Samsung Galaxy A51 (SM-A515U) Firmware Overview
What is the latest SM-A515U firmware?
A515USQSCFXA1, released February 13, 2024 with Android 13. It is a security update on bootloader binary 12. The archive holds 20 official builds across 7 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy A51 still getting updates?
Most likely not: there has been no new firmware since February 2024, so Android 13 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Can I downgrade the SM-A515U firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 10 to 12:
- Binary 12 — since Jan 2024
- Binary 11 — since Sep 2023
- Binary 10 — since Jun 2023
A phone already on binary 12 rejects builds with a lower binary in Odin ("SW REV CHECK FAIL"), so it can go back to an earlier Android version only if that version has a binary 12 build. How to read a build number.
