Owning a Xiaomi Redmi Note 8T offers plenty of room for experimentation, but standard Android operating system limitations often prevent you from unlocking the full potential of your device. Obtaining superuser rights, or root access, allows you to uninstall system software, change processor frequency, and install specialized modules. However, this process requires care, since interfering with the system partition can lead to a loss of warranty or software errors.
Before you start modifying, you need to realize that Mi Unlock and Magisk are tools that change the structure of the boot image. Unlike the usual interface setting, here you work with low-level components of the Snapdragon 665 platform. Any error when you run a recover firmware or patch the kernel can turn the phone into a brick, so it's important to follow the algorithm of actions strictly.
