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). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
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.
