I ran into some major issues with a rom install, so rolled back to a backup all the way back on 1.54.651.8. Now I've got constant crashing of anything and everything to do with Google apps. I'm getting a Google Services error, and all Google apps produce 'Unfortunately X has stopped' messages along with crash on launch for each app. Any ideas on a potential fix or way to start diagnosing the cause? It's making the phone basically unusable.
