Apple usually releases iOS files ending with IPSW file extension. For developer versions of iOS 7, it is a different case. All of the developer files of iOS 7 are released in DMG format.
Say, for example, you have recently downloaded iOS 9 file on your Windows 8 computer. And if It’s a DMG file - you will not be able to run or open this firmware because DMGs work only on Macs. You have only one option: to convert the DMG file into .IPSW format.
You simply cannot remove “DMG” extension from the file and replace it with “IPSW.” It doesn’t work that way — I have tried renaming DMG to IPSW extension which resulted in nothing but a waste of 25 minutes. Here I will share my top tools I use for converting files into IPSW format.
