For bootloader unlock purposes, use the US998 KDZ versions with pre-July 2018 security patch: I recommend 20a or 20b.
Look at the names for dates in the title. You can always update to newer firmware later, AFTER bootloader is unlocked. Flashing a newer KDZ will not relock your bootloader. See bottom of post for instructions on how to downgrade to earlier firmware.

Flash the "ROM" with latest TWRP, after wiping caches. Reflash Magisk immediately afterwards, before rebooting to system. It's just stock KDZ but in TWRP-flashable version. Not debloated nor meant to be updated in the future. It's just a very convenient mechanism to have newer stock firmware instead of using dev patched LGUP to flash partitions, etc. Go to this thread and thank him.

Screenshots below are for previous firmware and only demonstrate how to upgrade full KDZ using LGUP.

NOTE: This is for all V30/V30+/V30S US998 -- open market US998 V30/V30+/V30S, as well as U.S Cellular US998 V30/V30+.

Here's how to flash:

Here's my own US998 V30+ updating:

----------------------------
DOWNGRADING ANY LG V30/V30+/V30S TO EARLIER OREO KDZ FIRMWARE

1) Go into download mode manually (power off completely, then hold volume up button while plugging in USB cable)
2) THEN open patched LGUP and flash pre-July 2018 security patch OREO KDZ to DL PARTITION. In the pop up box "Select All". Use the attached patched LGUP in this post.
3) Master Reset (post 101 of Frankenstein thread)

(For bootloader unlock purposes, use the KDZ versions with pre-July 2018 security patch: 20a or 20b.. You can always update to newer firmware later, AFTER bootloader is unlocked.)
5) DONE.


Here's how to install Dev Patched LGUP:

1) Download and install REGULAR LGUP and then go the LGUP folder on C:\Program Files (x86)\LG Electronics\LGUP and replace the "normal" files with the Dev Patched files (attached to this post).

Install LG Drivers.

REBOOT THE COMPUTER.

2) Alternatively, you can create the folder yourself and just place the Dev Patched LGUP files there.

Copy all file after unrar to C:\Program Files (x86)\LG Electronics\LGUP
Connect device and run LGUP.exe
Done

(IMPORTANT YOU INSTALL DEV PATCHED LGUP IN THE RIGHT PLACE. The dev patched LGUP needs to go where regular LGUP is normally installed, so it will run correctly.)

Install LG Drivers.

REBOOT THE COMPUTER.

However, some people report better success installing "regular" LGUP first.

It's fairly easy. Most people breeze right through this. But if you have any problems, go through this list:
  • Make sure you in download mode BEFORE opening the patched LGUP file.
    This is at the top of the list as some people forget to do that. The remainder are in no particular order. If that doesn't work,
  • Try different USB port,
  • Try different USB cable,
  • Try different computer.
  • Reinstall LG mobile drivers.
  • Reinstall dev patched LGUP again, making sure the files are placed where they need to go (LG Electronics folder, etc).
  • Reboot the computer.

If you ask for help, that's the list of items we are going to give you anyway.

We now have two working download links -- Android File Hosts and Codefire. I'll add the LG Bridge server link when it becomes available. Now I have to actually flash it myself!

DONE. See screenshots.

Thanks for this. So what all do we need to do in order to root again after upgrading? I assume this wipes everything, correct? So do we need to re-flash the new TWRP after we upgrade, then format data and flash the no verity script again, then install magisk? Or is the format data and flash no verity not needed if we've already done that on Nougat? I'm pretty new to using KDZs.

changing this answer based on people's experiences.

Yes, you will lose root and custom TWRP recovery. You'll have flash/reinstall those. Be sure to use the Oreo compatible TWRP 3.2.1:

Yes, I updated my still-bootloader locked US998 V30+ immediately. I'll do my bootloader unlocked, rooted US998 V30 later...

I just relock bootloader before flashing. But now i have warning "your device has failed a routine safety check and will not boot" and does not even get into bootloader mode. Do you have any idea?

See this thread for the V20 but you need KDZ for the V30.

https://forum.xda-developers.com/v20...vices-t3524903

You should still be able to use Oreo KDZ and LGUP, I would think.

EDIT:
After further discussion, I've removed instructions to re-lock the bootloader as people have successfully upgraded without doing that.

I just know if you don't relock the bootloader you have problems then relocking it after flashing the update.

I dont know how but i could enter bootloader finally. I just unlocked again. I guess problem was that i was on custom rom with TWRP. now first, flashing 10d kdz, and then relock and then i will flash oreo.

Deleting this post as information has changed. Do NOT re-lock the bootloader.
