iPad Pro 12.9" bootloop

Hi!


I seem to be a bit unlucky with iPad OS 13. My newest Generation iPad Pro 12.9" is unresponsive to touches from time to time since I installed iPad OS13. I wonder if that's software or a coinsidence. (hardware problem).

But even worse, when going the small step from the previos to the current betta (what was it, build f to build g or something) my 1st Gen iPad Pro 12.9 went into a bootloop and is now basically a brick. Trying to restore it gives an unknown error -9 and I even bought reiBoot but that doesn't help either. Have both my 12.9" iPad Pros just shown a hardware issue right on iPadOS 13?
