Thanks Jazante for the tip - I tried everything - did NOT work. So I am really desperate - since 2 month now these funny Apple Developers ruined my Ipad. Can anybody can give me a hint, how I can get my iPad back working? Any hint very much appreciated!

As Apple is making us all "happy" with converting our ipad into a brick or a paperweight, can anybody advice me, to return to a howsoever working ipad? Thanks!
