Hey, I got just the solution for you!
I found this app that allows you to bypass the lock password... Mildly concerning but it works.... It's supposed to be a V10 thing but works on the v20, you can straight up get into your pics no issues.

Use the "LG V10 Hidden Settings No Root" app to access the mobile network settings AT&T (or any other carrier) has hidden on the LG G5. Change network mode to GSM/WCDMA.

I needed to disable LTE on my ATT G4 (now on 6.0) due to battery life issues. Thought it would be impossible without root until I found this gem: https://play.google.com/store/apps/details?id=you.love.v10.hidden.settings&hl=en
This app isn't v10 specific luckily. Give it a shot! Works for me.
I use the V10 Hidden Settings to turn off KnockON. (I was tired of having the phone turn on in my pocket.) V10 Hidden Settings
If you go to the play store and download this app, https://play.google.com/store/apps/details?id=you.love.v10.hidden.settings
You can change the KnockOn settings
