Hi everyone,
A couple months ago I switched over to T-Mobile. I bought my V30 from AT&T and got it unlocked after switching to T-Mobile.
Apparently Android Oreo 8.0 is rolling out to AT&T V30s but when I check for updates no updates are available. Is there any way I can get my phone to update now that I'm on T-Mobile?
Thanks

If you can get your hands on an active att sim card, or from one of its MVNOs. That is how I updated my lg gpad. I put an h2o sim card and the next day the nougat update was already loaded. Other than that all I can think of is flashing the firmware.

I had an AT&T sim in my LG-H931 (that is unlocked and has been running on T-Mo since I got it) for about an hour on Saturday with no luck. For what it is worth, I am still on the September security patch, so at the very least I would have expected to see an update to that right away.
I may be unhappily stuck on 7.1.2 unless someone else figures out a trick.

Any luck?
I'm in the same boat, a firmware file that we could flash though bridge would probably fix it, but I haven't found any firmware files for the H931 Oreo anywhere =/
Update?
Any update with this? I am on the same boat. I bought unlocked V30 from attached and use it with MetroPCS..
I bought ATT prepaid card hoping that it will prompt the update with no luck so far.
Considering flashing but like previous poster said , I could not find update file for H931 ATT oreo.
Switching from Apple btw and I wish I did it a long time ago, love it!

There's long been an "update" with this. You convert the H931 to open market US998 and flash the latest KDZ. See the Frankenstein thread. I post latest US998 KDZ whenever they are released.
https://forum.xda-developers.com/lg-v30/how-to/using-lgup-crossflashing-t3780969
AT&T, along with Sprint, won't release KDZ and won't give updates to non-customers. So, best to convert phone to variant that receives public KDZ.

Sorry Chaz, I hope it is okay for me to post it here. I noticed your name on most LG V30 posts and I know you are probably the best person to ask. First of all I wanted to thank you for providing the instruction for the flashing. I really thought I bricked my phone for a couple times. Here is what I did:
1. Wrongfully ran the flashing not in donwload mode - was not able to turn on the phone.
2. Panicked, followed instruction to master reset.
3. I went back to download mode, Flash US998 Nougat.
4. For some reason it could not go pass the setup (keep restarting).
5. Went to Download Mode - Flash Upgrade to Oreo US988. Stable.
6. I think I was successful as I was able to restore my data and the phone works.
One question..probably a stupid one as I am new android user, but I noticed the User Interface is really different , I believe this is what they referred as a "stock" Oreo? It is useable but the UI is really basic. See the attached link:
[url]https://photos.app.goo.gl/h3eeBdoGTtHRM6Y4A[/URL]
[url]https://photos.app.goo.gl/S1PiJQR3XcYn9cZe7[/URL]
Does this mean I just had my Bootloader unlocked and the phone is now ready to flash different variants with LG UP "update" selection?
I am currently using Metro PCS and was wondering of I can flash Tmobile variant to my phone, not sure if flashing Verizon (CDMA) will cause problem for the network.
Greatly appreciate all suggestions or advice

You're welcome! You've now successfully Frankensteined your phone to open market US998. Let me try to answer your questions...
As you admitted in step 1, you didn't follow the instructions. But also in step 4 you didn't... Luckily you survived it! Especially in step 4 -- between US998 Nougat and US998 Oreo -- is when you really needed to Master Reset, as that Nougat flash is necessary but very unstable. After Master Reset, then that Nougat is stable and you can continue to flash Oreo.
No, your bootloader is not unlocked, but you are carrier unlocked/SIM card unlocked to use this phone on different carriers.
I'm not sure if you are confusing terminology and are really asking about bootloader unlock? (which is necessary for root) You flashed US998 Oreo 20D, which has the bootloader lock security patch. If you want to unlock bootloader, you would need to temporarily downgrade to Oreo 20A or 20B first and run the instructions in the WTF thread... You could root, then update back to newest firmware after bootloader unlock. I'm only mentioning this because you asked about bootloader unlock.
Right now, you now have the open market, carrier unlocked US998 variant -- the one designed to run on all North American carriers. It will run on T-Mobile/MetroPCS quite fine. Lots of T-Mobile users have US998 on T-Mobile. Not only is there no need to flash T-Mobile variant KDZ, but since T-Mobile KDZ has different RSA encryption than all the other North America V30 variants, you'll definitely brick your phone if you try.
You can use "update" for US998 for future updates or you can use simple "upgrade" with full KDZ in the dev patched LGUP when future US998 KDZ are released. Simple "upgrade" in dev patched LGUP does not wipe your data. You had to wipe your data THIS time because you were converting to another model. Now that you are on US998, you can stay there. In the future you can just use "upgrade" for KDZ if you do not receive update prompts. I prefer flashing full image KDZ myself instead of partial image OTA.
The plain look is just the layout and theme choices you've made. (Go into Settings and search for Home and also Theme. ) Plus there's no carrier bloatware on US998. Also Oreo looks a little different, if you're just upgrading from Nougat.
For myself, I use Nova launcher with an icon theme pack to change the look. It has lots of different choices. I prefer a separate app drawer, and I prefer my app drawer have a black background to clearly differentiate it from my desktop. I like the Nova "cube" transition to go to my different desktop screens.

Appreciate the answers, Chazz.
Ok, I believed I did not do master reset from H931 to US998 Nougat but I did master reset from US998 Nougat to US998 Oreo. Now that you mentioned it, that was probably the reason why I succeeded.
Yes I am pretty sure I mixed up terms as I am probably not 100% with the terminologies, my apologies. Thanks for the warning, will definitely not flash T-Mobile variant.
Good to know that from now on I just have to do upgrade through dev patched LG UP to update US998 kdz.
I think the reason I thought the step was not complete was because in the UI, I was not able to move any app shorcut (and widget) on my screen. It is also not arrangeable. Also when I go to App and touch-hold the app icon, there is no option delete it. Is this normal? I went to try different themes and it did not fix the problem. I youtubed LGV30 Oreo and it looks really different from my current phone.
Couple of screenshots:

Try Nova launcher.
If that doesn't fix the problem, do a Master Reset and then use dev patched LGUP and DL PARTITION (choose all partitions) the US998 Oreo KDZ over your phone. You may want to do that anyways...

Chazz,
I'm not sure what the difference is or what my options are at this point.
I picked up a LG V30+, which I thought was a US998 or at least that's what it says on my phone (Hardware Info). But when I ran the iemi # it comes back as an LS998.
Honestly don't know what the difference is and wouldn't care except for the fact that I can't send SMS text msgs. Seems like everything works even receiving SMS msg's just can't send. Oh and it turns out I can't see/view the SMSC #, which I guess is a big deal in regards to sending SMS msg's.
So I've been browsing through this site and you seem to be well versed and would like your opinion/advise if I may.
Q1) Will updating the firmware help?
> Says I'm @ Rev 1.0
Q2) Will updating the software help?
> says I'm at US99810d and Android Ver 7.1.2
Any suggestions/thoughts would be greatly appreciated.
Thanks,
Dirty D.

GENERAL INFO
Yeah, most new and "mint" (like new) US998 V30+ on the market right now (eBay, even Wal-mart) are former LS998 which have been converted to US998 by 3rd party wholesalers trying to offload excess LS998 V30+ stock. Basically like our Frankenstein but probably done though Octopus box or some mass version of that.

"lightbox_toggle_sidebar": "Toggle sidebar"
}
I've noticed they often will convert to US998 but leave on Nougat for some reason. Maybe their Octopus box can't do Oreo for some reason? To me, that's a half-finished conversion! When I do it, I go all the way to Oreo!
Sometimes they will actually claim "US998" in the listing -- while other times they will say "unlocked V30+" but then list the US998 bands (which are different from the Sprint LS998 bands), so you assume it's a US998. Neither is technically incorrect, nor lying. It IS now a US998, and it does now have US998 bands... The BEST way I have seen is where they claim "UNLOCKED LS998" -- and when you get it, it's of course converted to US998, as that's the only way to unlock an LS998.
Caveats with former LS998 converted to US998:
If you use Verizon you would run into issues ACTIVATING a new SIM card with a former Sprint phone. You would need an already-activated Verizon SIM card. That's the only quibble I have with the converted LS998, where the origin is not fully disclosed. It doesn't bother me as I use Prepaid AT&T, but I have to warn others.
Sprint customers can't use it on Sprint, as it's no longer really an LS998. Sprint won't allow US998 (even former LS998) on their network. But advertising an "unlocked" LS998 might be attractive to a Sprint user who is thinking of switching to another carrier in the future or to buy a phone that can easily be re-sold. They should be told upfront it's a FORMER Sprint LS998.
None of the sellers are lying; it's just a hard situation to describe if you're not familiar with the V30.
Recently in December, I wanted a new (original) US998 V30+ with warranty as a backup, as I had given away all my converted LS998 V30+ > US998 V30+. My wife and I have original US998 V30/V30+, but I alway like having a new backup in a box in case of emergency. So, I specifically bought NEW US998 V30+ from online Wal-mart. Or thought I did! When I picked it up at local Wal-mart I found it's new V30+ all right -- but converted from LS998.... I kept it anyway, as I know it will work fine. But this time I was specifically wanting an "original" US998, even though I had bought converted ones before and had converted two myself.
Anyway, the point to all this is yes, you have a former LS998 converted to US998. So, do several of my friends and my wife used one for awhile. They all work fine on AT&T network. Cricket runs on AT&T network, as it's an AT&T-owned MNVO.

SOLUTION #1
What is possibly the issue is your Cricket APN. Go to your mobile settings and check your APN against this:
https://apn-settings.com/us/cricket-wireless-apn-settings/
You are still on Nougat, so you should be able to edit your APN settings. On Oreo that capability is locked out, but there are workarounds on Oreo and with root you can still edit APN on Oreo, I believe.
SOLUTION #2
Another option you can try is Master Reset. Sort of like a factory reset but more powerful.
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.
SOLUTION #3
As far as the SMSC #, not sure why you can't view it, but the US998 (which you have now) has Hidden Menu which lets you delve deep into various settings. BE VERY CAREFUL in the Hidden Menu. You can mess up stuff, especially if you try to enable additional LTE bands. Don't do that. In the US998 that option doesn't really enable additional LTE bands, but instead locks you on ONE band (which may or may not work).
I've never had to view SMSC #. I stick in my SIM card and the phone works -- even former LS998 converted to US998. So, I'm not sure that's your issue. More likely the APN settings?
SOLUTION #4
Next, you are on very old version of Android. Nougat. At some point, you do need to update to Oreo as it brings lots of fixes and more features.
This thread below is where the stock KDZ are posted. You can use LGUP to update to newer firmware.
https://forum.xda-developers.com/lg-v30/development/us998-lg-v30-us998-us99820a040330-kdz-t3786337
The other reason I am mentioning this is because instead of "upgrade", you can use an option called "refurbish". Refurbish re-builds EVERYTHING while also updating the firmware. It's possible whoever converted your LS998 to US998 botched something, which is why your SMS doesn't work. Using this refurbish option will lay the foundation again, totally rebuilding your firmware.
After you use that "refurbish" option, then in the future just choose "upgrade".

Good luck!

Okay so heres what/where im at.
1) I was able to view and edit the smsc # when the sim was in my old LG device. So i did so and then moved it to my new LG (V30+)
2) Checked & edited the APN
3) Changed the network node from Global to LTE/GSM/UMTS
4) Downloaded LGUP & upgraded
5) Nothing changed on the hardware side - still @ Rev 1.0 but on the software side i'm now at US99820b and Andriod Ver 8.0.0. Its to late to test tonight but tomorrow i'll attempt to send SMS & MMS messages.

Good on APN and the LTE/GSM/UMTS choice.
You only updated to US998 20B (for now) because you intend to unlock the bootloader and root?

Well to be perfectly honest, im already out of my comfort zone. Didnt want to make/take to many changes/chances... Not having any experience in this realm to begin with. It was a leap of faith to begin with.

So I'm not sure of the need or benefit of upgrading from US998 20B to whatever the latest is (appears to be 20G), but should I get the courage to do so, what would the process be?
Would it be as simple as plugging in the phone to the computer and then launch LGUP, selecting upgrade and the 20g kdz? If so I'd be more inclined to do so if their are substantial benefits for doing so.

Yes, it's almost that easy. However, since there's such a large range of changes (especially to audio framework) form 20B to 20G, best to do it in stages. "upgrade" to 20E, reboot, let it settle a few minutes. "Upgrade" to 20F, reboot, let it settle, same with 20G, done.
I wasn't sure exactly what LGUP method you used to get to 20B from Nougat -- whether "upgrade", DL Partition or "refurbish". If the latter two you could have gone straight from Nougat to 20G. But now that you are on 20B, and you want to use "upgrade" (to keep your settings and data), do in those stages.
Since 20B, camera is improved, front and rear. DTS audio framework is introduced. While you still need root to fully enable it, hopefully that will be fixed by LG in upcoming update. Other fixes. Here's the changelog for US998 20F alone.
change log:
- DTS: X 3D stereo effect function has been added.
- New Always On Display options
- Selfie camera portrait mode
- Improved accessibility.
- Improved keyboard performance
- Improved the delay of keyboard input when installing multiple market apps at once.
- Photo display error in some apps since Google's latest security patch has been improved.
- Improved to keep app aspect ratio settings after app updates.
- Improved the phenomenon that fine lines are displayed on some screens when power saving mode is executed.
- Google Security Update has enhanced your phone's security.
Most of the list is found here in the link below -- plus the AOD and selfie camera portrait feature are from public reports. The AOD I verified myself, but the selfie thing seems to be subtle.
But there were other changes between 20B and 20F, and maybe more changes with 20G.

The person below also bought a US998 V30+ and found it's former LS998 V30+ converted to US998, but is still on older US998 Nougat firmware. The dealer/wholesaler probably did via Octopus box or something similar, while we use Frankenstein conversion via Dev Patched LGUP. But we always "finish" the process by then updating to Oreo. So, it's basically an "unfinished" Frankenstein conversion.
They don't have the SMS issue the first person had in this thread, but it's still same underlying issue. LS998 V30+, now on Nougat US998 and they want to update to current Oreo firmware...
Hi ChazzMatt,
I have a question. I am hoping you are willing to help me.
I have an LG V30+ unlocked mobile phone. It says US998 but I just found out that it is actually LS998 (I typed in the IMEI into this website to check what it truly was and it came back as LS998).
The vendor that sold it to me changed the firmware to US998 and I guess removed all the Sprint bloatware or whatever from the phone.
All is totally fine – the phone works great – no issues – I love it and for the low price I got it for it is fine…Except, because of the above, I do not receive any OTA updates.
See attached screenshots of my phone, it is out of date in terms of software and OS and from what I learned from online posts I will never receive any OTA updates.
Is this a problem? Should I update it manually? Can I?
Thank you for your help in advance.

Yes, most US998 V30+ nowadays being sold are already-converted LS998 V30+. You can update to most recent US998 Oreo KDZ via our Dev Patched LGUP.
Later tonight I'll answer more fully.

Yes, the only way to carrier unlock a Sprint LS998 V30+ is to convert it to a North American V30/V30+ carrier unlocked version, using a process which we call Frankenstein. The US998 is the most popular firmware to convert LS998 to, as besides being carrier unlocked is also the only North American V30-series variant with fastboot flash commands (which are necessary if you ever want to unlock bootloader, install TWRP custom recovery and root). The remainder of this answer is on the assumption you do NOT wish to root at this time, but merely wish to update to most current US998 V30/V30+/V30S firmware.
SOLUTION
You can go to the US998 KDZ thread and use Dev Patched LGUP to update to US998 20G KDZ (most current US998 firmware at the moment). Dev Patch LGUP is attached to post #1 of that thread, and there are instructions on how to install LGUP, with screenshots on how to use it.
However, in this instance I would recommend using Dev Patched LGUP in "Refurbish" or "Partition DL" (choosing all partitions) mode -- which while it will wipe out your data, will probably present the least problems. There are a lot of audio framework changes with most recent US998 firmware (especially with 20F and 20G) and if you use "Update" mode (instead of "Refurbish" or "Partition DL") you would have to update in stages to 20E, then 20F, then 20G. Best to do it in one step, with "Refurbish" or "Partition DL".
In the future, with other KDZ you would merely use "Update" mode, which WILL keep all your data. It's like receiving OTA updates, but you would be flashing it manually.
MORE INFORMATION
Just for more information (if you are interested) you can also read this Frankenstein Instructions post, on how to convert from LS998 to US998 Oreo -- but several steps have already been done for you. You are already on US998 Nougat. The only step left is to update to US998 Oreo. In that post, you would be on Step #4. Ignore that it says to use "Update" mode. In this instance, I think you should use Refurbish or Partition DL mode. You can use "Update" in the future.
Hope this helps.
Thanks for the great advises Chazz. I was looking for a phone for my dad and your posts made me decided to get the LG V30 for him. I'm still waiting for the phone to come but I'm pretty sure that I got one of these converted ones. I've been reading your posts about converting, rooting, enable DTS. From what I understand, I will need to:
1/ Start at step #4 in the Frankenstein instruction (using REFURBISHED and 20b to obtain unlock bootloader) if my phone already has Nougat.
2/ Upgrade to the latest Oreo 20g
3/ Follow this post to root https://forum.xda-developers.com/lg-v30/help/unlocking-rooting-twrp-magisk-step-step-t3745006
4/ Follow this post to Enable DTS https://forum.xda-developers.com/lg-v30/how-to/enable-dts-3d-stereo-lg-v30-variants-t3887139
5/ Enjoy it.
Is it in the right order or did I mess up between step 2 and 3? Is there any root level adblock? Thanks. I'm using the s9+ but I'm really excited about the V30.

#3 is incorrect. Outdated instructions with old TWRP. Those Instructions were for official bootloader unlock code from LG, which we don't need. We no longer need LG permission to root our phones, plus only a few phones were even eligible under that program. A converted LS998 would not be, nor even most US998.
You want the WTF Instructions. You would use this to unlock bootloader, install TWRP custom recovery and root.
You would merely update from US998 Nougat to US998 20B, install TWRP, and follow the instructions to finish rooting.
After bootloader unlock, TWRP and root on 20B, I would then update to TWRP-flashable zip US998 20G in stages. 20E, 20F, then 20G due to the huge audio changes. (The alternative to this would be to refurbish to 20G, but then you would have to reinstall TWRP and re-root. Let's not do that.)
@JohnFawkes actually has DTS enabled on US998 20F and US998 20G TWRP-flashable zips, through build prop edits -- but you would still need to install the DTS Equalizer.
You have the right idea, just changing the order a bit.

Be sure to read WTF INSTRUCTIONS on web browser, not on XDA app. XDA app truncates sections of very long posts like that.
Print out to read if you can.

If you don't want to wipe your data, then try Upgrade mode in LGUP.
I was just giving you the answer that will definitely give you best results.
If you use Upgrade mode, you can try to go straight to US998 20G...
but if that gives you audio problems, then go to 20E, then 20F, then 20G in Update mode.
You would download and flash the various US998 Oreo KDZ from this thread with LGUP.

I have a ls998 that was flashed to us998 and the IMEI disappeared
Can someone she'd some light on how to fix this?
Thanks
Ok I just got my ATT V30 , works great but wanted to switch to US998 as ATT hotspot dont work, I try to flash us99820g and LGUP and selecting all the partitions, after click start LGUP told me some partitions will change and I click yes (my bad) and after all the process completed the phone is in a boot loop and all I can see is the Android green robot with an red exclamation and the reboots, is there any way to fix it or I sent $130 to the trash can.
If I keep vol - and power it reboots and I can see LG V30 thinkq logo but then the loop starts again.

No it's not bricked.
But you need to read the Frankenstein instructions. You can't just flash other KDZ willy nilly.
For North America variants (except for T-Mobile H932), you have to use Dev Patched LGUP and flash US998 Nougat, then Master Reset, then US998 Oreo.

Thank you.
Phone is now fully working, thanks so much for your help. Please close this thread if possible.
I have a LGv30 VS996 that has been bootloader unlocked using WTF and is currently flashed and working great with a US998 stock firmware.
I would like to use VOLTE/VOWIFI but it is not showing up as an option for me.
My local region (I'm in Asia) uses the H903DS variant of LGv30 and they have a stock ROM for that device which I'm hoping will enable the VOLTE/VOWIFI options.
My question is, will that work? Are VS996/US998 similar enough to H903DS that I can cross flash?

Uhmmm... You can't fully CONVERT any North American phone to any H930* phone like Frankenstein can do to each other with most North American variants, but you can flash parts of the H930DS software to VS996 via Dev Patched LGUP in Partition DL mode. However, you have to OMIT certain partitions, like modems and XBL.
People have done this to flash EU H930 firmware over US998 to get East European languages, etc. Every time you flash an updated H930* KDZ, you would have to remember to omit those partitions. You would NOT be changing any bands like with Frankenstein.
See this guide, but change to H930DS KDZ instead of EU H930:

Mrxyzl said:
Select all partition except the following 3: modem, xbl, xbl 2, click Ok and accept partition changes
Let it complete and restart, if you stuck on LG logo, try reboot again, it will boot completely
Result: H930 30B on a US998 with working network and stuff working (testing on GSM network outside US only, cant confirm Vowifi, VoLTE or any other netwrok stuff.)

Read that last sentence.
Good luck.
My V30 doesn't seem to enjoy being flashed with Android 10, as it bootloops no matter what ROM I decide to use (Lineage, Havoc, Pixel Experience), and now I'm thoroughly stumped on what to do, as I can't find a fix for this issue. My phones bootloader is unlocked via Frankenstein, and I've used the method of flashing over 10d with 30b and having no luck. I've recently come across a post that said to attempt trying 20b to 30b, which I'll try as a last effort to get this working, but I'd still appreciate advice on what to do. Whether it be this last method, a modification of it, or just something else entirely, I'd be forever grateful for the help.
If you need more information, feel free to ask and I'll provide to the best of my ability.

1) You need stock Android 9 (Pie) as a base before flashing any LOS-17 (Android 10) ROMs. But you seem to know that.
There are several methods to update to to Pie US998. See US998 Pie KDZ thread, post #2 and FOUR MORE WORKAROUND in post #6.
2) What variant did you start with? If you have former AT&T H931 or Canada H933, you'll need to do additional prep steps before installing any LOS custom ROMs.
Of course, you've read the V30 custom ROMs FAQ -- before you even unlocked your bootloader -- right? It tells all this and conveys other important information. This FAQ is prominently linked in the WTF instructions, with suggestion to read first, then come come back to finish unlocking bootloader...

Yes, I did read through the FAQ before and after unlocking. My variant is the US998U/V30+, which is why I'm a bit confused. The US998 and US998U are identical, aside from storage capacity, right?
I was following one of the guides you posted that stated:

So for installing the KDZ, I suggest FIRST downgrading to US998 Nougat 10d via Partition DL mode, Master Reset, then Refurbish to US998 Pie KDZ. Here are the steps...
If you have problems flashing this US998 Pie 30b KDZ, see post #6 for FOUR more workaround methods proven to work for some people.
You should probably use this method (DOWNGRADE to NOUGAT first) even if you have TWRP installed. Then reinstall TWRP again after successfully updating to Pie.
KDZ INSTALLATION INSTRUCTIONS
0) Turn off phone, manually go into Download mode before opening Dev Patched LGUP.
1) Using Dev Patched LGUP from THIS thread, flash US998 10d Nougat KDZ via Dev Patched LGUP using Partition DL mode. Select ALL partitions.
2) Master Reset. This is NOT Factory Reset.
3) Boot up to Welcome screen. Turn off phone, manually go back into Download mode.
4) Flash US998 30b Pie KDZ via Dev Patched LGUP using Refurbish mode.
5) Master Reset. This is NOT Factory Reset.
If you did not unlock your bootloader before doing this, then you bootloader is still locked -- because that's what you want. Finished. Set up your phone.
If you had unlocked bootloader before doing all this, you will still have it. Boot to ADB, and PLEASE follow these instructions for re-install TWRP and root!!

So that's what I had done a few days ago, but that's also when my problems arose. I was on the TWRP flashable kdz of 30b for a month or two now after Frankensteining it, but wanted to try out some 10 ROMS, but attempting to flash those ROMs was when I started having issues. Flashing the stock US998 kdzs didn't cause issues, the 30b zip I had been running daily wasn't weird, and the md5s for all the files downloaded matched what was provided as correct. That's why I'm a bit stumped, since I believe I followed all the guides I've looked at to make things work correctly, but this one part is giving me a hard time.
I will try those other four methods, since I don't believe to have seen them yet. I will provide an edit to this post after trying them, thank you.

If you Frankenstein'ed, I'm asking what your original variant is. Frankenstein is to convert North American variant to another, also called cross flashing.
Whereas " WTF" is bootloader unlock and installing TWRP. Some North American variants have to Frankenstein to US998 for fastboot flash commands. Then they can use WTF INSTRUCTIONS. But Frankenstein itself is not bootloader unlock, TWRP and root. It's just fully converting one variant to another. It ONLY works with the North American variants, except for T-Mobile H932.

OK, so you were on LG US998 30b stock Pie successfully.
Put your IMEI into this database and tell me what it says? Don't post your IMEI here, publicly. Just curious what variant it says you have.
https://www.imeipro.info/
If you have V30+ US998 , then it's either native US998U or was formerly LS998U and converted to US998 by you or previous owner if you bought it used.
Neither AT&T H931 not Canada H933 have a native V30+, but I've seen H933 V30+ which were Frankenstein'ed.

Ahh, alrighty, I understand the difference now. So I had Frankenstein'ed to unlock my bootloader, then unlocked it with "WTF".
Also, the IMEI checker reported my device as a US998U V30+, which was what I bought it as used.

Merely downgrading to earlier firmware is not Frankenstein. Frankenstein is fully converting one variant to another. It takes on those different LTE bands, etc. Cross flashing AT&T H931 to US998 gives it CDMA bands the H931 doesn't have, different LTE bands, fastboot flash commands. Same with Frankenstein'ed H933. See screenshot.
If you already had US998 firmware and your IMEI check says it's a native US998U (V30+), then you didn't Frankenstein to US998. You already had US998 with fastboot flash commands. You just used LGUP to downgrade to early US998 Oreo for WTF bootloader unlock, TWRP installation and root and/or maybe you went to US998 Nougat at one point. But you were already US998. You weren't on LS998, AS998, H933, H931, VS996 firmware, at any point in time.
Why you are bootlooping on LOS-17 Android 10 ROMs, I don't know. You don't have former H931 or H933, and you said you were on US998 30b (Pie) when you tried to flash those ROMs.

Merely downgrading to earlier firmware is not Frankenstein. Frankenstein is fully converting one variant to another. It takes on those different LTE bands, etc. Cross flashing AT&T H931 to US998 gives it CDMA bands the H931 doesn't have, different LTE bands, fastboot flash commands. Same with Frankenstein'ed H933. See screenshot.
If you already had US998 firmware and your IMEI check says it's a native US998U (V30+), then you didn't Frankenstein. You already had US998 with fastboot flash commands. You just used LGUP to downgrade to early Oreo for WTF bootloader unlock, TWRP installation and root.

Should I attempt to Frankenstein to a different variant then come back? I was going to try to use the fourth method that you linked to before to try to put myself on an actual US998.

The problem with Method #4 is you are willingly converting to Canada H933. While that might get you back to US998 30b, it will then give you more difficulty in flashing LOS ROMs. You have to go through the tedious extra steps of former H931/H933.

As someone who doesn't necessarily mind the extra preparation, would you recommend it for someone in my predicament? And is there any log file I can provide to hopefully help give more insight?

That's your decision. It should get you back to 30b. After that, for flashing ROMs, you'll have to follow the other instructions for H933 (since you will have converted to that, then converted back).

Though if I am to do that, would I still keep the bands I have at the moment or would I lose them when converting? Would I have to refflash my modem partition(s)?

The method is flash to H933 Nougat I believe, then flash back to US998. You don't stay on H933. You flash everything via LGUP Partition DL mode.

Ah alright, I'll try that. So just to clarify, I'd flash over to an H933, then come back to a US998, and then install the 30b kdz, and that should hopefully fix my issues?

Yes. But read Method 4 carefully. Involves timing and buttons.

LGUP doesn't seem to recognize my phone as a H933 after flashing and rebooting back to download mode, but the phone seems to know it's one when I flash and it says what build it's on and what's being flashed.
EDIT 1: Reinstalling LGUP fixed that particular issue, so I'll have to restart the procedure just so it's as unobstructed as possible.
EDIT 2: Never mind, still the same strange occurrence that happened before. I'll try to move on and see if it'll still work.
Okay so, after a lot of trouble, everything seems to work. I ran Jett's Wifi Backup fix to fix the broken wifi on Havoc, along with the Haumea kernel, and now everything seems stable.
Thank you for your help!!
I guess I just had to keep doing the procedure until it stuck
Hi guys, I'm a bit lost too.
My phone is a V300S that is Frankensteined to US998 with V300S modem, bootloader unlocked and installed TWRP.
However i also faced the problem of installing Android 10 based roms causing bootloops, I've seen on the Custom ROMs page that i needed the lastest stock Pie blobs, which is what i have currently (30b)
Is this variant using a different way for custom ROMs? Or did i do something entirely wrong on Frankensteining?
Edit: silly me recently saw that i need to convert my V300S to H930, not US998... I guess I'll try that first
Update: well everything went south, now i can't go back to US99830b anymore, stuck at V300s Oreo. I guess I'll start everything over again, but if there are things or procedures i needed to know, please, any help will do
