Did the endless startup-logo-startup-logo loop continue after the 20 sec power button restart?
The endless loop started after I just powered up.
Now after the 10/20 sec power up (hooked and unhooked)..it goes to the att screen and stays there.
Just to clear it up, after you performed the 20 second power-button restart (with the charging cable not plugged in), did you hook it up again without starting the phone and
waited for it to turn on by itself? If not, try that.
Did that...went to white screen and died again...:dry
Man this hurts...a beautiful phone. Have been waiting for this for a long time... always wanted to come back since my wm6.1/6.5 days...but what a let down!! but hopefully MS and Nokia will do something soon.
