If you are running 11.3b10 and you don't want to lose your recordings, then I would try other things and leave re-imaging as a last resort if you can't break out of the guided setup loop.
Are you still stuck in a guided setup loop? If so, can you tell us what postcode are you putting in for guided setup, and where are you?
You might want to try guided setup again while you are waiting for suggestions for us, in case it comes good by itself after a while.
