Samsung Galaxy A6+ (SM-A605GN) Firmware Overview
What is the latest SM-A605GN firmware?
A605GNUBU9CWC1, released March 15, 2023 for region TMM with Android 10. It is a feature update on bootloader binary 9. The archive holds 2 official builds for this region.
Is the Samsung Galaxy A6+ still getting updates?
Most likely not: there has been no new firmware since March 2023, so Android 10 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-A605GN firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 8 to 9:
- Binary 9 — since Mar 2023
- Binary 8 — since Nov 2021
A phone already on binary 9 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 9 build. How to read a build number.
