Turns out my nook needed a re-root, so I put it back to stock with CWR, and then I started over completely, and rooted her to CM7. Everything looked and felt right. Then I started to use it. Cannot load email. Get to last sign-up step and FC. Cannot load app. FC. Cannot load Dev Tools, or ROM manager... FC. Everything force closes. I know I'm going to have to wipe and start again, but I was curious about something. I read somewhere that sometimes this happens with class 10 mSD cards. Is this true? Should I wipe and start over with a class 4 card instead? Also, do I need to flash back to stock before flashing back to CM7 again? Thanks.
