Restoring of iPad using recovery mode fail due to 15 minutes timeout
This constantly happens to me and people I know.


Download the .ipsw file - links to true Apple Software are listed at https://ipsw.me
[files hosted by Apple, the site simply makes the files findable, as Apple doesn't publish the locations]
Place the file in ~/Library/iTunes/iPad Software Updates or ~/Library/iTunes/iPhone Software Updates depending on device.
Launch iTunes &amp; connect your device
The ipsw ought to be discovered automatically.
Follow the on-screen instructions


ipsw.me has links to all iOS versions, however generally only the latest is still being signed by Apple &amp; will therefore be the only one that works for a restore.
