I already downloaded the update of ios 5.1.1 OTA, using wifi on my ipad but when it is going to install, message occured "unable to install the update, error occured when it is going to install", can somebody help? The updated can't remove and can't be installed. It's stuck on my ipad 1
iPad, iOS 5.1
You can try to plug it into iTunes and try to do the update that way. The download might of became corrupted or it can't verify the integrity of the update. You could also try to hard reset it by pressing both the home and power button for about 10 seconds. If all else fails, wipe the iPad back to factory defaults and try the update again. Not ideal but sometimes its the only way out.
If you get a message that the update cannot be installed then it will never be installed. Start iTunes on your computer, connect your iPad and install the update that way.
