Samsung Galaxy M14 5G (SM-M146B) Firmware Overview
What is the latest SM-M146B firmware?
M146BXXSFDZI1, released September 21, 2026 with Android 15. It is a security update on bootloader binary 15. The archive holds 98 official builds across 24 regions (CSC).
Is the Samsung Galaxy M14 5G still getting updates?
Yes. The newest build is from September 2026, and 21 of 24 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-M146B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 11 to 15:
- Binary 15 — since Sep 2026
- Binary 14 — since Jul 2026
- Binary 13 — since May 2026
- Binary 12 — since Feb 2026
- Binary 11 — since Dec 2025
A phone already on binary 15 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 15 build. How to read a build number.
