I have an LS998 on Oreo already I am going to use on Sprint service that I want to root. I have read the stickies and tons of posts about the process but I want to make sure I am understanding correctly. In order to root the phone must be flashed to the US998 KDZ using LG UP first, correct? Then basically follow this guide: https://forum.xda-developers.com/lg-v30/help/wtf-lg-v30-t3790500
I am having a heck of a time getting LG UP to work properly, it says no handset connected but it is and I can find it with ADB. Help!

In my Frankenstein thread post, you saw where you have to install LGUP in a specific location on the PC?
Also you saw where you go into download mode BEFORE opening the patched LGUP?

Thanks! Got that all figured out got US998, TWRP, and Magisk installed. Now my problem is called Sprint and they activated it but the phone wouldn't take the activation. Anything special to get it to work on Sprint? Tried the modem flash I saw in another post.

Glad your got that part figured outout.
As for the Sprint part, probably you should have the phone activated before doing this...
Maybe @JWnSC can help you or another Sprint user?

Backup your current setup in twrp first. You need to restore the stock rom in order to do a prl and profile update to get calls and lte working. The Sprint nandroid is in the same thread as the modem.bin you flashed. After, you can restore your backup you did prior.
Sprint users need to dump using lg up before flashing to us998 if they are planning on staying with Sprint. There is no LS998 kdz the only way to return back to stock is to flash the bin files you should have backed up(using dump option in lg up). I can share some files but some are phone specific.

I have an HTC10 that is activated which is what I am trying to switch from to the V30. I wonder if I switch the SIM card from that if that would help the activation since it's already programmed with the number I am trying to use. Willing to try anything at this point!
You need the Sprint V30 sim card. The Sim from the HTC10 is most likely a different model sim.
Once the Sim card is matched to your device IMEI in sprints system, it will allow it to activate using the self activation. Not sure if a US998 rom will allow that. I know on unlocked s8s and s9s thier unlocked firmware works.
I work indirectly for sprint, so my knowledge may actually come of some use lol

Yep. Mine looks the same. No need to reflash the backup you made unless you want to. The Sprint nandroid was so you could update prl and profile if needed and to get lte working.
If you restore the US998 backup it will show model number as US998 instead of LS998(unless you swap the build.prop). Not sure where it reads the software info though.

Do you know of any way to fix the SD card corrupted error message? I think that's based on the kernel not recognizing it.

Not sure. I think that's the ls998 kernel. I'll try reflashing the system.bin later to check.

Hi everyone, I've followed the WTF thread to unlock the bootloader on a V30 H933 (the Canadian version), but even after unlocking there's no fastboot support on the phone, only the US998 version seems to have it. Trouble is that Rogers, my local operator, only supports VoLTE and VoWiFi on their recognized devices - I tried having US998 running on my phone, calling their support and possibly getting some actual configuration I could put on the phone, but their response was "your phone is defective and needs to be replaced".
All that said, my goal here is to somehow install TWRP on this phone and root under the original ROM, so I can have the features I need from the network. So far, I've been pretty unsuccessful in this, so my plead would be: could anyone chime in to help me either
flash the minimal necessary over US998 to get H933 functionality/network information back as to reenable VoLTE and VoWiFi on my operator
come up with an update.zip or some other file I could use to flash a Magisk-patched boot.img
pack a full flashable ZIP image of the Canadian ROM (my last attempt at this left the phone in bootloop)
an alternative idea I haven't thought about that could help?
Ideally, at the end of the process, I'd like to have TWRP and Magisk installed on the phone, but I could settle for simply Magisk.
Once again, any help or pointers are more than welcome and appreciated.
I think you can extract a h933 kdz and flash individual partitions that do not have to do with recovery or the bootloader. You can probably use the dd command for it. I think the partitions you dont flash are anything with boot in it, abl and recovery. There may be a few more however.

I tried something similar, extracted a KDZ and put the necessary BIN files on a flashable ZIP I found around. All I achieved was bootlooping the device...
I have an H933 on Freedom Mobile, and running the stock FM firmware. The loss of VOWIFI (and VoLTE) are exactly what i thought would happen if I proceed with flashing to US998.
I think #1 is right; that you may be able to restore access to network specific functionality but it would depend on being able to isolate the specific required "patch".
With this in mind, take a look at this post from the WTF! Thread:
https://forum.xda-developers.com/showthread.php?p=76613814
That user flashed some files (modem binaries from the original device firmware I think) and was able to restore VOWIFI and VoLTE functionality on the Verizon network.

What menu is that from @cre4per? Have you had the opportunity to confirm staying on LTE while receiving a call?
That would be good news to hear VoLTE working on a Canadian network using a generic phone model (instead of proprietary stuff).

Looking at this this morning. I don't think that is an indication that you are connected to a VoLTE service; just that your device is ready to accept it if the right service becomes available. I have that switch turned on and the service menu even says the voice network is LTE too (see image below) but Freedom Mobile doesn't even offer VoLTE service so it isn't possible that I actually have VoLTE operational.
I would interpret the LTE provision switch as turning on or off the functionality in your device, not a connection authorization from the network. Sort of like turning on the HD calling option on your device; it allows the possibility but won't do anything unless the service provider has the capability and authorizes it on your connection.
If someone has VoLTE working, could you check the menu cited by @cre4per, then hit the options (3 dots) and in there, select IMS service status? It lools like this is where you *should* see if the network has connected you to their VoLTE service (see image below).
I don't know how to interpret the, "Voice Network: LTE" on the main menu screen.
Just check and switches to 3g on calls also when going into that ims menu says unavailable

As @Mad Medik mentioned, so far I don't know of any Canadian operators enabling VoLTE (or VoWiFi for that matter) to generic phones. I have a Rogers P10 Plus that's registered under my account as my main phone and which I reflashed to have these features available, but it just won't work. I've had extended arguments with Rogers representatives about it, and the 1+3T I'm presently using even have the same config your phone is showing: VoLTE Provisioned, but IMS shows as Not Registered so nothing else works. I'm waiting on an LS998 I bought to arrive, I'll try flashing H933 on it to see if it actually allows me to register on IMS.

KDZ was for Oreo, indeed. It was the one I used to bring the phone to the latest (at the moment) update available.
As for which partitions I flashed, I was gonna give you a list, but to make it short the only partition not flashed was recovery.

As far as I know there are some boot partitions that should not be flashed, which may have caused the soft brick. I know autoprime used to make these zips for the G3 and runningnak3d made one for the V10, you might want to cross reference the partitions they used and what they didnt. Probably the V10 first because the G3 is relatively ancient. I think in essence you should just be able to flash boot, system and modem and rpm though, but you would need 2 combine the split up system images after the extract.

The reason why I was flashing everything is because I used this thread to recover from a previous soft brick I stumbled upon. Upon speaking to the thread creator, he mentioned I should be able to follow a similar process to achieve an H933 flashable file. Did that and, well, managed to soft brick the phone... I might try your idea, though.
So, from my knowledge of attempting to get VoLTE working on an HTC 10, I suspect you won't get VoLTE working on anything other than Rogers H933 firmware. For whatever reason, the programming required for VoLTE isn't on the USIM card in your phone, but rather programmed into the phone by the provider. This means, unless your phone model is sold and supported for VoLTE on the provider you wish to use it on, you're screwed like I was, trying to get VoLTE working on my HTC 10 on Rogers.
This being said, the good news is we are back to CDMA tech here, where the only thing preventing you from using your third party phone with your provider is knowing what code to enter, and what parameters to program in. Since my H933 is on Telus, my programming won't do you much good.
What you're looking for is the IMS settings or IP Multimedia Subsystem settings, as this is what carries the VoIP packets that consist of VoLTE. If someone were to post the settings from their Rogers H933, you may be able to get VoLTE working on US998 firmware.
Why not just flash system and boot? After unlocked and rooted of course.. Lg up partition DL will let you flash individual partitions. I would have done it that way for my carrier but there is no kdz available..

Anyone with H933 from freedom mobile convert to US988? I'm just wondering how the service is after the change. I'm reading mixed reports but once modems extracted and compared there was a difference.
Anyone else get a notification for an Android system update today? I just received one and haven't clicked it yet...
Added screenshot. Appears to be a security update.
I was under the impression that since my phone is rooted and Bootloader unlocked that I wouldn't receive security updates through play services. Apparently I was incorrect though.
Anyone know if this is safe to install or more specifically if installing it will effect my root status? I've switched back to the LS998 w. 21a update currently.
I installed the security update and all seems ok. I'm not rooted, so there's that also.

Side note, is there any way right now to unroot and put stock recovery on to get the update then reflash TWRP and re-root or would you lose the update in the process?

IIRC for this, one needs a KDZ. Since Sprint does updates via FOTA, KDZs don't get released.
Updating requires someone to repack the update. Or flash the US998 KDZ, flash modems, edit APNs.
Last week I flashed my girl phone to sprint21a and forgot to root(flash Magisk)so she update her phone sometime in the last week and today when I tried to play around on her phone it was a no go
No more fastboot even though phone says it's bootloader unlocked .. I'm open to any suggestions .. going to try a few things tomorrow (Don't really care to much cause it's not my phone)
SO YEAH DON'T UPDATE LOL

Saw your other reply in the US to LS thread. Oddly enough something weird went down when I was doing that and I flashed the LS version back along with root to get my LTE back, yet my software version still shows up as US. I dunno if that guide just flashed the modems back leaving the software version or if it should have changed the software version back to LS, but I've got a running phone with root and sprint APNs + LTE so I'm happy with it even if the software versions messed up.
Haven't seen any new US998 KDZ files though on xda (or google for that matter). Guess I'll have to wait and see if someone releases a new file that goes past the 99821a that I currently have, as thats the only one that appears to be available right now on here.

Typo. While 20D is the most recent, 20B was prior, and 20A before that, for US998. 20A is the first (oldest) US998 Oreo KDZ.

This is a bit odd then.. I'm on sprint.. The version I have is US99821a according to the software info page. I had followed JWnSC's thread for restoring LTE bands for sprint. I had the US998 software from your guide installed before flashing over his version. I had assumed that would set the version back to LS99821a but evidently I was wrong. Where exactly would 21a fit into this update timeline?
Assuming 20d is the most recent in this case, would the xda link I posted in my previous reply be the correct one to flash over? And if so, would that mean that JWnSC's files for restoring the LTE bands wouldn't work? I apologize if these questions seem dumb, I'm just trying to wrap my head around all of this.

US99821a. I had assumed JWnSC's guide was going to revert this back to LS but it doesn't appear to have done so, but I have my LTE network restored. I've attached a screenshot of it. For what it's worth the phone's model number shows up as LS998 under the hardware info.

I'm wondering if something got mislabeled in JWnSC's file then... The file I had flashed to restore LTE and sprint APN's was the sprint 21a (May security patch) linked in his main post on this thread:
https://forum.xda-developers.com/lg-v30/how-to/us998-to-ls998-sprint-lte-root-t3802310
I did notice the first time around I was rooting the phone I flashed the sprint 20b image first off, then when I got a notification there was an update available someone else told me to use the 21a zip which was right below the 20b. While I was running 20b both the model and software showed LS after flashing it. Is it possible this is merely a typo somewhere within the 21a zip file?
In any case, should I avoid using the 20d files I found posted by you and westwood24 and then trying to flash the modem bin for sprint LTE over?
The entire reason I brought this up is because I've been getting notifications that theres an update available now for the system. Since I'm rooted and TWRP'd and don't want to lose either of those I figured the only way I could get it was to come back here and find the update file and flash it.
EDIT: after doing some more reading on the sprint specific update that occurred at the same time as the update OP was mentioning, it turns out this update is named LS99822a. As far as I can tell, theres no KDZ or zip files for this specific update on xda, or anywhere else for that matter. So I guess I won't be touching this 20d update or flashing this 22a one whatsoever.

It's normal maybe a type-o somewhere or result of flashing us988kdz
@txag2011
You can flash latest us998 and then flash modem and it will be fine the only thing is that sprint visual voicemail won't work right out the bag and sprint calling plus you won't be able to upgrade prl or profile that the only difference I see but you may or may not use other sprint stuff
If you want to run Sprint's latest and you don't need root you can always update
Last week I updated to Sprint's ls99822a as you can see on my screen shots(last page) Lost root and fastboot commands but bootloader stayed unlooked and I was able to downgrade back @ChazzMatt
When I downgrade I saw lgup checking for antirollback and it was all good
That was on sprint latest software security patch August 1

@txag2011
You can flash latest us998 and then flash modem and it will be fine the only thing is that sprint visual voicemail won't work right out the bag and sprint calling plus you won't be able to upgrade prl or profile that the only difference I see but you may or may not use other sprint stuff

So aside for the sprint LTE bands and calling plus, theres zero difference between US99820d and LS99822a? If thats the case I might give that a shot. Still havent heard any confirmation if the forum post I linked to a few posts back was the correct update (it's from westwood24, titled US99820D(TWRP).zip) In addition to that I'm not sure how exactly I'd go about obtaining the modem file let alone flashing it. Is it particularly difficult?
What did you end up doing with yours once you downgraded away fro m22a? Did you end up trying to flash US20d over and patching the modem yourself or are you just staying with the 21a built JWnSC did?

both and more ...
currently I have 4 nandriods backups I f__k around with ( US998d,Sprint 21a, AIS and Dotos )I also like trying out all aosp roms
Which os I run depends where I'm working at if I'm out where service is bad I use sprints for the calling plus feature other then that it depends on what mood I am
(Visual voicemail dosen't matter much to me if I got a lost call I can always check voicemail manualy)
I lguped us99820a then dirty flashed us99820d

Thats an impressive setup you have there. You must be pretty damn adept at this kind of thing.
So you just used LGup to put on chazzmatt's zip using the partition DL function and then... I'm sorry, still new to this, what exactly is dirty flashing? Is that flashing the 20d zip file under TWRP or also in lgup? and afterwards you flashed the sprint modem?
I've been getting the Android update notice the past few days. Regardless of what gets frozen in TiBu it doesn't seem to do the trick.
I've had some serious issues trying to update my phone via using LGUP to flash a updated US998 KDZ, and then editing apn's to allow service thru Sprint, who is my carrier. I am of course, frankensteined to a US998, then back to a LS998 using @JWnSC's Sprint 20a zip file.
Can I flash the US998 KDZ via LGUP, and not flash the modem files, or recovery partition? Then flash magisk, no_verity, rctd in TWRP? Will this allow me to keep my phone up to date while staying on Sprint?
can someone idiot check my procedure that I'm going to attempt, if the previous question didn't pan out, please?
Need to back up my modem/modemst1/modemst2 from my currently known good setup. Place those on SD card.
Flash US998 KDZ, skipping recovery partition.
Boot to TWRP.
flash all 3 modem files (modem, modemst1, modemst2) as an image file via TWRP.
Boot phone. Setup via wifi.
Edit apn's that I copied down earlier.
Reboot.
Disco?
I'm apparently a bit of a Luddite when it comes to doing things other than via 0din.

The steps you listed so far would work to keep TWRP, but you would need re-flash the three files you flashed when you first rooted, since you are going back to stock (except keeping TWRP): the no encryption file, the no root check file and Magisk.
OR
You can also flash the 20D US998 TWRP-flashable zip file that @westwood24 created for us.
After that, you still need to flash Magisk -- but he already has the no encryption file and no root check file built into the image.
[ROM][US998][Stock][OREO] LG-US998 20D ROM
You would then do the other stuff you mention about Sprint to get those LTE bands back...
Dont have a clue.
CAN ANYONE POINT ME IN THE RIGHT DIRECTION TO GET A LG V30 THINQ VERIZON FLASHED TO BOOST MOBILE and not loose 4glte and most of the features?
Used the Frankenstein method to root my ls998 as well. Flashed back to the ls998 rom. I keep getting update notifications as well, is there a way to flash it in twrp? I tried the us998 rom, but didn't have luck getting my service/lte working.

Boost is Sprint minor leagues, right? Problem is does Boost accept Bring Your Own Phone? Because Sprint won't accept any V30 not ID'ed as their own LS998, and won't even let Sprint MNVOs accept US998 V30. So, people have to first activate their LS998 on Sprint, then flash to US998 (Frankenstein) for bootloader unlock, then change back parts to get all the Sprint LTE bands. It's been done by many on Sprint -- but you are throwing in a new wrinkle with Boost. Also, you are starting out with Verizon VS996.
Would be better to start with LS998 (mint on eBay for $315 last time I checked) or choose another provider.
Only phones on a list sent to Boost Mobile from Sprint are acceptable Sprint branded phones that can be reskewed for Boost Mobile. Other then that you would need to buy a Boost Mobile branded phone.
Could you post a snapshot of all your apn settings for Sprint? I've updated my phone from the LS998 to the US998 and I just cant seem to get my apn settings right.
As of right now, I finally got 4g lte (albeit slow, which could just be the crappy sprint towers near me). But my text messages are acting really weird.
As of right now I'm only receiving text messages when I receive phone calls, and I am not receiving voice mails.
I can send out text messages just fine though. This apn part is kicking my butt.

You can flash stock rom by using lg up and kdz. Make sure you use the correct kdz file for it.
Keep in mind, KDZ flash will erase your data, so be aware of that.

Yep. If you can get some kind soul on here to extract the stock recovery and turn it into a flashable zip, then you can download it, boot to TWRP, flash it, and viola -- stock recovery.
It doesn't matter what model recovery is from -- they are all the same with the EXCEPTION of the H932. If you have an H932, you must use the H932 recovery. You won't brick your phone, but you will be flashing a KDZ if you ever want to take OTAs again. Also, if you don't have an H932, do not use the H932 recovery -- same outcome.
EDIT: if your phone is rooted, you will not be able to take OTAs (the hash check will fail). So, if it is rooted, you need to unroot it (install Magisk manager) before flashing the stock recovery and taking OTAs.

Ironic you wish to remove TWRP from your phone when for several months that's what we would have given large sums of money to have. Finally in May 2018, the WTF exploit allowed us to do that. You can root your phone, since you have TWRP and install recent TWRP-flashable zip based on stock firmware.
But if you wish to return for full stock without TWRP custom recovery, you will need to use LGUP to flash stock KDZ. And yes that requires a PC.

I'll have to let one of the Korean users answer that. I'm not an expert on the Korean models. They have to do extra step to get TWRP, root and get radio back. So if your phone works and has TWRP then at over point in was rooted with Magisk.

If you are going to keep TWRP then I won't bother, but if you want to go back to stock let me know and it just so happens I have that KDZ sitting in my archives so I don't even need to wait 40 years for lg-firmwares.com to download

Sorry -- I just haven't had the time -- and it doesn't even take that long. I have a few minutes right now, let me see if I can throw something together for you.
Keep in mind, that I have no way of testing it. It won't brick your phone, but I might have a typo and it will just fail (I have a tendency to have typos ;P ).
If that happens, you will just have to tell me where it is failing, and I will fix it. *crosses fingers that I have no typos*
EDIT: I am not going to do something half assed. I am grabbing the latest firmware available on lg-firmwares (V300K21r) and going to make a FULL zip.
As long as you don't wipe data, even if you are on a lower version, you should be able to flash it and keep your data. I will flash all the partitions that usually get flashed when using a KDZ.
I should have it up in about an hour.....
EDIT2: It is up -- https://www.androidfilehost.com/?w=files&flid=286970
Download and flash that in TWRP. Wipe cache / dalvik. Reboot and you will be fully stock. Again, you should only lose your data if you factory reset or wipe / format data.
Enjoy,

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.

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.

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.
