Samsung Galaxy Z Flip8 (SM-F776N) Firmware Overview
What is the latest SM-F776N firmware?
F776NKSU2AZJ8, released October 16, 2026 with Android 17. It is a feature update on bootloader binary 2. The archive holds 24 official builds across 4 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy Z Flip8 still getting updates?
Yes. The newest build is from October 2026, and 4 of 4 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-F776N 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 2:
- Binary 2 — since Aug 2026
- Binary 1 — since Jul 2026
A phone already on binary 2 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 2 build. How to read a build number.
