Samsung Galaxy S25 FE (SM-S731B) Firmware Overview
What is the latest SM-S731B firmware?
S731BXXS9CZJ2, released October 9, 2026 with Android 17. It is a security update on bootloader binary 9. The archive holds 206 official builds across 76 regions (CSC).
Is the Samsung Galaxy S25 FE still getting updates?
Yes. The newest build is from October 2026, and 20 of 76 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-S731B builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: S731BXXU9CZIF (Sep 2026), 60 builds in total
- Android 16: S731BXXS5AZB6 (Mar 2026), 146 builds in total
Can I downgrade the SM-S731B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 5 to 9:
- Binary 9 — since Aug 2026
- Binary 8 — since Jul 2026
- Binary 7 — since Jun 2026
- Binary 6 — since May 2026
- Binary 5 — since Feb 2026
A phone already on binary 9 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 9 build. How to read a build number.
