Samsung Galaxy A3 (2016) SM-A310M Firmware Overview
What is the latest SM-A310M firmware?
A310MUBS3CTI1, released October 20, 2020 with Android 7. It is a security update on bootloader binary 3. The archive holds 20 official builds across 20 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy A3 (2016) still getting updates?
Most likely not: there has been no new firmware since October 2020, so Android 7 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-A310M builds in the archive run Android 5.1.1 to 7. The earliest build we have for each version:
- Android 7: A310MUBS3CTI1 (Oct 2020), 9 builds in total
- Android 6.0.1: A310MUBS3CTH7 (Oct 2020), 6 builds in total
- Android 5.1.1: A310MUBS3CTI1 (Oct 2020), 5 builds in total
Can I downgrade the SM-A310M 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 3:
- Binary 3 — since Jan 2018
- Binary 2 — since Mar 2016
- Binary 1 — since Dec 2015
A phone already on binary 3 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 3 build. How to read a build number.
