Hello dbrazzell. Welcome to Android Forums. I'm very sorry to hear about your red screen. That is something new to me. I have no idea what might be wrong or how you should progress. I suspect the best place for you to start will be in your phone's discussion area. They might have a suggestion and if all else fails, they can walk you through a forced factory reset to at least get your phone working. Not knowing which S2 you own I'll leave you a list of links of all the S2 phone areas. Just follow your link and describe your problem there. I hope with the help of our friendly members we can get you back up and running.
