Samsung Galaxy A5 (SM-A5100) Firmware Overview
What is the latest SM-A5100 firmware?
A5100ZHS2CTH1, released November 18, 2020 with Android 6.0.1. It is a security update on bootloader binary 2. The archive holds 20 official builds across 2 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy A5 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-A5100 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: A5100ZCU1CRL1 (Dec 2018), 10 builds in total
- Android 6.0.1: A5100ZCU1BQG1 (Jul 2017), 7 builds in total
Can I downgrade the SM-A5100 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 Feb 2019
- 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.
