I unplugged my iPad at 25% charge and used it. Suddenly my iPad froze at 19%. I rebooted it by pressing both home and wake/sleep button. It was stuck on the booting-up screen so I decided to charge it. After plugging in my iPad for 30 minutes, I came back to check it but then it was turned off.
After that, I turned on my iPad but after the apple logo appears, the screen goes black. I tried turning it on again but it just repeats the cycle. I already connected my iPad to iTunes to the PC to recover and restore it but still it won't turn on; it just keeps showing the Apple logo then black screen again.
What should I do? Does this need a reformat?
