Well, did my first Nandroid restore. lol
Not sure what happened. I did a full Titanium Backup, booted into recovery and did a Nandroid backup, then wiped the data, flashed SuperD, rebooted, signed in, did the Titanium restore, then booted into recovery and flashed a theme.
Fully booted, and there was no lockscreen, the home and search buttons didn't work, and Screebl was completely inop. Multiple reports of "my home button doesn't work anymore!" in the SuperD thread with the only suggestion being "wipe and reinstall" weren't encouraging, and doing the "fix apk uids" command from recovery didn't help at all.
So I gave up. Maybe if I HAD wiped and reinstalled it would have worked, but I was about to have a panic attack; plus it was a clean install, so how would another wipe and install change anything?
Plus the theme's boot animation was the Droid logo, so that annoyed me.
Thank the FSM for Nandroid. lol
I'll try again with that or another rom some other time.
