iPad Air 2nd Generation - Error 9
I backed up my iPad to iTunes after not having done so for a long time. After, I attempted to update to latest software version and failed. At this point, I can't get past the Apple logo with a grayed out progress bar due to Error 9. I've attempted Update and Restore and failed. I've switched USB ports - no difference. I can't get the iPad to start up without asking me to connect to iTunes. It was working fine before the backup to iTunes. Any suggestions appreciated.
Coincidentally, I had just purchased a newer iPad air and gone through the installation process prior to attempting the update on the old one. I'm not sure if that factors in.
Thanks,
Eddie
