Xiaomi RedMi Note 4 (nikel)

BIOS .rar 1.22 MB Shared

Firmware package for the Xiaomi Redmi Note 4 with the code name nikel, delivered as a 1.22 MB RAR file. That compact size suggests a loader, scatter or partition files and similar service material. It is mainly useful for reviving dead phones or repairing specific partitions with a suitable flashing tool. Nikel is a separate variant from the Note 4X (mido), so make sure the device identifies as nikel. Extract the archive with WinRAR or 7-Zip, inspect the contents and back up the phone before any write.
