How to unlock the bootloader, root, and install TWRP on the Xiaomi Mi 9

Xiaomi devices are pretty popular around these parts, but their software isn’t everyone’s cup of tea. The good news is Xiaomi allows users to unlock their device bootloaders. You just have to wait through the unlock period before you can do anything. Max from XDA TV has shared a tutorial video about how to do that as well as install TWRP and root with Magisk on the Xiaomi Mi 9. If you’re interested in doing any of this on your Mi 9, watch the video below.
