[LG V30 Questions & Answers] ChazzMatt:
I followed those instructions exactly (posted below) and got a message saying "there are no update errors that can be recovered."

No image file ever appears. LG Bridge does NOT download anything. But it does "restore" my phone using my backup files on the PC.

When I go to Software Update and click on Update Error Recovery, it basically tells me there's no errors to recover or that can be recovered.

Here's my log file from this folder seen below. I swapped out my PC user name for generic "user name" for the purposes of posting this publicly. In the REAL log, it shows my user name.
