US998 original, TWRP 3.2.3-7-DataImg, bootloader unlocked
Have tried installing both Lineage and LiquidRemix, with no success. Upon reboot, phone bootloops. Easily put it in download mode and start all over again, using factory image (data seems to be getting corrupted).
When in recovery: factory reset, then wipe data, dalvik, cache, and system. Only installing ROM at this time, trying to weed out potential problems.
Tried flashing just no-verity earlier and phone was stuck on splash screen, then.
Any suggestions on this would be appreciated. Not sure where to pull a logcat, even if available, as I am not 100% sure where the problem is originating from.

Did you ever update stock firmware to newest update before trying to flash a custom ROM?

Was rooted, with Magisk, on US99820H, when i did it the 1st time.
Thought there was a chance maybe i had not removed encryption but it seems to be something causing data corruption.

I've no idea if this will or won't help, but have an ls998 converted to us998 which has successfully booted numerous of the custom roms, even from us99820H.
I always remove any accounts on phone, any finger prints unlock, pins, everything. Then do a factory reset. It should be bone stock at that point (for 20H), except of course bl unlocked and twrp installed.
Then, install the rom as you have been. If it doesn't boot, in the various after market rom threads people have discussed fixes they've found. But from what I've read it seems a pretty common problem is the device itself. You say it was an original us998? Was that US Cellular us998? I had one of those, it wouldn't boot an aftermarket rom either.
good luck, Cheers
Did you try flashing the TWRP ready firmware for your phone?
This is what ChazzMatt said: "If you are installing/updating latest US998 firmware for the first time after bootloader unlock/root, you should flash 20e zip (below), then 20f zip, 20g zip, 20h zip back-to-back in TWRP, then flash Magisk. If you go straight to 20h via TWRP-flashable zip from very early Oreo, you will most likely have problems. There were massive changes starting with US998 20f and you need the prior 20e as foundation before going on to 20h. You should also do this if coming from a custom ROM."
So, I am guessing you can flash a custom ROM by just flashing 20e first then the custom ROM after. Instead of flashing a custom ROM from 20h, which is known to cause issues.

IF it's been converted from LS998 you'll get a false result like that. You're sure you have original US998?
US998U just means US998 V30+. U.S. CELLULAR sold them as well as B&H Photo, Best Buy, Amazon...
I know nothing about U.S. Cellular. It's possible they only allow phones they sold, whose IMEI are on their database. I don't know.

TWRP: TWRP-3.2.3-7-default.img
Haha - had just noticed this comment before coming on here to respond! Yes, I went from B to H, without the tweeners. Honestly thought I had read everything...
Did not see the note where flashing from 20H causes problems. Do you have a link for that?
Will go back and install E and F, at minimum, as he said massive changes happened with 20F. Really want this phone to work with AOSP rom's, especially since I paid around $250 for it, but willing to still use it stock and rooted. Phone before this was a Nexus 6, which I hung on to for as long as I could (over 3 years...) but after this, going to OnePlus or Pixel.
Thanks for your help!

Did LG developers website give u the unlock bin for this device? That would be the definitive indication of what device it is as there is only that one and the 930 you can get unlock codes for.
*If* that's the case, that LG identifies it for unlock purposes, then I can only say be sure to have done what's mentioned above in removing accounts etc. After doing that, and an aftermarket rom won't boot? I'd be at a loss. It really wouldn't make any sense at all.

LG NEVER gave bootloader unlock code for any US998U aka US998 V30+ (128GB). I have Open Market US998U (V30+) bought from B&H Photo and had to use WTF bootloader unlock.
Only my US998 V30 (64GB) bought from B&H Photo was eligible for LG bootloader unlock code, and even then you have to hack the LG Developer drop down menu to get a code. No US998 is listed on the LG Developer website.. LG never officially put the US998 on the approved list. Yes, for original B&H Photo 64GB US998, you can still get LG bootloader unlock code -- but you have to know how to do it. However, we have no need with WTF exploit.

Bought new SD card today and doing as ChazzMatt originally suggested, which is start at B, then do E and up. Stopping at G, and trying from there.
Thank you...but no thanks to the drama.
I appreciate the help but sadly, skittles-1999 offered the best response, which I must have overlooked when reading everything I did.
Phone was bought off of Swappa and assured by seller it was a US998U. Box stated as such, model number shows as LG-US998. KDZ downloaded/installed, from LG, was a US998. Cannot think of any other way to verify that it truly is a US998, original.
Things I have changed - new microSD card, 1, and 2, have gone from B, to E, F, to G.
Have to step out but will try installing lineage later.
Tried installing Lineage, Magisk, and Gapps all together. Will try to go back and reinstall just Lineage, to see if that fixes the problem.
Thanks for everything.
Erm calm down?

Can flash 20H zip, along with any other Magisk module, with no problem. Guessing it has something to do with boot.img?

Have downgraded to US998E. Is there a possibility partitions on the US998U have the same problem as others, such as the H931/H933? Would I brick my phone if I partitioned, using an H933 rom?
Tried installing bootlegger, with permissive kernel, but bootlooping as we speak. Have been at this, off and on, for days, with no success installing an AOSP rom but will try the suggestion offered. At the point I am ready to keep this as a backup and buy either an H930 or a US998, no plus.

No, plenty of US998U (V30+) are running AOSP/Lineage custom ROMs. US998, US998U, US998R are all identical internally -- except for storage amount or RAM.
If you wish to try H933 workaround, no you won't brick the phone.

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".

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.

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.

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.

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...
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 ChazzMatt. Thanks so much for the details! Oh boy - Seems doing this will erase all the data on my phone. I have had it for a few months now and not sure I want to wipe everything out. Not sure I feel confident to do the this. Is it worth it?

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.

Can someone she'd some light on how to fix this?

Ok using Lgup put my foot in it with complete wipe and flashing a kdz and now lost the imei number and whatnot can someone help.......please
You didn't lose your IMEI just by flashing a KDZ using the recommended Upgrade, Partition DL or Refurbish methods. You must have flashed using some mode NOT recommended in any of the Instructions. We specifically say to NOT mess with any modes not mentioned.

Why do you claim that?
You simply flash KDZ via Refurbish or Partition DL with Dev Patched LGUP and your phone is updated.
Most times you can even flash KDZ via Upgrade mode and keep data.
In ALL the KDZ threads we have, where users update their phones all the time, we only use Upgrade, Refurbish, or Partition DL modes.
What variant do you have?

The fact the update is out there and tried LG bridge and tried a few other ways to push the update to no success........it is a v30 us998 being used in Australia is probably the reason.
I'm using the device right now so it is only a cosmetic thing at the moment.

Follow the instructions in the US998 KDZ thread. We post all the KDZ images there, with several mirrors for each KDZ release.
You simply download the KDZ, flash via Upgrade mode with the Dev Patched LGUP -- which is also provided in the first post. At the most use Refurbish mode.
There's plenty of Instructions in the KDZ thread and how to use Dev Patched LGUP.
See Post#1.

The Dev Patched LGUP in that US998 KDZ thread works for everyone around the world -- unless the seller did something to that USS98 with Octoplus box which Matt may prevent that Dev Patched LGUP from working right.
I saw that one time before with AS998, where Dev Patched LGUP couldn't do anything because dealer had messed it up with Octopus/Octoplus box when converting it from LS998.

I have the box with the imei number on it......it is i reckon it is because someone didn't want to pay to get it unlocked by us cellular so they paid a third party to do it it has happened b4 to me......
Using dual mode LG UP in OP of US998 kdz thread and directions from post #6 on "how to get past stuck v30 logo", go back to freshly kdz 20h, H933 Nougat to get imei and partitions back, then 20e, then 20h, and lastly pie 30b

All US998 are already carrier unlocked. Even U.S. Cellular.
If you're trying to update to Pie it's a different KDZ thread. I assumed you were trying to update to latest US998 Oreo since to you said it wouldn't update...

Luckily you still have box with IMEI, etc.
You'll have to Google for tools to repair your IMEI. You know what it is, you will just need to type it in.
It's a touchy subject on XDA we can't really discuss in depth because some people for nefarious reason want to CHANGE their IMEI and XDA frowns on that.

What step do I have to follow to recover my V30? can i flash a kdz of us998?
please help

You need to use Dev Patched LGUP and you need to read the Frankenstein instructions.
Unless you're a Verizon customer it's probably better to use US998 firmware.

hello thanks for the help, you say it is convenient that I use LGUP and flash a KDZ of US998 in my supposed VS996? since I supposedly have a VS996 and LGUP detects me that it is a VS998.
Can the KDZ ROM be exchanged between these two models?
I am from Argentina and I do not use any of these companies, only the 3g and 4g bands that are the same in Argentina.
The next question is if there is any guide here to use LGUP since I did not find or know what words to use in the search engine because of my English translation.
Thank you !

Go to US998 20h (last Oreo, it's the best of the Oreos).
This first US999 PIE is wonky and some people have problems updating to it. We have a workaround in post #6 of the US998 Pie KDZ thread -- but it involves bootloader unlock and TWRP. It's a little complicated for anyone who isn't even rooted yet.
I'm suggest flashing to US998 20h (not 20b!) and staying there until another US998 Pie KDZ is released.
Hello again, I read the guide that happened to me kindly, but there are some points that were not clear to me and I want the advice of the expert experts here.
First when I install the LGUP from the link that happened to me I follow all the steps but I can not enable the developer mode and when I connect the phone I get this legend
Ask me to install a valid DDL, how would this be?

When I manage to open the LGUP from an icon that is in the folder where I unzipped the files, open the LGUP but it detects me as if it were a US998, at this point I would have to flash a KDZ of US998 on my VS996, with the method mentioned there?

If you are using the LGUP from the Frankenstein instructions, the .dll error means you didn't install it correctly.
I don't see you mentioning the SetDev.bat step?
After Installation, you launch Dev Patched LGUP by using the desktop shortcut, not through an icon in the folder.
Uninstall LGUP from your Programs folder, and reinstall.

Hi @ChazzMatt, I could finally flash it, I tried it on a different computer and with Windos 8, I detect the phone perfectly I could do cross flash, from US998 that detects LGUP to VS996, I perform the flash perfectly at 100.
But it is restarting in the Verizon Logo just as it was not restarting, it is still the same, try the master reset that they cite in the guide post, but I perform the master reset and it remains the same, the truth that I would not know what to do, Can't get into the android system, only the LG V30 logo appears and then the Verizon logo and it is loading, but from that screen does not happen, any other alternative to leave this part?

Your earlier screenshots show you trying to go straight to VS9930 Pie 30c from US998 Nougat 10c. Are you still trying to do that? Frankenstein instructions specifically say you have to flash Nougat first, Master Reset, then you can update to newer firmware.
This means you need to flash VS996 Nougat, Master Reset, then update to newer VS996 firmware.

Hi @ChazzMatt, I could finally flash it, I tried it on a different computer and with Windos 8, I detect the phone perfectly I could do cross flash, from US998 that detects LGUP to VS996, I perform the flash perfectly at 100.
But it is restarting in the Verizon Logo just as it was not restarting, it is still the same, try the master reset that they cite in the guide post, but I perform the master reset and it remains the same, the truth that I would not know what to do, Can't get into the android system, only the LG V30 logo appears and then the Verizon logo and it is loading, but from that screen does not happen, any other alternative to leave this part?

What I did was flash us998 kdz, install twrp, backup efs, modem, everything. Then did a chip erase in lgup.
Flash oreo Canadian kdz, then us998 kdz, install twrp, restore efs. Then flashed VS996 30c pie rom and like a miracle from Jesus it booted! [emoji106]

Flashing chip erase will wipe out IMEI and serial number.
Your phone was brought back to life by Octoplus or something a few months ago, right? So you have stuff in your phone that's different from most people.
In all the LGUP instructions I tell people to not mess with Chip Erase.

That was my original vs996. I got a second vs996 that I'm using now. If you backup efs, you can restore your imei. My serial is gone, but I don't need it, and now I can boot Verizon Pie.
OK never mind battery died overnight, charging now to go back to us998h.....
Ok converted v30 locked boot, no root us998h to vs996k, all went fine. it upgraded to L then tp pie vs996. Now just sits at verizon screen with colored dots. Did master reset and satill the same. Used partition dl for K and went just fine. How do I get back to phone off to redo vs996k and reject pie upgrade' Thanks

Hi all,
First some details:
LG930DS
secure startup enabled
H930DS30s_00_OPEN_HK_DS_OP_0902.kdz installed via LG Bridge. It changed me from AU to HKG for reasons unknown to me.
rooted with TWRP and Magisk 20.1 installed
I'm having issues with VoLTE not working (actually no longer in settings of the hidden menu) since installing Pie and I want to rule out the HKG variant as the cause. To do this I will install H930DS30c_00_OPEN_AU_DS_OP_0902.kdz instead. I have downloaded this kdz but now I'm not sure if I can install it without having to wipe and re-do all the Magisk and TWRP (and setting up all my files and apps again). After reading the guides none seem to answer this question quite right as they are mostly aimed and either US, EU, or India with their TWRP flashable roms like this one https://forum.xda-developers.com/lg-v30/development/us998-lg-v30-us998-us99830a000704-kdz-t3952256
Can someone with a better idea of how this works let me know the best option for me to switch over to the AU variant.

LG Bridge will look for the KDZ intended for your IMEI, not the firmware you have on the phone right now. Was your phone imported from Hong Kong (China)? Or did you buy from Australian carrier or Australia LG authorized retailer? Did you buy the phone new or used? Have you updated it before using LG Bridge?
Any H930DS can be flashed to run any other H930DS firmware. Best guess is somehow the phone was originally Hong Kong variant and someone flashed it to Australian firmware. When you went to look for update via LG Bridge, then it updated to that region Pie meant for that IMEI.
Unless you have used LG Bridge successfully before and you are sure it is Australian IMEI H930DS?

We haven't always had TWRP-flashable zips. Only thanks to generous, talented devs do we have the collection of TWRP flashable zips for US998, H931, H933, VS996, LS998, T-mobile H932, H930, India H930DS. That's only 8 of at least 20 variants and I'm not even counting all the different regional variants of H930DS...
So you will have to do what we all did before TWRP-flashable zips, and what we will have to do again when some of our TWRP flashable zip devs move onto other phones.
Method #1 -- Works some of the time on Oreo, not yet tried on Pie
This worked for many people in Oreo -- but some still had to reinstall TWRP, reformat data, reinstall the root files. Never could figure out the difference between success and not. Then we got TWRP-flashable zips and the issue became moot.
1) Make backup in TWRP AND make backup of all apps in Titanium Backup.
2) Flash new KDZ via Pie-compatible Dev Patched LGUP in Partition DL mode, but omit the Recovery partitions. Do NOT select "all partitions". This will let you keep TWRP.
3) Boot into TWRP via fastboot commands from your computer, just like when you first installed TWRP using the WTF instructions. (Best not to use the stupid hardware button dance.) Once in TWRP, then choose Reboot to Recovery (from within TWRP) to get the actual internal phone TWRP, instead of the PC TWRP.
4) Flash the Pie-compatible three root files (Magisk, encryption disabler, root check disabler, Magisk again). See attachments on this post to download those files.
5) Restore all Data from within TWRP. Do not choose any other categories.
6) Wipe all Caches.
7) Reboot
Restoring all TWRP data may or may not overcome the fact that you have re-flashed encrypted stock Pie on your phone. IF it does work, then after rebooting the phone if anything is still wonky, use Titanium Backup to restore all apps and data (this is in addition to the TWRP data restore you did).
Good luck.
Method #2 -- Works all the time, but yeah you have set up your phone again
1) Flash new KDZ via Pie-compatible Dev Patched LGUP in REFURBISH mode.
2) Your phone is now on the region KDZ you desire and you still have unlocked bootloader. You will need to reinstall TWRP, and then flash the three root files (Magisk, encryption disabler, root check disabler, Magisk again). This includes the step where you reformat all data with a "YES".
See instructions here:
REINSTALL TWRP on PIE stock KDZ with ALREADY-UNLOCKED BOOTLOADER
THAT POST ASSUMES YOU HAVE PREVIOUSLY UNLOCKED BOOTLOADER, AND THAT YOU HAVE NOW UPGRADED TO STOCK PIE KDZ. YOU HAVE UNLOCKED BOOTLOADER and are STILL on firmware which has FASTBOOT FLASH COMMANDS.
___________
Dev Patched LGUP
Dev Patched LGUP vs regular LGUP is necessary when cross flashing across regions or other variants. You will need this for either of the two methods above.
Here's how to flash with LGUP:
UPGRADING LG V30/V30+/V30S TO PIE KDZ FIRMWARE WITH LGUP
1) Go into download mode (power off completely, then hold volume up button while plugging in USB cable)
2) open Dev Patched LGUP and flash PIE KDZ either via PARTITION DL MODE (but omit Recovery Partitions for your purpose in this thread) for Method #1 or via REFURBISH for Method #2.
Use the attached patched LGUP in this post. If you get a ".dll error" you either didn't install correctly or are using the wrong version of Dev Patched LGUP. Read the installation instructions carefully. Some people have used OTHER versions of LGUP before and ignore the installation instructions -- they think they know how to install and they do NOT --- then complain about .dll error, which is their fault.
* NOTE: YOU CAN NOT USE LGUP "UPGRADE" MODE IF YOU HAVE TWRP CUSTOM RECOVERY. LGUP "Upgrade" is like a manual OTA and is only for pure stock (but you can have unlocked bootloader).
3) IF your bootloader is unlocked, it will remain unlocked after flashing KDZ.
_________________
HOW TO INSTALL DEV PATCHED LGUP
0. UNINSTALL any prior LGUP version. Seriously. Go to Programs folder and delete the LGUP folder if you must.
1. DOWNLOAD THIS DUAL VERSION OF DEV PATCHED LGUP, made by @tecknight:
https://androidfilehost.com/?fid=11410963190603845019
(Or use attached file from bottom of this post. Thanks to @tecknight! Please go here and click the THANK BUTTON!)
2. Extract LGUP_DualMode.zip to a folder on your PC.
3. Browse into the folder and launch LGUP_Store_Frame_Ver_1_14_3.msi.
Follow the prompts to complete the install.
4. In that folder, right click and select "Run as Administrator" on "SetDev.bat" to set LGUP to developer mode. < READ THAT AGAIN.
5. Launch LGUP using the desktop shortcut. NOT from folder icon!

It's all fairly easy. Most people breeze right through this. But if you have any problems, go through this list:
Make sure you in download mode BEFORE opening the patched LGUP file.
This is at the top of the list as some people forget to do that. The remainder are in no particular order. If that doesn't work,
Try different USB port,
Try different USB cable,
Try different computer.
Reinstall LG mobile drivers on your PC.
Reinstall dev patched LGUP again.
Reboot the computer.
If you ask for help, that's the list of items we are going to give you anyway.

Ahh thank you for explaining this. I imported mine from Hong Kong. As far as I know it was never sold new in AU.
I'm about to rush off to work for the day so I will have to try this when I get home tonight and let you know how it goes. Thank you so much for the detailed and fast response! This is much more than I was hoping for!
One last question. Do I need to disable secure startup or does the encryption work with the method #1?

I don't know the Australian market, but we have an Australian XDA moderator who has or had Australia H930DS. Since there is Australia H930DS firmware, I assume it was sold new back in 2017/2018 by some carrier or by LG authorized retailer.
He has Vodafone in his profile. @Redline.

This is correct. I bought one BNIB from an eBay seller, a H930DS and it was only a couple weeks old from the factory. Came pre-loaded with AU firmware and I updated it to the latest. Before going the LineageOS route.

Interesting to know. I bought mine back in 2017 but I couldn't find it in AU and read somewhere that imports were going to be the only option. To bad for me.
I know little of what IMEI's do. Is there any issues related to regional OS versions and the IMEI of a device? Is the hardware otherwise the same?

I could kind of answer is the question of if the hardware is otherwise the same, the rest might be a question for ChazzMatt.
AFAIK the modem on my H930DS was the same as other similar models, similar to the V20 you can flash a KDZ from another region if you wanted to (to for example, get less bloat or better coverage on a band you rely on for service). I remember on my V20 the region that had Claro-carrier firmware came with the least bloat out of the box vs other regions, but we also had KDZ Writer with the V20 that allowed us to flash specific parts of the KDZ *in* TWRP on the device itself, so you could have, say, Claro firmware with the AU modem.
As for what IMEIs do, they're similar to the MAC address on a piece of networking gear; it's a globally-unique identifier specific to your device, you can put it into IMEI lookup websites to get information about manufacture date, model etc.
If you have a carrier-model phone, they can also block your IMEI on their network if it is stolen and then attempted to be re-used.
I've had to opt with #2 as the encryption was a problem as you suspected. I'm puzzled though... while I was setting up for USB debugging I noticed that I had VoLTE in the drop down menu, however, calls still reverted back to 3G. I didn't pay much attention to it as I had to do a format in the steps to follow. Now that I'm back up and running I no longer have VoLTE in the drop down menu? It's the only icon missing. Calls still revert to 3G again. I'm on the boost network which uses Telstra and this phone is listed as compatible for VoLTE with them. I know that it worked in Oreo too.

Hmmm.... Sorry, I don't know. But you are back on Australian firmware.
If you wish, you can use the same procedure to downgrade back to Australian Oreo to see if you can get VoLTE back.

Out of frustration I started doing random things just to test there effect, much of it being in the hidden menu where I discovered VoLTE settings. Nothing was working until... I force stopped the carrier service and made a phone call. Presto! VoLTE now appears (though not listed under any setting in mobile networks, or in the drop down menu) and my calls say HD call. Finally to confirm 4G remains active and still works during a call!
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.

Ahh, alrighty, I understand the difference now. So I had Frankenstein'ed to unlock my bootloader, then unlocked it with "WTF".
Also, the IMEI checker reported my device as a US998U V30+, which was what I bought it as used.

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.

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.

Should I attempt to Frankenstein to a different variant then come back? I was going to try to use the fourth method that you linked to before to try to put myself on an actual US998.

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.

As someone who doesn't necessarily mind the extra preparation, would you recommend it for someone in my predicament? And is there any log file I can provide to hopefully help give more insight?

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).

Though if I am to do that, would I still keep the bands I have at the moment or would I lose them when converting? Would I have to refflash my modem partition(s)?

The method is flash to H933 Nougat I believe, then flash back to US998. You don't stay on H933. You flash everything via LGUP Partition DL mode.

Ah alright, I'll try that. So just to clarify, I'd flash over to an H933, then come back to a US998, and then install the 30b kdz, and that should hopefully fix my issues?

Yes. But read Method 4 carefully. Involves timing and buttons.

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
