Samsung SM-T865N Firmware Overview
What is the latest SM-T865N firmware?
T865NKOU6DXJ1, released October 3, 2024 with Android 12. It is a feature update on bootloader binary 6. The archive holds 20 official builds across 1 region (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung SM-T865N still getting updates?
Most likely not: there has been no new firmware since October 2024, so Android 12 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Which Android versions did it get?
The SM-T865N builds in the archive run Android 10 to 12. The earliest build we have for each version:
- Android 12: T865NKOU5DVD3 (Apr 2022), 9 builds in total
- Android 11: T865NKOU4CUC2 (Mar 2021), 7 builds in total
- Android 10: T865NKOU4BTI1 (Sep 2020), 4 builds in total
Can I downgrade the SM-T865N 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 6:
- Binary 6 — since Aug 2023
- Binary 5 — since Sep 2021
- Binary 4 — since Sep 2020
A phone already on binary 6 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 6 build. How to read a build number.
