Samsung Galaxy A3 (SM-A300YZ) Firmware Overview
What is the latest SM-A300YZ firmware?
A300YZUJS1BRH2, released November 27, 2020 with Android 5.0.2. It is a security update on bootloader binary 1. The archive holds 20 official builds across 4 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 November 2020, 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.
Can I downgrade the SM-A300YZ 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
