the -0 version I hope should be perfectly fine. not 100% certain on it though, the only difference since rc8 should be a few kernel bug fixes and a new exFAT driver, and a few extra partitions added to Flash Image page to work with the OTA 7z file I uploaded.

update: updated thread for B&H Photo V20 model US996.
Ever find a solution for the us cellular version to root?

all was fine until i got to the command "adb logcat -s recovery" after that it stopped after the first 2 lines. Looked like this (copied from command prompt window)
C:\Program Files (x86)\Minimal ADB and Fastboot>adb logcat -s recowvery
--------- beginning of system
--------- beginning of main

I tried the whole process over three time each doing the same never getting any further, any clues or help would be greatly appreciated. Thank you.

This requires the very old december 2016 security patch, which is impossible to revert to on H918's on or past 10p (yours is, since you're on oreo, which is 20 something depending on your actual software version). you need to follow a different process which is exclusive to the H918 because only the H918 can use fastboot oem unlock.

This process, which is explained in more detail here

Thank you

Thank you, I really do appreciate the response. I am yet to try the alternate method which you have so graciously presented to me. Been a little busy these past few days, but I indeed WILL mosey over to the links which are provided and give it a try. I really miss having a rooted phone and I know that the older a phone model gets over time, along with the forced upgrades the likelihood of there being a root for it diminishes greatly. That is why I have decided that when it comes time to get a new phone (whenever that might be), that the next one will be bought solely based on its ease of root-ability. That, I think will make things a whole lot easier in the future. Thank you again for all of your help. And a thank you as well to ALL of the gurus at XDA for your knowledge and expertise of the Android. Without it, I don't know who I would trust for the correct information on such matters.

So I downgraded with the KDZ to Android 7.0.0, ran FWUL on a Windows 10 Enterprise computer, got TWRP put on the Download side, Flashed Magisk, then put TWRP on to the Recovery via the TWRP app on the phone. Backed up the phone with TWRP. Verified the root with a root checking app. I am all rooted and ready to implement and enjoy all of the benefits of a rooted device. Thank you again for all of your help, I am a very happy person right now.:D

So I have LG V20 h91820h, will this method work for me? I thought that I had read that my phone could be rooted using lafsploit, but now I can't seem to find the instructions...is there any way I can achieve root on this device?
