You probably know some people who have updated to iOS 7 beta 1 as soon as it was introduced to developers and news sources reported that anyone was able to install this newest firmware without UDID registration and dev account.

One of my friends has upgraded to firmware version 7 and he then wished to restore this beta with DMG file but failed. He was using Windows system so I searched for the fix to this little issue that annoyed him. The solution was found pretty soon and it was so easy that it would have been a crime if I don’t share it with you.

A lot of PC users faced this problem. They downloaded iOS 7 beta 1 file, tried to install or restore to this firmware and failed. The DMG file has been developed to run on Mac operating system and not Windows OS.
