Xiaomi Redmi S2 (ysl) Redmi y2

BIOS .rar 16.8 MB Shared

Firmware package for the Xiaomi Redmi S2, also sold as Redmi Y2, with device code name ysl. The archive is a 16.8 MB RAR file, so it probably holds partial images or service files rather than a full ROM. Inspect the contents before use, and match the code name and region of the handset. Flashing the wrong partitions can leave the phone unbootable, so back up whatever is possible first and use a suitable tool such as a Qualcomm flasher for this platform.
