Somehow my flash plugin got disabled. Can't play youtube anymore. Asks me to update flash player. The only thing i have changed on my device was loading becomeroot and then changing the root and user passwords. It doesn't seem like this would have affected it. Any ideas how to reenable?

First check that the plugin is not disabled in browser. There is a menu in bottom right where you can easily disable or enable it. I think that flash player could get disabled somehow without user disabling it.

problem solved. Thanks!
