i doubt your box is broken i saw your thread in the main forum. Sometimes flashing can be a problem it usually comes down to something blocking the network. I see your pc is a dual core this can cause problems i'd try with another pc if you have access to one.
Kein system is not the end of the box, it just needs flashing again with another image make sure its 2x image if its a nokia. Most likely reason for kein system is cos you probaby flashed a 1x image on your box if its a nokia. What make is your box anyway.
If you post back with your exact error messages I'm sure someone will be able to help. The Kein system error can be a nightmare but it only means that there is no image on the box. All the solutions will be known so just let us know where you're up to.
