In general, there has been an unofficial TWRP port on Xiaomi Mi A3 for some time, but if you were waiting for the official assembly from the developers, your wait is finally over. From today, TWRP is officially available for the Xiaomi Mi A3.
But remember: Before you start setting up your phone and connecting it to a PC for the flashing process, be sure to read the instructions. This is because Xiaomi Mi A3 uses the A / B partition system, and the flashing procedure is somewhat different from the standard method.

As for the Redmi Note 8 Pro, this device also received its TWRP, but in the case of this device, be extremely careful. The fact is that unlike other Redmi devices powered by Snapdragon, the Redmi Note 8 Pro is built on the MediaTek Helio G90T chip, which makes it not the best smartphone when it comes to flashing or modding. For reasons unknown at the moment, you may end up with a “brick” and lose the performance of your device (Without spending money or visiting a service center, it is impossible to restore this device at the moment. Be careful and if you are not fully confident in your abilities, it is better do not to start modifying Redmi Note 8 Pro yet).
If you understand the risk and still want to try TWRP, then follow this link, where you can download the current version of the image for installation via fastboot and read the detailed instructions.
