Samsung Galaxy S24+ (SM-S926N) Firmware Overview
What is the latest SM-S926N firmware?
S926NKSSIEZJ1, released October 13, 2026 with Android 17. It is a security update on bootloader binary 18. The archive holds 24 official builds across 4 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy S24+ still getting updates?
Yes. The newest build is from October 2026, and 4 of 4 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-S926N builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: S926NKSUHEZIF (Sep 2026), 8 builds in total
- Android 16: S926NKSSFDZE1 (May 2026), 16 builds in total
Can I downgrade the SM-S926N firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 15 to 18:
- Binary 18 — since Oct 2026
- Binary 17 — since Aug 2026
- Binary 16 — since Jul 2026
- Binary 15 — since May 2026
A phone already on binary 18 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 18 build. How to read a build number.
