Samsung Galaxy S25 (SM-S931B) Firmware Overview
What is the latest SM-S931B firmware?
S931BXXSDDZJ1, released October 9, 2026 with Android 17. It is a security update on bootloader binary 13. The archive holds 241 official builds across 74 regions (CSC).
Is the Samsung Galaxy S25 still getting updates?
Yes. The newest build is from October 2026, and 20 of 74 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-S931B builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: S931BXXUCDZIF (Sep 2026), 60 builds in total
- Android 16: S931BXXS7BYLR (Jan 2026), 181 builds in total
Can I downgrade the SM-S931B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 7 to 13:
- Binary 13 — since Oct 2026
- Binary 12 — since Aug 2026
- Binary 11 — since Jul 2026
- Binary 10 — since Jun 2026
- Binary 9 — since Apr 2026
- Binary 8 — since Feb 2026
- Binary 7 — since Dec 2025
A phone already on binary 13 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 13 build. How to read a build number.
