You have to unroot. Then install the update via ota. Then re root.

It doesn't matter. The easiest way is to connect it to your pc via LG Support Tool which will update your phone regardless of your root/unlocked status.

And you are 100% sure that it works? Did you also do that?

No, I'm just wasting my time giving bogus assistance to people.

Of course I am sure it works. I've done it before as many other users in the past.

If you already have the latest kdz file, you can do it in a quicker way by using the flashtool but it sounds like you're new to all this.

You can unroot & update via OTA or use the support tool which will download the updated firmware and install it for you regardless of your root/unlocked status as I've mentioned before (select Update Recovery).

You won't lose any data or settings. It's like dirty flashing a custom rom.

If you're unsure about using the support tool, why don't you just unroot and update via OTA? Like I said above, if you decide to use the support tool, select "update recovery" (your phone should be connected as LG software usb mode). It will put your phone into a download mode, download the latest firmware (1.6gb), and proceed with the installation. If you choose the OTA method, the download size is much smaller.

Ok im now confused. When i want to install it via ota update i have just to unroot the phone, because i read that if you have an unlocked bootloader it will stick in a bootloop? So i have to go in supersu and click full unroot and install the update and re-root and the unlocked booltloader doesn't matter??
And via support tool: i have to connect the phone to the computer and download the full firmware and i don't lose the data, is it right? Sorry for this stupid questions but i have no idea.
