LG US998 or LG LS998 - LG V30 Questions & Answers

Greetings Geek’s
I would appreciate someone helping me understand.
I recently acquired an LG V30 + that in the system tells me that it is version US99830b android 9, but at the time of reviewing the IMEI on any website for those purposes it tells me that it is version LG LS998 Sprint.
In the hidden menu * # 546368 * # xxx # tells me that the US998 version is original

Not sure I understand the problem. If it's on US998 firmware, it's a US998 now. Most US998 being sold online are former something else. LS998 is carrier locked to Sprint. Whereas, US998 is carrier unlocked (SIM card unlocked) firmware and has fastboot flash commands. LS998 never got LG stock Android 9/Pie, by the way. So, the only reason you have it is because your LS998 was converted to US998.
That's what Frankenstein thread is all about, to convert other North American variants (Sprint LS998, regional carrier AS998, Verizon VS998, AT&T H931, Canada H933) to US998 firmware -- either temporarily for bootloader unlock or permanently because it's carrier unlocked firmware and designed to work with all North American carriers. For instance, US998 users get T-mobile VoLTE and Wi-Fi calling. If you want carrier-specific firmware back, you can install it via TWRP-flashable zips our Devs have created. But if you are not a Sprint customer, you do not want Sprint firmware.
I own both native Open Market US998 and former LS998 converted to US998.

In terms of performance and functions I have no problem, I just wanted to make sure I was correct, because there are two firmware versions on the network and I would not want a brick to step on papers.
Thanks for your clarification.

What LG V30 I have?

I know this might be the dumbest of questions, but searching the webs gives no straight answer. I have doubts on to which exact model I have. These are the details:
-I bought it apparently refurbished, almost spotless (one little blue pixel in the corner).
-There was a sticky note that said LG ls998 made in Korea.
-However, cpuz says LG us998, joan_nao_us.
-Back says v30+, internal is 128gb.
I just want to be sure before attempting any procedure. Thank you in advance.

You don't say what firmware you have, Oreo or Nougat. Does the firmware in About Phone say US99810D or at least start with US998?
Did you buy it from YYWIRELESS on eBay?
Sounds like you have a former Sprint LS998 V30+ -- which the seller has Frankenstein converted to carrier unlocked US998 V30+. Nothing wrong with that. Carrier unlocked US998 has a lot of advantages over LS998, like fastboot flash commands and it's not locked to Sprint.
Did they flash Oreo or leave it on Nougat? Flashing US998 Nougat is the first step, and for some reason this seller (if you bought it from them) in at least two cases just stops there and doesn't flash Oreo.
Still, they've done the hardest part for you.

Did you check the IMEI number? That should give you the OEM designation for the device.

Firmware says US99820b, Oreo 8.0.0 with security patch level from May 1st. While messing with it, I think I recall reading sprint somethingsomething even though I see no sprint apps anywhere, so you are most likely right. Thus, I need to read about ls998 frankensteined into us998 in order to be aware of whichever procedure not to perform. Any advice?
IMEI shows many possible devices, I can't use it to verify the exact model, but thanks.

Good that if your phone was Frankensteined, they took you all the way to Oreo. Also, good they left you on 20B (Pre-July 2018 firmware), in case you want to bootloader unlock and root.

No, if you have US99820b, for all intents and purposes it's US998. Even in Frankensteined from Sprint LS998, it's now a US998.
We found out the AT&T H931 and Canadian H933 that were Frankensteined -- while they could be bootloader unlocked and rooted, they can run only stock firmware or stock-based ROMs. They can't boot and run AOSP ROMs for some reason. But former LS998 does not have that restriction.
Then I can safely proceed with any and all instructions addressed to US998. Thank you for your time and support. Mods can now close/delete the thread. Best regards!

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.

Can I flash these other us-variants directly with LGUP?

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.

I flashed my H931 to US998 like in the Frankenstein instructions:
https://forum.xda-developers.com/showpost.php?p=76510671&postcount=168
Everything worked perfect!
The US998 seems just right for me - all bands I need and all functions are now working as they should (with the branded H931 AT&T I had wifi-tethering problems)
Thanks for the help!

Hello!
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.

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.

LS998 to US998 Questions?

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.

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.

which room you guys like more​
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.

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+

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.
