Samsung Galaxy XCover7 (SM-G556B) Firmware Overview
What is the latest SM-G556B firmware?
G556BXXSIEZH2, released August 5, 2026 for region GLB with Android 16. It is a security update on bootloader binary 18. The archive holds 3 official builds for this region.
Is the Samsung Galaxy XCover7 still getting updates?
Yes. The newest build is from August 2026.
Can I downgrade the SM-G556B firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 15 to 18:
- Binary 18 — since Aug 2026
- Binary 17 — since Jul 2026
- Binary 15 — since May 2026
A phone already on binary 18 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 18 build. How to read a build number.
