Yesterday before I left for work I plugged my iPad Air in to charge. I use the stock Apple cable and power adapter. When I returned home I noticed the iPads screen was on and showing the apple logo. Turns out the iPad has gone into a constant reboot cycle. It flashes the Apple Logo for a few seconds then a blue screen then goes blank before restarting. Attempts at a reset by holding down the Home and Sleep buttons only cause it to reboot and go into the reboot loop again. After that I tried connecting it to iTunes and managed to get it into recovery mode. After trying multiple times on multiple computers , I continue to get a 4013 error. The iPad makes it all the way to the point that the progress bar shows on the screen then goes back into its reboot loop and I get that 4013 error. I have tried every method I can find online and my warranty expired on 11/9/14. Apple wants $334 to fix what was probably caused by their own software. Any an all help or suggestions are greatly appreciated!
