Samsung SM-G981N Firmware Overview
What is the latest SM-G981N firmware?
G981NKSS8IYC2, released March 27, 2025 with Android 13. It is a security update on bootloader binary 8. The archive holds 20 official builds across 4 regions (CSC).
Is the Samsung SM-G981N still getting updates?
Most likely not: there has been no new firmware since March 2025, so Android 13 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Can I downgrade the SM-G981N firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 4 to 8:
- Binary 8 — since Mar 2025
- Binary 7 — since Jan 2025
- Binary 6 — since Oct 2024
- Binary 5 — since Aug 2024
- Binary 4 — since May 2024
A phone already on binary 8 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 8 build. How to read a build number.
