How to unlock bootloader on Xiaomi Redmi 9 Prime

On the rear, the Redmi 9 Prime sports a quad-camera setup (13+8+5+2 MP) which is mediocre, to say the least. It takes good photos when given an ample amount of light but just doesn’t expect it to beat the likes of the Poco X2 or Redmi Note 9 Pro. The front camera is an 8 MP sensor which is great for taking selfies. The Redmi 9 Prime comes with Android 10 out of the box with a layer of MIUI 11 on top. It supports dual-SIM connectivity and comes with a base storage of 64GB which is expandable up to 512GB via the external micro SD card slot.

What is Bootloader Unlock?

A bootloader is a program that is the first thing that boots up in your device whenever you turn ON your device. It commands the device to run the appropriate programs in order to run smoothly and provide better performance. Moreover, the bootloader is stored away from the reach of the user and is stored at a stable memory so that the user could not hamper the files. However, there are methods and ways via which you can safely unlock the bootloader of the device and go ahead with flashing a custom recovery to root your device. But, you should make sure to follow a reliable guide and follow the steps correctly in order to avoid any permanent damage to your phone.
