Well I did all the wipes set up the new Rom slot all was fine until google went to intall my backups Error Error Error installing on at least 30 Apps, I had a 2nd backup in Google drive so all ok right now..
I never restore apps from google, that's what titanium backup is fore. Letting google restore stuff can mess things up
I have never had a problem with that first time ever since I've been wiping and installing Roms. always a first I guess.
I'm thinking there is a difference between having Google restore a BACKUP and having it automatically reload APPS from the market.
Restoring a backup implies restoring settings, and that's rarely a good thing between ROMs, or even different versions of the same ROM, some times.
I've never had a problem having Google reload apps, that said, I rarely do it. Google doesn't really know which ones I want reloaded to my phone. So I always cancel the auto reload and the restore USER apps and data (never system apps) using Titanium Backup. That's hasn't caused a problem for me yet.
