I read many things once again, I even tried to save it from another computer (copy image %appdata%\Microsoft\Microsoft phone update), but still have the same problem. The startet updated and now I always get an error of 61%. So I started to pick it up in zune (settings, updates). I have read and tested many, not even the Microsoft Update tool could help. so I have the phone an inexplicable I tried again, without success. After the third update (for the WiFi issues, I think it was the 'last' wp7 update) I get an error. He had a very old firmware, not mango even, so I started updated by zune. Hello, my 'new' coming Pro arrived yesterday and I just started to test. Meeting place for Dell Pro Update failed, recover it without success
