Dump file for the Xiaomi Redmi 9, code name lancelot, in a 35.5 MB RAR archive. It contains storage data used to recover a dead, hard-bricked or bootlooping phone, typically written to the eMMC through ISP points or a programmer box. Confirm that the device code name matches, since Redmi models with similar names use different hardware. Read and keep a backup of the phone's own memory before writing, because IMEI, calibration and security partitions are unique to each handset.
