Install LG Drivers before connecting phone to computer
Connect your phone to your computer with the USB cable in each mode (MTP, LG Mode, etc...) and allow the drivers to install.
Put the phone in LG Mode and flash KDZ V20F. This will give you the T-Mobile USA JellyBean ROM. Has all the same features as the MetroPCS ROM except different bloatware. (TMobile account stuff rather than MetroPCS)
Install LGPwnapk and follow the steps (Starting at Step 15).>> http://www.droidkube.com/how-to-root...timus-l9-p76/#
This will root your phone.
Install BusyBox and SuperSu
I recommend installing PimpMyROM from the Play Store. Has lots of great tweaks like improving battery life and speed of device. Battery life is notably longer for me.>> https://play.google.com/store/apps/d...uide.pimpmyrom
Use "SD Card as Internal Storage" script, attached below. Extract the file and run it in Script Manager "as a Script" with "SU" and "Boot" and reboot your phone.
