Unable to Install 5.1.1 Update

iPad 2 renders, "An error occured installing iOS 5.1.1."

It is fully charged. I have tried using the charger when updating. I have also tried wiping it, but it still fails with the same error.

In Diagnostics and Usage, the log shows, "Closest marketing capacity entry for padding was 16GB however this device is 1GB, this might not be optimal."

Toward end of log, "2ff84000 : boot partition (required/actual): 24345562 / 52428800"

"2ff84000 : failed to create boot partition for update"

I can't find any usable search results for any of these log strings. This is a 64GB iPad 2 showing 53.8 GB available.

Thanks for any help.

iPad 2, iOS 5.1.1, 64GB

Did you try to connect in recovery mode and restore?

iOS: Unable to update or restore

Did you try to update over the air?

After I wiped it, yes. I also tried the update before and after I restored with no success.

As for over the air, the log file is titled, "OTAUpdate-2012-05-21-02-40-50.plist", so I think that's how it's trying to update. I didn't manually download it. It just showed up in my General - Software Update section of Settings. Is there another way to update that I should try?

See if you can update the old fashioned way, by connecting your device to the computer and downloading and installing the update via iTunes.

"The old fashioned way" seemed to fix my problem. I had forgotten that you could update manually! <Sheesh!> Thanks!

Just found this thread on here. I had the same issue a few days before you did (guess that's why I couldn't find anyone else with the same problem back then). The way I fixed it was having to use iTunes to update, but I suspect you'll have the same issue when updating to iOS 6.

Here's my thread, I'll post in there once I have an update:
