mh, it seems I have problem with root-access.
I can obtain root-access in diag-mode but as soon as i reboot I cannot get root again...
so I fail somewhere by step 7 or 8 in '
HowTo-get-root-access 
but when I am in diagmode again, the root pw is the one I chose ...
don't know what mistake i am doing ...
so i could run the jb.sh in diag-mode, but it sounds like that's not what i want...
