[GUIDE][ROOT] How to Root your LG Optimus 4X HD (O4X P880)

I would like to begin this post, by saying that I did not come up with this method, but wanted to get it written up as a proper thread as soon as possible for people to start enjoying root on their phones!

This method was tested successfully by me on an EU phone running V10D. I am not responsible for what you do to your device after reading this guide. You undertake any actions at your own risk!

If you want to thank someone, please thank qaz753 who posted the method for this here.

All files needed are attached. (If certain files are not permitted to be attached, MODs please excuse and PM me, and I will look into hosting them myself)

GUIDE
Download, Unzip and Install the LG USB Driver.
Download and extract the HTC One X Rootkit (onxr.zip) to C:\onxr
Download and copy IS11LG_SystemBackupTest.signed.apk to your phone
On your phone, go to Settings -> Security and make sure "Unknown Sources" is TICKED
On your phone, go to Settings -> Developer options and make sure "USB debugging" is TICKED
Install IS11LG_SystemBackupTest.signed.apk
Open IS11LG_SystemBackupTest.signed.apk
Hold the power button and choose "Power off and restart".
When you can see the lock screen, you may notice that the phone is running very slowly, this is normal.
Connect your phone via USB to your computer.
Open a command prompt (may need admin privelages, right click, run as administrator)
Type without quotes "cd C:\onxr" and press enter.
Type without quotes "root" and press enter.
Wait while the script runs, and the phone will reboot automatically 3 times.
You should then return to the command prompt (C:\onxr>).
On your phone, open up Google Play Store and search for "SuperSU".
Update SuperSU then open it.
Press OK to update the SU binary.
You now have root and can safely remove the "SystemBackupTest" app, and restore the "Unknown Sources" and "USB debugging" settings back to how you had them!


The root kit and apk may contain other peoples work, I did a quick search to try and find the original sources but to no avail. If this is your work, please PM me and I will be more than happy to add your name to this post and give credit where its due.


HAVING ISSUES?
Try disabling any Anti-Virus you have running
Uninstall or disable any screen filters/adjusters
You can safely re-enable and re-install the above once you have completed root
