I currently have a Sprint LS998 which I've been using for almost a year, with the recent OTA update LTE calling is getting disable which is a real bummer and Sprint's VoLTE isn't available in my area. After looking on the forum pages I found out that it is possible to flash my Sprint LS998 to a US998 but had a couple of questions before I attempted it.
1. Will it work with on TMobile/AT&T/Verizon?
2. If i do decide to flash will I still retain VoLTE, HD Calling, Wifi Calling when switching to a new network?
3. Once I've flashed will I still be able to obtain OTA updates?
Sorry if these are noob questions, I am quite new to this. Thanks.

Yes to most of your questions.
I believe you can get T-Mobile VoLTE converting LS998 to US998 KDZ, just through Frankenstein. I know there's lots of US998 on T-mobile.
I KNOW you can get Verizon VoLTE/WiFi calling by converting LS998 to VS996 with KDZ, via Frankenstein. But you would need already-activated Verizon SIM card.
However, for AT&T features like that, you need bootloader unlock, TWRP and then flash AT&T stock firmware ROM. Which means you would Frankenstein to US998 to get fastboot flash commands. If you were bootloader unlocking and installing TWRP, you could also afterwards flash the latest Verizon stock firmware "ROM" (built from the latest Verizon KDZ), if you didn't want AT&T. However, I recommend AT&T just because I use them.
So, you have options with both stock firmware KDZ or options after bootloader unlock and TWRP -- whatever you prefer.
----
You may not receive OTA after converting from LS998 -- but you don't need it. We have all the latest firmware posted here (in both KDZ and TWRP flashable zip "ROM") in this forum. For reasons unexplained, my wife has not received any OTA for her totally stock US998 since January 2018, but she's still on the latest firmware. I flashed it via LGUP. For myself, I use TWRP-flashable zip (since I'm bootloader unlocked and have TWRP). Easy to flash newer firmware in less than 5 minutes, which is typically released every 2 or 3 months.

Just to confirm in order to get the phone working on AT&T I need to first Frankenstein it to US998, then unlock the bootloader, and finally flash an AT&T stock firmware ROM? From then I should be able to put an AT&T sim card and activate service?

We're getting into a lot of scenarios here. I don't want to tell you wrong, but there's lots of options. For ME, I care about bootloader unlock and root and my answers are going to be skewed that way.
1) If you do NOT want that, just buy an AT&T H931. Done.
2) My phone works on AT&T as US998 -- but I don't have Wi-Fi calling. I have AT&T Prepaid and I don't care.
3) If you buy another North America variant (say fantastic price) that can be Frankensteined, and you want all the options and privileges on AT&T you will need to flash it first to US998 -- bootloader unlock/install TWRP -- and then flash the AT&T zipped firmware file.
The only caveat is most people who do this already have activated AT&T SIM card. US998 and H931 will activate on AT&T just fine. BUT they may balk at "Sprint" LS998 IMEI even though it may have US998 or H931 firmware. Depends on the store you use. There are other North America variants you can buy but for some reason the LS998 V30+ (whether actual or already flashed to US998) is ridiculously inexpensive.
Hello guys, if I bought a Sprint lg v30 with a bad imei, can I Frankenstein to US998 and use it with T mobile and ATT?

Frankensteining doesn't change the IMEI.
Talk about changing the IMEI is not allowed on XDA, as I recall... you may have to look elsewhere.
I'm gonna hijack this thread to ask a couple questions about Frankenstein v30's. I'm a Canadian on Bell and want to pick up a v30. I found a bunch on ebay us998 for a good price, how can I tell if it's been done? Will it really affect me at all if it is? I do travel to the US sometimes does that mean anything for when I try to use it down there?

At worst you would need an already activated SIM card, if it's LS998 to US998. I've owned two and two friends have a couple -- all of us are on AT&T and just put in our SIM cards. A friend just went today with a converted LS998/US998 and AT&T ACTIVATED a new SIM card for her. She called me to tell me of the success. I was a little worried. For her other LS998/US998 phone (a few months ago) it was an already activated SIM card, but this "new" phone (today) was for her sister.
I can't tell you about Canadian carriers' views on that subject.

You would just need to find a carrier who doesn't care it was possibly a Sprint phone but is now a carrier unlocked US998. Shouldn't be an issue unless you are trying to use Verizon or Sprint.

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.

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.
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.

Ahhh okay this all makes sense now
And yeah that's exactly what I'm planning to do, I'll try the stock ROM for a while first.
Thanks so much for the clarification.

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/Lineage 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.
I bought an LG V30, but is the model VS996 and i having issues with the Verizon customization, coz for example i cant enable 4g calling due i dont have Verizon SIM.
Other issue am having is that i cant conect 4g data even when i put the apn, if i switch to 2g and the come back to 4g i can activate 4g data but later the problema comes back, and is very weird and annoying.
I think my problems can be solved if i change my firmware, so i have 2 questions:
Whats the best oficial unlocked firmware (with no phone company) for the lg v30?
And my device is unlocked
If i change the firmware my phone locks again? Coz in the country where i live theres no Verizon so i wont be able to unlock it again.
Thaks if someone responds

You need to convert your Verzion VS996 to "open market" carrier unlocked US998 firmware. US998 is the official carrier unlocked firmware for North America and works well on the (North America) Verizon VS996.
See the Frankenstein thread instructions.
IF you're not a Verizon customer, then yes you do not need or want U.S. carrier Verizon firmware. Instead you need the official carrier unlocked US998 firmware. You can convert the VS996 to US998, which will solve your problems.
After conversion you will have carrier unlocked US998 with these bands:

No he didn't. No one has bricked their phone flashing VS996 to US998. You're probably quoting some person who didn't follow the directions. Even then his phone wasn't bricked he just needed to do a Master Reset, which is the next step after flashing Nougat. Some people don't like to follow directions.
Just read the directions. No need to ask any more questions here. Ask in that thread if you don't understand the instructions. They tell you exactly what to flash. There's only five steps.
Many thousands of people have converted to us998 and no one has bricked their phone, unless it's someone who tried to flash U.S. T-Mobile H932 against all warnings...

Not if you follow the Frankenstein instructions correctly. All North American variants can be converted to all other North American variants -- EXCEPT for T-Mobile H932.
The Frankenstein instructions I wrote are for converting to US998. You are just going the other way. See my post above. And go read the Frankenstein instructions. VERY important you downgrade to Nougat first!

Well, first you only mentioned LTE band 8. And you have US998. So, that's easily solved. Convert to Canada H933.
H933
2G GSM: 850/900/1800/1900
3G UMTS (HSPA): 850/1700/1900/2100

2G GSM: 850/900/1800/1900 MHz
3G UMTS (HSPA):850/900/1900/2100 MHz
4G LTE Bands: 1/2/3/4/5/7/12(17)/13/20/25/66
AMAZINGLY, every North American V30/V30+/V30S can be completely converted to any other -- EXCEPT for T-mobile H932. But this cross flashing/conversion (IF DONE RIGHT!) includes LS998, US998, AS998, Verizon VS996, AT&T H931, Canada H933, Puerto Rico H932PR (NOT to be confused with T-mobile H932!) 7 DIFFERENT North American models you can convert to another and change LTE bands!
HOWEVER, you can NOT cross flash H930 variant modems (H930, H930D, H930DS, H930G) with North America variant modems.
So, you can either have US998 or you can have H933 -- or one of the other North American variants if you flash those KDZ. (AT&T H931 has LTE band 40, but doesn't have LTE band 8.) If you don't have one of the LTE bands, you can drop down to 3G during that time.
Someone else from Indonesia posted few weeks ago, so I understand your situation. As I told him, if he needed an H930DS, he should have bought an H930DS. I'm sorry, I don't have any other answers.

H933 doesn't have fastboot flash commands. That's why in the "WTF Instructions" all North American variants (except for T-Mobile H932) have to temporarily convert to US998 to bootloader unlock phones and install TWRP. Of all the North American variants, only USS98 has fastboot flash commands.
So, they use Frankenstein instructions to convert to US998. If they then want to go back to their previous firmware (while keeping TWRP), they have to use TWRP flashable zip (basically a stock ROM) for thier firmware.
Is that why you're asking about fastboot? To unlock bootloader and install TWRP custom recovery and root?

The same WTF Instructions which tell how to unlock the bootloader also tell how to install TWRP and root.
You had to convert back to US998.
Section 5 was unlocking the bootloader.
Section 6 of WTF Instructions is installing TWRP and root.
So, I'm puzzled. If you indeed unlocked the Bootloader using the WTF INSTRUCTIONS you would have already known that. There's something I'm probably not understanding about your question -- or you haven't actually unlocked the bootloader yet?
Read the Instructions in a web browswer, not an app.
