H910 (ATT V20) oreo update manually, help needed

[Mirsaneli]

You flash all partitions for non rooted stock which should work like normal with everything working.

My guide is for those trying to keep root intact so to preserve the dirtysanta eng aboot so there are problems with data at the moment.

Could you write here the steps for just getting TWRP to apply the provided OTA Oreo zip file. I don't want root, just H910 stock Oreo Rom because I'm currently on Unlocked H91010l which is from December 2016
Your guide is very nice,but a bit confusing since I come from Samsung device where I was getting TWRP by simply flashing with Odin.

Use this to root.

Instead of flashing the 10v att image like the last step suggests, use the 20g Oreo image instead

Thank @clsA for the Oreo link

I did as you said, and now I've got the fresh Oreo LG V20 H910 (which I was never able to get because I'm outside USA). God bless you!
