Samsung SM-G611FF Firmware Overview
What is the latest SM-G611FF firmware?
G611FFDDS5CUI1, released October 1, 2021 with Android 9. It is a security update on bootloader binary 5. The archive holds 12 official builds across 1 region (CSC).
Is the Samsung SM-G611FF 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.
Which Android versions did it get?
The SM-G611FF builds in the archive run Android 8 to 9. The earliest build we have for each version:
- Android 9: G611FFDDU1CSD8 (Apr 2019), 10 builds in total
- Android 8: G611FFDDU1BRI5 (Sep 2018), 2 builds in total
Can I downgrade the SM-G611FF 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 5:
- Binary 5 — since Sep 2021
- Binary 4 — since Dec 2020
- Binary 3 — since Aug 2020
- Binary 2 — since Mar 2020
- Binary 1 — since Sep 2018
A phone already on binary 5 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 5 build. How to read a build number.
