Go to US998 20h (last Oreo, it's the best of the Oreos).

I had no problems going to Pie with a Frankenstein V30+. Just flashed Refurbish mode with Dev Patched LGUP.
But some do have problems. Like you they get stuck on the ThinQ logo.
We have a workaround in post #6 of the US998 Pie KDZ thread -- but it involves bootloader unlock and TWRP. It's a little complicated for anyone who isn't even rooted yet.
I'm suggest flashing to US998 20h (not 20b!) and staying there until another US998 Pie KDZ is released.
How do you downgrade back to Oreo? I can't shut down from the LG screen to get back into download mode.
Holding power and volume down will reboot, but that just gets me back around. I can get into the "factory data reset" screen by lifting the power key on reboot, but that's not getting me any closer, either.

Start with the phone connected to PC via USB. Press both power and vol- until the screen goes blank. As soon as the screen goes blank, press only the vol+ button. That will take you to a download mode.

You may give it a try. BTW, r u sure your battery is charged or not faulty?
Well, i saw that defective phone on ebay with those symptom but nobody reported that type of bootloop, might give it a try and buy it.
My LG v30 is the At&t model. frankensteined to US99820H with twrp 3.2.3.7. I did a factory reset and installed the H93030b pie update. now the phone is stuck at LG V30 screen. stays there for about 5 minutes then reboots and repeats. my computer is not recognizing the phone while on the LG v30 screen or even in download mode. I tried factory reset and it freezes then reboots again. it appears when it goes into download mode it freezes then reboots also. I'm trying to reflash an old kdz but the phone is not connecting to the computer. LG UP says no handset connected. please help, if we know of a thread or a way to help please share. thank you.
My V30 got an Update yesterday. It downloaded and I pressed install, hooked it up to the Charger and left it there to do its thing... After about 80% was completed it automatically restarted and now it stops booting at the LG screen. I tried pressing the POWER OFF switch but nothing happened (even after a full minute). Then I tried POWER OFF + VOL. DOWN. It rebooted, showed me some error and got stuck at the LG loading screen... Did POWER OFF + VOL. DOWN again and tried to enter Recovery mode with pressing POWER OFF again... Stuck on LG loading screen...
What di I do?
I have exactly the same problem.
The error showing is:
Your device has failed a routine safety check and may not work properly.
I contacted both LG and my carrier about it, both said that I should send it for repair, but that will cost me a lot of money.
I tried a hard reset, but it didn't seem to work.
I'm wondering if more people seem to have this problem after the Pie update, but more importantly, does anyone know how to fix this?

Unlocked bootloader message is normal. If it's stuck there then try factory reset erasing all data
I had exactly the same problem with 30b software. I was coming from 21w with all my data on there (22j never came with OTA). I hooked up the phone onto PC and ran LG Bridge where it showed that I have update waiting (nothing showed in phone settings Update option). So I vent ahead, LG Bridge downloaded 3GB update, phone restarted, update began to load. After finishing phone restarted again and was supposed to boot into updated Android 9 but got stuck on LG logo instead. Tried all button combinations but no luck. Then decided to downgrade to 21w again as that one was working before. Unfortunately for me, I left option on to refurbish the phone (all data gone). Silly me. So then I flashed 22j and left it boot. As I logged in on the phone the message popped up about new update. Software version 30b (Android 9). I left it to download (1.73GB) and updated it. Booted without problems. Just to clarify, I had non rooted stock 21w, which came after I let the LG Bridge to repair my phone as no updates were coming. It did that and immediately received 21w software. Since then I had no updates or notifications.
I have the same problem, my device is a korean V300L, boot correctly on oreo V300L21S, but doesn't boot on update V300L30D, stuck on LG logo, then I've back to oreo by refurbish with lgup.
I had the same issue, this video helped.

Took me a few tried to get it but once I did I was able to erase everything then boot. Hope it helps.
Ok, I was following a guide on how to cross flash the LG G8x .kdz file to get Android 11. (the G8x AT&T variant refused to update).
I followed all of the instruction, but while using LGUP, I got a weird error code that I could not find information on anywhere. Now my phone is in a fastboot bootloop, and the bootloader is listed as locked.
Is there any way to get into EDL mode? I have a number of files I could restore using QFIL, but cant get into it from the bootloop.
Are test points an option? if so, which are the test points I need to use?
Any help or advice is welcome, I'm able to take the back glass off if I really need to although I would really prefer not to.
Thanks in Advance!
Hey, I have a G8x , I faced the same problem, all I did to fix it was to boot into edl mode by hitting start on fastboot and pressing the edl button combination with your phone being connected to PC i.e hold down power & volume down and keep pressing the volume up as soon as the screen turns black
