The Xiaomi Redmi Note 9T 5G official firmware on this page will help you update your phone MIUI version to the latest. To move from Beta to Stable ROM (vice versa) or un-brick your phone, you need Fastboot ROM.
If you previously rooted or modified the system partition of your phone, you should consider flashing the Fastboot ROM. It will overwrite all existing modified system files to replace with factory software. To ensure that all important data on the phone (like contacts, messages, app data, etc.) is safe, back them all up because you could loose data after flashing.
Again, charge the phone to at least 50% so that the flashing process will not be interrupted by low battery. Interrupting the firmware installation means bricking your phone.
Download either the fastboot or recovery firmware from the link(s) below and follow the recommended flashing instructions immediately after the download options. Do not hesitate to report any broken links detected.
