Samsung Galaxy J3 (SM-J330F) Firmware Overview
What is the latest SM-J330F firmware?
J330FXXU4CZC1, released April 16, 2026 with Android 9. It is a feature update on bootloader binary 4. The archive holds 20 official builds across 20 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy J3 still getting updates?
The last build arrived in April 2026. Updates have slowed down — models late in their support period move to quarterly or half-yearly security patches before they stop.
Can I downgrade the SM-J330F 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 4:
- Binary 4 — since Apr 2021
- Binary 3 — since Jan 2018
- Binary 2 — since Dec 2017
- Binary 1 — since Jun 2017
A phone already on binary 4 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 4 build. How to read a build number.

How to Flash SM-J330F Firmware
Put the Samsung Galaxy J3 into Download Mode, load the BL, AP, CP and CSC files into Odin on a Windows PC and press Start. Pick a build with Bit 4 or higher if your phone is already on the latest firmware. Use HOME_CSC to keep your data, CSC for a full wipe.
