I rooted my Exhibit 4G and removed some apps (I guess one too many). I lost all system sounds. I decided to do a factory reset to try to fix this, and it seems to have made things worse. Now when I try to download from the market, I get "process(dot)android(dot)media" errors. I think I need to go back to stock. Problem is, I can't find a stock rom. Can anyone help, please???
