Recently they have given me an LG G2 and after a few weeks of use I am about to root the terminal, so I'm going to make you a little guide for those of you with any questions or afraid to do a step by step guide of what you have to do.
First of all notice that I am not responsible for any damage you do in your phone by not following instructions, if in doubt ask before correctly.
Unzip the zip on your pc and within an installer that are the drivers of windows phone and a folder called "ioroot25" containing the necessary files to the root appears.
2 - Activate the phone in airplane mode and development options mark the "USB Debugging" option, if you do not know that I speak continue reading below, but continue to point 3 once activated.
To enable USB debugging we go to the following menu: Settings> General> About phone> Software information> will press repeated times over "build number" until you tell us a message we have enabled developer options.
Once this is done we will go to: Settings> General> Advanced> will mark the "USB Debugging" option and continue to the next point.
3 - Install the drivers included in the zip that you have downloaded in step 1 is the file "LGUnitedMobileDriver_S50MAN310AP22_ML_WHQL_Ver_3.10.1.exe".
4 - You connect the USB cable to the phone to the computer, if me ask you select "Charge Phone".
5 - In the folder you have previously downloaded "ioroot25" in and run the file "Root.bat", you will get a window of MS-DOS, press any key and the phone reboots itself and will go into recovery mode with keys phone volume seeks the option "Apply update from ADB" and hit the button to turn off / on once again now press a key on the computer and the phone started rootearse.
6 - When finished you will have to select the "reboot" option on the phone and you will have your phone I rooted! easier than it looked right?
