The wipe fixed it for me, easiest way for the apps is obviously do it through the web, I went through all my apps, selected them to install and left the nexus running for 20 minutes - everything installed.
Anything I had or wanted I drop boxed it and just dragged it back down, it really doesnt take THAT long to restore it all.
Going to sort it out soon as its charged.
You can install all the apps you have previously installed through the play store. You don't need the web. Open play store app then on the right there is a little arrow with a line underneath tap that and there is a list of everything you have ever downloaded with that account
