Samsung SM-A307GT Firmware Overview
What is the latest SM-A307GT firmware?
A307GTVJS5CWE3, released June 1, 2023 with Android 11. It is a security update on bootloader binary 5. The archive holds 20 official builds across 5 regions (CSC).
Is the Samsung SM-A307GT still getting updates?
Most likely not: there has been no new firmware since June 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-A307GT firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 4 to 5:
- Binary 5 — since Nov 2022
- Binary 4 — since Jul 2022
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.
