HT201412 iPad 2, ios 7.0.2; Apple logo when cover opened requiring a reset to start iPad even after system restored through iTunes. Same problem with Lock / Unlock off.

Question

This problem only started after installing ios 7.0.2 on 3 Aug 2013.  The iPad must now be switched off before closing the magnetic cover or the system freezes displaying the Apple logo.  I think the lock up occures as the cover is closed as the iPad was quite warm when I returned to use it about 2 hours later.  The battery was fully charged just prior to the upgrade, but, after a system reset to get the iPad running again, I found the previously full battery down to abt. 20%.  I have tried turning the (auto) "Lock / Unlock" off but closing and re opening the cover still reveals a black screen with the Apple logo, and the need to reset.  I restored the iPad through iTunes but the problem still remains........any ideas any one.........APPLE ???

Answer 1

Thank you for your perseverence.
Yes I am the first and only owner/user of this iPad.
No the iPad has never been jailbroken (or dropped, knocked, dunked or sat on)

Both of the above was conducted on a clean install with no backups restored.
The problem ocurred immediately after the iOS 7.0.2 upgrade. I have used the iPad every day since I got it shortly after version 2 came out and it had performed flawlessly right up to this upgrade. The upgrade was done wirelessly and the battery was fully charged. The iPad was disconnected from the charger before the start of the upgrade and no problems were encountered during the upgrade. I closed the cover on completion and that appears to be when the problem started. All subsiquent restores have been through iTunes 11.1.1.11 with no reported problems.

Both were retrieved from the iPad; Settings > About > Diagnostics and Usage > Diagnostic and Usage Data
I have also retrieved log: "2013-10-07-174832.panic.plist", but it is quite long. I expect these logs will mean something to someone at Apple.
