Why I mentioned it was the H910. I don`t remember why, but among the
unlocked models for the LG V20, I decided the AT&T model H910 was best.

Of what I read of attempts to root and unlock the LG V20 H910, and
replace the OS, there were problems afterward. Was hoping someone knew
of a best method and replacement OS that didn`t end up bricking the
phone, or losing hardware support (i.e., end up with a retarded phone).

Yeah, interest in rooting and OS replacement for the LG V20 faded back
around when LG dropped support in 2020. The phone was introduced in Oct
2016, I got it sometime in 2019, managed to get 2 OS updates before LG
dropped it in 2020, and then LG left the smartphone market in July 2021
after 23 consecutive quarters of money loss in the mobile division.
There would never be any OS updates for this phone after they
discontinued support, and especially after they quit smartphones. They
tried to sell off their mobile business, but no buyers.

In one of those forums, and in online guide articles, one of the first
steps to check was Developer Options had "Enable OEM unlock". It`s
there in my phone. It is an early step, if not the first, in prepping
to replace the OS. I don`t just want to root the phone since the old
Android 8.0.0 would still cause problems or loss with many newer apps.
Rooting was just a preliminary step, not the end-all step. Need to
replace the OS with something newer to move forward with app
compatibility.
When I attempt to enable the unlock, I get a warning "Warning: Device
protection features will not work on this device while this setting is
turned on." Okay, something else to research: just what is device
protection. LG describes this:
https://www.lg.com/us/support/help-library/lg-android-device-protection--2015010
3626155
For now, and until I decide to make this a test phone, I cancelled the
proposed changed, so the unlock remains disabled (the default). From
what I`ve read, so far, that its bootloader is unlockable does not mean
it is a simple or even straightforward task. One mistake, and it`s
toast.
I`ll go digging in the XDA forums some more, but the more I read the
more I see mention of hardware loss (i.e., hardware not supported or not
completely supported by the replacement OS). Prognosis is not good.
New phones are just ridiculously overpriced, especially when trying to
find those that have 6-7 update lifecycles.
