Hello, my Ipad 4th Generation would go to the Apple Logo screen and won't boot-up. I went into DFU mode to reinstall the iOS through iTunes which restores and updates. In the process while doing this, I get an iTunes Error 9 Message. Browsing through countless forums, I found it to be a problem caused by the USB cable, so I went out and bought a new cable and it still didn't solve the error 9 problem. In the process of updating, I noticed that my iPad would turn off abruptly during the update process and afterwards it turns off, the error 9 message appears on my computer. I've tried it with multiple computers and it still yield the same results. I'm looking for a way to manually reinstall the firmware and then iOS since something seems be wrong deep within it and I think its a software issue rather than a hardware issue. Any thoughts on this? Many thanks for your help, I appreciate it a lot.
