Xiaomi Redmi Note TD&WCDMA Schematic

BIOS .rar 1.82 MB Shared

Schematic archive for the Xiaomi Redmi Note in its TD and WCDMA variants, about 1.82 MB compressed, although it is indexed under firmware. The name says it is a circuit diagram, so expect PDF pages rather than a flashable image. TD likely refers to the TD-SCDMA version, and the WCDMA version is the one for UMTS networks. The radio front end differs between the two, so confirm which version is on the bench before following RF, PMIC or baseband sections. The diagram is still useful for tracing power rails, charging circuits and display connectors.
