Samsung Galaxy S26 (SM-S942B) Firmware Overview
What is the latest SM-S942B firmware?
S942BXXS4BZIG, released September 24, 2026 with Android 17. It is a security update on bootloader binary 4. The archive holds 105 official builds across 65 regions (CSC).
Is the Samsung Galaxy S26 still getting updates?
Yes. The newest build is from September 2026, and 23 of 65 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-S942B builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: S942BXXS4BZIG (Sep 2026), 23 builds in total
- Android 16: S942BXXS2AZE2 (May 2026), 82 builds in total
Can I downgrade the SM-S942B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 2 to 4:
- Binary 4 — since Jul 2026
- Binary 3 — since Jun 2026
- Binary 2 — since Apr 2026
A phone already on binary 4 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 4 build. How to read a build number.
