Samsung Galaxy On7 Refresh (SM-G611M) Firmware Overview
What is the latest SM-G611M firmware?
G611MUBSACUG3, released October 29, 2021 with Android 9. It is a security update on bootloader binary 10. 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 On7 Refresh still getting updates?
Most likely not: there has been no new firmware since October 2021, so Android 9 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-G611M 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 10:
- Binary 10 — since Apr 2021
- Binary 9 — since Oct 2020
- Binary 3 — since Jul 2018
- Binary 2 — since May 2018
- Binary 1 — since Mar 2018
A phone already on binary 10 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 10 build. How to read a build number.
