Xiaomi Redmi note 9 Pro

BIOS .rar 1.90 MB Shared

Service material for the Xiaomi Redmi Note 9 Pro packed in a 1.90 MB RAR archive. The name says nothing about the contents beyond the model, and the index classes it as BIOS / firmware, so open the archive to see whether it holds firmware, a schematic or other repair data. For smartphone mainboard work such files help with power-rail tracing, charging faults and component location. Make sure the material matches your exact hardware variant, as Xiaomi models are often sold in several regional versions.

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 @SMART_PHONE_SCHEMATICS. Enginerys does not host this file.
