Samsung Android 14 to 15 Downgrade Guide — Is It Possible?

Published 2025-12-09T21:00:00.000000Z.

Samsung Downgrade Limitations

Samsung binary rollback protection (BIT/SW REV) prevents downgrading to firmware with a lower binary version. However, downgrading within the same binary is sometimes possible if the security patch allows it.

When Downgrade Works

• Same binary version — e.g., BIT 5 Android 15 to BIT 5 Android 14
• Using HOME_CSC to preserve user data during flash
• When security patch level is the same or older than target firmware
