Had to take it to the job center where, it was downgraded to 4.0.4 (have still to check which flavour) fixed something and Wiped everything. When I side about he post mortem backup and the intention to try a restore from there I was give an are you kidding look, it could crash again... sigh.
Anyway thanks everyone that spent some time to try and explain a noob how to try to solve this issue.. Now I've got a new galaxy nexus, so after a little grievance I'll start reading on how to flash a nice rom...
