Dear XDA Forum:
I'm a new member of XDA forum and would like to thank you, everyone, for taking their time on reading this post.
Back to the point. I have with me an LG V30+ (H930DS) from Saudi Arabia.
Here are the specifications list according to the Software Info:
Android Version: 7.1.2
Android security patch level: January 1, 2018
Software Version: V10e-AME-XX
I'm very frustrated with how LG deals with the software updates. I'm using an unlocked variant LG V30+, yet, I still didn't get updates. I wish to use the latest software updates. So, I thought about to convert it to US unlocked variant version, but, I'm struggling with how to do it. I'm still pretty new to dealing with this kind of problems. I hope XDA will provide me the guidelines on this matter.
Thank you!
You can download below kdz file and install for me this is working normal for UAE version V30+.

You have to use the H930 Europe KDZ. KDZ is down om Development with attached LGUP tool to flash.

Dear ChazzMatt:
What is the difference between H930 and H930DS?
Will it affect anything from my network sim?
I'm moving from Saudi Arabia to the Philippines on May 31, 2018. So, I'm wondering if I will be able to use the Philippines sim card if I update it to Oreo?

Flashing H930 Oreo KDZ over H930DS will give you Oreo, but you'll lose 2nd SIM capability. You would have these bands:
If you have"H930" (either actual or converted), you will have these bands:
2G GSM: 900 / 1800 / 1900
3G (HSPA): 850 / 900 / 1900 / 2100
4G LTE: 1/2/3/4/5/8/12/17/20/28/38
You can flash the Hong Kong H930DS Oreo KDZ and still get the same Oreo but retain 2nd SIM capability.

Dear ChazzMatt:
Can you please explain to me what bands are for? Does it play a big role in using my phone with sim cards? If it does, will I still be able to use Data Connectivity, Calls, and Text Messages through sim cards?
Apologize for lack of knowledge regarding technology.

Just to verify, which "Process" I should choose.
REFURBISH, UPGRADE, PHONESETTING, AND FOTA UPGRADE.
I assume its Upgrade?

Yes, upgrade to keep apps and data. Refurbish if you want a clean, fresh start.
I have finished flashing Android Oreo on my phone using the method you provided on another article.
I flashed SEA/ Singapore KDZ on "lg-firmwares". The only downside that happened during the process was, it required me to reformat my phone to gain access to my phone. I lost all of my graduation photos... Darn it.
Anyways, so far with a 6 hours experience on Android Oreo. I enjoyed the new features. I definitely see an improvement on phone's and battery performance with more control privilege. I'm still disappointed with the camera even with the AI cam implementation. Somehow fish is detected as a dog... Everything is not perfect anyways in its first development. I'm not expecting too much out of it. But I hope and wish they will improve the camera software, especially HDR mode. In Google Pixel 2 XL, the built in camera software is a beast. They should've copied that xD.
Thank you for providing me enough details to accomplish what I want with my LG v30+. I really appreciate every person who commented in this post. Once again, thank you!
Sorry about creating a thread but wanted to make sure I can flash Sprint LG v30+ to T-Mobile without issue. Tried to read a few threads but from my understanding Oreo had messed things up at one point.
Does it have to be unlocked through Sprint first?
Simple flash T-Mobile or international rom makes it usable?

No, doesn't have to be unlocked through Sprint first. And Oreo didn't mess up anything.
Some of the T-Mobile guys are complaining about T-mobile Oreo. I own five US998 and don't see anything they are complaining about. Must be a T-Mobile H932 issue.
You will convert LS998 V30+ to official carrier unlocked model US998 V30+ with Oreo, and run on T-Mobile. Converting to US998 carrier unlocks the phone and gives it fastboot flash commands.
You can stop there, or you can bootloader unlock, install TWRP and root the phone.
Whatever you do after that (Install ROMs or whatever) is your choice.
You will NOT flash T-Mobile firmware onto the phone or you will brick the phone.
Many T-Mobile users are running rooted US998 (original or converted) on T-Mobile.

My Sprint V30+ is sim unlocked. If I flash it to carrier unlocked phone and toss a TMobile sim in it, will I get access to VoLTE?
Right now when I toss a TMobile sim in it, calls drop to 2G/3G.

If flashed to US998 Oreo you will definitely get T-Mobile Wi-Fi calling.
T-Mobile users can answer specifically about T-Mobile VoLTE on US998.
But since you can temporarily drop down to HSPA for phone calls and still get data, it's not critical. I don't have VoLTE on my AT&T Prepaid plan and I don't care.
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.

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.

All right, buddy. We'll just agree to disagree on that. And that's OK with me. Having seen all the good you do for the V30 community over the last couple years, you're the last person I want to pick a fight with. :good:
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.

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.

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.
