Well I was trying different things (a little towards root and a little for some type of unlocking) and installed RSD Lite; well as soon as I installed RSD Lite I lost the "usb mode" pop up in the upper curtain (the pull down menu on the phone). I can still access the phone via ADB, but I competly lost the USB mass storage option. Tried with and without USB debuigging on, uninstalling RSD Lite and even going back 2 months on a restore point; still nothing. I still have adb so it is not that big of a deal; I just now have to unmount and remove the sdcard and use my old card reader to access the files on my sdcard using my PC. After searching for a few hours, I can't find a solution, so hopefully someone here does. Any ideas?
