Samsung Galaxy J6 (SM-J600N) Firmware Overview
What is the latest SM-J600N firmware?
J600NKOS5CUL1, released December 22, 2021 with Android 10. It is a security update on bootloader binary 5. The archive holds 17 official builds across 1 region (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy J6 still getting updates?
Most likely not: there has been no new firmware since December 2021, so Android 10 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-J600N builds in the archive run Android 8 to 10. The earliest build we have for each version:
- Android 10: J600NKOU4CTD5 (Apr 2020), 5 builds in total
- Android 9: J600NKOU2BSD5 (Apr 2019), 6 builds in total
- Android 8: J600NKOU1ARG1 (Jul 2018), 6 builds in total
Can I downgrade the SM-J600N firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 1 to 5:
- Binary 5 — since Sep 2020
- Binary 4 — since Jan 2020
- Binary 3 — since Jul 2019
- Binary 2 — since Oct 2018
- Binary 1 — since Jul 2018
A phone already on binary 5 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 5 build. How to read a build number.
