Samsung Galaxy Quantum7 (SM-A576S) Firmware Overview
What is the latest SM-A576S firmware?
A576SKSS3BZJ2, released October 14, 2026 with Android 17. It is a security update on bootloader binary 3. The archive holds 4 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 Quantum7 still getting updates?
Yes. The newest build is from October 2026.
Which Android versions did it get?
The SM-A576S builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: A576SKSU2BZIE (Sep 2026), 2 builds in total
- Android 16: A576SKSU1AZG7 (Jul 2026), 2 builds in total
Can I downgrade the SM-A576S 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 3:
- Binary 3 — since Oct 2026
- Binary 2 — since Aug 2026
- Binary 1 — since Jul 2026
A phone already on binary 3 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 3 build. How to read a build number.
