Samsung Galaxy A54 5G (SM-A546W) Firmware Overview
What is the latest SM-A546W firmware?
A546WVLSLFZI2, released September 14, 2026 with Android 16. It is a security update on bootloader binary 21. The archive holds 20 official builds across 17 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy A54 5G still getting updates?
Yes. The newest build is from September 2026, and 17 of 17 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-A546W firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 20 to 21:
- Binary 21 — since Sep 2026
- Binary 20 — since Aug 2026
A phone already on binary 21 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 21 build. How to read a build number.
