Xiaomi Mi 9T Pro Redmi K20 Pro (raphael) Schematic

BIOS .7z 992 KB Shared

Archive for the Xiaomi Mi 9T Pro, also sold as the Redmi K20 Pro under the codename raphael, 992 KB in 7z format. The name calls it a schematic while the catalogue lists it as firmware, so open it first to confirm what it actually contains. If it holds circuit diagrams, they serve for tracing power rails, charging paths and connector signals; if it holds firmware, check compatibility with your exact variant. Either way, verify the board revision and back up existing data before acting on it.
