Sure your Data is backed up.

• Though the process would be brief, I still recommend you have at least 40% charge.

• Make sure your Mi Account is not linked to or associated with more than one Device.

• Your device may become less secure and vulnerable to Malware attack after unlocking it.

• Some feature like regular update, find Device, added-value services etc. might no longer be available when your device is unlocked.

• Unlocking would void your warranty.

• You are following this tutorial at your own risk; we shall not be liable for any claims.
