I have the same issue and I'm currently making a new topic for it (Lazar asked me to do this after I first posted to the ticketing system).
A friend and I managed to hack into the omega by interupting the boot sequence an replacing init with sh. Then we were able to see the crypted password, wich in turn googled to the string '5up'. This seems to be the OpenWRT standard root password.
So try to log in with: root & 5up
