Before starting take a backup of your files (if you want)
So let's go on..!
Go here and select the first one.
Then go over here
And scroll down to "How to flash ROM kdz method"
Enable usb debugging
Connect your phone to your PC
Download Lg drivers(Not Verizon one's!)
Download Lguptool, unzip it,open the folder and inside of it where all the lguptool files are located move the kdz file that you downloaded.
Open lguptool with admin prompt!
Select type CMDA and phone mode DIAG
Select the kdz file and click "CSE Flash"
Then click "start"
A menu will appear,select language and click "Ok"
After all these steps you will need to wait till the phone boots.
Then you will be able to root your phone and flash ROMs!
(A "thank you" would be really appreciated!)
