Samsung SM-A376U Firmware Overview
What is the latest SM-A376U firmware?
A376USQU6BZJ2, released October 27, 2026 with Android 17. It is a feature update on bootloader binary 6. The archive holds 20 official builds across 8 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung SM-A376U still getting updates?
Yes. The newest build is from October 2026, and 3 of 8 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-A376U builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: A376USQU5BZI6 (Sep 2026), 11 builds in total
- Android 16: A376USQS4AZG1 (Jul 2026), 9 builds in total
Can I downgrade the SM-A376U firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 4 to 6:
- Binary 6 — since Oct 2026
- Binary 5 — since Aug 2026
- Binary 4 — since Jul 2026
A phone already on binary 6 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 6 build. How to read a build number.
