Samsung Galaxy A54 5G (SM-A546V) Firmware Overview
What is the latest SM-A546V firmware?
A546VSQSNFZJ5, released October 29, 2026 with Android 16. It is a security update on bootloader binary 23. The archive holds 20 official builds across 3 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 October 2026, and 3 of 3 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-A546V firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 19 to 23:
- Binary 23 — since Sep 2026
- Binary 22 — since Aug 2026
- Binary 21 — since Jul 2026
- Binary 20 — since Jun 2026
- Binary 19 — since May 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.
