Samsung Galaxy S22 Ultra (SM-S908E) Firmware Overview
What is the latest SM-S908E firmware?
S908EXXSEGZH4, released August 21, 2026 with Android 16. It is a security update on bootloader binary 14. The archive holds 89 official builds across 62 regions (CSC).
Is the Samsung Galaxy S22 Ultra still getting updates?
Yes. The newest build is from August 2026, and 40 of 62 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-S908E firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 12 to 14:
- Binary 14 — since May 2026
- Binary 13 — since Feb 2026
- Binary 12 — since Jan 2026
A phone already on binary 14 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 14 build. How to read a build number.

How to Flash SM-S908E Firmware
