Xiaomi Mi 9T Redmi K20 (davinci)

BIOS .rar 1.36 MB Shared

Firmware material for the Xiaomi Mi 9T, marketed in China as the Redmi K20, code name davinci, supplied as a 1.36 MB RAR. The size rules out a full system image, so expect partial files, loaders or service data; no version or region is stated. Extract it and identify each file before flashing anything. Always save a backup of the original partitions with your flashing tool, and make sure the phone is davinci rather than the Pro model raphael, since the two use different hardware and their images are not interchangeable.

The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @canalesquematicos. Enginerys does not host this file.
