US998 original, TWRP 3.2.3-7-DataImg, bootloader unlocked
Have tried installing both Lineage and LiquidRemix, with no success. Upon reboot, phone bootloops. Easily put it in download mode and start all over again, using factory image (data seems to be getting corrupted).
When in recovery: factory reset, then wipe data, dalvik, cache, and system. Only installing ROM at this time, trying to weed out potential problems.
Tried flashing just no-verity earlier and phone was stuck on splash screen, then.
Any suggestions on this would be appreciated. Not sure where to pull a logcat, even if available, as I am not 100% sure where the problem is originating from.

Did you ever update stock firmware to newest update before trying to flash a custom ROM?

Was rooted, with Magisk, on US99820H, when i did it the 1st time.
Thought there was a chance maybe i had not removed encryption but it seems to be something causing data corruption.

I've no idea if this will or won't help, but have an ls998 converted to us998 which has successfully booted numerous of the custom roms, even from us99820H.
I always remove any accounts on phone, any finger prints unlock, pins, everything. Then do a factory reset. It should be bone stock at that point (for 20H), except of course bl unlocked and twrp installed.
Then, install the rom as you have been. If it doesn't boot, in the various after market rom threads people have discussed fixes they've found. But from what I've read it seems a pretty common problem is the device itself. You say it was an original us998? Was that US Cellular us998? I had one of those, it wouldn't boot an aftermarket rom either.
good luck, Cheers
Did you try flashing the TWRP ready firmware for your phone?
This is what ChazzMatt said: "If you are installing/updating latest US998 firmware for the first time after bootloader unlock/root, you should flash 20e zip (below), then 20f zip, 20g zip, 20h zip back-to-back in TWRP, then flash Magisk. If you go straight to 20h via TWRP-flashable zip from very early Oreo, you will most likely have problems. There were massive changes starting with US998 20f and you need the prior 20e as foundation before going on to 20h. You should also do this if coming from a custom ROM."
So, I am guessing you can flash a custom ROM by just flashing 20e first then the custom ROM after. Instead of flashing a custom ROM from 20h, which is known to cause issues.

Thought US998U was US Cellular but went on to their website to verify IMEI...device not compatible with their network.

IF it's been converted from LS998 you'll get a false result like that. You're sure you have original US998?
US998U just means US998 V30+. U.S. CELLULAR sold them as well as B&H Photo, Best Buy, Amazon...
I know nothing about U.S. Cellular. It's possible they only allow phones they sold, whose IMEI are on their database. I don't know.

TWRP: TWRP-3.2.3-7-default.img
Haha - had just noticed this comment before coming on here to respond! Yes, I went from B to H, without the tweeners. Honestly thought I had read everything...
Did not see the note where flashing from 20H causes problems. Do you have a link for that?
Will go back and install E and F, at minimum, as he said massive changes happened with 20F. Really want this phone to work with AOSP rom's, especially since I paid around $250 for it, but willing to still use it stock and rooted. Phone before this was a Nexus 6, which I hung on to for as long as I could (over 3 years...) but after this, going to OnePlus or Pixel.
Thanks for your help!

Did LG developers website give u the unlock bin for this device? That would be the definitive indication of what device it is as there is only that one and the 930 you can get unlock codes for.
*If* that's the case, that LG identifies it for unlock purposes, then I can only say be sure to have done what's mentioned above in removing accounts etc. After doing that, and an aftermarket rom won't boot? I'd be at a loss. It really wouldn't make any sense at all.

LG NEVER gave bootloader unlock code for any US998U aka US998 V30+ (128GB). I have Open Market US998U (V30+) bought from B&H Photo and had to use WTF bootloader unlock.
Only my US998 V30 (64GB) bought from B&H Photo was eligible for LG bootloader unlock code, and even then you have to hack the LG Developer drop down menu to get a code. No US998 is listed on the LG Developer website.. LG never officially put the US998 on the approved list. Yes, for original B&H Photo 64GB US998, you can still get LG bootloader unlock code -- but you have to know how to do it. However, we have no need with WTF exploit.

Bought new SD card today and doing as ChazzMatt originally suggested, which is start at B, then do E and up. Stopping at G, and trying from there.
Thank you...but no thanks to the drama.
I appreciate the help but sadly, skittles-1999 offered the best response, which I must have overlooked when reading everything I did.
Phone was bought off of Swappa and assured by seller it was a US998U. Box stated as such, model number shows as LG-US998. KDZ downloaded/installed, from LG, was a US998. Cannot think of any other way to verify that it truly is a US998, original.
Things I have changed - new microSD card, 1, and 2, have gone from B, to E, F, to G.
Have to step out but will try installing lineage later.
Tried installing Lineage, Magisk, and Gapps all together. Will try to go back and reinstall just Lineage, to see if that fixes the problem.
Thanks for everything.
Erm calm down?
Thread cleaned. No flaming please. Read Rules.

Have tried flashing this:

Running US99820H, Magisk 19.3 with root. Even tried installing Lineage 15.0 (8.1) but again with no success.
System wipe
Advanced wipe: Data, Internal Storage, System, Cache, and Dalvik Cache
Format data
Reboot recovery
Install ROM
Install DM-verity
Install Magisk

Can flash 20H zip, along with any other Magisk module, with no problem. Guessing it has something to do with boot.img?

Have downgraded to US998E. Is there a possibility partitions on the US998U have the same problem as others, such as the H931/H933? Would I brick my phone if I partitioned, using an H933 rom?
Tried installing bootlegger, with permissive kernel, but bootlooping as we speak. Have been at this, off and on, for days, with no success installing an AOSP rom but will try the suggestion offered. At the point I am ready to keep this as a backup and buy either an H930 or a US998, no plus.

No, plenty of US998U (V30+) are running AOSP/Lineage custom ROMs. US998, US998U, US998R are all identical internally -- except for storage amount or RAM.
If you wish to try H933 workaround, no you won't brick the phone.
Ok using Lgup put my foot in it with complete wipe and flashing a kdz and now lost the imei number and whatnot can someone help.......please
You didn't lose your IMEI just by flashing a KDZ using the recommended Upgrade, Partition DL or Refurbish methods. You must have flashed using some mode NOT recommended in any of the Instructions. We specifically say to NOT mess with any modes not mentioned.
In all my Dev Patched LGUP instructions, I include this:

Why do you claim that?
You simply flash KDZ via Refurbish or Partition DL with Dev Patched LGUP and your phone is updated.
Most times you can even flash KDZ via Upgrade mode and keep data.
In ALL the KDZ threads we have, where users update their phones all the time, we only use Upgrade, Refurbish, or Partition DL modes.
What variant do you have?

The fact the update is out there and tried LG bridge and tried a few other ways to push the update to no success........it is a v30 us998 being used in Australia is probably the reason.
I'm using the device right now so it is only a cosmetic thing at the moment.

Follow the instructions in the US998 KDZ thread. We post all the KDZ images there, with several mirrors for each KDZ release.
You simply download the KDZ, flash via Upgrade mode with the Dev Patched LGUP -- which is also provided in the first post. At the most use Refurbish mode.
There's plenty of Instructions in the KDZ thread and how to use Dev Patched LGUP.
See Post#1.

The Dev Patched LGUP in that US998 KDZ thread works for everyone around the world -- unless the seller did something to that USS98 with Octoplus box which Matt may prevent that Dev Patched LGUP from working right.
I saw that one time before with AS998, where Dev Patched LGUP couldn't do anything because dealer had messed it up with Octopus/Octoplus box when converting it from LS998.

Using dual mode LG UP in OP of US998 kdz thread and directions from post #6 on "how to get past stuck v30 logo", go back to freshly kdz 20h, H933 Nougat to get imei and partitions back, then 20e, then 20h, and lastly pie 30b

All US998 are already carrier unlocked. Even U.S. Cellular.
If you're trying to update to Pie it's a different KDZ thread. I assumed you were trying to update to latest US998 Oreo since to you said it wouldn't update...

Luckily you still have box with IMEI, etc.
You'll have to Google for tools to repair your IMEI. You know what it is, you will just need to type it in.
It's a touchy subject on XDA we can't really discuss in depth because some people for nefarious reason want to CHANGE their IMEI and XDA frowns on that.

What step do I have to follow to recover my V30? can i flash a kdz of us998?

You need to use Dev Patched LGUP and you need to read the Frankenstein instructions.
Unless you're a Verizon customer it's probably better to use US998 firmware.

thank you very much, could you tell me where I find Dev Patched LGUP and the frankestein guide.

hello thanks for the help, you say it is convenient that I use LGUP and flash a KDZ of US998 in my supposed VS996? since I supposedly have a VS996 and LGUP detects me that it is a VS998.
Can the KDZ ROM be exchanged between these two models?
I am from Argentina and I do not use any of these companies, only the 3g and 4g bands that are the same in Argentina.
The next question is if there is any guide here to use LGUP since I did not find or know what words to use in the search engine because of my English translation.
Thank you !

Go to US998 20h (last Oreo, it's the best of the Oreos).
This first US999 PIE is wonky and some people have problems updating to it. 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.
Hello again, I read the guide that happened to me kindly, but there are some points that were not clear to me and I want the advice of the expert experts here.
First when I install the LGUP from the link that happened to me I follow all the steps but I can not enable the developer mode and when I connect the phone I get this legend
Ask me to install a valid DDL, how would this be?

If you are using the LGUP from the Frankenstein instructions, the .dll error means you didn't install it correctly.
I don't see you mentioning the SetDev.bat step?
After Installation, you launch Dev Patched LGUP by using the desktop shortcut, not through an icon in the folder.
Uninstall LGUP from your Programs folder, and reinstall.

Uninstall LGUP from your Programs folder, and reinstall.

Hi @ChazzMatt, I could finally flash it, I tried it on a different computer and with Windos 8, I detect the phone perfectly I could do cross flash, from US998 that detects LGUP to VS996, I perform the flash perfectly at 100.
But it is restarting in the Verizon Logo just as it was not restarting, it is still the same, try the master reset that they cite in the guide post, but I perform the master reset and it remains the same, the truth that I would not know what to do, Can't get into the android system, only the LG V30 logo appears and then the Verizon logo and it is loading, but from that screen does not happen, any other alternative to leave this part?

Your earlier screenshots show you trying to go straight to VS9930 Pie 30c from US998 Nougat 10c. Are you still trying to do that? Frankenstein instructions specifically say you have to flash Nougat first, Master Reset, then you can update to newer firmware.
This means you need to flash VS996 Nougat, Master Reset, then update to newer VS996 firmware.

@ChazzMatt Thank you very much, I took it to a technical service, where they have octopusbox for different services, but they could not do anything, it seems to me that they do not know how to manage the different octopusbox options and only the most classic ones such as unlocks, flash and releases, I will try Again with the instructions you give me, I thank you very much for all the information and the time you take to read, thank you, I will be keeping you updated :bueno:

What I did was flash us998 kdz, install twrp, backup efs, modem, everything. Then did a chip erase in lgup.
Flash oreo Canadian kdz, then us998 kdz, install twrp, restore efs. Then flashed VS996 30c pie rom and like a miracle from Jesus it booted! [emoji106]

Flashing chip erase will wipe out IMEI and serial number.
Your phone was brought back to life by Octoplus or something a few months ago, right? So you have stuff in your phone that's different from most people.
In all the LGUP instructions I tell people to not mess with Chip Erase.

That was my original vs996. I got a second vs996 that I'm using now. If you backup efs, you can restore your imei. My serial is gone, but I don't need it, and now I can boot Verizon Pie.
OK never mind battery died overnight, charging now to go back to us998h.....
Ok converted v30 locked boot, no root us998h to vs996k, all went fine. it upgraded to L then tp pie vs996. Now just sits at verizon screen with colored dots. Did master reset and satill the same. Used partition dl for K and went just fine. How do I get back to phone off to redo vs996k and reject pie upgrade' Thanks

Hi all,
First some details:
LG930DS
secure startup enabled
H930DS30s_00_OPEN_HK_DS_OP_0902.kdz installed via LG Bridge. It changed me from AU to HKG for reasons unknown to me.
rooted with TWRP and Magisk 20.1 installed
I'm having issues with VoLTE not working (actually no longer in settings of the hidden menu) since installing Pie and I want to rule out the HKG variant as the cause. To do this I will install H930DS30c_00_OPEN_AU_DS_OP_0902.kdz instead. I have downloaded this kdz but now I'm not sure if I can install it without having to wipe and re-do all the Magisk and TWRP (and setting up all my files and apps again). After reading the guides none seem to answer this question quite right as they are mostly aimed and either US, EU, or India with their TWRP flashable roms like this one https://forum.xda-developers.com/lg-v30/development/us998-lg-v30-us998-us99830a000704-kdz-t3952256
Can someone with a better idea of how this works let me know the best option for me to switch over to the AU variant.

LG Bridge will look for the KDZ intended for your IMEI, not the firmware you have on the phone right now. Was your phone imported from Hong Kong (China)? Or did you buy from Australian carrier or Australia LG authorized retailer? Did you buy the phone new or used? Have you updated it before using LG Bridge?
Any H930DS can be flashed to run any other H930DS firmware. Best guess is somehow the phone was originally Hong Kong variant and someone flashed it to Australian firmware. When you went to look for update via LG Bridge, then it updated to that region Pie meant for that IMEI.
Unless you have used LG Bridge successfully before and you are sure it is Australian IMEI H930DS?

We haven't always had TWRP-flashable zips. Only thanks to generous, talented devs do we have the collection of TWRP flashable zips for US998, H931, H933, VS996, LS998, T-mobile H932, H930, India H930DS. That's only 8 of at least 20 variants and I'm not even counting all the different regional variants of H930DS...
So you will have to do what we all did before TWRP-flashable zips, and what we will have to do again when some of our TWRP flashable zip devs move onto other phones.
Method #1 -- Works some of the time on Oreo, not yet tried on Pie
This worked for many people in Oreo -- but some still had to reinstall TWRP, reformat data, reinstall the root files. Never could figure out the difference between success and not. Then we got TWRP-flashable zips and the issue became moot.
1) Make backup in TWRP AND make backup of all apps in Titanium Backup.
2) Flash new KDZ via Pie-compatible Dev Patched LGUP in Partition DL mode, but omit the Recovery partitions. Do NOT select "all partitions". This will let you keep TWRP.
3) Boot into TWRP via fastboot commands from your computer, just like when you first installed TWRP using the WTF instructions. (Best not to use the stupid hardware button dance.) Once in TWRP, then choose Reboot to Recovery (from within TWRP) to get the actual internal phone TWRP, instead of the PC TWRP.
4) Flash the Pie-compatible three root files (Magisk, encryption disabler, root check disabler, Magisk again). See attachments on this post to download those files.
5) Restore all Data from within TWRP. Do not choose any other categories.
6) Wipe all Caches.
7) Reboot
Restoring all TWRP data may or may not overcome the fact that you have re-flashed encrypted stock Pie on your phone. IF it does work, then after rebooting the phone if anything is still wonky, use Titanium Backup to restore all apps and data (this is in addition to the TWRP data restore you did).
Good luck.
Method #2 -- Works all the time, but yeah you have set up your phone again
1) Flash new KDZ via Pie-compatible Dev Patched LGUP in REFURBISH mode.
2) Your phone is now on the region KDZ you desire and you still have unlocked bootloader. You will need to reinstall TWRP, and then flash the three root files (Magisk, encryption disabler, root check disabler, Magisk again). This includes the step where you reformat all data with a "YES".
See instructions here:
REINSTALL TWRP on PIE stock KDZ with ALREADY-UNLOCKED BOOTLOADER
THAT POST ASSUMES YOU HAVE PREVIOUSLY UNLOCKED BOOTLOADER, AND THAT YOU HAVE NOW UPGRADED TO STOCK PIE KDZ. YOU HAVE UNLOCKED BOOTLOADER and are STILL on firmware which has FASTBOOT FLASH COMMANDS.
___________
Dev Patched LGUP
Dev Patched LGUP vs regular LGUP is necessary when cross flashing across regions or other variants. You will need this for either of the two methods above.
Here's how to flash with LGUP:
UPGRADING LG V30/V30+/V30S TO PIE KDZ FIRMWARE WITH LGUP
1) Go into download mode (power off completely, then hold volume up button while plugging in USB cable)
2) open Dev Patched LGUP and flash PIE KDZ either via PARTITION DL MODE (but omit Recovery Partitions for your purpose in this thread) for Method #1 or via REFURBISH for Method #2.
Use the attached patched LGUP in this post. If you get a ".dll error" you either didn't install correctly or are using the wrong version of Dev Patched LGUP. Read the installation instructions carefully. Some people have used OTHER versions of LGUP before and ignore the installation instructions -- they think they know how to install and they do NOT --- then complain about .dll error, which is their fault.
* NOTE: YOU CAN NOT USE LGUP "UPGRADE" MODE IF YOU HAVE TWRP CUSTOM RECOVERY. LGUP "Upgrade" is like a manual OTA and is only for pure stock (but you can have unlocked bootloader).
3) IF your bootloader is unlocked, it will remain unlocked after flashing KDZ.
_________________
HOW TO INSTALL DEV PATCHED LGUP
0. UNINSTALL any prior LGUP version. Seriously. Go to Programs folder and delete the LGUP folder if you must.
1. DOWNLOAD THIS DUAL VERSION OF DEV PATCHED LGUP, made by @tecknight:

It's all 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 on your PC.
Reinstall dev patched LGUP again.
Reboot the computer.
If you ask for help, that's the list of items we are going to give you anyway.

Ahh thank you for explaining this. I imported mine from Hong Kong. As far as I know it was never sold new in AU.
I'm about to rush off to work for the day so I will have to try this when I get home tonight and let you know how it goes. Thank you so much for the detailed and fast response! This is much more than I was hoping for!
One last question. Do I need to disable secure startup or does the encryption work with the method #1?

I don't know the Australian market, but we have an Australian XDA moderator who has or had Australia H930DS. Since there is Australia H930DS firmware, I assume it was sold new back in 2017/2018 by some carrier or by LG authorized retailer.
He has Vodafone in his profile. @Redline.

This is correct. I bought one BNIB from an eBay seller, a H930DS and it was only a couple weeks old from the factory. Came pre-loaded with AU firmware and I updated it to the latest. Before going the LineageOS route.

Interesting to know. I bought mine back in 2017 but I couldn't find it in AU and read somewhere that imports were going to be the only option. To bad for me.
I know little of what IMEI's do. Is there any issues related to regional OS versions and the IMEI of a device? Is the hardware otherwise the same?

I could kind of answer is the question of if the hardware is otherwise the same, the rest might be a question for ChazzMatt.
AFAIK the modem on my H930DS was the same as other similar models, similar to the V20 you can flash a KDZ from another region if you wanted to (to for example, get less bloat or better coverage on a band you rely on for service). I remember on my V20 the region that had Claro-carrier firmware came with the least bloat out of the box vs other regions, but we also had KDZ Writer with the V20 that allowed us to flash specific parts of the KDZ *in* TWRP on the device itself, so you could have, say, Claro firmware with the AU modem.
As for what IMEIs do, they're similar to the MAC address on a piece of networking gear; it's a globally-unique identifier specific to your device, you can put it into IMEI lookup websites to get information about manufacture date, model etc.
If you have a carrier-model phone, they can also block your IMEI on their network if it is stolen and then attempted to be re-used.
I've had to opt with #2 as the encryption was a problem as you suspected. I'm puzzled though... while I was setting up for USB debugging I noticed that I had VoLTE in the drop down menu, however, calls still reverted back to 3G. I didn't pay much attention to it as I had to do a format in the steps to follow. Now that I'm back up and running I no longer have VoLTE in the drop down menu? It's the only icon missing. Calls still revert to 3G again. I'm on the boost network which uses Telstra and this phone is listed as compatible for VoLTE with them. I know that it worked in Oreo too.

Hmmm.... Sorry, I don't know. But you are back on Australian firmware.
If you wish, you can use the same procedure to downgrade back to Australian Oreo to see if you can get VoLTE back.

Out of frustration I started doing random things just to test there effect, much of it being in the hidden menu where I discovered VoLTE settings. Nothing was working until... I force stopped the carrier service and made a phone call. Presto! VoLTE now appears (though not listed under any setting in mobile networks, or in the drop down menu) and my calls say HD call. Finally to confirm 4G remains active and still works during a call!
I tried to root my phone but I failed among the many steps. I just flashed US998 ROM on my V300L because I ****ed up and flashed the wrong ROM instead of the stock ROM. And I didn't unlock my bootloader so I can't install TWRP. I tried to revert back to V300L ROM with LGUP but it's not connecting to my computer(I tried using another computer and a different cable.). And on download mode screen it says:
Unknown B78
Official / E / L / RO
It seems that the version I wrongly flashed was an Oreo Rom.
Update: Since then the device boots up to setup page but after a while it just reboots. It connects to my computer while in this state.
Please, help me get my phone back.

These were the directions you were following?
https://forum.xda-developers.com/showpost.php?p=76989743&postcount=7
Both H930 and US998 KDZ you were to flash are early Oreo KDZ. It's just you were supposed to flash the H930 first, unlock bootloader, then flash US998 to get modem working again. Also after bootloader is unlocked, V30 "trust chain" or whatever it's called is more permissive -- which is probably why you can't flash US998 first to unlock bootloader, but can after bootloader unlock on H930.
I notice those instructions (if that's what you were using) reference older versions of TWRP, root check disabler and encryption disabler. You need newer versions of those files, especially TWRP. You need 3.2.3.7. Newer versions of those files are found in the WTF Instructions. If you read that post, read in a web browser, not an app.
For your immediate problem, the only things I can suggest to you is to:
0) Try Master Reset to perhaps stop the bootlooping? May or may not work in this instance. But it's what we use after cross flashing North American variants. However, even then, we often have to go back to Nougat first.
With your device powered off, press and hold the Power button and Volume Down buttons simultaneously for a few seconds.
When the LG logo appears, quickly release and then re-hold the Power button while keep holding the Volume Down button.
Let go of the buttons when the onscreen menu appears.
When you see the option to Delete all user data (including LG and carrier apps) and reset all settings message prompt, press the Volume Down button to highlight Yes.
Then press the Power button to reset the device.
Wait until the reset is complete then reboot your device. If it’s able to boot up successfully, proceed with the initial setup.

1) manually go into Download mode before starting LGUP (power off completely, then hold volume up button while plugging in USB cable)
2) try both the newer Pie Dev Patched LGUP as well as the older "Oreo" Dev Patched LGUP. Pie LGUP does work on even Oreo and Nougat but there are certain situations -- and this may be one of them -- where the older Dev Patched LGUP is needed. Read the installation instructions carefully for both versions (they are different!) and uninstall any prior version each time you install another. Besides uninstalling, you may need to actually delete the LG Electronics/LGUP subfolder in the Windows Programs folder.

Again, IGNORE EVERYTHING else about that post except for the Dev Patched LGUP file and the installation instructions.
3) If you can't revert back to V300L, also try flashing to the Oreo H930 KDZ so you can finish the bootloader unlock.
Good luck. I don't have any other answers.

I did master reset. After doing that I got the phone to boot but after 3 or 4 seconds it would just reboot. It's just an endless cycle.
I booted into Download mode before connecting to LGUP. My computer doesn't connect to my device when in Download mode. I tried using different cables and computers none of them worked. Same results on everything.

And you've tried BOTH versions of LGUP that I recommended? And you uninstalled and totally removed any prior versions before installing each TOTALLY DIFFERENT version?
Be sure to read the installation instructions carefully. They are totally different.

ChazzMatt, I have tried removing and installing both versions of the patched lgup and I'm at a loss. The DualMode zip doesn't read my phone and I notice it doesn't have the common folder when I run the dev batch file. The Oreo patched lgup goes into the set but it states the Dll =0. I am running a vs996 and trying to downgrade to 10d. I am at a 30c right now. Could you tell me a step by step of what you do to get the Dual mode zip patched lg up to work? The process I am filling is remove old, restart, install lg up, run admin on dev batch file, then restart and hook up in dl mode. Always tells me that it can't find my model.

Combining several posts in different threads and from PM into one question
These were the directions you were following?
https://forum.xda-developers.com/showpost.php?p=76989743&postcount=7
Both H930 and US998 KDZ you were to flash are early Oreo KDZ. It's just you were supposed to flash the H930 first, unlock bootloader, then flash US998 to get modem working again. Also after bootloader is unlocked, V30 "trust chain" or whatever it's called is more permissive -- which is probably why you can't flash US998 first to unlock bootloader, but can after bootloader unlock on H930.
I notice those instructions (if that's what you were using) reference older versions of TWRP, root check disabler and encryption disabler. You need newer versions of those files, especially TWRP. You need 3.2.3.7. Newer versions of those files are found in the WTF Instructions. If you read that post, read in a web browser, not an app.
For your immediate problem, the only things I can suggest to you is to:
0) Try Master Reset to perhaps stop the bootlooping? May or may not work in this instance. But it's what we use after cross flashing North American variants. However, even then, we often have to go back to Nougat first.
1) manually go into Download mode before starting LGUP (power off completely, then hold volume up button while plugging in USB cable)
2) try both the newer Pie Dev Patched LGUP as well as the older "Oreo" Dev Patched LGUP. Pie LGUP does work on even Oreo and Nougat but there are certain situations -- and this may be one of them -- where the older Dev Patched LGUP is needed. Read the installation instructions carefully for both versions (they are different!) and uninstall any prior version each time you install another. Besides uninstalling, you may need to actually delete the LG Electronics/LGUP subfolder in the Windows Programs folder.
Find the Pie Dev Patched LGUP here:
https://forum.xda-developers.com/showpost.php?p=79971595&postcount=3
IGNORE EVERYTHING else about that post except for the Dev Patched LGUP file and the installation instructions.
Find the Oreo Dev Patched LGUP here, bottom of post #1:
https://forum.xda-developers.com/lg-v30/development/us998-lg-v30-us998-us99820a040330-kdz-t3786337
Again, IGNORE EVERYTHING else about that post except for the Dev Patched LGUP file and the installation instructions.
3) If you can't revert back to V300L, also try flashing to the Oreo H930 KDZ so you can finish the bootloader unlock.
Good luck. I don't have any other answers.

Same boat. Flashed Pie over Oreo via zip, lost twrp, and download mode doesnt connect now...
I have problem with lg v30.
It is v30 VS996 (maybe). but it was flashed US998 Pie. And now it has an error on camera and fingerprint.
I can not enter download mode to flash stock rom and bootloader is locked.
Please, tell me what should i do.
Thank you very much.
See my response in the other thread where you posted.
And please don't cross post. It is very disrespectful of other members who are trying to help you. That's why it's against the rules on every forum on the internet.
