Thanks for your response Chazz.
I used adb to reboot to recovery, and of course there it was. Flashed magisk, and I'm back up rooted.
Just FYI... I did not flash the two extra files, and twrp is not giving me any trouble.

Ah, here's why... @westwood24 include that, it seems:

Features
*Stock build made from official KDZ
*Stock Build.prop
*Unrooted
*Boot.img modified to keep TWRP
*Remove dm-verity
*Remove forceencrypt

So, in flashing this with TWRP, you just need to reflash Magisk for root.

I'll edit my previous post to correct that you only need to reflash one file, not three.

I've been reading people losing root, TWRP etc.. So basically, just go into TWRP and flash? Then I won't lose anything? I think I rather clean flash anyone have issues not dirty but clean flashing? Thanks in advance!
The mistake I made was not flashing magisk zip before booting to system after flashing update zip. Had I done that I would have had root without issue. Still happy however, as I updated to 20b without having to lose my data.
From what I've read, most are having no issues at all with clean flashing.

and you can still take a twrp backup? as in, you dont have to format the memory to get rid of that encryption pw?

Hi, somehow, according to SGCMarkus at least, I've managed to re-encrypt my storage/ data after reflashing magisk, he says it was probably because I had the "preserve force encryption" option checked on the main page of the app. His last suggestion to me (https://forum.xda-developers.com/lg-v30/development/unofficial-twrp-3-2-1-t3779171) was to flash no-verity-opt-encrypt zip to decrypt data partition, but that zip hasn't been updated since november of last year, and it didn't work anyway as I expected.
Last thing I tried was to reflash this oreo rom again, since it has Remove dm-verity / Remove forceencrypt built in, but that still didn't remove encryption. Idk if it's because I need to wipe before installing, but of course I am unable to wipe or backup due to the encryption. Is anyone aware of an updated no-verity-opt-encrypt zip that I could flash separately, if that would even work?

Everyone else flashes that "no encryption file" when they unlock their bootloader. TWRP doesn't play well with LG encryption... Doesn't matter when the file was last updated. It works. ;)

Right, yea as did I. So when you refer to the "file" are you referring to the no-verity-opt-encrypt file? If so, could you maybe give me a tip on what I might be missing? I've flashed this zip twice to no avail, still getting encryption screen at launch of twrp, as well as not being able to perform backups or wipes. Thanks!

Yes, that's the official name, but basically it's supposed to turn off LG encryption. However, when you unlock your bootloader, your internal storage is already encrypted. So after flashing that file, you then have to reformat your internal storage. Not just "wipe", but the one where you have to say "yes". However, don't reformat the OS or you won't have anything to boot to.

Suggestions? Sort of start over. Maybe reinstall TWRP, make TWRP writeable, flash this file as well as the "no check root file", then reformat the internal storage.

I just flashed the 20d kdz (LGUP). Had issues with twrp had to reflash twrp.img in ADB along with magisk and the other two files. Sounds like you will have to start from scratch like Chazz suggested. That's a pain but at least your bootloader is unlocked.:good:

Thanks for the suggestions. If you saw the next post down, someone had suggested formatting data, which was an option I had completely forgotten about, which did remove encryption and essentially allow me to start over.
My problem now, and this is getting off thread topic I know, is that the magisk flashed with boombox rom, was corrupted once again (errors on flashing module), like before. So I once again, reflashed magisk uninstaller zip, but again, as before it re-encrypted my data...wtf. So yea I've posted on the magisk forum and hopefully will get a solution to that.

    LG-US998 20B ROM​
    Hello everyone

    This Rom is 100% Stock. TWRP 3.2.1-0 must first be installed as with Nougat Roms. Then you can install this Rom and have Oreo with working TWRP.

    This zip is created from the original KDZ. I changed the Boot.img, so you do not have to reinstall TWRP. . . ;)

    I had made this for users who can not get ota's because they have Custom Recovery / Root installed

    Sorry for my bad english i'm out of practice :p

    Features​
    *Stock build made from official KDZ
    *Stock Build.prop
    *Unrooted
    *Boot.img modified to keep TWRP
    *Remove dm-verity
    *Remove forceencrypt​
    Installation​
    What you need​
    *Unlocked Bootloader [How to do]
    *Working TWRP installed [Link to unofficial TWRP]
    *When you need Root, Latest Magisk [Download]
    *US99820B(TWRP).zip [Download]
    *GDrive Mirror US99820B(TWRP)[Download]



    How to install​
    When you are on Nougat: Reboot to recovery using button combo or reboot app (need root)
    flash this TWRP.img Download reboot and Backup Dalvik,ART, Cache, System & Data (include not your internal memory) and Boot
    in to your external sd or copy the backup from internal sd to your PC!
    From Oreo: Install TWRP with this guide but with this img
    For clean install: Wipe Dalvik/ART, Cache, System and Data (Recommend)
    You can also keep your data by dirty flashing the zip. *Not tested!!!*
    Flash US99820B(TWRP).zip
    then Magisk zip when you need root
    Reboot System


    At the first time you boot to system, it can be TWRP says No OS installed. You can ignore it.
    If TWRP asks if you want to install SU, hit no



    Here you can find my other [Downloads.] There are IMG´s, KDZ´z and more!

    @ChazzMatt Absolutely correct sir, I was a "little full" of adult beverages at that early time of the morning and should have NOT been playing with the device at all. :cyclops:

    I believe I unchecked boot and recovery in the partition DL choices.

    Magisk version? With 16.6 beta there are many problems on my h930

    I'm using v16.0. It flashed fine through TWRP after I rebooted the system. :good:
    I was upgrading from US99820a to 20b. I haven't had any other issues to report.
