Samsung Galaxy J8 (SM-J810M) Firmware Overview
What is the latest SM-J810M firmware?
J810MUBU3CWB1, released March 12, 2023 with Android 10. It is a feature update on bootloader binary 3. 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 Galaxy J8 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-J810M 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 3:
- Binary 3 — since Jun 2021
- Binary 2 — since Oct 2018
- Binary 1 — since Jun 2018
A phone already on binary 3 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 3 build. How to read a build number.
