Samsung SM-A307GN Firmware Overview
What is the latest SM-A307GN firmware?
A307GNDXS6CWH1, released September 13, 2023 with Android 11. It is a security update on bootloader binary 6. The archive holds 20 official builds across 15 regions (CSC).
Is the Samsung SM-A307GN still getting updates?
Most likely not: there has been no new firmware since September 2023, so Android 11 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-A307GN firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 5 to 6:
- Binary 6 — since Aug 2023
- Binary 5 — since Mar 2023
A phone already on binary 6 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 6 build. How to read a build number.
