Samsung Galaxy J3 (SM-J3308) Firmware Overview
The archive lists 20 official builds for the Samsung Galaxy J3 across 1 region (CSC). The newest one is J3308ZMU4CUE2, released June 18, 2021 with Android 9. Builds cover Android 7.1.1 to 9, the oldest dating from August 2018. It is a feature update on bootloader binary 4: once a phone runs it, firmware with a lower binary can no longer be flashed (how to read a build number).
- Android 9: 13 builds, latest J3308ZMU4CUE2
- Android 8.1: 5 builds, latest J3308ZMS3BSD1
- Android 7.1.1: 2 builds, latest J3308ZMU2ARH1
How to Flash SM-J3308 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 the same or a higher Bit than the one installed — a lower bootloader binary will be rejected.
