Big problemo! Hi for all ya! I have a BIG problem! I have a Lg Optimus Black and i root it with Gingerbreak. But...i thing i have uninstall some sys app because when i connect the phone to pc it is not working. I think I accidentally deleted an app but I do not know which one. Because at some point my phone move very hard when I delete the apps and in the some point he asked me 2 times if I'm sure to delete the app. And do not know which app is for USB mass storage. But i`m not sure. My pc says that the usb device connected can not be recognized by Windows (XP) I found a app: Root Toolbox. The menu has submenu "Mount" and when I squeeze it shows "USB Mount Option". Here i found: SD Dual-Mount, Unmount SD from PC, Dual-Mount EXT,Unmount EXT from PC. Does it help me? Please hepl me!
