my phone into computer! Help!? After I rooted my phone I had trouble accessing my files from my phone. I get a error when I plug in the usb cord to my computer and phone saying mtp device failed. I have the latest drivers installed. When I rooted my phone i used a different model # from metro. My model number after root was SCH-R530M and before it was SCH-R530. I looked these up before rooting and people say its fine. The phone is fully functionable and i have no issues whatsoever. When i try to plug in the phone to my computer or any other computers I can't access my files!
