Samsung Galaxy Z Fold7 (SM-F966B) Firmware Overview
What is the latest SM-F966B firmware?
F966BXXUDCZJB, released October 20, 2026 with Android 17. It is a feature update on bootloader binary 13. The archive holds 224 official builds across 76 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy Z Fold7 still getting updates?
Yes. The newest build is from October 2026, and 44 of 76 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-F966B builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: F966BXXUCCZIH (Sep 2026), 102 builds in total
- Android 16: F966BXXS8AZB6 (Feb 2026), 122 builds in total
Can I downgrade the SM-F966B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 8 to 13:
- Binary 13 — since Oct 2026
- Binary 12 — since Aug 2026
- Binary 11 — since Jul 2026
- Binary 10 — since Jun 2026
- Binary 9 — since Apr 2026
- Binary 8 — since Feb 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.
