    Frequently Asked Questions

    J120MUBU1APC1 is Android 5.1.1 firmware for Samsung Galaxy J1, released for 6 countries, 7 CSC codes. Samsung built it on 2016-03-08.

    No. A newer build for SM-J120M is available: J120MUBU2ARE1. Install it instead of J120MUBU1APC1 unless you need this exact version. The previous build was J120MUBU1APB1.

    Download the package for your region (CSC) and unzip it. In Odin, load each file into the slot with the same name: BL, AP, CP (if the package has one) and CSC, or HOME_CSC to keep your data. Odin checks the built-in checksum of every .tar.md5 file before flashing. The Samsung Galaxy J1 must be on bootloader binary 1 or lower.

    This build uses bootloader binary 1. It can be flashed on a Samsung Galaxy J1 running binary 1 or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 11 other builds of this model use the same binary, so you can switch between them in both directions.
