Samsung Galaxy J8 (SM-J810G) Firmware Overview
What is the latest SM-J810G firmware?
J810GDDU6CWH2, released August 30, 2023 with Android 10. It is a feature update on bootloader binary 6. The archive holds 20 official builds across 5 regions (CSC).
Is the Samsung Galaxy J8 still getting updates?
Most likely not: there has been no new firmware since August 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-J810G 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 6:
- Binary 6 — since Sep 2021
- Binary 5 — since Apr 2021
- Binary 4 — since Mar 2021
- Binary 2 — since Oct 2018
- Binary 1 — since Jun 2018
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.
