Samsung SM-A315N Firmware Overview
What is the latest SM-A315N firmware?
A315NKSU4DXJ1, released October 4, 2024 with Android 12. It is a feature update on bootloader binary 4. The archive holds 20 official builds across 4 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung SM-A315N still getting updates?
Most likely not: there has been no new firmware since October 2024, so Android 12 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-A315N 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 4:
- Binary 4 — since Dec 2023
- Binary 3 — since Jun 2023
- Binary 2 — since Jan 2023
- Binary 1 — since Aug 2022
A phone already on binary 4 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 4 build. How to read a build number.
