Samsung Galaxy Z Flip7 (SM-F766B) Firmware Overview
What is the latest SM-F766B firmware?
F766BXXSDCZJ1, released October 8, 2026 for region EON with Android 17. It is a security update on bootloader binary 13. The archive holds 2 official builds for this region.
Is the Samsung Galaxy Z Flip7 still getting updates?
Yes. The newest build is from October 2026.
Can I downgrade the SM-F766B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 12 to 13:
- Binary 13 — since Oct 2026
- Binary 12 — since Sep 2026
A phone already on binary 13 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 13 build. How to read a build number.
