Samsung Galaxy Quantum4 (SM-A546S) Firmware Overview
What is the latest SM-A546S firmware?
A546SKSUKGZJ5, released October 12, 2026 with Android 17. It is a feature update on bootloader binary 20. The archive holds 28 official builds across 1 region (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy Quantum4 still getting updates?
Yes. The newest build is from October 2026.
Which Android versions did it get?
The SM-A546S builds in the archive run Android 14 to 17. The earliest build we have for each version:

Can I downgrade the SM-A546S firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 6 to 20:
- Binary 20 — since Sep 2026
- Binary 19 — since Aug 2026

A phone already on binary 20 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 20 build. How to read a build number.

How to Flash SM-A546S Firmware
