[Guide] How to Unlock the Bootloader of your Mi Phones

Hello Mi Fans!
MIUI has been one of the user-centric ROM from the early days of development. In a scenario where the user has lost the device, to protect users' data and prevent unauthorized access to the device by flashing another ROM, Mi devices now come with the locked bootloader. Adding to that, another reason for this protection mechanism is to serve you the best user experience and to preserve the best flawless MIUI experience from third-party sellers reflashing Mi devices with altered ROMs.

We do understand your need for unlocking bootloader and due to a technical glitch, users weren't able to unlock the bootloader on Redmi Note 5 smartphones. The issue has since been fixed and users should be able to unlock the bootloader on their Redmi Note 5 normally.

Here's the procedure on how to unlock the bootloader:

1. Apply for Bootloader Unlocking Permission
  • How to Apply for Bootloader Unlocking Permission
  • Visit here
  • Click on ‘Unlock Now’
  • Log in with your MI Account for which Bootloader unlock permission is required
  • Now click ‘Unlock Now’ again
  • Enter your name, choose your region/country code, enter your mobile number to which Mi Account is associated and enter the valid/genuine reason you are applying for Bootloader unlocking permission
  • Enter the security code shown in the image, read & accept the terms, click ‘Apply now’
  • Enter the OTP received to the mobile number given and click ‘Next’ to submit the application.
  • Now wait for the approval SMS which might take few hours to few days

  • After receiving the approval SMS,
  • Go to Settings - About phone -  MIUI Version - keep tapping it to enable developer option
  • Go to Settings - Additional settings - Developer option and bind your approved Mi account under Mi Unlock Status
  • If it shows 86006 error, log out and login Mi account again & try again

2. Unlock the bootloader using Mi Unlock tool
  • Bootloader Unlocking Procedure
  • Download & install Mi Unlock tool from here
  • Open Mi Unlock tool, enter your credentials & login to your Mi-Account
  • Turn off your device
  • Hold ‘Volume down’ key and ‘Power button’ simultaneously to enter into Fastboot mode
  • Connect your phone to PC using USB cable & click 'Unlock'

Let the process complete and you will have your bootloader unlocked

  • Make sure both the Mi Accounts are same in the device and in unlock tool
  • If you are the new user and never applied for unlocking before, in step 1 it will take you to the page for username creation and then you can fill in the details and proceed.
  • Do note that unlocking bootloader will erase user data
  • You can only unlock your own device. One Mi account can only unlock one device in 30 days
  • Make sure your PC has necessary drivers and you're on official MIUI ROM before you start to unlock, download and install latest Mi PC Suite & Mi Flash
  • After the device is unlocked, it becomes less secure and more vulnerable to malware attacks, which may lead to the disclosure and loss of your private data. Some features which require high-security level (e.g., Find device, added-value services, etc.) will no longer be available. You are recommended to lock the bootloader after flashing the ROM via Fastboot mode for better security.

How long does it take to receive the SMS from Xiaomi?
Check what is showing on the webpage here occasionally. Once the download Mi Unlock Tool webpage is shown means you’ve been approved. Currently only supported on Windows OS.

Can I re-apply if my application gets rejected?
If your application is rejected then tap on the 'Re-apply' option shown on the web page or apply again here

How to check whether the bootloader is locked/unlocked?

Mi Unlock tool will show the message ‘Unlocked’
An ‘Unlocked’ word will be shown upon booting
Go to settings - additional settings - developer options - Mi unlock status - will show ‘Unlocked’

How can I relock my bootloader?
While flashing MIUI with Mi Flash tool, select the ‘clean all & lock’ option from below and it will relock the bootloader.

Did you successfully unlock the bootloader?

Users doesn't need to apply for unlock permission now. Just bond your Mi Account with the device and Download Mi Unlock tool. Users may need to wait certain hours before unlocking.

That's a good news. And I really don't like the idea of erasing data of phone while unlocking.
