Samsung Galaxy A51 (SM-A515U1) Firmware Overview
What is the latest SM-A515U1 firmware?
A515U1UESCFXA2, released February 12, 2024 with Android 13. It is a security update on bootloader binary 12. The archive holds 20 official builds across 19 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-A515U1 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 11 to 12:
- Binary 12 — since Jan 2024
- Binary 11 — since Sep 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.
