My phone says update in process but I see no signs and the Language Pop Up hasn’t occurred yet. Any ideas?

I get confused.

At step 6, why don’t you press “Start Upgrade” instead of “NORMALL WEB UPGRADE TEST”?

The phone will be fashed with the KDZ selected or from the web in LG Mobile Support Tool?

What i do not realize is in truth how you are now not actually a lot
more well-favored than you might be right now. You are
very intelligent. You already know thus considerably in terms of this topic,
produced me individually consider it from so many numerous angles.
