H932 - why no AOSP 10 yet? - LG V30 Questions & Answers

Probably a stupid question, but just trying to understand why no 10.0 rom can boot yet on the h932. Curious if it may not be possible on this variant for some reason. Thanks.

First you need to look at the history of the T-mobile H932.
1) The T-mobile H932 has different RSA encryption, is an island unto itself. With the other variants, especially North America, you can cross flash to actually convert (Frankenstein) to those variants. US998, AT&T H931, Sprint LS998, Verizon VS996, Canada H933, regional AS998 are all totally cross compatible as long as you follow the Frankenstein instructions; you can convert to any of those models gaining all the respective CDMA/HSPA/LTE bands of that different model.
Between the various H930 variants, the North America and the Asian variants you have somewhat less compatibility. However, you can still flash other stock firmware -- but have to omit certain partitions (like modem, which cancels out the reason most people want to cross flash).
With T-mobile H932 it's totally different.
This is why the T-mobile H932 can't use the WTF method to unlock bootloader, install TWRP and root. (It can't convert -- even temporarily to US998 -- for necessary fastboot flash commands.) T-mobile H932 only got root three months later through genius @runningnak3d LAF exploit, which is totally different method. All other V30 variants use WTF exploit (unless eligible for LG's official bootloader unlock -- but even many of those use WTF as it's easier).
The first dev who created the LOS tree for V30/Joan (SGCMarkus) owned an H930. It was relatively simple to then make "H930" LOS compatible with all other variants -- EXCEPT for T-mobile H932. "H390" LOS ROMs are really "V30" or "Joan" ROMs -- except for T-mobile H932. Stay on latest stock firmware for your variant and just flash LOS ROM + Magisk.
2) For T-mobile H932 the main LOS tree was NOT compatible. There's a separate T-Mobile H932 LOS tree.
For LOS-16 ROMs, initially, Devs had to create both the "H930" (all variants except for T-mobile H932) and then create completely separate "T-mobile H932" ROMs. A few devs did this, but it got tiresome.
3) Then SGCMarkus created a zip file T-mobile H932 users could flash AFTER installing LOS-16 "H930" to implement the changes needed to make it compatible with T-mobile H932. A conversion zip, so devs didn't need to create separate T-mobile H932 ROMs He looked at the differences between the regular "H930" LOS-16 ROMs and the specific "T-mobile H932" LOS-16 ROMs and his conversion zip turned H930 ROM into T-mobile H932 ROM.
Now, all T-mobile H932 users could use ANY LOS-16 ROM!
4) But with LOS-17.x (Android 10), this LOS-16 T-mobile H932 conversion zip no longer works. Also, no dev has come along to make a separate LOS-17.x T-mobile H932 compatible ROM, so SGCMarkus can make a newer conversion/compatibility zip. He's also working on V40 and V50 ROMs, besides being in university full time... So he would need a dev to create a T-mobile H932 LOS-17.x ROM to begin, with so he could have a blueprint for any possible LOS-17.x conversion zip. Even then he would need to find time to do it.
5) There was a dev (@ShapeShifter499) who was working towards that goal. He had T-mobile H932 and had even updated LOS-16 to current security patch. He had even made SEPARATE T-mobile H932 updated LOS-16 ROM.
He was very energetic about it, and his eventual end game was to start working on LOS-17 ROMs with SGCMarkus to make them compatible with T-mobile H932. (He wasn't actually a T-mobile customer, I don't believe, but he had "accidentally" bought a T-mobile H932). But then he bricked his phone experimenting, trying to cross flash other stock Pie V30 variant kernels (or something like that). The different RSA encryption is a bear and the notes in LG's Pie kernel source code are not clear. The LG notes make it seem that with Pie kernels, the RSA incompatibility no longer exists -- but it does. I think he got a US998 V30+ as replacement, so I don't believe he is working on that anymore.

I know what I did wrong but I was able to return the phone and will be getting another soon.
I probably will not get another h932 model so I can't support that.

Mostly correct but I do not have a new v30 yet of any kind yet. I ended up needing the money I got from returning the device for other things more, then also there's this virus thing. So I don't know when I can obtain another. I'm on the telegram chat for v30 owners if anyone wants to help or ask any questions about support.
I do have T-Mobile, it's through a third party so I don't pay them directly but the SIM I use is T-Mobile.
EDIT: In the mean time I have a old Google Tango (Yellowstone) Tablet that works fine with the T-Mobile sim, no calls which sucks if there was ever an emergency but I don't actually call much to matter.

What roms are you running? I've been running BoomBox with no issues but I'd like to run a rom that has WiFi calling. What roms are you running for your TMobile service? How stable?

You're talking about T-Mobile users on US998 (either converted or original) or T-Mobile users on T-Mobile H932?
Because there's a vast difference what ROMs can be run, depending on the model you have. T-mobile users on newly rooted T-mobile H932 can't run ANY custom ROMs right now.
But there are lots of T-mobile users on US998 (either converted or original). Depending on what they converted from, they can run custom ROMs. However, former H933 and H931 converted to US998 cannot run AOSP custom ROMs -- but can run stock-based custom ROMs. Original US998 or converted from Sprint LS998, regional carrier AS998, Verizon VS996 have no such restrictions.

This one seems good. I have WiFi calling and it's running smooth on my US998 with T-Mobile. Lastest Magisk is good as well. ?

That's just stock US998 20D. @westwood24 made it into a TWRP flashable zip file, so you can flash it like a ROM.
It's great for updating like from 20A or 20B, after bootloader unlock, installing TWRP.
You can get the same firmware by flashing 20D KDZ... But it's harder than just flashing that with TWRP.

Interested in seeing it when it's finished
US998 seems to be working with T-Mobile wifi calling well. I tried to enable it on At&t and it told me that I have not configured my T-Mobile SIM right. It's obvious that that this is designed for T-Mobile wifi calling.
Anyway to get this enabled for 9 GSI?

Crossflashing H931 (AT&T) to H930 (Open EU)

Hi!
I would like to flash my unlocked AT&T (branded) H931 to an Open EU H930.
Is this possible? Anyone tried that?
Can I just update the phone in LGUP with the H930-KDZ?
Thanks in advance!

No. Don't do it.
You can only safely flash North America variant to other North America variant. Even then, T-Mobile H932 is off limits.

@TxanMoe who discovered the WTF method bricked his phone trying exactly that -- going from North America AT&T H931 to Europe H930. @runningnak3d had to help him recover back to US998.
North America variants should stay North America. There's plenty of North America variants you can flash on H931-- US998, AS998, H933, VS996.

You need to follow the Frankenstein instructions. There's a specific order to do the flashing and you use Dev Patched LGUP. To convert H931 to US998, you have to flash US998 Nougat first, do a Master Reset, then flash US998 Oreo. It's all in the instructions.

Is unlocked H931 free to use on other operators without flashing?
What is the purpose of installing another rom if yes?

If truly carrier unlocked and still H931 firmware, you CAN use on other operators -- but you still won't get updates. AT&T only gives updates to customers on their network and they don't publicly release KDZ. They only give OTA updates.
Bottom line: only AT&T customers want H931 firmware... For everyone else, it's useless.
By using Frankenstein method, you convert H931 to a North America carrier unlocked model which WILL receive KDZ updates. There are several North America carrier unlocked variants, but US998 is most popular.
Also, H931 doesn't have fastboot flash commands, so can't be bootloader unlocked and rooted as "H931". (But you can convert back to H931 after bootloader unlock and root, if you wish -- using a TWRP-flashable H931 stock firmware ROM.) Of all the North America variants, US998 has fastboot flash commands.

I'm an att prepaid customer. Will it have adb after flash to us998 and bootloader unlock, and then flashing back?
Is it true that I want to flash back to h931 because there are two lte bands I need enables for full coverage?
I'm assuming there are no ways to enable those radios while on us998?
Will this work the same with the ls998 v30+? Ie., flash to us998, unlock, root, flash to h931 to get my bands?
Thanks

If you read the part you quoted... of the North American variants, only US998 has fastboot flash commands. But if your bootloader is unlocked on US998 and you have TWRP installed, then you can flash H931 stock ROM (aka TWRP-flashable zip) to convert back to H931. Then you will have all the H931 bands.
With TWRP installed, you don't need ADB any more. We are only using ADB to unlock bootloader and install TWRP.
I think it's fair to point out that once you convert H931 to US998 by flashing the US998 KDZ, you can never fully convert back to H931, as no KDZs are available from AT&T. You can flash the H931 ROM with TWRP, but not the full firmware.
For most people that's not a problem, as US998 is superior to H931 in almost every way.
Only concern would be that you'd never receive OTA updates again, even if you're an AT&T customer. All updates will have to be manual (which I prefer anyway, but some people may be different).

Right, but the AT&T customers (very few) are people who want unlocked bootloader and TWRP. They can get that, and with TWRP-flashable zip, can also get AT&T features and those two extra bands back, IF they are AT&T customers.
However, most of the people (like the person who started this thread) who buy these H931 are NOT AT&T customers. This person wanted an EU H930, but got an H931 because it was probably cheaper.
These 2017 H931 phones are being sold around the world on eBay or eBay type sites as "UNLOCKED" LG V30 H931. Yes, they are carrier unlocked by code -- but will not receive updates for these owners who live all over the world. The only way to do that is to convert to another North American variant and use LGUP to update. The best choice is US998 firmware. (And just converting to update has nothing to do with bootloader unlock and root -- which some people don't want to do, they just want updates.)
These people don't care they will never be able to return to unrooted, bootloader locked stock H931 AT&T firmware -- as they can just sell the phone as pure stock bootloader locked US998 on eBay or whatever. The same way converted LS998 V30+ are sold as US998 V30+.

I think you know I agree with all that. If I had an H931 myself, I would convert it in a heartbeat. If my H932 could be converted to US998 I would do so too (despite loosing band 71).
But not everybody is the same. For example, while I know it wasn't a concern to you, preserving my 2-year warranty was necessary for me in case of hardware issues, and held me back from rooting for almost a year. To others, downloading KDZs from a non-LG site and installing them with Dev Patched LGUP -- simple enough for you and me -- may seem rather involved compared to receiving an OTA update. And yet others may want to be able to sell their phones as complete stock to a user who has absolutely no idea what we are talking about on XDA, and who expects OTAs like if they'd bought the phone from AT&T.
So, everybody is different. Which is why I think it is fair to at least mention the consequences of procedures we advocate here. And I advocate them too, so I am in completely sync with you there

While what you say is correct, there are many reasons you cannot get an OTA on an LG phone...
* My wife can not get an OTA on her completely stock native B&H Photo US998, which has never been bootloader unlocked.. Others with B&H Photo (which is the OFFICIAL carrier unlocked US998) have come here complaining they are stuck on Nougat since 2018.
* Older India H930DS owners can not get an OTA update on their phones. (LG changed the supply chain for the newer India H930DS phones and older ones can no longer receive OTA updates.). These are people who bought India H930DS brand new, when first released in India and LG has abandoned them.
My point is: LG OTA updates are never guaranteed in any way whatsoever.
That does not prevent those people from selling those US998 or H930DS phones, just because it doesn't receive OTA updates. That's not important when selling the phone. It's a used phone, sold as is.
At some point I'm going to sell my wife's phone, and it's going to be sold as genuine carrier unlocked US998 -- and I'm never going to mention I had to MANUALLY update it to Oreo and probably to Pie (when it becomes available and is stable). I'm not going to mention it doesn't get OTA updates.. It's going to be sold as-is.
These H931 people come here looking for solutions because they cannot update their phone. So, I'm not going to talk about potential problems for potential future owners. I'm going to solve the current owner's problem right now. Future owners will probably be glad that it's a carrier unlocked US998.
Same with LS998. They HAVE to convert to another variant -- to not only carrier unlock, but to get updates. I'm NOT going to tell them they can't carrier unlock their phone because of FUTURE owners who may want stock LS998 on Sprint?
I'm not arguing with you, I'm just telling you why I will never ever talk about OTA updates for someone who doesn't own this phone right now.

Well. If aosp rom support night sight and work greate. I will use aosp which stable. My v30 on havoc now. But too lazy to back stock rom
And i try to add my device to dualbootpatcher to use dual boot. My v30 is v300k. And dualboot already add ls998 but not working. Flash havoc multiboot when i boot it just reboot to recovery
Havoc is all the way good for me, no problems so far, just waiting on the update build,and like I said before if we can get Ground Zero ROMs || Validus - Tesla - Tipsy, that's when I'm leaving my havoc rom

Yeah, I'm a little confused too. What EXACTLY is the question? What if I like US998 or AS998 stock ROM more? Why are they not listed? Where's LS998? Where's VS996?
To bootloader unlock, TWRP installation, and root, ALL the North American variants (EXCEPT for the T-mobile H932) have to at least temporarily convert to US998 or already be a US998 for fastboot flash commands. Afterwards users can flash what they want -- including TWRP flashable zip files to convert back to former model (H931, VS996, H933, AS998) if they desire to regain carrier-specific options like VoLTE/Wi-Fi calling. (Depends on the carrier if they limit those to their branded models.) Or users can go flash custom ROMs. But many STAY on US998 as it is carrier unlocked and devoid of most bloatware. Even when flashing a custom ROM, they are most often flashing FROM US998 stock rooted firmware. So, very strange it's not listed whatsoever.
H930 is Europe open market carrier unlocked.
H931 is AT&T, but carrier locked to AT&T. Only AT&T customers want that.
H932 is T-mobile but has different RSA encryption from other North American carriers.
H933 is the Canada model, for all Canadian carriers -- but it is carrier unlocked.
US998 is the official open market North American carrier unlocked model -- while also being sold by U.S. Cellular as their V30. V30S is also a US998 variant -- US998R.
Of ALL the North American variants, the US998 is the ONLY one with fastboot flash commands.
AS998 is the "regional carrier" version of the US998, but it doesn't have fastboot flash commands.
LS998 is Sprint's carrier locked V30/V30+.
VS996 is Verizon's V30, and is carrier unlocked.
Then there's H930DS (middle East/Africa/Asia) -- which is the dual SIM V30+, as well as the H930D (Middle East) -- which is the dual SIM version of the V30.
There's also three Korean carrier variants, plus a somewhat strange Japanese V30+.
Right now most custom ROMs are compatible with MOST of the the V30 series. However, H931/H933 has issues booting Oreo custom ROMs. H932 has different RSA encryption, so needs a separate ROM version. The goal would be to UNIFY all the variants so all ROMs would be compatible with ALL variants.
I would be happy with anything that boots on h931.

Yeah, I'm a little confused too. What EXACTLY is the question? What if I like US998 or AS998 stock ROM more? Why are they not listed? Where's LS998? Where's VS996?
To bootloader unlock, TWRP installation, and root, ALL the North American variants (EXCEPT for the T-mobile H932) have to at least temporarily convert to US998 or already be a US998 for fastboot flash commands. Afterwards users can flash what they want -- including TWRP flashable zip files to convert back to former model (H931, VS996, H933, AS998) if they desire to regain carrier-specific options like VoLTE/Wi-Fi calling. (Depends on the carrier if they limit those to their branded models.) Or users can go flash custom ROMs. But many STAY on US998 as it is carrier unlocked and devoid of most bloatware. Even when flashing a custom ROM, they are most often flashing FROM US998 stock rooted firmware. So, very strange it's not listed whatsoever.
H930 is Europe open market carrier unlocked.
H931 is AT&T, but carrier locked to AT&T. Only AT&T customers want that.
H932 is T-mobile but has different RSA encryption from other North American carriers.
H933 is the Canada model, for all Canadian carriers -- but it is carrier unlocked.
US998 is the official open market North American carrier unlocked model -- while also being sold by U.S. Cellular as their V30. V30S is also a US998 variant -- US998R.
Of ALL the North American variants, the US998 is the ONLY one with fastboot flash commands.
AS998 is the "regional carrier" version of the US998, but it doesn't have fastboot flash commands.
LS998 is Sprint's carrier locked V30/V30+.
VS996 is Verizon's V30, and is carrier unlocked.
Then there's H930DS (middle East/Africa/Asia) -- which is the dual SIM V30+, as well as the H930D (Middle East) -- which is the dual SIM version of the V30.
There's also three Korean carrier variants, plus a somewhat strange Japanese V30+.
Right now most custom ROMs are compatible with MOST of the the V30 series. However, H931/H933 has issues booting Oreo custom ROMs. H932 has different RSA encryption, so needs a separate ROM version. The goal would be to UNIFY all the variants so all ROMs would be compatible with ALL variants.

In our Kernel there need to add us998 or us996 defconfig.
So yeah in coming up days, I will build for models of lg v30.
I mean h930, h931, h932, h933, us998 or something like this. All models..

H930 (and D/DS), US998, LS998, VS996, and 2 of the 3 Korean models work fine with the H930 build.
H931 and H933 can boot us998 stock rom, but even with using full us998 blobs + kernel config, it doesnt work (i think @me2151 also tried H931 blobs?)... and theres 1 case of a H933 which can boot all AOSP ROMs... so it has to be something else (maybe certain combination of bootloader + modem... who knows)
And H932 needs their own firmware files, but that works already.
I would be happy with anything that actually works on a 933 that isn't just a modified stock firmware with root and twrp ability.

I have the US998 model, am I supposed to flash H930 ROMs or...?

Hi all, I recently just bought a V30 so I'm all very new to this. I have the US998 model and from what I've gathered so far in this forum is that the US998 model seems to play a very significant role here. Seems like owners of H931/H933 models have to convert their devices into the US998 model in order to install custom Oreo ROMs. But having said that, I haven't seen any ROMs with links to a US998 version, just the H930 and H932. I'm sort of confused, so does that mean owners of the US998 model can flash any ROM version they want?

TLDR:
ALL AOSP/Lineage ROMs (unless specifically H932-only) are compatible with ALL V30/V30+/V30S.
Complete answer:
You've asked a complicated question.
* For the discussion below we are mostly talking about North America variants only.
* Some of this below does not apply to H930/H930DS/H930D/H930G (the 930's).
* Some of this below is also not just to answer this question but for other people who want to buy this fantastic phone.
1) For any V30/V30+/V30S, you have to have fastboot flash commands and have a specific date range of stock Oreo firmware to use the WTF exploit to unlock the bootloader and root. (This does not apply to the T-mobile H932. It has its own root method, has different RSA encryption and is an island to itself. My opinion is to stay away from H932, unless you are a T-mobile customer and specifically want H932 for the T-mobile LTE band 71. I welcome all H932 development, of course and am thankful we finally have root, etc for it. But no need to go out and buy it if you're not a T-mobile customer who wants LTE band 71. Other T-mobile customers have US998 -- original or converted from like LS998 -- and use it on T-mobile.)
Of the North American variants, only the US998 has fastboot flash commands AND has firmware which is totally compatible with all other North America variants, EXCEPT for H932. So, you at least temporarily convert to US998 to unlock bootloader, root. You can stay on US998 if you like, or you can flash back to another North America variant firmware at that point and still retain unlocked bootloader and TWRP (with ability to root). US998 is the official carrier unlocked North American variant, so works with most North American carries. However, some carriers only give some service options on their own firmware; Wi-Fi calling, etc. Your choice whether to stay on US998 firmware or flash to another carrier firmware. I'm on AT&T, but I am still running US998 rooted stock firmware.
2) Once bootloader unlocked and rooted, you can also install custom AOSP ROMs -- but some are easier than others. Former VS998, LS9998, AS998 and original US998 have no problems. AT&T H931 and Canada H933 have issues getting ASOP ROMs to boot up; however there's a complicated workaround was developed where you re-flash different firmware a few times for it to work. You can now run AOSP ROMs on H931/H933, but unless you already have those, there's no reason to specifically buy them if your desire is to run AOSP ROMs. T-mobile H932 has different RSA encryption and needs separate ROMs for that model.
3) The first dev to make several AOSP/Lineage ROMs registered his H930 on AFH server website (which a lot of XDA devs use, and which I use as they give free server space for development), and now AFH thinks ALL V30 are "H930". Even VS996, H933, US998 V30 KDZ which I upload to H930 are categorized by AFH as "H930" when it's not. Confuses people when they click on a link, goes to AFH website and says "H930". ALL AOSP/Lineage ROMs (unless specifically H932-only) are compatible with ALL V30/V30+/V30S.
4) For North American variants, you cannot cross flash H930 or H930DS full stock firmware "ROMs". Stock firmware ROMs are just stock KDZ in TWRP-flashable format. Do NOT try to flash a North American variant to a stock firmware H930/H930DS ROM. You can only flash other North American stock firmware (except for H932) and AOSP/Lineage ROMs. The ONE exception to that is the Boombox ROM -- which is BASED on H930 stock firmware, but IS compatible with all V30/V30+/V30S (except for T-mobile H932).
CONCLUSION
Anyway, that's why you see "H930" AOSP ROMS (they are not really just for H930) as well as H932 ROMs (and they ARE only for H932). The best North America variant phones to buy for AOSP/Lineage ROMS are LS998, VS996, AS998, and original US998. H931 and H933 can flash AOSP/Lineage ROMs but after bootloader unlock and root, you have to then go through another flashing procedure to make it work. T-mobile H932 has different RSA encryption and devs have to release separate ROMs for them.
After you bootloader unlock and root, I suggest trying out rooted stock firmware for awhile. Everything works, and on US998 20F we even now have DTS 3D stereo. There are Magisk mods you can flash which give even more capabilities. The only reason I suggest that is because it helps to have a baseline comparison. Then try the AOSP/Linage ROMs. That way if something doesn't work right, you know whether it's the ROM or the phone.

Hello there i have rooted my us998 and unlocked the bootloader, i am able to flash custom roms in TWRP but they never seem to boot pass the boot animation screen. I have tried LOS16, Pixel experience and DOT OS, they all cant seem to boot pass that screen, so i am certain its not the ROMs (i downloaded the ROMS for h930).
Any help will be appreciated

Then you've read Root Sticky Guide part about custom ROMs? It's linked in the WTF INSTRUCTIONS. (See attached screenshot.)
See post #2 of that thread: https://forum.xda-developers.com/lg-v30/how-to/root-v30-t3927154
What US998 firmware are you on? For LOS-16 PIE ROMS, your need to update to most recent Oreo. Or it won't boot/work right.
Was your phone always USS98 or is it former H931/H933? If you read the guide, you know why I'm asking. There's more stuff you would need to do. Or it won't boot.

Yes i followed that guide word for word, and then updated to the latest rooted oreo firmware which is 20h after unlocking bootloader, by flashing from 20e to 20h back to back and then flashed magisk aftewards just as the guide said.
I honestly can't tell if this has always been a US998 model but then looking up the IMEI online shows its a V30 instead of a V30+

Good that you updated to the latest Oreo.
Does your V30 have 128GB of memory or 64GB of internal memory? IF 128GB of internal memory then it's a V30+. It never could have been an AT&T H931 or Canada H933 as they don't natively have the 30+. It could have been a Sprint LS998 V30+ at one point in time, but there's no issues with former LS998 running custom roms.
It's just the we get people in here who go through the bootloader unlock -- but don't bother update to latest Oreo or don't read the part about h931 and h933, and then wonder why they can't boot to custom ROMs. I apologize, I thought you were one of those people.

LS998 or US998

I found this on ebay: https://www.ebay.com/itm/LG-V30-US9...D4AAOSwqj9beX9a:sc:USPSFirstClass!95132!US!-1
I was wondering if this was an actual US998 or a flashed LS998 because some of the feedback claims that this is a LS998. I see 1,800 units were sold so I'm hoping there's atleast one person on this forum who also bought from this seller. Also, I am on T-mobile, so I was wondering how it would affect the functionality of the phone if it were a LS998.

Doesn't matter. I've had both native US998 V30+ and converted US998 V30+ (former LS998)
Once converted, its fully US998. For T-Mobile or AT&T it will work. However, for Verizon, you would need an already-activated SIM card or a very helpful rep willing to break the rules.
I've bought from that seller several times. My brother-in-law, sister, couple of friends are all using former LS998 converted to US998 from that specific seller.

Hi, I just bought a used V30+ and it currently at android 7 Nougat (US99801c). Interestingly, when I tried to upgrade to Android 8 Oreo, the LGUP regconized it as LS998,which I found out later was a Sprint version, and said that my KDZ file was invalid. I'm so confused. Which firmware should I choose to upgrade ? Please help me

1) you already have US998. Or you say you do... Go into Download mode manually before opening Dev Patched LGUP.
2) if you want to flash US998 Nougat again, see Frankenstein instructions. All the firmware links you need are there. It's how we convert LS998 to US998.

1) you already have US998. Or you say you do... Go into Download mode manually before opening Dev Patched LGUP.
2) if you want to flash US998 Nougat again, see Frankenstein instructions. All the firmware links you need are there. It's how we convert LS998 to US998.

So even if my V30+ US998 is on Android Pie, it can be downgraded with the methods listed above. Correct? I rarely see Pie mentioned >_< Was reading Pie messes something up but that was from a while ago and am just wanting to make sure!

Pie makes changes. People have found charging is slower, and many people complain Wi-Fi signal is weaker. Your mileage may vary. Yet you NEED stock LG Pie as a base to install/run the newer LOS-17 "Android 10" custom ROMs. For people who decide to go back to stock rooted firmware, perhaps with some Magisk mods -- instead of running full custom ROM -- they often make the decision to go back to last stable Oreo.
I have instructions in every Pie KDZ thread how to use Dev Patched LGUP to downgrade back to Oreo. The "Pie problem" you are referring to is many people then have to use permissive kernel for camera/flashlight to work when downgrading, since Pie made changes. Also some other sensors may not work.
If you are down converting back to Oreo because you don't like Pie the best way is to first downgrade to Nougat via Partition DL, then update back to Oreo. This seems to erase the stock Pie effect. Even better (for North American variants, EXCEPT for T-mobile H932!) first flash Canada H933 Nougat via Partition DL mode -- as it has different partition structure (like a sandblaster) -- then go back to US998 Nougat, then US998 Oreo.
For the H930 variants, you shouldn't cross flash to North American variants. Just Partition DL to Nougat H930 and then upgrade back to Oreo.

Thank you! My entire objective is to install Lineage along with Magisk to this phone. So when you say stock LG pie, do you mean any update/version of Pie that comes on the phone when I receive it? Or do I need to specifically have a certain version of Pie? Like if it's on an updated version pushed out OTA for this month vs last month for example. The phone I'm getting is a V30+ US998.

Right now, US998 has only had one Pie KDZ release.
When you get your US998 V30+ it will probably come with Nougat or Oreo and you will have to manually update it. Being totally honest, it will probably be an already-converted LS998 V30+ to US998 V30+. Nothing wrong with that, I've bought several -- my sister and two brothers-in-law use those... But on those, you will never get "OTA". You have to manually update, either via KDZ or TWRP-flashable zip.
If it already has Pie, you will still have to temporarily downgrade to early Oreo to unlock bootloader and root. Then you would update to more current firmware.

Thank you. I was just making sure because I know when I used to root phones back then, security patches and such would sometimes render certain methods unusable. I read that thread but didn't see any mention (probably because it has no issues) of security patches messing with rooting? So that's all I'm making sure of.

All my Guides are current, if that's what you are asking. Especially the sticky " Root Your V39!" thread, the WTF INSTRUCTIONS, all my Oreo and Pie KDZ threads, and Frankenstein instructions thread.

I found this on ebay: https://www.ebay.com/itm/LG-V30-US9...D4AAOSwqj9beX9a:sc:USPSFirstClass!95132!US!-1
I was wondering if this was an actual US998 or a flashed LS998 because some of the feedback claims that this is a LS998. I see 1,800 units were sold so I'm hoping there's atleast one person on this forum who also bought from this seller. Also, I am on T-mobile, so I was wondering how it would affect the functionality of the phone if it were a LS998.

Doesn't matter. I've had both native US998 V30+ and converted US998 V30+ (former LS998)
Once converted, its fully US998. For T-Mobile or AT&T it will work. However, for Verizon, you would need an already-activated SIM card or a very helpful rep willing to break the rules.
I've bought from that seller several times. My brother-in-law, sister, couple of friends are all using former LS998 converted to US998 from that specific seller.

Greets to both of you. I know the above quoted posts are several months old, but I'm kinda frustrated over finding reliable phone sellers on eBay and want to ask, can either of you tell me the name of the seller you were talking about here? I've had to return three phones because of various weirdnesses in phones received (ilke one in Danish and another in Chinese) and then it took way too long to get refunded. I could really use a good recommendation. I've got a list of several LG V30s for sale (and half of them are LS998) but hesitant to buy again because of the bad experiences. Message me if preferred, if you can help at all. TIA!

The name of the seller was yywireless. The phone was mostly fine except for a one scratch on the back, a few chips on the side, and the charging port looks like someone missed a lot. Yywireless seems to have raised the prices though.

Thanks! This seller has a loooong list of phones for sale and I don't know yet if he has what I want. If nothing else I'll catalog the name for future reference. The biggest thing is just knowing whether an eBay seller is reliable as to merchandise or not. As for prices, I would definitely pay more to a dependable/honest seller. Thanks again, especially for responding so quickly!

I bought several LS998 V30+ from him. Some were already converted to US998.
