hi everyone,

I updated my iPhone 5 from ISO 6.1.2 to 7.1.1 via iTunes by restoring and it was working fine but when 7.1.2 update came n I was trying to install via wifi, it failed a lot of times. so I connect my iphone to iTunes n tried by restore iphone, during this my phone was restated and it never showed up on iTunes so I disconnect iphone, since that time iphone is in recovey mode, now whenever I connects iphone to iTunes, a msg pop up on iTunes "iTunes detected an iphone in recovery mode. You must restore this iPhone before it can be used with iTunes." so I click on and then I click on restore and update. it goes for Extracting Software> Restoring iPhone software>verifying iPhone software>restoring iPhone firmware but never completes, a msg comes on iTunes iPhone restore failed. unknown error(1) I does the same like I m putting a link from someone for iphone 5s.

Check for hardware issues

Related errors: 1, 3, 10, 11, 12, 13, 14, 16, 20, 21, 23, 26, 27, 28, 29, 34, 35, 36, 37, 40, 1000, 1002, 1004, 1011, 1012, 1014, 1667, or 1669.

These errors mean that your device or computer may have a hardware issue that's preventing the update or restore from completing.

Check that your security software and settings aren't preventing your device from communicating with the Apple update server.
Then try to restore your iOS device two more times while connected with a cable, computer, and network you know are good.
Confirm that your security software and settings are allowing communication between your device and update servers.
If you still see the error message when you update or restore, contact Apple support.
