Samsung Galaxy XCover7 Pro (SM-G766U) Firmware Overview
What is the latest SM-G766U firmware?
G766USQUADZJ7, released October 21, 2026 with Android 17. It is a feature update on bootloader binary 10. The archive holds 25 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 XCover7 Pro 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.
Which Android versions did it get?
The SM-G766U builds in the archive run Android 16 to 17. The earliest build we have for each version:
- Android 17: G766USQUADZJ7 (Oct 2026), 1 build in total
- Android 16: G766USQU7CZE7 (May 2026), 24 builds in total
Can I downgrade the SM-G766U firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 7 to 10:
- Binary 10 — since Sep 2026
- Binary 9 — since Jul 2026
- Binary 8 — since Jun 2026
- Binary 7 — since May 2026
A phone already on binary 10 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 10 build. How to read a build number.
