@westwood24 Any chance you could make a TWRP flashable for us99820d: //forum.xda-developers.com/lg-v30/development/us998-lg-v30-us998-us99820a040330-kdz-t3786337

    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

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

    Don´t forget to hit the thanks-button if you like my work! :good:
    You want to help me with a [donation?] Feel free to make it.​
    @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.

    Trying now, will let you know how I make out.

    Yup! Currently have VZ FW running with twrp, and root!!!! I will start debloating with Titanium. Sorry to get offtopic OP! Visual VM is BACK!!
    Confirmed working.
    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.
