Star Traveller,
regardless of whether you are on Apple's payroll or not (you certainly do a lot to make people think so) it would help not to play the "know- it- all guy" and to constantly patronize and instruct people about what's right or wrong. There are lots who go through difficulties with iOS8 on their units, this is a simple fact, one can see it on both english and german forums. This hasn't happened with former versions to the same extent. For those people it is no help if some have managed to get their iPAD 2 units working after a total reinstall. It would be Apple's job to inform people before ⚠ that this is what probably has to be done when installing 8.x on an older unit.
Because this is exactly what I had to do today. I finally decided to give my iPAD 2 on iOS 5.1 a try, I did it on my iPAD directly. After everything seemed ok after the upgrade I ended up with a unit that froze in reboot and was unuseable allthogether. I had to go through the DFU service mode and wipe everything/ start from scratch.
This should not happen, because iTunes kept offereing me the upgrade since weeks.
So to make the long story short, I did a complete wipe and fresh reinstall without reinstalling a backup. App after app. This is time- consuming and should be clear before. No excuse for Apple here. Bad and un-userfriendly procedure.
The good part is that in the end I now have got a well working iPAD that does what it has to, quite fluidly (only switching on "reduce Motion"). So after all I am ok with what I have got, but I am not ok with the way I had to do it. We are talking 4-5 hours here (and I am not yet done) instead of an automatic process that should happen within an hour.
