Recently I've had my iPad hang. It hung for so long I decided to restart my iPad so I held the sleep button and home button until it restarted on its own.
Upon restarting, the Apple logo displayed as per usual and then came the iTunes logo and a picture of a USB below pointing to the iTunes logo. I assume this is the recovery mode. So I proceeded to click "Restore". It started downloading the update and went on to restore my iPad.
At the end of the restoration then came the error saying,"The iPad "iPad" could not be restored. An unknown error occurred (40)."
This would not be a PC issue as I tried restoring it from my laptop which failed and so I tried it on my PC which failed as well. My network is also not the issue as I am fully connected to the internet with no issue syncing my other Apple devices and updating etc.. And since I have been able to sync with no problem (both on my laptop and my PC) for my other Apple devices, I strongly believe that it is not an issue with my security software.
I've read somewhere on the internet saying,"..due to out-of-date or incorrectly configured security software". Could it be that some part of the software on my iPad that saves the date stopped on that very day when it became "bricked"? And that now it is another date and that conflicts with the part of the software that uses this information? Would it help if I changed my desktop's date and try again? Please understand that at this point in time I've tried all I can and frankly am frustrated already. So I would like to know if it would work before trying.
So I've decided to make a trip down to a local Apple authorised service provider to see if they can fix this. They have stated that it is an issue that customers face and that some can be restored and some can not be restored. They then tried to restore for two times and concluded to me that the device is unable to be restored. They went on to offer me a 1-to-1 replacement where I would have to send in my current unit and pay a fee of S$400++ to have it replaced for a brand new iPad version 1 with the exact same specifications.
Tell me frankly and honestly that this offer is genuinely a good offer and I will take it. But take no offence; who in the right mind is going to pay 400 bucks for a device that is two generations backdated.
The apple authorised service provider also stated that the problem with my iPad was that of a hardware issue. I have no dropped it a single time, I have not ever used it until its burning hot, and there isn't a single tinge of a burnt smell coming off from it. If what they say is true then I have to say I'm a little disappointed in the lifespan of this iPad. And the standard 1-year warranty is definitely not fair for a product like this. You have to agree that in a mass production no matter how careful or accurate manufacturing machines are there are bound to have issues that may have produced a compromised product.
So here's a quick summary of the things I've tried:
- opened iTunes, connected device, set to DFU mode and tried restoring.
- tried with a laptop, PC Desktop.
- tried with a different 18 pin USB cable.
- tried self-diagnosing the issue after reading your troubleshooting page,
iTunes: Specific update-and-restore error messages and advanced troubleshooting
- delete the iOS software file (.ipsw) and retried restoring again.
- sent to an Apple authorised service provider located at,
eServ@313Somerset by Micro 2000 Technology Pte Ltd (6.5 kms)
313@Somerset (Somerset MRT), #B3-22 (Beside M1), 313 Orchard Road, Singapore 238895
All of which ended with a disappointment that my iPad died out of the blue and is now still unable to be restored back to factory settings.
