How to Unlock Redmi Note 3 Bootloader

As a matter of fact, Xiaomi never locks the Bootloader of Devices, but for Redmi Note 3 , Xiaomi locked the Bootloader. Xiaomi has clearly explained the key reasons for doing this in Xiaomi Forum.

The key reason mentioned by Xiaomi is ” in order to protect user data safety “. The other reasons are :

  1. To avoid fake Smartphones sold by Un-authorized Re-sellers. Many users have taken the risk of buying from a unofficial reseller. But they sometimes get fake Mi phones, or Mi phones with unofficial ROM loaded with bloatware.
  2. Another major issues, is Stolen Devices. Mi users have often encountered is that, after their Mi phones are lost or stolen , the person who got the device could easily flash a new ROM into it, and makes it almost impossible for our users to get their phones back.

The key changes which users have noticed after Bootloader is locked 

  • Locking bootloader will not affect normal OTA updates
  • ROOT will be disabled if user has enabled it before. Enabling ROOT will need to unlock bootloader
  • Recovery mode is changed. Updating via Recovery will need to use Mi PC Suite
  • Devices with locked bootloader can not update using Miflash. Users need to unlock bootloader if they want to flash Fastboot ROMs.

Before we proceed, Please Note that , if you don’t know that much about Android, flashing, custom ROMs etc. It’s not recommended for you to unlock the bootloader. It might cause serious damage to your device or personal data.

What all you need before you unlock Bootloader 

  • Permission from Xiaomi for un-locking Device ( This process may take any where between 10 ~ 15 days )**
  • A working Internet connection
  • Mi Account logged in from Xiaomi Device
