I bricked my Gpad once but LGMobile Support Tool does not help at all.
This tool might work to most LG Device
Be warn the KDZ that your going to use will be auto deleted so make another copy
LG does not want us to use KDZ so we must install it offline.
Please temporarily disable any Adblock addon in your browser and I recommend to check your host file
Delete the LG Mobile Tool folder (STUPID)
Show Hidden Files in Folder Option
Replace it with one in the attachment
Then place all the Updater Offline in a single folder (very important)
Read the Instruction: it comes with link to know more about it.
Your Anti Virus may warn you about http.exe but its just a server to fool the Software updater (Use by the script temporarily until the end of the process)
The script will automatically guide you to the end
God Bless to the person who made this
So please LG don't to be like Apple.
This Lock Bootloader, Lousy Sofware Updater, Harder to Root. For what? To make people hate your products? So please stop what your doing and let people enjoy it.
