Samsung Galaxy Z Flip7 (SM-F766B) Firmware Overview
What is the latest SM-F766B firmware?
F766BXXUDCZJB, released October 20, 2026 for region XFV with Android 17. It is a feature update on bootloader binary 13. The archive holds 4 official builds for this region. Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy Z Flip7 still getting updates?
Yes. The newest build is from October 2026.
Which Android versions did it get?
The SM-F766B builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: F766BXXUDCZJB (Oct 2026), 1 build in total
- Android 16: F766BXXU9BZDP (May 2026), 3 builds in total
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 9 to 13:
- Binary 13 — since Oct 2026
- Binary 12 — since Aug 2026
- Binary 10 — since Jun 2026
- Binary 9 — since Apr 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.
