Angry [Q] Can't Update Rooted and TWRPed G2 through LG Support Tool

Hello everyone,

I rooted and flashed TWRP but now i want the OTA update and i can't get it ...OTA style. So i tried with LG Support Tool.

It's checking Windows version, phone version, moving to the next "tab" , showing the progress bar for a milisecond with some "?????" as the name of the file and then i get this thing:

Any ideas?
