Firmware or service package for the Xiaomi Redmi Note 5, compressed in a 1.9 MB RAR archive; the name also carries a source website tag. The small size suggests a partial file set rather than a full ROM, and the name does not state the contents, region or version, so inspect it before use. Phone firmware of this kind is typically applied with a flashing tool or used to restore specific partitions. Check that the device variant and hardware match, and back up the phone's existing data and calibration partitions before writing anything.
