I recently rooted my LG Optimus ME, also known as LG P350, and it was working perfectly fine. After I installed some apps (I think), the camera stopped working. It came up with an error/notification: Code: Failure to start Preview whenever I start up any Camera application. I have searched on this, and I have found little information on this problem. I saw that I would have to "reflash" my phone. If not, how would I fix this problem?
