Chazz,
I'm not sure what the difference is or what my options are at this point.
I picked up a LG V30+, which I thought was a US998 or at least that's what it says on my phone (Hardware Info). But when I ran the iemi # it comes back as an LS998.
Honestly don't know what the difference is and wouldn't care except for the fact that I can't send SMS text msgs. Seems like everything works even receiving SMS msg's just can't send. Oh and it turns out I can't see/view the SMSC #, which I guess is a big deal in regards to sending SMS msg's.
So I've been browsing through this site and you seem to be well versed and would like your opinion/advise if I may.
Q1) Will updating the firmware help?
> Says I'm @ Rev 1.0
Q2) Will updating the software help?
> says I'm at US99810d and Android Ver 7.1.2
Any suggestions/thoughts would be greatly appreciated.
Thanks,
Dirty D.

GENERAL INFO
Yeah, most new and "mint" (like new) US998 V30+ on the market right now (eBay, even Wal-mart) are former LS998 which have been converted to US998 by 3rd party wholesalers trying to offload excess LS998 V30+ stock. Basically like our Frankenstein but probably done though Octopus box or some mass version of that.

I've noticed they often will convert to US998 but leave on Nougat for some reason. Maybe their Octopus box can't do Oreo for some reason? To me, that's a half-finished conversion! When I do it, I go all the way to Oreo!
Sometimes they will actually claim "US998" in the listing -- while other times they will say "unlocked V30+" but then list the US998 bands (which are different from the Sprint LS998 bands), so you assume it's a US998. Neither is technically incorrect, nor lying. It IS now a US998, and it does now have US998 bands... The BEST way I have seen is where they claim "UNLOCKED LS998" -- and when you get it, it's of course converted to US998, as that's the only way to unlock an LS998.
Caveats with former LS998 converted to US998:
If you use Verizon you would run into issues ACTIVATING a new SIM card with a former Sprint phone. You would need an already-activated Verizon SIM card. That's the only quibble I have with the converted LS998, where the origin is not fully disclosed. It doesn't bother me as I use Prepaid AT&T, but I have to warn others.
Sprint customers can't use it on Sprint, as it's no longer really an LS998. Sprint won't allow US998 (even former LS998) on their network. But advertising an "unlocked" LS998 might be attractive to a Sprint user who is thinking of switching to another carrier in the future or to buy a phone that can easily be re-sold. They should be told upfront it's a FORMER Sprint LS998.
None of the sellers are lying; it's just a hard situation to describe if you're not familiar with the V30.
Recently in December, I wanted a new (original) US998 V30+ with warranty as a backup, as I had given away all my converted LS998 V30+ > US998 V30+. My wife and I have original US998 V30/V30+, but I alway like having a new backup in a box in case of emergency. So, I specifically bought NEW US998 V30+ from online Wal-mart. Or thought I did! When I picked it up at local Wal-mart I found it's new V30+ all right -- but converted from LS998.... I kept it anyway, as I know it will work fine. But this time I was specifically wanting an "original" US998, even though I had bought converted ones before and had converted two myself.
Anyway, the point to all this is yes, you have a former LS998 converted to US998. So, do several of my friends and my wife used one for awhile. They all work fine on AT&T network. Cricket runs on AT&T network, as it's an AT&T-owned MNVO.

SOLUTION #1
What is possibly the issue is your Cricket APN. Go to your mobile settings and check your APN against this:
https://apn-settings.com/us/cricket-wireless-apn-settings/
You are still on Nougat, so you should be able to edit your APN settings. On Oreo that capability is locked out, but there are workarounds on Oreo and with root you can still edit APN on Oreo, I believe.
SOLUTION #2
Another option you can try is Master Reset. Sort of like a factory reset but more powerful.
With your device powered off, press and hold the Power button and Volume Down buttons simultaneously for a few seconds.
When the LG logo appears, quickly release and then re-hold the Power button while keep holding the Volume Down button.
Let go of the buttons when the onscreen menu appears.
When you see the option to Delete all user data (including LG and carrier apps) and reset all settings message prompt, press the Volume Down button to highlight Yes.
Then press the Power button to reset the device.
Wait until the reset is complete then reboot your device. If it’s able to boot up successfully, proceed with the initial setup.
SOLUTION #3
As far as the SMSC #, not sure why you can't view it, but the US998 (which you have now) has Hidden Menu which lets you delve deep into various settings. BE VERY CAREFUL in the Hidden Menu. You can mess up stuff, especially if you try to enable additional LTE bands. Don't do that. In the US998 that option doesn't really enable additional LTE bands, but instead locks you on ONE band (which may or may not work).
I've never had to view SMSC #. I stick in my SIM card and the phone works -- even former LS998 converted to US998. So, I'm not sure that's your issue. More likely the APN settings?
SOLUTION #4
Next, you are on very old version of Android. Nougat. At some point, you do need to update to Oreo as it brings lots of fixes and more features.
This thread below is where the stock KDZ are posted. You can use LGUP to update to newer firmware.
https://forum.xda-developers.com/lg-v30/development/us998-lg-v30-us998-us99820a040330-kdz-t3786337
The other reason I am mentioning this is because instead of "upgrade", you can use an option called "refurbish". Refurbish re-builds EVERYTHING while also updating the firmware. It's possible whoever converted your LS998 to US998 botched something, which is why your SMS doesn't work. Using this refurbish option will lay the foundation again, totally rebuilding your firmware.
After you use that "refurbish" option, then in the future just choose "upgrade".

Good luck!
Tonight I will edit the post above to clarify and organize better. I offered four different solutions, but it's not as coherent as it could be.
@ChazzMatt you are very helpful and I think we all greatful to have you in v30 community. You're the best bro! ??

Okay so heres what/where im at.
1) I was able to view and edit the smsc # when the sim was in my old LG device. So i did so and then moved it to my new LG (V30+)
2) Checked & edited the APN
3) Changed the network node from Global to LTE/GSM/UMTS
4) Downloaded LGUP & upgraded
5) Nothing changed on the hardware side - still @ Rev 1.0 but on the software side i'm now at US99820b and Andriod Ver 8.0.0. Its to late to test tonight but tomorrow i'll attempt to send SMS & MMS messages.

Good on APN and the LTE/GSM/UMTS choice.
You only updated to US998 20B (for now) because you intend to unlock the bootloader and root?

So I'm not sure of the need or benefit of upgrading from US998 20B to whatever the latest is (appears to be 20G), but should I get the courage to do so, what would the process be?
Would it be as simple as plugging in the phone to the computer and then launch LGUP, selecting upgrade and the 20g kdz? If so I'd be more inclined to do so if their are substantial benefits for doing so.

Yes, it's almost that easy. However, since there's such a large range of changes (especially to audio framework) form 20B to 20G, best to do it in stages. "upgrade" to 20E, reboot, let it settle a few minutes. "Upgrade" to 20F, reboot, let it settle, same with 20G, done.
I wasn't sure exactly what LGUP method you used to get to 20B from Nougat -- whether "upgrade", DL Partition or "refurbish". If the latter two you could have gone straight from Nougat to 20G. But now that you are on 20B, and you want to use "upgrade" (to keep your settings and data), do in those stages.
Since 20B, camera is improved, front and rear. DTS audio framework is introduced. While you still need root to fully enable it, hopefully that will be fixed by LG in upcoming update. Other fixes. Here's the changelog for US998 20F alone.
change log:
- DTS: X 3D stereo effect function has been added.
- New Always On Display options
- Selfie camera portrait mode
- Improved accessibility.
- Improved keyboard performance
- Improved the delay of keyboard input when installing multiple market apps at once.
- Photo display error in some apps since Google's latest security patch has been improved.
- Improved to keep app aspect ratio settings after app updates.
- Improved the phenomenon that fine lines are displayed on some screens when power saving mode is executed.
- Google Security Update has enhanced your phone's security.
Most of the list is found here in the link below -- plus the AOD and selfie camera portrait feature are from public reports. The AOD I verified myself, but the selfie thing seems to be subtle.
But there were other changes between 20B and 20F, and maybe more changes with 20G.

Bought unlocked US998 V30+, but it's former LS998 -- HOW TO UPDATE?
I'm adding onto this already-created post as it's still relevant. The person below also bought a US998 V30+ and found it's former LS998 V30+ converted to US998, but is still on older US998 Nougat firmware. The dealer/wholesaler probably did via Octopus box or something similar, while we use Frankenstein conversion via Dev Patched LGUP. But we always "finish" the process by then updating to Oreo. So, it's basically an "unfinished" Frankenstein conversion.
They don't have the SMS issue the first person had in this thread, but it's still same underlying issue. LS998 V30+, now on Nougat US998 and they want to update to current Oreo firmware...
Hi ChazzMatt,
I have a question. I am hoping you are willing to help me.
I have an LG V30+ unlocked mobile phone. It says US998 but I just found out that it is actually LS998 (I typed in the IMEI into this website to check what it truly was and it came back as LS998).
The vendor that sold it to me changed the firmware to US998 and I guess removed all the Sprint bloatware or whatever from the phone.
All is totally fine – the phone works great – no issues – I love it and for the low price I got it for it is fine…Except, because of the above, I do not receive any OTA updates.
See attached screenshots of my phone, it is out of date in terms of software and OS and from what I learned from online posts I will never receive any OTA updates.
Is this a problem? Should I update it manually? Can I?
Thank you for your help in advance.

chazzmatt said:
Yes, most US998 V30+ nowadays being sold are already-converted LS998 V30+. You can update to most recent US998 Oreo KDZ via our Dev Patched LGUP.
Later tonight I'll answer more fully.
Click to expand...
Click to collapse
Yes, the only way to carrier unlock a Sprint LS998 V30+ is to convert it to a North American V30/V30+ carrier unlocked version, using a process which we call Frankenstein. The US998 is the most popular firmware to convert LS998 to, as besides being carrier unlocked is also the only North American V30-series variant with fastboot flash commands (which are necessary if you ever want to unlock bootloader, install TWRP custom recovery and root). The remainder of this answer is on the assumption you do NOT wish to root at this time, but merely wish to update to most current US998 V30/V30+/V30S firmware.
SOLUTION
You can go to the US998 KDZ thread and use Dev Patched LGUP to update to US998 20G KDZ (most current US998 firmware at the moment). Dev Patch LGUP is attached to post #1 of that thread, and there are instructions on how to install LGUP, with screenshots on how to use it.
However, in this instance I would recommend using Dev Patched LGUP in "Refurbish" or "Partition DL" (choosing all partitions) mode -- which while it will wipe out your data, will probably present the least problems. There are a lot of audio framework changes with most recent US998 firmware (especially with 20F and 20G) and if you use "Update" mode (instead of "Refurbish" or "Partition DL") you would have to update in stages to 20E, then 20F, then 20G. Best to do it in one step, with "Refurbish" or "Partition DL".
In the future, with other KDZ you would merely use "Update" mode, which WILL keep all your data. It's like receiving OTA updates, but you would be flashing it manually.
MORE INFORMATION
Just for more information (if you are interested) you can also read this Frankenstein Instructions post, on how to convert from LS998 to US998 Oreo -- but several steps have already been done for you. You are already on US998 Nougat. The only step left is to update to US998 Oreo. In that post, you would be on Step #4. Ignore that it says to use "Update" mode. In this instance, I think you should use Refurbish or Partition DL mode. You can use "Update" in the future.
Hope this helps.
Thanks for the great advises Chazz. I was looking for a phone for my dad and your posts made me decided to get the LG V30 for him. I'm still waiting for the phone to come but I'm pretty sure that I got one of these converted ones. I've been reading your posts about converting, rooting, enable DTS. From what I understand, I will need to:
1/ Start at step #4 in the Frankenstein instruction (using REFURBISHED and 20b to obtain unlock bootloader) if my phone already has Nougat.
2/ Upgrade to the latest Oreo 20g
3/ Follow this post to root https://forum.xda-developers.com/lg-v30/help/unlocking-rooting-twrp-magisk-step-step-t3745006
4/ Follow this post to Enable DTS https://forum.xda-developers.com/lg-v30/how-to/enable-dts-3d-stereo-lg-v30-variants-t3887139
5/ Enjoy it.
Is it in the right order or did I mess up between step 2 and 3? Is there any root level adblock? Thanks. I'm using the s9+ but I'm really excited about the V30.

#3 is incorrect. Outdated instructions with old TWRP. Those Instructions were for official bootloader unlock code from LG, which we don't need. We no longer need LG permission to root our phones, plus only a few phones were even eligible under that program. A converted LS998 would not be, nor even most US998.
You want the WTF Instructions. You would use this to unlock bootloader, install TWRP custom recovery and root.
You would merely update from US998 Nougat to US998 20B, install TWRP, and follow the instructions to finish rooting.
After bootloader unlock, TWRP and root on 20B, I would then update to TWRP-flashable zip US998 20G in stages. 20E, 20F, then 20G due to the huge audio changes. (The alternative to this would be to refurbish to 20G, but then you would have to reinstall TWRP and re-root. Let's not do that.)
@JohnFawkes actually has DTS enabled on US998 20F and US998 20G TWRP-flashable zips, through build prop edits -- but you would still need to install the DTS Equalizer.
You have the right idea, just changing the order a bit.

If you don't want to wipe your data, then try Upgrade mode in LGUP.
I was just giving you the answer that will definitely give you best results.
If you use Upgrade mode, you can try to go straight to US998 20G...
but if that gives you audio problems, then go to 20E, then 20F, then 20G in Update mode.
You would download and flash the various US998 Oreo KDZ from this thread with LGUP.

I have a ls998 that was flashed to us998 and the IMEI disappeared
Can someone she'd some light on how to fix this?
Thanks
I have a question for anyone who has converted but not converted back.
Do you think if I converted my H933 to US998 and left it then my phone would have the new DTS features?
I theorize about this because as of right now the H933 is behind the rest of the worlds kdz's and every single custom ROM I flash has random reboot issues.
I'd basically just like to be able to use custom ROMs again so do you think leaving it on US998 and then using a custom ROM will still leave the DTS features etc? ( That I believe have been causing my reboots )
Thanks for anyone who reads and responds.

Thanks! Ultimately my carrier only allows 3G data so for people with ChatR or Freedom I don't think changing back to canadian firm has many advantages. (Yet)
While it's neat we have figured it out to a settle point. (20i kdz) I'd love to try multiple things again.
Appreciate your response and looking forward to when you guys post when H933 does actually get DTS.

To clarify, (I know you know this, but for others....) for DTS you will need US998 AFTER 20E -- like 20F, 20G, 20H. To flash in TWRP, @JohnFawkes suggests dirty flashing 20E, 20F, 20G, 20H all back-to-back in TWRP queue, then followed by Magisk. I would use Magisk 18.1. I've seen reports of 19.1 not working well with some of these TWRP-flashable zips. At least that's where the evidence points...
Once on US998 20H, then you can try updating the Magisk to 19.1...
Or you can do what others have done, flash US998 20H KDZ, reinstall TWRP, flash the no encryption, no root check files and Magisk. Your bootloader is already unlocked, so you can do that. Clean install.
However, at that point you should flash the Anxious module or do the build prop changes to get the DTS, etc. See this post:

I want to know if frankensteining a carrier unlocked us998 to vs99(Verizon version) is just a quick one step process to latest Pie, or do I need to install all updates one by one? The us998 is activated on Verizon and has Android 7.0 on it. Thanks.

One of the trouble shooting tips in the Frankenstein post is to reinstall drivers, another is to try a different computer.
The dll error ALWAYS means either you didn't install the correct version of the Dev Patched LGUP or not using it correctly (like not launching from desktop shortcut, but instead trying to use the folder .exe file). If you are sure you have installed correct, have installed all the correct drivers, then try a different computer.
Thanks for reply. I've tried all steps from the post. Reinstalled, deleted, restarted. Only thing I haven't done is try a different computer. I get "LGUP can't load the model[c:\Program Files\LG Electronics\LGUP\model\com" error. Am i missing a file?
I noticed that the program also installs onto my C:. I also have to delete c:\LG Electronics folder. Is this normal? I've downloaded LGUP Dual from both links in the post. I guess i'll try a different PC. Thanks for your help.
I got it to recognize! Had to try on another computer but now it works. One more question though. Do I need to make a backup? If for some unknown reason I need to get back to the original software, how do I go about doing that? I have us998 with us99810b installed with Android 7.1.2. Thanks again.

You would simply do the reverse. You would flash your phone back to US998 KDZ. However, US998 10b was very early Nougat. If you ever go back to US998, like to sell the phone or something, I would at least flash to newer US998 firmware -- like 20h (last Oreo).

Actually it's VS996, for the Verizon V30, not VS9998.
So you're on US998 Nougat?
Technically for Frankenstein, using Dev Patched LGUP you should Partition DL to VS996 Nougat, use Master Reset, then Refurbish to VS996 Pie.
However, US998 and VS996 have a level of compatibility the others don't enjoy. I think you can Partition DL straight to VS996 Pie, followed by Master Reset.
If you're not sure what Master Reset is (sequence of button), see the Frankenstein instructions.

Thanks for the reply. Do you recommend going straight to Pie? If its more reliable in steps ex. Nougat, Oreo, Pie, then ill do it. I was just wondering if jumping straight to Pie would cause issues.

No, won't cause issues if you're using the KDZ.

You're not Bootloader Unlocked and rooted, are you? You don't care about that? It's fine if you don't. Neither is my wife's, sister's nor brother-in-law's V30/V30+.
BUT if that is something you would want, no, you can't go straight to VS996 Pie until you do some other stuff.
But if you just want Verizon firmware, then you should be able to jump straight to VS996 Pie from US998 Nougat, going by what other Verizon users have done. Use Dev Patched LGUP in Partition DL mode, with all Partitions. Then Master Reset.
If for some reason, doesn't work, then tour would need to flash VS996 Nougat, Master Reset, then VS996 Pie.

I'm wondering the same as charulo316, but my v30+ is already running pie, but for the unlocked and I want to switch to the Verizon one, do I need to downgrade to Oreo and then back the the Verizon pie version??

You are basically asking about Frankenstein, where one North American variant can be fully converted to another (firmware, modem with LTE bands, etc)
Normally, for most North American variants, when flashing KDZ (LG stock firmware image) you actually need to downgrade all the way to Nougat first before upgrading to more current firmware. See Frankenstein instructions.
But US998/VS996 have a very close relationship. If have US998 firmware on the phone, you can go straight to Verizon VS996 Pie firmware using Dev Patched LGUP. For this specific combination you do not need to downgrade first.

Thank you!! I did some more searching around the site late last night and am going to try it tonight. The main reason is because i just switched to Verizon and the WIFI calling option disappeared even though it was "turned" through Verizon. It seems to be that even though I have a carrier unlocked phone, Verizon doesn't see that and will block certain features unless it is a Verizon phone. I have access to the network, but not the wifi calling
So I'm still having issues. I've downloaded and installed drivers and LGUP Dual mode from the link and can't seem to get it to work. I get the phone into download mode and it goes into the firmware upgrade screen but my LGUP doesn't load. I get a "LGUP can't load the model[c:\Program Files\Lg Electronics\LGUP\model\com" error. Any suggestions?
Just trying to install VS996 onto a Verizon enabled us998 so that i can get wifi calling, visual voicemail and video calling to work. Thanks

See the trouble shooting tips in the Frankenstein Instructions. How many of those have you tried?
Sounds like LGUP wasn't installed correctly. It needs to be installed using very specific steps. There are other possible explanations, but this is where I would start.
Uninstall LGUP completely (in Programs & Features control panel), then delete all its remnants and folders and restart Windows (not Shutdown, Restart).
Now download LGUP from the link in one of ChazzMatt's Pie KDZ ROM threads, and install it EXACTLY folding the steps he gives, no shortcuts or deviations.
If it still doesn't work, follow his troubleshooting steps in the same ROM thread.
Edit: Oops, Chazz beat me to it.

My V30 doesn't seem to enjoy being flashed with Android 10, as it bootloops no matter what ROM I decide to use (Lineage, Havoc, Pixel Experience), and now I'm thoroughly stumped on what to do, as I can't find a fix for this issue. My phones bootloader is unlocked via Frankenstein, and I've used the method of flashing over 10d with 30b and having no luck. I've recently come across a post that said to attempt trying 20b to 30b, which I'll try as a last effort to get this working, but I'd still appreciate advice on what to do. Whether it be this last method, a modification of it, or just something else entirely, I'd be forever grateful for the help.
If you need more information, feel free to ask and I'll provide to the best of my ability.

1) You need stock Android 9 (Pie) as a base before flashing any LOS-17 (Android 10) ROMs. But you seem to know that.
There are several methods to update to to Pie US998. See US998 Pie KDZ thread, post #2 and FOUR MORE WORKAROUND in post #6.
2) What variant did you start with? If you have former AT&T H931 or Canada H933, you'll need to do additional prep steps before installing any LOS custom ROMs.
Of course, you've read the V30 custom ROMs FAQ -- before you even unlocked your bootloader -- right? It tells all this and conveys other important information. This FAQ is prominently linked in the WTF instructions, with suggestion to read first, then come come back to finish unlocking bootloader...

Yes, I did read through the FAQ before and after unlocking. My variant is the US998U/V30+, which is why I'm a bit confused. The US998 and US998U are identical, aside from storage capacity, right?
I was following one of the guides you posted that stated:
ChazzMatt said:
So for installing the KDZ, I suggest FIRST downgrading to US998 Nougat 10d via Partition DL mode, Master Reset, then Refurbish to US998 Pie KDZ. Here are the steps...
If you have problems flashing this US998 Pie 30b KDZ, see post #6 for FOUR more workaround methods proven to work for some people.
You should probably use this method (DOWNGRADE to NOUGAT first) even if you have TWRP installed. Then reinstall TWRP again after successfully updating to Pie.
KDZ INSTALLATION INSTRUCTIONS
0) Turn off phone, manually go into Download mode before opening Dev Patched LGUP.
1) Using Dev Patched LGUP from THIS thread, flash US998 10d Nougat KDZ via Dev Patched LGUP using Partition DL mode. Select ALL partitions.
2) Master Reset. This is NOT Factory Reset.
3) Boot up to Welcome screen. Turn off phone, manually go back into Download mode.
4) Flash US998 30b Pie KDZ via Dev Patched LGUP using Refurbish mode.
5) Master Reset. This is NOT Factory Reset.
If you did not unlock your bootloader before doing this, then you bootloader is still locked -- because that's what you want. Finished. Set up your phone.
If you had unlocked bootloader before doing all this, you will still have it. Boot to ADB, and PLEASE follow these instructions for re-install TWRP and root!!

So that's what I had done a few days ago, but that's also when my problems arose. I was on the TWRP flashable kdz of 30b for a month or two now after Frankensteining it, but wanted to try out some 10 ROMS, but attempting to flash those ROMs was when I started having issues. Flashing the stock US998 kdzs didn't cause issues, the 30b zip I had been running daily wasn't weird, and the md5s for all the files downloaded matched what was provided as correct. That's why I'm a bit stumped, since I believe I followed all the guides I've looked at to make things work correctly, but this one part is giving me a hard time.
I will try those other four methods, since I don't believe to have seen them yet. I will provide an edit to this post after trying them, thank you.

If you Frankenstein'ed, I'm asking what your original variant is. Frankenstein is to convert North American variant to another, also called cross flashing.
Whereas " WTF" is bootloader unlock and installing TWRP. Some North American variants have to Frankenstein to US998 for fastboot flash commands. Then they can use WTF INSTRUCTIONS. But Frankenstein itself is not bootloader unlock, TWRP and root. It's just fully converting one variant to another. It ONLY works with the North American variants, except for T-Mobile H932.

OK, so you were on LG US998 30b stock Pie successfully.
Put your IMEI into this database and tell me what it says? Don't post your IMEI here, publicly. Just curious what variant it says you have.
https://www.imeipro.info/
If you have V30+ US998 , then it's either native US998U or was formerly LS998U and converted to US998 by you or previous owner if you bought it used.
Neither AT&T H931 not Canada H933 have a native V30+, but I've seen H933 V30+ which were Frankenstein'ed.

Merely downgrading to earlier firmware is not Frankenstein. Frankenstein is fully converting one variant to another. It takes on those different LTE bands, etc. Cross flashing AT&T H931 to US998 gives it CDMA bands the H931 doesn't have, different LTE bands, fastboot flash commands. Same with Frankenstein'ed H933. See screenshot.
If you already had US998 firmware and your IMEI check says it's a native US998U (V30+), then you didn't Frankenstein to US998. You already had US998 with fastboot flash commands. You just used LGUP to downgrade to early US998 Oreo for WTF bootloader unlock, TWRP installation and root and/or maybe you went to US998 Nougat at one point. But you were already US998. You weren't on LS998, AS998, H933, H931, VS996 firmware, at any point in time.
Why you are bootlooping on LOS-17 Android 10 ROMs, I don't know. You don't have former H931 or H933, and you said you were on US998 30b (Pie) when you tried to flash those ROMs.

The problem with Method #4 is you are willingly converting to Canada H933. While that might get you back to US998 30b, it will then give you more difficulty in flashing LOS ROMs. You have to go through the tedious extra steps of former H931/H933.

That's your decision. It should get you back to 30b. After that, for flashing ROMs, you'll have to follow the other instructions for H933 (since you will have converted to that, then converted back).

LGUP doesn't seem to recognize my phone as a H933 after flashing and rebooting back to download mode, but the phone seems to know it's one when I flash and it says what build it's on and what's being flashed.
EDIT 1: Reinstalling LGUP fixed that particular issue, so I'll have to restart the procedure just so it's as unobstructed as possible.
EDIT 2: Never mind, still the same strange occurrence that happened before. I'll try to move on and see if it'll still work.
Okay so, after a lot of trouble, everything seems to work. I ran Jett's Wifi Backup fix to fix the broken wifi on Havoc, along with the Haumea kernel, and now everything seems stable.
Thank you for your help!!
I guess I just had to keep doing the procedure until it stuck
Hi guys, I'm a bit lost too.
My phone is a V300S that is Frankensteined to US998 with V300S modem, bootloader unlocked and installed TWRP.
However i also faced the problem of installing Android 10 based roms causing bootloops, I've seen on the Custom ROMs page that i needed the lastest stock Pie blobs, which is what i have currently (30b)
Is this variant using a different way for custom ROMs? Or did i do something entirely wrong on Frankensteining?
Edit: silly me recently saw that i need to convert my V300S to H930, not US998... I guess I'll try that first
Update: well everything went south, now i can't go back to US99830b anymore, stuck at V300s Oreo. I guess I'll start everything over again, but if there are things or procedures i needed to know, please, any help will do
Good day everyone, I'm new here so i hope i'm posting this right
This month i got an LG V30 V300S (korean variant), it was supposed to be H930 but they sent me this one instead, it didn't bother me much at first since the phone supports my country's frequency and XDA still supports the korean variant V30s, and I can't return the item too cuz of pandemic.
I came from the LG V20 so I'm quite familiar about cross flashing, but even before that i still did a little reading regarding on unlocking and rooting the phone on the V30 XDA thread (kind of easier than the V20 tbh).
The first thing i did was unlock and root the phone, installed TWRP and installed V300S firmware
(Based from here: https://forum.xda-developers.com/lg-v30/how-to/korean-variant-bootloader-unlock-root-t3804505)
It was ok at first, but now i decided to cross flash to US998 30b (Pie) via TWRP because V300 firmware is full of bloatware , and i stayed there for a few days.
Now i was wondering of installing Custom ROMs on the phone, it was a messy thing for me to understand, but as far as i knew since i want to install Android 10 based roms (Havoc OS), i needed Stock pie blobs.... Unfortunately it didn't work, i ended up in a bootloop, so i went back to US998 30b again.
After a while, i wondered that maybe the whole crossflashing is wrong? So i backed up the phone and flashed an H930 31a instead, but has no signal
Previously i can just easily bring back the modem using backed up V300S modem via LGUP or TWRP, but this time it didn't work, i also picked an older version (H930 30q) to match my phone's modem version, still no avail
And even disregarding the signal, i attempted to flash the custom rom again... Still bootloop
So I gave up at this point, and decided to go back to US998 30b, but this time i can't go back to US998 anymore, it also bootloops
I don't know what i did wrong now, i just followed the same instructions.
V300s > H930 > unlock > TWRP > US998 (TWRP)
Only difference on this one is i no longer flashed V300 kdz cuz i don't have one
So now I'm stuck at V300s_21e_Oreo cuz it's the only ROM that worked
I know I'm doing something wrong here, but due to a lot of procedures i have done I don't know where to start anymore, the phone is fully working with signal right now, but it lags on this ROM, US998 30b was way snappier
Sorry for the long post, I'm just desperate
Any help or suggestions will do.
Update: managed to go back to US998 Stock pie (30b) no idea how, 4G is painfully slow but i guess this will do for now
