Step 2. Here you will see the blue button named “Unlock Now”. Click it.

Step 6. Here enter your Name, Number and the reason to unlock the bootloader. And tap on the button ‘Apply Immediately’.

I prefer you to give the reason for unlocking in the Chinese language for a quick approval. You can use Google Translate to do so.

Also, do not write a long reason, keep it short and simple. For example template you can quote the reason as ‘Phone is bricked, I request you to accept my approval’. In Chinese, it writes as “电话是bricked，我要求你接受我的批准”.u

Step 7. In the next page, you’ll need to enter the verification code sent to you via SMS. The servers are slow so it may take some time for you to get the SMS, do not tap on re-send SMS/Code multiple times.

If you get an error message, wait and apply after 24 hours.

Step 8. Once done, you will see a page stating “Application has been successfully submitted”. 

It will take around 2-10 days for approval and you will receive the confirmation via SMS. The application is approved manually.

If it is not approved then go to Help Forum and take help of the support.

Step 9. Once you get the confirmation you can proceed forward with the unlocking process.

Note: 

• Make sure your Mi account is not associated with 2 devices. If it is so then an error may occur.
• After unlocking the boot loader your device becomes less secure and more vulnerable to malware.
• Some features which require high-security level (e.g., Find device, added-value services, etc.) will no longer be available.
• You might no longer be able to receive regular updates and enjoy the newest features of MIUI.
