Samsung Galaxy J3 (SM-J320YZ) Firmware Overview
What is the latest SM-J320YZ firmware?
J320YZZTS2ARG1, released August 31, 2018 with Android 5.1.1. It is a security update on bootloader binary 2. The archive holds 11 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 J3 still getting updates?
Most likely not: there has been no new firmware since August 2018, so Android 5.1.1 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-J320YZ 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 2:
- Binary 2 — since Oct 2016
- Binary 1 — since Jan 2016
A phone already on binary 2 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 2 build. How to read a build number.
