Samsung Galaxy Z Fold7 (SM-F9660) Firmware Overview
What is the latest SM-F9660 firmware?
F9660ZSSDCZJ1, released October 12, 2026 with Android 17. It is a security update on bootloader binary 13. The archive holds 22 official builds across 3 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 2 of 3 regions already have a build from that month; the rest usually follow within a few weeks.
Which Android versions did it get?
The SM-F9660 builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: F9660ZSUCCZIH (Sep 2026), 4 builds in total
- Android 16: F9660ZSS9AZC8 (Apr 2026), 18 builds in total
Can I downgrade the SM-F9660 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 11 — since Jul 2026
- Binary 10 — since May 2026
- Binary 9 — since Mar 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.
