The TWRP custom recovery has been around for several years now and it has grown to become the go-to option for the Android community to install any kind of third-party software on their devices. TWRP's open-source nature helped it reach popularity across a wide range of devices. On top of that, features like full backup and restore, ADB sideloading, etc. helped the custom recovery cement its position in the market. Now, TWRP is adding support for a few more devices.
Redmi K20 Pro/Mi 9T Pro
The Xiaomi Mi 9T Pro, which is also known as the Redmi K20 Pro in some regions, was launched earlier this year in May. The device packs in top-of-the-line specs, including Qualcomm's Snapdragon 855 chip, up to 8GB of RAM, and a triple camera setup. While the device has had unofficial TWRP support for a while now, it has now officially received support for the custom recovery.
