Samsung Galaxy J2 Core (SM-J260G) Firmware Overview
What is the latest SM-J260G firmware?
J260GDDS9AVK1, released December 13, 2022 for region BKD with Android 8.1. It is a security update on bootloader binary 9. The archive holds 2 official builds for this region.
Is the Samsung Galaxy J2 Core still getting updates?
Most likely not: there has been no new firmware since December 2022, so Android 8.1 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-J260G firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 8 to 9:
- Binary 9 — since Nov 2022
- Binary 8 — since Apr 2021
A phone already on binary 9 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 9 build. How to read a build number.
