Samsung SM-A105N Firmware Overview
What is the latest SM-A105N firmware?
A105NKOS5CWA2, released February 16, 2023 with Android 11. It is a security update on bootloader binary 5. The archive holds 15 official builds across 1 region (CSC).
Is the Samsung SM-A105N still getting updates?
Most likely not: there has been no new firmware since February 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-A105N builds in the archive run Android 9 to 11. The earliest build we have for each version:
- Android 11: A105NKOU5CUL4 (Dec 2021), 4 builds in total
- Android 10: A105NKOU2BTD3 (Apr 2020), 6 builds in total
- Android 9: A105NKOU1ASE5 (May 2019), 5 builds in total
Can I downgrade the SM-A105N 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 5:
- Binary 5 — since Apr 2021
- Binary 4 — since Oct 2020
- Binary 3 — since Jul 2020
- Binary 2 — since Nov 2019
- Binary 1 — since May 2019
A phone already on binary 5 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 5 build. How to read a build number.
