Samsung SM-J330N Firmware Overview
What is the latest SM-J330N firmware?
J330NKOU6CUD1, released May 17, 2021 with Android 9. It is a feature update on bootloader binary 6. The archive holds 15 official builds across 1 region (CSC).
Is the Samsung SM-J330N still getting updates?
Most likely not: there has been no new firmware since May 2021, so Android 9 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-J330N builds in the archive run Android 8 to 9. The earliest build we have for each version:
- Android 9: J330NKOU3CSH7 (Aug 2019), 7 builds in total
- Android 8: J330NKOU1BRK1 (Nov 2018), 7 builds in total
Can I downgrade the SM-J330N 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 6:
- Binary 6 — since Nov 2020
- Binary 5 — since Jun 2020
- Binary 4 — since Nov 2019
- Binary 3 — since May 2019
- Binary 2 — since Mar 2019
- Binary 1 — since Nov 2018
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.
