Samsung Galaxy J1 (SM-J120M) Firmware Overview
What is the latest SM-J120M firmware?
J120MUBU2ARE1, released May 4, 2018 with Android 5.1.1. It is a feature update on bootloader binary 2. The archive holds 20 official builds across 15 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy J1 still getting updates?
Most likely not: there has been no new firmware since May 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-J120M 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 Mar 2017
- Binary 1 — since Dec 2015
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.
