Samsung Galaxy A14 5G (SM-A146B) Firmware Overview
What is the latest SM-A146B firmware?
A146BXXSFDZI2, released September 21, 2026 with Android 15. It is a security update on bootloader binary 15. The archive holds 20 official builds across 2 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy A14 5G still getting updates?
Yes. The newest build is from September 2026, and 2 of 2 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-A146B builds in the archive run Android 14 to 15. The earliest build we have for each version:
- Android 15: A146BXXU8DYF4 (Jun 2025), 16 builds in total
- Android 14: A146BXXU8CXK1 (Nov 2024), 4 builds in total
Can I downgrade the SM-A146B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 8 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
- Binary 10 — since Oct 2025
- Binary 9 — since Aug 2025
- Binary 8 — since Nov 2024
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.
