Samsung SM-N981N Firmware Overview
What is the latest SM-N981N firmware?
N981NKSSAHYH1, released August 28, 2025 with Android 13. It is a security update on bootloader binary 10. The archive holds 20 official builds across 4 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung SM-N981N still getting updates?
Most likely not: there has been no new firmware since August 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-N981N firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 7 to 10:
- Binary 10 — since Aug 2025
- Binary 9 — since Jul 2025
- Binary 8 — since Apr 2025
- Binary 7 — since Jan 2025
A phone already on binary 10 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 10 build. How to read a build number.
