Samsung Galaxy S24+ (SM-S926B) Firmware Overview
What is the latest SM-S926B firmware?
S926BXXSIEZJ1, released October 15, 2026 with Android 17. It is a security update on bootloader binary 18. The archive holds 54 official builds across 41 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 31 of 41 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-S926B builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: S926BXXUHEZIF (Sep 2026), 35 builds in total
- Android 16: S926BXXSHDZI1 (Sep 2026), 19 builds in total
Can I downgrade the SM-S926B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 17 to 18:
- Binary 18 — since Oct 2026
- Binary 17 — since Sep 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.
