Samsung Galaxy A7 (SM-A7108) Firmware Overview
What is the latest SM-A7108 firmware?
A7108ZMS4CTI2, released November 16, 2020 with Android 7.1.1. It is a security update on bootloader binary 4. The archive holds 9 official builds across 1 region (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy A7 still getting updates?
Most likely not: there has been no new firmware since November 2020, so Android 7.1.1 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Which Android versions did it get?
The SM-A7108 builds in the archive run Android 6.0.1 to 7.1.1. The earliest build we have for each version:
- Android 7.1.1: A7108ZMU3CSA1 (Jan 2019), 4 builds in total
- Android 6.0.1: A7108ZMU2BQI1 (Sep 2017), 5 builds in total
Can I downgrade the SM-A7108 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 2 to 4:
- Binary 4 — since Feb 2019
- Binary 3 — since Jul 2018
- Binary 2 — since Sep 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.
