Samsung Galaxy A34 5G (SM-A346M) Firmware Overview
What is the latest SM-A346M firmware?
A346MUBSHFZJ4, released October 9, 2026 with Android 16. It is a security update on bootloader binary 17. The archive holds 94 official builds across 44 regions (CSC).
Is the Samsung Galaxy A34 5G still getting updates?
Yes. The newest build is from October 2026, and 2 of 44 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-A346M firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 13 to 17:
- Binary 17 — since Oct 2026
- Binary 16 — since Jul 2026
- Binary 15 — since Mar 2026
- Binary 14 — since Feb 2026
- Binary 13 — since Jan 2026
A phone already on binary 17 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 17 build. How to read a build number.
