Samsung Galaxy A57 5G (SM-A576U) Firmware Overview
What is the latest SM-A576U firmware?
A576USQS4BZJ2, released October 12, 2026 with Android 17. It is a security update on bootloader binary 4. The archive holds 25 official builds across 5 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy A57 5G still getting updates?
Yes. The newest build is from October 2026, and 5 of 5 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-A576U builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: A576USQU4BZIE (Sep 2026), 10 builds in total
- Android 16: A576USQU1AZF9 (Jun 2026), 15 builds in total
Can I downgrade the SM-A576U firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 1 to 4:
- Binary 4 — since Sep 2026
- Binary 3 — since Aug 2026
- Binary 2 — since Jul 2026
- Binary 1 — since Jun 2026
A phone already on binary 4 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 4 build. How to read a build number.
