Samsung Galaxy A3 (SM-A300M) Firmware Overview
What is the latest SM-A300M firmware?
A300MUBS1BRK2, released May 12, 2021 with Android 5.0.2. It is a security update on bootloader binary 1. 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 still getting updates?
Most likely not: there has been no new firmware since May 2021, so Android 5.0.2 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-A300M builds in the archive run Android 4.4.4 to 5.0.2. The earliest build we have for each version:
- Android 5.0.2: A300MUBS1BRK3 (Jan 2021), 18 builds in total
- Android 4.4.4: A300MUBS1BRK3 (Mar 2021), 2 builds in total
Can I downgrade the SM-A300M firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. All decodable builds in the archive share binary 1:
- Binary 1 — since Nov 2014
