Two issues, 1)After rooting my LG E739 to CyanogenMod 9, ICS, there is no sounds coming out. I tried YouTube, phone calls, notifications, and music with maximum volume, it still doesn't come out. 2)When i tried to connect my phone to my laptop using USB debugging (i also enabled USB Mass Storage), it does not show up in my computer, and the troubleshoot and it says "MTP USB Device has a driver problem" can anyone help me??? thanks!!!!
