Samsung Galaxy J4 Prime (SM-J415FN) Firmware Overview
What is the latest SM-J415FN firmware?
J415FNXXU6BZB2, released April 20, 2026 with Android 9. It is a feature update on bootloader binary 6. The archive holds 20 official builds across 19 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy J4 Prime 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-J415FN 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 Oct 2022
- Binary 1 — since Sep 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.
