Samsung SM-A3051 Firmware Overview
What is the latest SM-A3051 firmware?
A3051XXS4CWA3, released January 31, 2023 with Android 11. It is a security update on bootloader binary 4. The archive holds 16 official builds across 1 region (CSC).
Is the Samsung SM-A3051 still getting updates?
Most likely not: there has been no new firmware since January 2023, so Android 11 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-A3051 builds in the archive run Android 9 to 11. The earliest build we have for each version:
- Android 11: A3051XXU4CUE4 (Jun 2021), 5 builds in total
- Android 10: A3051XXU3BTA4 (Jan 2020), 8 builds in total
- Android 9: A3051XXU2ASH4 (Sep 2019), 3 builds in total
Can I downgrade the SM-A3051 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 2021
- Binary 3 — since Nov 2019
- Binary 2 — since Aug 2019
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.
