Apple has stopped signing iOS 11.3.1 which means that downgrading or restoring to that firmware version is no longer possible.

Currently, Apple's latest firmware is iOS 11.4 and developers have been seeded with iOS 11.4.1, as well as iOS 12. If you accidentally update or restore, you'll find yourself on iOS 11.4.

*SEP is compatible with iOS 11.4. Seems like only the iPhone X has issues using this tool.
