Samsung Galaxy J7 Duo (SM-J720M) Firmware Overview
What is the latest SM-J720M firmware?
J720MUBUBCUL1, released February 8, 2022 with Android 10. It is a feature update on bootloader binary 11. The archive holds 20 official builds across 9 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy J7 Duo still getting updates?
Most likely not: there has been no new firmware since February 2022, 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-J720M 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 11:
- Binary 11 — since Mar 2021
- Binary 3 — since Sep 2018
- Binary 2 — since Jun 2018
- Binary 1 — since Apr 2018
A phone already on binary 11 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 11 build. How to read a build number.
