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..

Yea. Then went to restore and the restore wouldn't even work anymore. Was saying there was no partitions backed up but I had use that restore numerous of times trying to get los to boot very strange had to start back from scratch
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.
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.

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.
@Klenon
Bottom of op or you can flash Sprint system

Okay, thanks for the heads up. I'll try to follow that tomorrow and let you know how it goes.

I have a LGv30 VS996 that has been bootloader unlocked using WTF and is currently flashed and working great with a US998 stock firmware.
I would like to use VOLTE/VOWIFI but it is not showing up as an option for me.
My local region (I'm in Asia) uses the H903DS variant of LGv30 and they have a stock ROM for that device which I'm hoping will enable the VOLTE/VOWIFI options.
My question is, will that work? Are VS996/US998 similar enough to H903DS that I can cross flash?

Uhmmm... You can't fully CONVERT any North American phone to any H930* phone like Frankenstein can do to each other with most North American variants, but you can flash parts of the H930DS software to VS996 via Dev Patched LGUP in Partition DL mode. However, you have to OMIT certain partitions, like modems and XBL.
People have done this to flash EU H930 firmware over US998 to get East European languages, etc. Every time you flash an updated H930* KDZ, you would have to remember to omit those partitions. You would NOT be changing any bands like with Frankenstein.
See this guide, but change to H930DS KDZ instead of EU H930:

Select all partition except the following 3: modem, xbl, xbl 2, click Ok and accept partition changes
Let it complete and restart, if you stuck on LG logo, try reboot again, it will boot completely
Result: H930 30B on a US998 with working network and stuff working (testing on GSM network outside US only, cant confirm Vowifi, VoLTE or any other netwrok stuff.)

Read that last sentence.
Good luck.
I've been on Page Plus (Verizon MVNO) for a couple of years with this phone. I unlocked the bootloader and rooted it via Frankenstein and WTF methods. I just switched over to Mint (T-Mobile MVNO) and am missing a couple of features on the VS996 rom. I'm also getting incoming calls going straight to voicemail. I'd read that flashing it to US998 could fix it.
How can I flash it over and which stock rom should I use? Can I go straight for US998 Pie or start with Oreo? Can I flash the zips through TWRP or does it have to be through LGUP? I've been wading through a ton of posts for hours and can't seem to find a definitive answer.
What ROM are you coming from? Nougat, Oreo, Pie? That makes a difference...

Yes. For one, on VS996 firmware you don't have LTE band 12, which is very important to T-mobile network. US998 will give you that, plus US998 firmware will handle T-mobile VoLTE. It should also handle that on T-mobile MVNOs.
Do NOT try to flash actual T-mobile firmware onto anything but a true native T-mobile H932. I'm sure you understand that, but reiterating for others.
Instead we will be flashing US998 firmware back onto your VS996 phone.
When you used WTF you had to temporarily flash early Oreo US998 for fastboot flash commands, so you were on US998 at one time. We are just going back to US998, but more recent firmware.
Either flash last Oreo US998 20h or Pie US998 30b. You would use the TWRP flashable zips, NOT KDZ. With the TWRP flashable zips you can flash straight to those.
The Pie US998 firmware is a little wonky. Many people get stuck on the LG logo and then have to go down the rabbit hole of tedious workarounds. I am still on last Oreo 20h US998 for my daily phone, even though I flashed to Pie on a backup phone just to prove it works.
Even though these threads are labelled KDZ, you will also find the TWRP flashable zip versions there side-by-side:
[US998][STOCK][OREO]LG V30 US998 US99820h_00_0318.KDZ
NOTE: You possibly can just flash US998 20h, when going from VS996 later firmware. However, you may need to flash 20e, 20f, 20g and 20h all back-to-back. For the Oreo TWRP flashable zips they were incremental to some degree and just flashing 20h only may not be best case scenario. We figured out 20e, 20f, 20g, 20h was a good combination. I know this is true when going from US998 20a or 20b. I do not know if this is necessary when going from VS996 last Oreo or Pie to US998 20h. Just giving you more information.
[US998][STOCK][PIE]LG V30 US998 US99830b_00_0902.KDZ
If you use this and get stuck on LG logo read ALL of post #6 for various workarounds.
What VS996 firmware are you on? Pie or still Oreo?
Thank you so much!
I have everything working, as it should. I'm getting calls, AND I have wifi calling now. I didn't have it on VS996 after switching to Mint from Page Plus.
I was on VS996 Pie and I had to flash E-H. I first tried just H, but it went into a boot loop that was really fun to get out of because it wouldn't let me power down. I had to wait til it went to the Unlocked Device screen to get into TWRP again.
Now, I have to debloat and install everything again. No biggie. I've done this a million times with my other phones.
Thank you, again.
I hope this can help someone else.
