It's possible that a factory wipe would fix the issue .
I always go in to CWM and clear the cache and fix permissions . It's just a habit I've gotten in to .
There was also one issue I was having when I flashed the DATA2EXT kernel that I didn't mention . When I flashed , I had absolutely no data or radio signal . The Boost Network was completely down . I don't think that had anything to do with me having to re-enable data but I thought that it needed to be mentioned . You would know better than I .
are you still running the test kernel, and are you getting signal now ?
