How to fix some mysterious problems.

My iPad Air, which has been treated with kid gloves and is in mint condition, won't turn on at all after the latest Cydia substrate update. I even tried holding down the volume up button to disable mobile substrate. It won't work. I had the latest version of Cydia that said that I could put a passcode back on as well. I can't get iTunes to see it even in DFU mode. Anyone else have this issue?

Just to make sure you are doing the no substrate mode correctly. Hold power and home buttons, screen will go black, once apple appears, release both buttons and hold volume up button until you see the lockscreen.

Yes I've use that exact procedure several times and can't get it off the Apple logo it's not in a boot loop it just shows the Apple logo on the screen and it stays there. I just tried that method again and was holding the volume up button for at least three minutes still nothing the only thing that happens is the screen slightly dims. I can put it into DFU mode and recovery mode but my iTunes would not recognize it to hit restore. So frustrating because it was working perfectly.

Thanks, perhaps I didn't remember to reinstall Cydia 1.1.15 after the restore from backup? iTunes at work recognized DFU mode instantly. RESTORED, REJAILBROKE & REBOOTED!!Thanks again justinred!
