Archive for the Xiaomi Redmi K30 4G, catalogued as firmware. The size is under 1 MB, much smaller than a full ROM, so the contents may be a partial file, a configuration image or documentation, and should be inspected after extracting. The 4G variant uses different hardware from the 5G and Pro models, so files are not interchangeable. Before flashing anything to a Xiaomi phone, back up the data and partitions where possible, and use fastboot or EDL tools that match the device.
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.
