#1: Did you restore system data too? Only restore downloaded applications, then go through and bring back data to a few of the system apps. I've had that problem before, and it comes from restoring everything. When the bars are grey, it also can't connect or fetch data in the background. That should be fixed if you reflash and don't restore everything! #2: I believe it's just running the stock 4.04 kernel with explains why there's no voltage or OCing adjustments. #3: I rarely if ever use the browser any more. I'm totally now on Chrome. I haven't had any problems with it, and haven't had any problems with the browser when I do use it!
