So hi guys, I'm brand new here and don't know anything with new techs so I hope tht someone can help me out with this.
I just bought a V30+ this morning, and the IMEI is : 358166081226505, LG-H933 and S/N is 709KPPB0008640,.
I don't know how to check if this phone is legit or not and I don't even know which carrier it's belong to, because I bought it from a supplier who brought it from abroad ( I'm from Vietnam ). So can anyone help me to track where is it from ?, and is it legit or not ?
Besides, It's work complete ly fine with my local Vietnam's SIM card so I don't even know if it's unlocked or not, but when I tried to manual update the phone said that : " Device is not registered". I've tried googled up many method but nothing worked, including factory reset... Any help on this guys ?

You have Canadian V30, if H933. All the carriers in Canada use the same model. Software loads depending on Canadian SIM card used.
ARE YOU SURE IT'S H933?
They don't have V30+.
It's either not H933 or is not V30+, just V30. Which is it?

It's not possible to have V30 plus H933. The H933 is the V30. Maybe is counterfeit or an refurbished phone.
https://forum.xda-developers.com/lg-v30/help/software-update-phone-registered-to-t3723704
I think same situation with mine.
Long story short,
The phone should be on the provided carrier at least once.
If not, it happens.
only way to fix is inserting active sim for original carrier, in this case you should go to Canada.
or, find H933 KDZ files and manually update it. you can find how to do from https://forum.xda-developers.com/lg-v30/development/us998-lg-v30-market-us998-t3736910.
but DON'T USE US998 KDZ! you have to find H933 KDZ.

Well, not quite the same as yours. He has a phone that doesn't officially exist. An H933 V30+.
H933 is "Canada", but they have no V30+ -- only V30.
I'm in Canada and I have a H933 and its 64GB V30. All the new phones sold in Canada are carrier unlocked due to bew laws that is why it is working with your carrier.
You mentioned buying it off some supplier, the only thing I can think of would be that you got a refurbished unit. I don't even know if swapping a 64GB storage on V30 (H933) with a 128GB unit would work (since the OS and everything should be on that storage chip) but that is the only thing I can think off to explain the situation. Plus, a back panel saying V30+ with a H933 brand kind of suggests a refurbished unit since V30+ is not sold is not available in Canada.
Return the unit and get your money back!

Actually, the V30+is just a V30 with 128gigs of storage and a decent pair of earbuds. The "+" is just marketing. H933 is the Canadian V30. Carries or retailers may sell it as a "Plus" but it will have the same model number.

It is just marketing, but there's no official V30+ for the Canadian H933. No carriers or retailers sell it.
It's either not an H933, or it's not a real V30+.
Which means someone took a H933 V30, swapped out the internal 64GB storage for 128GB AND put on a V30+ back panel. A Frankenstein phone. DING. DING. DING.
He bought that "Canadian" phone in ASIA, so who knows how it got that way...

The 128GB version was never offered by any carriers in Canada. I am not sure if LG Canada actually sold them directly though.
The H933 is carrier unlocked out of the box. Have you tried another SIM card just to test it, even if the SIM isn't activated? If the SIM you are trying to use activated? Stolen phones are blacklisted in a database that spans most of the US and Canadian carriers in order to combat phone theft. Have you contacted your carrier to verify the IMEI and serial number is not stolen? I highly recommend removing your devices serial number and IMEI as well from your post.
Edit: There is one other thing you can try that might help. Go to the LG Dialer and put in *#546368#*933#. This should open up to a group of 4 menus. If it doesn't, it isn't an H933. If it does, go to Field Test, Modem Settings, and LTE-A CA setting. In here, you want to select the top option, which is, CA Enable/ SupportedBandCom.. (All Enable). You will need to reboot the device for this to take effect. When it boots, you will see an unlatched lock with a blue thing moving around it in a circle. This should disable carrier aggregation and allow the phone to search all bands it supports for service.

There's nothing wrong with your phone.
This has been thoroughly discussed in the US998 Pie KDZ thread. And digging up a 1.5 year old thread which has nothing to do with Pie is ridiculous.
Go back to the US998 KDZ PIE thread and READ the workaround Installation methods. There's THREE of them.
my lg v30 cant update via ota
Thanks have already checked on that but didn't work for me unless I unlock it to use the TWRP method

Yeah, there's three workarounds. If none work -- and you have NOT tried them all yet -- you have to wait for another KDZ.
Read bottom of screenshot, which you should have read earlier. There's no other answers.
my lg v30 cant update via ota
Yeah that what they said because I tried lgup Dev patch with other kdz nougat and Oreo it work fine only the pie giving me issues so I was told to wait for another kdz and even the pie is not stable and lags so I guess that why it not working for all except unlocked ur bootloader then flash TWRP then flash the TWRP us99830b that works for everyone but in my case don't want to unlock the phone now I just want it to be stock always since it aosp base and like the customization of lg with many features so there is .of point using custom roms I use custom roms on my mi 6x so I get pretty much tired because of battery life and heating issue so I prefer stock it fine ? and I love aod too ??

After searching the forums this seems to be an LG specific issue and dates as far back as 2012 on some models, however the suggested solutions have not worked for me, so I am hoping that there may be another way around.
So I got a US998 (carrier unlocked US) V30 and I stuck my cricket wireless sim in and all works flawless. When I try to do a software update I get the message 'Your phone is not registered yet'. So OK, I go online and register the phone using the model code and IMEI, but still no luck.
Then I followed the suggestion of installing LG PC Suite, which tells me that this phone is not compatible and I should use LG Bridge. That connects but gives me in a nutshell the same issue that it cannot get an update due to some issue.
One suggestion was to use the main carrier sim, which in my case would be ATT, but I don't know anyone who has ATT as service. I guess I could ask some random strangers if they are on that service and if they would be willing to let me use their sim in my phone, but unlikely.
Has anyone encountered this issue and what did you do to get your phone to update?

There's no update for this phone yet.
By the way, I use AT&T SIM card for AT&T Prepaid. Same exact SIM card as AT&T postpaid (contract) customers.
Not sure why you are getting that error message. When I check for update, it says I have the latest software. I didn't register anything online, didn't connect to any software.

I am on Cricket, which operates on ATT network, is even owned by ATT, but apparently is not recognized by LG as one of the carriers.
As I said, others all the way back to 2015 suggest to remove the cricket sim and insert an ATT sim, which apparently registers the phone properly on ATT's network and thus allows for OTA's to occur.
I am aware that no current updates are out, but when they do I don't want to be stuck on 7.1.2. Anyway, I will ask around at work when I get back next week. There are bound to be some folks around that use ATT.
I'm using ATT post paid monthly plan with an old sim card from my previous phone, and it works fine on my us998. However, for some reason, on myatt page this phone is not being recognized, so I went to att store and asked someone to help me registering this imei in their system, but after they entered my imei they say this number is unknown to their system, so it can't be registered. I don't know whether that will cause any problems in the future, but since the system updates should come from LG but not att so it should be fine.

My AT&T SIM card also worked fine but I wanted to make sure I was getting the fastest speeds, so I took the phone to AT&T store and registered it in their system. Since AT&T also sells a branded LG V30, there was no issue registering it. They know what an LG V30 is. They just needed the serial number.
Whereas three years ago, for both mine and my wife's Moto XT1225 (international version of the Droid Turbo) which I imported from another country, I told them to register it as a Moto Nexus 6 -- closest they had in their system. Same manufacturer, 90% same specs, just a more reasonable size of the Moto Nexus 6. That worked.
You are right that system updates for the carrier unlocked US998 will come from LG and not AT&T or any carrier.

So neither one of you is getting a pop up message when you try to do a manual check of software updates (see the attached images)?
Yesterday I registered the device with the 14 digit MEID hoping that was the trick to get rid of the message but no luck, today I added the IMEI which adds a digit as a second product on LG's support page. Maybe that is what I am missing.
I'll contact LG next to find out what is going on. I can also not take advantage of the 2 year warranty as the guy I bought the phone from won it during a LG promotional event in NY so no purchase receipt apparently exists. Oh well.

LG UP might be an option for me I guess if I can't get this worked out. I am new to LG phones so gotta do a little reading up to understand how that all works. Guessing it is similar to ODIN on the SGS phones that I am used to.

I just set up my 3rd carrier unlocked LG V30/V30+ last night. For each, when you go to the software update section you have to agree to all the legalese the first time. You did that? Several boxes to check and agree to before it will check for updates.

Of course, as mentioned before I'm using AT&T Prepaid SIM cards. Real AT&T, not Cricket. And yes I know AT&T owns Cricket. But there's a reason you'll never see an AT&T logo anywhere near a Cricket store, and they don't let Cricket use the same AT&T SIM card postpaid/prepaid users do. Cricket is configured as an MVNO. I don't know why that would matter in this case, but possibly some way AT&T botched something else with Cricket?

Tell me where you bought your phone? You say "carrier unlocked"...
Is it...
* "open market" US998, official carrier unlocked model bought from authorized retailers like B&H Photo or Best Buy --
or is it...
* the unofficial carrier unlocked model from U.S. Cellular? Either bought from them or through eBay seller?
They are both "US998". But if from U.S. Cellular, then technically it is a carrier phone. Which may affect how updates are checked, distributed.
Just throwing out ideas.

So after checking again, you are spot on. This is the US Cellular version, so now what? I am stuck not being able to take updates unless I become a USC customer?
I bought the phone from an ebay seller who won the phone during a LG promotion in NY and he states that it was unlocked, which I can confirm since it took my Cricket Wireless card without any issue, but not being able to update will be a big worry for me.

Others have bought the U.S.Cellular model to use on other carriers, and they haven't posted any issues -- but they bought from U.S. Cellular itself. Whereas this one was a prize in a contest given by LG. So, maybe it's not "registered" in U.S. Cellular system like ones they actually sold? Basically something has slipped through the cracks.
This sounds like a Tier 2 support question for LG customer service or U.S.Cellular.
Sorry you're going through this.

Thanks for the support. I will give LG a call and see what can be done. The nearest USC store is about 3 hours away, so that doesn't seem like a fun option.

Hello,
I also would like to know, I am on the same boat.
I got it used, the previous owner said he won it from LG event.
This is US Cellular version US998, but I can use it on my AT&T.
The thing is there is no US Cellular branch in southern CA.
Please post how you do.
Thank you so much!

One more question... Did you disable anything? Alleged bloatware, maybe important services? Using ADB script or that disabler app?
That's something else that could accidentally mess up updates.

Factory reset performed and checked all the boxes during signup... still no luck.
I guess next step is to get LG's attention and hope there is a fix for this.
The other odd thing is that I cannot get LG Mobile Support tool installed.
Downloaded the drivers, installed them no issue. Then downloaded the tool and it always gets stuck during the installation process with an empty popup alert window. with a button that has not description, but when I press it the popup closes and the installation stops.

Been asked a million times. You can update it in 5 minutes with latest US998 Oreo KDZ posted in this forum, once you install LGUP. Latest as of this moment is US998 20H. Some of the answers below are over the PAST YEAR, so you may see older Oreo KDZ mentioned. It's the METHOD that's important, that is the same.

I would add that you can also use LG Bridge, which is their official tool for backup and phone updating.

You can do other, more hacky and sophisticated things with LGUP, including rolling back to previous Android versions. You can also do things you shouldn't and which you'll regret. That's almost impossible with LG Bridge.

You can do other, more hacky and sophisticated things with LGUP, including rolling back to previous Android versions. You can also do things you shouldn't and which you'll regret. That's almost impossible with LG Bridge.

But you can't always use LG Bridge to update firmware...
* If it's former North American variant converted to US998, LG Bridge still sees the "LS998" IMEI or whatever. So you have to manually update through LGUP with downloaded KDZ. Same thing, you're just doing it manually. (Same reason these converted US998 probably don't receive OTA updates?)
They're still US998, there's nothing "wrong" with them, except manual updates. I just bought another converted LS998/US998 V30+ recently. I think I'm addicted... It's flawless condition, by the way.
* Also, even with native US998, I've had LG Bridge tell me I have the latest firmware -- when I don't. So, again LGUP is the answer.
Good points, Chaz. Until recently I always used LG Bridge myself, easy peasy. But I can see with so many Frankenphoned LS998 in circulation, that LGUP is a more predictable advice.
And, ahem... Yes, you may in fact qualify as addicted. How many of these are you up to now?
But they really are a great value at this point, no doubt.

Besides my wife's and my B&H Photo native US998 V30 (64GB) and V30+ (128GB) which we use daily...
I have one new (yes, actually new from Wal-mart) V30+ in box, and this recent mint V30+ off eBay. Both are former LS998 V30+ converted to US998 V30+. (Yes, came from Wal-Mart that way.) I tell myself these two are backups, in case of emergency. I probably only need one -- not two -- but I couldn't resist buying another.
I ALSO have a mint 2018 AT&T LG V35 flashed to Google Fi firmware, which I've taken out of the box once. I'm not sure what to do with that. I was hoping we would get bootloader unlock, TWRP, and root for the LG V35. There is some kind of remote bootloader unlock and root available, but not TWRP that I'm aware of...
All the other LG V30/V30+ I gave to family/sold to friends.

I recently bought an LG v30 US998, however I'm thinking it may be a converted H931 because of an AT&T logo on the back. Is there a way to tell for sure which version I got?

If it was flashed to US998 firmware, it's now US998 -- including all bands, etc.
It is now carrier unlocked and you can manually flash any US998 updates. I've converted a few Sprint LS998 to US998.
If you are merely curious if it was originally AT&T H931, you can do an IMEI number check on any of several online databases.
____
The only drawback to former AT&T H931 converted to "native" USS98 is same as former Canada H933 -- both need lots of extra prep to run AOSP/LINEAGE custom ROMs, if that's what you intended to do. (I run rooted stock firmware, so it wouldn't bother me.)
Both have to be at least temporarily converted to US998 for bootloader unlock and root.
I do intend to run LineageOS on it, so that's where my concern lies

Then return it.
Most US998 you will see on eBay are former something else. Usually LS998.
If you use Swappa to buy, they don't allow converted phones. IMEI has to match.
I use eBay, because I understand the market and I don't care if it's a converted phone -- especially if it was a former LS998 V30+.
You should get US998 V30+ (128GB). It can't be former H931/H933 as those models only came in 64GB.

I checked an IMEI TAC database, and while most didn't have it listed, the one that did said that it was a H931. Oddly enough I did buy it from Swappa, so maybe they changed their terms (or possibly didn't have the TAC in their db). I'll be getting V30+. I believe the right model number is US998U? Thank you for your help
I was able to figure it out only by creating an account on the LG website. When I did that, I found it WAS a Sprint phone prior to my purchase, but had already been Frankensteined.
Somehow this affected the OTA updates for me, but I'm not sure how
I picked up a V30S and now I have rooted it successfully. However, during the conversion from US998h to VS996k in TWRP, I lost the "S" part in the boot, and now it just says "LG V30 thinq" whereas it used to say "LG V30 thinq", like the attached picture.
I would like to get that back. I liked seeing the "S" part when it boots up, it feels more premium.
The same thing happened with my V30+, it lost the "+" once changing to VS996.
How can I get this original factory boot screen back?

You can't get that back on Verizon firmware. Verizon didn't sell the V30+ nor V30S, only the V30.
You can get original factory boot screen back by flashing back to US998 firmware.
Which is what you'll do when you sell it eventually, but until then it doesn't really matter.

If you could do that, people could claim to have V30+ who don't...
Good luck with that. Don't brick your phone.
I already know you can edit the other boot, so by the way I already know it is possible to put a boot screen of anything, after the initial boot screen, so your argument is pointless.
As far as tricking someone, anyone can look up the IMEI to find the true model of the phone. Also, you can look at the storage. If you put a "plus" on a 64gb non-plus that would be STUPID since both phones cost nearly the same.
Looking for someone to actually help. I do have the actual phone and I could show my IMEI to prove it. I bought this second phone for the 6GB of ram (I now have a V30 Plus AND a V30S). I looked for months to find one. Part of why I'd like to see the S in the boot screen since I put a lot of effort into finding this phone. I have no intentions of ever selling it. It's the perfect phone for me and I could see keeping it for many years.

Yes, the V30/30+/v30S are fantastic phones. Congratulations on finding a V30S. A year ago when I was looking they were still too expensive and already have several V30/V30+.
I wasn't talking about YOU tricking someone, I was just talking about in general. Someone recently posted they want to do that, so people would think they v30+ when they only had V30. Don't know why, they weren't talking about cheating someone, they were talking about just bragging about it.
Lots of people have asked what you have, nobody's been able to do it.
Same thing with getting rid of the bootloader unlocked warning. The only way you can that is to do is what you did -- flash Verizon firmware. OR flash partial Verizon firmware -- which is dangerous for other variants because every time you update your firmware, if you don't match compatible firmware you brick your phone.
Good luck in your quest.

Yes, it (V30S) was hard to find. You can buy it from the LG website for a remarkable $900 (!!!) but of course that's not the real price. Heck they are selling a new V30 (regular! 64gb) on the LG website for over $900! LOL! I love my V30S, but it is not a significant improvement. It's nice to have a little more RAM but it's not any different at all besides that. Speed is pretty much the same. Only difference is marginally better multitasking. Worth it for me, but I wish I had 24GB of RAM lol. Heck I want 1 million gb of ram with a trillion petabytes of storage and a 99999 core neural network quantum cpu but hey that's a nice dream.
Actually, I already removed the bootloader unlocked warning. It disappears when you flash the Verizon variant, not sure if that's what you meant, but I have no warning anymore. Also, I had already removed the verizon boot as well, this is easy with ROM Toolbox Lite (choose "hide" not remove).
To clarify for readers, flashing to VS996 (verizon) from an LS998 or a US998 or even US998R (V30S, my current phone), is 100% safe. I've now done it on 3 phones. 2 of them former LS998 converted to US998 through the WTF method and then VS996. And 1 of them my US998R.
(p.s. you may get easily fixable bootloop if converting LS998 on PIE (Android 9) downgrading to US998 Oreo to prepare for bootloader unlock. You can easily get out of bootloop by holding voldown + power for 7 seconds until reboots, then at reboot logo keep holding voldown and then release power for a half a second and hold power again, then do the factory reset and it will get out of bootloop).

Yes, that was what I meant. Verizon firmware doesn't have bootloader unlock warning because Verizon never imagined their phones could be bootloader unlocked. . Of all the 20 variants, only stock VS996 doesn't have bootloader unlock warning (that I know of).
So some people who don't want Verizon firmware but wanted to get rid of bootloader unlock warning started flashing just that specific VS9996partition governing that in Dev Patched LGUP -- and someone bricked their phone.
Because they kept using the same Verizon firmware but didn't realize as their variant is updated they had to also use updated VS996 firmware to replace that partition. (Sort of the same reason you can't be on early Oreo to flash current LOS-16 ROMs.)
Anyway, Devs said to stop doing that, it's not worth the risk.

I agree it's not wise to flash only part of a firmware. Better to flash the whole thing. You can get Verizon firmware to work on most other providers anyway as a bring your own device.
Just keep in mind Straight Talk does not like Sprint phones (you can find out your original model number using LG Mobile Support Tool, which, when plugged in, will tell you your ORIGINAL hardware model number, not your software model.) My friend has a V30 and Straight Talk was a disaster. I would say don't bother with straight talk.
Just use prepaid Verizon instead if you're trying to save money. Activate a legit Verizon phone first and then transfer the sim card into your phone. I was able to get both a V30+ and V30S to easily and seamlessly work on Verizon on VS996 firmware on BOTH prepaid and postpaid plans.
But as for flashing the full VS996 firmware, it will be perfectly fine on compatible models (e.g. LS998, US998, US998R, possibly others but I have not tested).

Sure. I'm the one who wrote the Frankenstein instructions which came BEFORE WTF bootloader unlock exploit.
All the North American variants (EXCEPT for T-Mobile H932) can be completely cross flashed and converted to another: US998, AS998, LS998, VS996, H931, H933, and H932PR (Puerto Rico).
However, of all those, only US998 has fastboot flash commands.

By the way I'll probably keep this phone until a fully rootable phone on verizon 160g or less weight with a better resolution screen 6.4" or bigger yet not any taller, with better cpu more ram and oled with microsd card slot and a few other specs comes out, and WITHOUT a notch or cutout.
So, I expect it will be years before such a phone comes out. Until then, this phone is the perfect phone for me.

No, it's not.
The B&O logo on the back gives it away. LG is not allowed to distribute B&O branded phones in North America, as another company has those rights.
AT&T H931 V30 is 64GB and has silver back that says 'V30" and "LG".
B&O branded phones were sold in Europe and Asia.
Go to IMEI online database like SWAPPA and check your IMEI, to see where it originated.

I didn't say or wasn't an LG V30 phone. I said it wasn't an AT&T H931. Nor any V30 sold in North America -- since it has B&O logo. That was your question, "Is this a genuine AT&T H931?"
NO. It is not. Some Octoplus dealer has probably flashed AT&T firmware over it and since it may or may not have have native AT&T IMEI it's not going to successfully update.
What SPECIFIC MODEL VARIANT does the IMEI database say?
* Maybe EU H930?
* Maybe some Korean carrier variant?
If SWAPPA doesn't say, then Google some other IMEI database...
No disrespect, but I'm not even going to look at that link you posted. I already know which regions LG is allowed to use the B&O logo and where they are not, and why. I know more about this phone series than any website writer.

You've obviously bought some refurbished phone where they have European or Asia B&O back cover. No LG AT&T phone came with that logo and never will.
Additionally they may have flashed AT&T firmware over it. Maybe they used AT&T IMEI.
I don't know all the extent it's not genuine -- the back cover is enough proof.
Someone else last year bought an "AT&T H931" which would not update from some eBay dealer. When he told the dealer it didn't seem genuine, as it wouldn't update, the dealer didn't even try to argue. They offered full refund.
Here's your choices: you can return the phone or you can flash it to North American LG carrier unlocked firmware and update it yourself. It can run on AT&T but won't have AT&T VoLTE, etc.
If you need/want genuine AT&T H931 with updated firmware, you need to return it and see if they have an actual AT&T H931 they can send you.

Real AT&T H931:
If you have no intention of bootloader unlock and root, you can go to Pie.
If you bootloader unlock, you have to TEMPORARILY downgrade to early Oreo. Then update back to most recent firmware, which for XDA H931 users is only last Oreo. AT&T only updates OTA for customers and only on pure stock. We have last AT&T Oreo made by devs but not AT&T Pie. We do have other Pie stock ROMs made by devs for other carriers and for carrier unlocked.
OTHER:
If you use North American carrier unlocked firmware, in my opinion there's really no advantage to Pie at this point in time. I'm still on last Oreo, which is rock stable. But I'm running rooted stock US998 firmware on AT&T. I don't have VoLTE or Wi-Fi calling, because it's not a branded AT&T phone.
Conclusion:
Do NOT stay on early Oreo firmware. Too many fixes and additional features on latter Oreo updates.

Is the last Oreo made by devs an at&t firmware that have wifi calling and volte?
From my experience, I believe this phone is opened and have different parts assembled from different carriers. For example, It's board might be genuine At&t and back cover is changed to international B&O. It is also possible that screen might be from any korean variant. This happens to old phones and no one can guarantee you the genuity.

Interesting. While it IS possible the previous owner swapped out the back cover (you can buy them on eBay), not many have done that...
You can buy a V30+ back cover for your 64GB V30 to fool people.
You can even buy a black AT&T back cover!
It just seems very strange the OTA update doesn't work. It leads me to believe something has been done to it or it's not genuine. But maybe it is and the previous owner just "customized" it.

Yes. The last AT&T Oreo stock ROM (TWRP-flashable zip) does have AT&T VoLTE and Wi-Fi calling for AT&T customers. BUT, AT&T has to be convinced it's an AT&T H931 phone for those features to work. Has to be enabled on their end. I have a rooted US998 phone with AT&T SIM and I do not have those features. Even if I flashed the AT&T dev-made H931 Oreo ROM to "convert" it to H931, AT&T would still look at the IMEI and the Device ID and not enable those features.
If your phone can pass the AT&T sniff test, then you could bootloader unlock and root, then flash back to this firmware below and have rooted stock AT&T Oreo firmware:
LG V30 AT&T H931 Rom
https://forum.xda-developers.com/lg-v30/development/lg-v30-att-h931-20f-rom-t3872926
The dev was not able to make an AT&T Pie stock ROM as there were too many changes in Pie. He had to UNroot his phone, take the OTA, then merge it with a base framework and create a KDZ. Both AT&T and Sprint refuse to publicly release full image KDZ of their carrier firmware. They only let customers have partial image OTA updates.
As a result, many people who have bought AT&T H931 in other countries (where there is no AT&T) convert their phone to open market US998 or even carrier unlocked Canada H931 firmware. (It's called Frankenstein.) Then they can manually update their phones themselves, when new KDZ are released for those variants. We post those KDZ here in this forum.
You really only want AT&T firmware if you are an AT&T customer. I am an AT&T customer and I still don't want AT&T firmware. I prefer the Open Market US998 rooted Oreo, but that's my personal opinion.

Yes. The last AT&T Oreo stock ROM (TWRP-flashable zip) does have AT&T VoLTE and Wi-Fi calling for AT&T customers. BUT, AT&T has to be convinced it's an AT&T H931 phone for those features to work. Has to be enabled on their end. I have a rooted US998 phone with AT&T SIM and I do not have those features. Even if I flashed the AT&T dev-made H931 Oreo ROM to "convert" it to H931, AT&T would still look at the IMEI and the Device ID and not enable those features.
If your phone can pass the AT&T sniff test, then you could bootloader unlock and root, then flash back to this firmware below and have rooted stock AT&T Oreo firmware:
LG V30 AT&T H931 Rom

The dev was not able to make an AT&T Pie stock ROM as there were too many changes in Pie. He had to UNroot his phone, take the OTA, then merge it with a base framework and create a KDZ. Both AT&T and Sprint refuse to publicly release full image KDZ of their carrier firmware. They only let customers have partial image OTA updates.
As a result, many people who have bought AT&T H931 in other countries (where there is no AT&T) convert their phone to open market US998 or even carrier unlocked Canada H931 firmware. (It's called Frankenstein.) Then they can manually update their phones themselves, when new KDZ are released for those variants. We post those KDZ here in this forum.
You really only want AT&T firmware if you are an AT&T customer. I am an AT&T customer and I still don't want AT&T firmware. I prefer the Open Market US998 rooted Oreo, but that's my personal opinion.

I put my at&t sim in the phone and I was able to use wifi calling and volte. Does that means that with the dev firmware I can still use those feautures?

This is what I understand I have to do after reading the link you send me:
LG V30 (H93120c) -> FRANKENSTEIN (NOUGAT US998 then Oreo US998) -> unlock bootloader -> Install TWRP -> LG V30 AT&T H931-20Q ROM

Yes.
There's also couple of other files you flash with TWRP -- encryption disabler and root check disabler, but it's described with the WTF instructions.
