Default [Q] Android Brick boots only into recovery

I've a Runbo X5. It has a normal Android 4.0.4 system I haven't changed anything on it. Now a friend of mine used too many pattern attempts so that my phone got blocked and I had to log in with my google account or something. Nothing worked and after I switched the phone off it now only boots into recovery and I get the dead android with the red triangle. I already tried to delete cash, factory reset the phone and rebooting it but still the same. If you need to know more about the phone its all written here:

What can I do now? Please help me.
