Samsung Galaxy A54 5G (SM-A546E) Firmware Overview
What is the latest SM-A546E firmware?
A546EXXSNFZI1, released September 11, 2026 for region COO with Android 16. It is a security update on bootloader binary 23. The archive holds 3 official builds for this region.
Is the Samsung Galaxy A54 5G still getting updates?
Yes. The newest build is from September 2026.
Can I downgrade the SM-A546E firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 18 to 23:
- Binary 23 — since Sep 2026
- Binary 19 — since May 2026
- Binary 18 — since Feb 2026
A phone already on binary 23 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 23 build. How to read a build number.
