I just deleted everything from my external SD card, except pictures, music and of course the Carbon folder. Then freshly installed 4.2.2 JB and within about fifteen minutes I was back up and running with all of the main apps I use. The only thing though is that it installs to the internal sd so you have to move the apps back to your preferred location.
Is there a way to point it to the external sd? I tried backing up to sd yesterday and it bogged down, and then I got an error. Later discovered that it had filled the internal sd and that's what caused the problem.
I'd like to know this too. I don't have that many apps installed but I would like to avoid manually moving all my apps back to the external sd card. One solution for you though would be to restore half of your apps, then move them to external sd card, before installing the rest.
