you can't update using OTA updates.

I got H932 with TWRP and Oreo installed, but this phone is locked to T-Mobile for me to unlock I have to put the phone in download mode, since there is TWRP installed how can I get back to download mode without messing things up? Because when I try to go into download mode it takes me back to TWRP.
You didn't use this WTF method with T-Mobile H932! Otherwise you would have a bricked phone. T-Mobile H932 can NOT be flashed to any other firmware, except for other T-Mobile H932.
To install TWRP, you probably used the T-Mobile H932 laf exploit, found here. Go to that thread and ask, because they are the T-Mobile H932 users.
To carrier unlock T-mobile H932, you will need to use T-mobile's app which uses their servers. If that doesn't work there are some tricks... Some people have been able to downgrade to Nougat, spoof another T-Mobile phone and carrier unlock that way.
You can unlock H932 using this method without any issues see this video
for that method to work I have to have download mode, since I followed your WTF V30 H932 guide I was able to root my phone, but I found that method later on that why I was asking to get the download mode back. Is there any way to get back the download mode without messing anything up? Since it's replaced with TWRP.
I replied to you about this in the H932 root thread.
TBH I think you should ask moderators to delete your post here (along with my reply) as nothing in it has any relevance to WTF, nor to any model other than H932
From PM. I don't read PMs often. Mostly I just don't see them for some reason. So, the best way to reach me is to post in a relevant thread. I check new forum posts at least every other day. With two new adopted children, I don't have as much free time.
But when I do read PMs, I like to reply publicly so the answers can help others. This seemed the best place to post the answer.
This answer is specific to North American V30 models (EXCEPT for T-Mobile H932).

can you help me ? i need to trade in my lg v30 from VZ and i couldn't figure out all the steps to revert it. its currently on Android 9 30C.
thanks in advance for your help.

Answer:
You will need to re-lock the bootloader on full stock firmware, which has fastboot flash commands (US998).
Then you will need to flash back to Verizon firmware.
So, we will just reverse the steps you used in these WTF Instructions.
1) You will flash any Oreo US998 or Nougat US998 KDZ in Partition DL mode. You ONLY have a choice of this because you have Verizon VS996. Any other North American variant which can flash US998 firmware (NOT T-mobile H932!) would HAVE to use Nougat US998 for this step. (Like Frankenstein.) But VS996 is very compatible with US998.
Do NOT use Pie US998 KDZ. It's too wonky and we are just going to US998 TEMPORARILY to relock the bootloader. Use any Oreo or Nougat US998 KDZ. Doesn't matter which one. This step is only to get fastboot flash commands.
We are using KDZ, NOT TWRP flashable zip, because you need FULL stock firmware. NEVER try to relock bootloader unless you are back on full stock firmware with full stock recovery. TWRP is "custom recovery" and you need to get rid of that.
2) After successfully flashing US998 KDZ, then run these commands:
adb reboot bootloader
fastboot oem lock
fastboot reboot
Your bootloader is now relocked.
3) Now we need to get you back to stock Verizon firmware.
Using Dev Patched LGUP, flash your choice of VS996 KDZ firmware in Partition DL mode. Can be VS996 30C (Pie) KDZ if you wish.
You ONLY have a choice of this because you have Verizon VS996. Any other North American variant coming from US998 would HAVE to use their carrier's Nougat first, Master Reset, then go to Oreo or Pie. Like Frankenstein. But VS996 is very compatible with US998.

Interesting, it's just adding a few registry keys... so it's simple. That also means we could easily remove it if it's not working... I may test it out over the weekend if I have time...
I trust you, so I've added it to the Trouble Shooting Tips, with link to this post. So, there's no longer 12, there's 13 tips!
I've also installed it on my own PC. But I've not done anything yet to test it.
I also found out with this new board, I don't have the character limit I was running across on the old board with the WTF Guide. I was literally down to almost no additional characters (letters, punctuation) I could add to that Guide if something needed changing.
Hi, I'm in Australia with a Australian version of the LG V30 Plus. I'm trying to complete this procedure but every time if fails with Error!! Wrong Bootloader Unlock key: 3006. I have tried various version of ADB and everything that is suggested. Am I just out of luck? Do we have some crazed Aussie version of the phone. Help is appreciated
Regards
Regards
This guide works for every V30/V30+/V30S except for T-Mobile H932. Many Australian H930DS have used it. In fact, at one time an XDA Moderator had a rooted Australian H930DS. He, of course, used this guide.
"Wrong bootloader unlock key" suggests perhaps you haven't temporarily downgraded to the proper firmware needed for this bootloader unlock exploit. What firmware are you on?
You've read Section 9, the Troubleshooting Tips?

Yes, see the Prep Section 3, point #5. Also read in a web browser, not an app.

quick question. its been a while but the patched LGUP recognizes the phone when connected normally , but when in download mode it doesn't detect it at all. can you clarify what i need to do to get that to work. read all over your instructions and also #193, and other post(s) but still can't get it to detect?? help. I'm on time crunch to mail back this phone to VZ... so thanks in advance for your help
.. i managed to get US99810d installed via lgup. when i went through and tried the adb commands the phone says that i need to enable oem unlock when rebooted into bootloader but ...inside the developer option of the phone the option to enable oem unlock is greyed out. so it doesn't let me proceed further.. can't command the oem lock..???

It's a communication issue between LGUP and the phone.
- Sometimes changing to different USB port help.
- Also reinstalling drivers, rebooting the computer.
- Sometimes changing to different version of Dev Patched LGUP helps. But if you are already on stock Pie then you need the version (called dual mode) that works with stock Pie. However there is an older Dev Patched LGUP version we used for Oreo that the T-Mobile H932 users still need for one step in their rooting process; the newer "Pie" (dual mode) version doesn't work for that step.
i managed through this... but do you know why when i use the adb commands the phone says that i need to enable oem unlock when rebooted into bootloader but ...inside the developer option of the newly installed nougat , the phone the option to enable oem unlock is greyed out and will not let me change the option??. so it doesn't let me proceed further.. .??
to expand on this, i've now loaded 4 versions of (2 us99810c us99810d , 2 us99820a us99820h) and all four has the "enable oem unlock" is greyed out...message says "bootloader is already unlocked"... ??? this will not let me enter and command
fastboot oem lock...please help...

184WTF Bootloader Unlock, TWRP Install and Root
READ in Web Browser, NOT an app!
Do NOT try this with T-mobile H932. You will brick your phone. H932 has different RSA encryption from any other V30 variant. To root T-Mobile H932 V30/V30+, go HERE.
Unlocking bootloader/rooting your LG V30/V30+/V30S does NOT remove any LG stock firmware features. Very common question due to Sony phones. This is not a Sony phone.
WTF V30/V30+/V30S Bootloader Unlock and Root
(For Every Variant EXCEPT T-Mobile H932)
1) fastboot flash commands
2) LG Oreo firmware with the bootloader unlock exploit. (Pre-July 2018 Android security patch firmware; don't worry, we can get you there.)
That's a WINNING combination.
Here's what we will be doing:
It's not complex. Will take you 20 minutes IF you're prepared with all necessary files downloaded.
* Convert to model with early Oreo and fastboot flash commands, if you don't already have that. (Pre-July 2018 Oreo firmware; don't worry, we can get you there.)
* Flash bootloader unlock code.
* Install TWRP. Confirm TWRP is installed.
* Flash "no encryption" file and "no check root" file.
* Root.
* Done.
The instructions are detailed, but the procedure isn't complex, really. (See Section 7 for trouble-shooting tips, if you need them.)
_______
US998 and all H930* variants on early Oreo have fastboot flash commands and bootloader unlock flaw. (With pre-July 2018 security patch firmware; don't worry, we can get you there.) At present, if you have post-July 2018 Android firmware, you can temporarily downgrade to unlock your bootloader.
That's why you need to convert your V30/V30+/V30S to early Oreo on one of those models,IF it's not already one. North American variants V30/V30+/V30S would use US998 Oreo, while the rest of the world V30/V30+ would use H930 or H930DS Oreo.
The rest of this post tells you how to do that, provides the tools and answers all your questions. PRINT OUT AND READ SEVERAL TIMES.
FAQ on V30 CUSTOM ROMs < READ, then come back here.
________
All credit goes to @TxanMoe who accidentally discovered this bootloader unlock exploit. He shared it with us, shot a video explaining. He started out with an AT&T H931, ended up with bootloader unlocked, rooted US998.
He found the LG Oreo update to V30/V30+ has an XDA-friendly exploit which allows easy bootloader unlock and root for MOST V30/V30+/V30S variants. LG has now patched this, but you can temporarily downgrade to earlier Oreo firmware.
(actual screenshot from @TxanMoe's video)
Even though it's fairly simple process (just flash fake bootloader unlock.bin file), there were requests for someone to write up the exact steps. Here you go.
Thank you also to @Wotta whose bootloader unlock and root guide I cribbed a lot of steps from. Please go to that link and thank him! I am giving him full credit for that section. I changed very little. He worked very hard to create that guide.
I: INTRODUCTION
In my opinion the LG V30/V30+ ("plus" only denotes more internal memory, nothing else) was the "Best Phone of 2017".
* 2017 Galaxy Note 8 came in CLOSE second, but due to more comfortable size the V30 won.
* With 2018 Galaxy S9 and S9+, again due to Goldilocks size LG V30/V30+ is my choice -- even though the 2018 phones have newer Snapdragon.
* The end-of-2017 V30/V30+ was really what the early-2017 LG G6 SHOULD have been, which LG crippled with their stupid "regionalized" specs scheme.
* Hardware-wise with Qi wireless charging, 3.5mm headset jack, quad DAC, and microSD slot, the "V30" series has features other phones like the 2017 Google Pixels SHOULD have. (Google forbids microSD slots, but they gave up Qi wireless and headset jack for no good reason when they were an early advocate of Qi wireless; Google razzed Apple in 2016 for ditching the headset jack, yet they did the same in 2017.)
* With 1440p OLED, Qi wireless, and IP68 dust/water resistance the LG V30 is what OnePlus PRETENDS to be. All top-tier Androids (Samsung, LG, Motorola, HTC, Sony, etc.) have at least 1440p since 2014. Same with high IP ratings in recent years. OnePlus has no excuse for not having those features, IF they claim to be a premium phone.
The only negative to the V30 is LG doles out "official" bootloader unlock code to only 3 variants, via LG Developer Bootloader Unlock website. LG approved IMEI with Device ID must be submitted for official bootloader unlock.bin which can be flashed via fastboot. Also, LG doesn't honor their own promises. They never gave bootloader unlock to the Open Market US998 V30+/V30S, and the Open Market US998 V30 only has LG bootloader unlock through hacking the dropdown menu of the website.
HOWEVER, @TxanMoe discovered that with the early Oreo updates, all V30/V30+/V30S can now flash a fake bootloader unlock code. Then flash TWRP and root via Magisk -- just as if you had used LG's official bootloader unlock. Crazy, huh? But it works.
Starting with the July 2018 security patch, LG has blocked this exploit but you can revert to prior firmware with dev patched LGUP. HA!
________
2: WHO CAN UNLOCK THEIR BOOTLOADER/ROOT USING THIS METHOD?
Only the T-mobile H932 can not. Do NOT try it with T-mobile H932. You will brick your phone. To root T-Mobile H932 V30/V30+, go HERE.
South Korean carrier models more difficult. They can bootloader unlock and root -- but getting modem back is a couple extra steps. @bilong9 has solved the problem:
He created a separate thread for Korean variants to help others.
Everyone else with V30/V30+ can bootloader unlock, root, have working modems, and even more. I'll explain further down.
This also works with the 2018 LG V30S -- which is just another V30 variant (same code name JOAN). Needs to be on pre-July 2018 Oreo firmware, to which you downgrade.
TLDR:
For the V30/V30+, flash the fake bootloader unlock.bin file on early Oreo US998, Oreo H930* (including G, D, DS) firmware. North American variants will temporarily convert V30/V30+ to US998 (via Frankenstein method) and then do that.
* All North America variants will use pre-July 2018 Oreo US998 KDZ. (But will need to go through Frankenstein first if not already on US998.)
Do NOT try this with T-Mobile H932. You will brick your phone.
* All H930G can use pre-July 2018 H930 Oreo KDZ firmware.
* For H930D/DS, you can use your region early Oreo KDZ or pre-July 2018 H930 Oreo KDZ. India H930DS should use pre-July 2018 IND H930DS Oreo KDZ so they have have India-specific VoLTE.
* South Korean carrier variants could also use H930 KDZ but be careful with modem. (There's more instructions Korean carrier variants here, thanks to @darkidz555 and @bilong9 for their help with this.)
Here's the newest self-made unlock.bin file from @TxanMoe:
Also, I attached it to this file to this post as a zipped file. Unzip it.
________
3: PREP
- Download/install LG Mobile Drivers for Windows.
- Download/install Windows ADB to Windows. When installing, right click on the .exe and "Run as Administrator". Temporarily disable antivirus when installing. Install as close to the root of your hard drive as possible. X:\ADB where X is your hard drive.
Here are 3 different ADB installations to choose from:
If you can't get the new_unlock.bin to flash successfully, in the Section 7-Trouble Shooting Tips we will ask you to try ANOTHER ADB installation.- Enable known extensions on Windows PC. Also, make Windows Hidden Files and Folders visible.
- Download either US998 Oreo KDZ or European H930 Oreo KDZ, depending on the phone you have -- with pre-July 2018 firmware.
* North American variants (AT&T H931, Canadian H933, Sprint LS998, Verizon VS996, etc) would use pre-July 2018 US998 Oreo firmware AFTER Frankenstein.
* European H930G would use the pre-July 2018 firmware KDZ.
* Most H930D/DS would use their region's pre-July 2018 Oreo KDZ.
Alternatively, then either use the pre-July 2018 H930 Oreo KDZ or this CIS H930DS Oreo KDZ.
* India H930DS would use the pre-July 2018 IND H930DS Oreo KDZ, which has India-specific VoLTE for carriers like Jio.
* If you have a native US998 or H930 and you are not on early Oreo, you need to upgrade/downgrade to pre-July 2018 KDZ. This exploit does not work with stock Nougat or Pie.
* V30S needs pre-July 2018 Oreo KDZ. - Download current TWRP-3.2.3-7-default.img from this page. Rename it TWRP. If you've enabled known file extensions, you will really see TWRP.img. Do NOT add the ".img" -- it should already be there. If it's not, go enable "known file extensions" in Windows!
- Download @TxanMoe unlock.bin from this link or use the zipped file attached to this post. Unzip it, of course. This is the MAGIC.
- Download attached Magisk 18.0
- Download @Zackptg5 Disable_Dm-Verity_ForceEncrypt_08.18.2019 (encryption disabler), or use attached file.
- Download @JohnFawkes AnyKernel 3 RCTD Remover (root checker disabler), or use attached file.
(Put these last three on microSD card if you have one. If you don't, then drag these files over from PC later in TWRP and flash them as instructed below.)
___________
4: WHAT'S NEXT?
* If you have US998 or any H930 variant, are on pre-July 2018 Oreo already, then go to Section 5.
* If you have US998 or H930, are on Nougat or Pie, then you need to use Dev Patched LGUP (attached to post #1 of both the US998 and H930 Oreo KDZ threads) to update/downgrade to pre-July 2018 Oreo. Then go to Section 5.
* If you have any other North American variant than US998, then use the Frankenstein method to convert to Oreo 20a or 20b US998. (You can update to newer firmware after unlocking bootloader.)
Read that Frankenstein post carefully; you have to flash to Nougat US998 first, THEN to Oreo US998. You should NOT avoid those steps. That post is my documentation for converting LS998 V30+ to US998 V30+. Adapt to your model.
After completing that, then go to Section 5.
* If you have European H930G just use LGUP to convert to Open Market H930 with pre-July 2018 Oreo KDZ. Now go to Section 5.
NOTE: All H930 variants have fastboot flash commands. But you still need pre-July 2018 firmware. H930D/DS users will still have dual SIM functionality even on Open Market H930 Oreo KDZ.
However, India H930DS users should use [STOCK][OREO]LG V30+ IND H930DS 20b KDZ for India carrier VoLTE. This version of firmware is safe, as it pre-July 2018 security patch. You can upgrade to newer firmware later after bootloader unlock.
__________
5: LET'S GO -- UNLOCK BOOTLOADER
Confirm you’re in developer mode. If Settings doesn’t show Developer Options, go to Settings/About Phone/Software Info, click Build number 7 times.
As per the LG Dev page, confirm Developer Options “OEM Unlock” and “USB Debugging” are enabled.
Connect to USB and switch to Photo Transfer Mode. (If you’re a normal user, you probably default to USB. You need Photo.) A prompt will appear on your phone to ask you to accept this PC to be authorized for USB Debugging.
On your PC, copy the new_unlock.bin you downloaded into your Android development tools directory (in my screenshots, sdk\platform-tools).
Next open command window inside that folder.
Inside that command window, run (type and hit enter):
adb devices
to ensure the device (and only the device) is listed. If it’s not listed, verify that Photo Transfer mode. Sometimes you will need to do this step again, to ensure it eventually shows your device.
(This screenshot by @Wotta shows flashing unlock.bin. But you will really be flashing new_unlock.bin.)
Reboot phone into Fastboot mode
adb reboot bootloader
You should hear the Windows sounds of USB devices going and coming. And the phone has an odd screen.
From the same directory (Android tools),
fastboot flash unlock new_unlock.bin
THIS IS IT. This should take only a few seconds to run, but on one phone I rooted took three minutes. Be patient.
Reboot with: fastboot reboot
You will now get entirely different start-up screens than normal -- it shows a warning that your device cannot be checked for corruption. (and a reference to http://g.co/ABH) This is just the "bootloader unlock warning" screen. It's just a scary picture LG shows you as the phone boots to discourage you from unlocking your bootloader. Ignore it. It will NOT prevent you from doing anything.
Your phone has now been hard reset.
Now your phone has been wiped, so you need to go through the initial phone setup options, to get to Android. Switch USB to Photo Transfer again.
You can verify that it’s unlocked either from the Developer Options – OEM Unlock is no longer available because it’s already unlocked, or by verifying Unlocked with getvar
(In a few days, the OEM Unlock option will be available again. It's just greyed out immediately after this process.)
________
6: INSTALLING TWRP AND ROOTING
Installing TWRP:
1. Switch to developer mode, USB debugging. (OEM Unlock is now not selectable right now, greyed out. In a few days it will again be selectable.)
2. Switch USB to Photo again; default is charging.
3. As before, on your PC from the Android tools directory,
adb reboot bootloader
4. Fastboot flash recovery TWRP.img (Remember you re-named this file to just TWRP.img earlier.)
(Thanks to @tech_infinity for this recent screenshot. February 2020.)
Do NOT reboot your phone after flashing TWRP! Instead, immediately boot to TWRP by using this command: fastboot boot TWRP.img
Ignore the bootloader unlock warning, which is your new splash screen. Eventually you will boot into TWRP.
6. INITIAL TWRP ACTIONS!
a. At the bottom of the screen, immediately swipe to allow modifications. Do NOT leave read-only, TWRP NEEDS to be able to make changes to your system.
b. Back up the system. This isn’t essential, but you’d be silly not to. (Has saved more than one person.) Select “back up”.
c. Select the microSD card for backup (or USB OTG).
d. Back it up. This will take about 10 minutes if written to micro SD card.
e. Do NOT install the TWRP "app" if offered.
7. MORE TWRP ACTIONS - Now turn off data encryption and install essential items… all in TWRP:
(This is not a "menu" in TWRP, it's merely a list of what you NEED to do before booting to the OS)
a. Wipe Data – Factory Reset
b. Install – set storage to the External SD (if you have a microSD card) OR drag necessary files over from PC once in TWRP.
c. Install the Magisk zip. (This is to give the encryption disabler root privileges)
d. Install the Disable_Dm-Verity_ForceEncrypt_08.18.2019 (encryption disabler).
e. Install the AnyKernel 3 RCTD Remover (root checker disabler); this disables LG's firmware root checks, which may impede performance.
f. FORMAT DATA (Select WIPE, then FORMAT DATA, then select yes.)
Do NOT delete your OS, but you do need to FORMAT your data , not just "wipe" it this time. Otherwise you may get an encryption error when you boot up the first time. If you get any red mount errors, go back to the TWRP reboot menu and select reboot to recovery and try to FORMAT DATA again. Then, after successfully formatting...
g. Reboot – "Reboot Recovery" from TWRP reboot menu (choose to reboot to Recovery). Now that the data partition has been formatted, TWRP needs to reload the recovery partition for usage. If you skip this step, when Magisk is installed again below, it may think that /data is still encrypted and set "preserve force encryption". This is also a good sanity check that LG encryption has been removed from /data.
h. Re-flash the Magisk zip again. (This is to make sure, due to Pie changes.)
i. Reboot – to System (NOW you are finally rebooting your phone! Until now this whole section has been done within TWRP.)
(Thanks to @jdgesmlls for helping to re-write that previous section to clarify better. Also thanks to @downwiththebanksters for giving the entire post a thorough inspection to clarify/explain various points better.)
If booting fails with an encryption error, did you format (f above) the partition? If not, reinstall TWRP and go through the steps again.
You will now have a factory reset phone, and have to set up the phone again, but should have root (via Magisk.)
STRONG SUGGESTION: After successfully doing all this, when you finally boot to LG Oreo, install THIS app to easily facilitate rebooting to TWRP recovery in the future: NOXX Advanced Power Menu
Also, please make another TWRP backup.
TLDR:
* flash twrp: fastboot flash TWRP.img (TWRP-3.2.3-7-default.img re-named as just "TWRP.img")
* boot twrp: fastboot boot TWRP.img (TWRP-3.2.3-7-default.img re-named as just "TWRP.img")
* swipe to allow modifications (do NOT leave read-only, TWRP NEEDS to be able to make changes to your system.)
* select WIPE data
* wipe caches
* flash Magisk
* flash encryption disabler
* flash root check disabler
* FORMAT DATA, type yes
* reboot to TWRP
* re-flash Magisk
* reboot to system

7: TROUBLE SHOOTING
MOST people have no problems. If you do, look through this list.
1) You can't flash the new-unlock.bin code.
Look at your current "About Phone". You want to confirm you're on early Oreo with pre-July 2018 security patch firmware.
Example: For any North American variant you Frankensteined, ensure you are on US998 Oreo 20a or 20b (pre-July 2018) firmware.
2) If you can't flash the new_unlock.bin code or you can't flash TWRP.
* Look in your ADB folder on your PC and confirm all known Windows file extensions enabled.
* Confirm all Windows hidden files and folders are visible.
If that doesn't help, try this:
3) Confirm USB debugging is on in Developer Options, and your PC has authorization for your phone.
4) Install another version of ADB. Install as close to the root of your hard drive as possible. X:\ADB where X is your hard drive.
5) Re-install LG mobile drivers.
6) Try another USB cable.
7) Installing this Windows driver found attached to this post. (Thanks @gazzacbr and @FZZF.)
8) Install Google USB driver. (Thanks @s0lidsneak.)
9) Or try another USB port on your computer or try cheap USB 2.0 hub
10) Error message "too many links"? Install this bat file.
11) Reboot the computer.
12) Try another computer. (THIS usually solves the problem. Kudos if you find an an old Win7 PC.)
13) Master Reset (full reset of phone using hardware buttons). Phone will be reset anyway after bootloader unlock. Doing it prior may fix something preventing the command from working.

8: SETTINGS
I know everyone has their own settings, but for new owners who want a reference point for all the various submenus and customization, I'll share screenshots of my settings. You can always change to what you like.

9: EXTRAS - MODEMS, RESTORING VARIANT FIRMWARE, UPDATES TO LATEST FIRMWARE
If you now have bootloader unlocked, rooted "US998" (either native or other North America variant converted) you will now have these bands:
http://www.lg.com/us/cell-phones/lg-US998-Unlocked-v30
US998
CDMA: 800 MHz CDMA
2G GSM: 850/900/1800/1900 MHz
3G UMTS (HSPA):850/900/1900/2100 MHz
4G LTE Bands: 1/2/3/4/5/7/12(17)/13/20/25/66
Frankenstein changes everything for North American phones, including bands.
Whereas, if you have native "EU H930", you have these bands below. Flashing any H930 variant to other H930 variant does NOT change bands for those variants, it only changes firmware.
EU H930
2G GSM: 900 / 1800 / 1900
3G (HSPA): 850 / 900 / 1900 / 2100
4G LTE: 1/2/3/4/5/8/12/17/20/28/38
REPEAT: if H930DS you will have your same H930DS modem bands even though you are on EU H930 firmware.
__________
UPDATE H930, US998, H930DS with latest stock firmware TWRP-flashable "ROMs"
After using early Oreo firmware to bootloader unlock, install TWRP and root, you can now update to latest Pie or last stable Oreo firmware by flashing these zips in TWRP:
Do NOT crossflash any North America variants like US998 with any stock H930* firmware!
__________
You would want to use these carrier-branded stock firmware TWRP-flashable "ROMs" below if the variant you need has bands or features that the "converted" US998 phone does not. NO, you cannot flash T-mobile modem over any of these. T-mobile modem partition has different RSA encryption. But you can flash other modems.
For Verizon customers, download and install @JohnFawkes's TWRP-flashable stock "ROM", based on latest VS996 Pie KDZ to get Verizon voice mail, VoLTE and Wi-Fi calling.
After flashing it in TWRP, then just re-install Magisk. Debloat with Titanium backup.
________
For AT&T customers ONLY, download and install @david.542569's TWRP-flashable stock "ROM", based on recent H931 Oreo firmware to get AT&T Wi-Fi calling and video calling. (There is no Pie TWRP-flashable zip and probably never will be.)
After flashing it in TWRP, then just re-install Magisk.
H931 owners: If you are NOT on AT&T network, then stay on US998 firmware! AT&T firmware is ONLY for AT&T users.
________
For Sprint customers ONLY, download and install @JohnFawkes's TWRP-flashable stock "ROM", based on Oreo LS998 firmware to get the extra Sprint LTE bands back. (LS998 never got Pie from Sprint/LG.)
After flashing it in TWRP, then just re-install Magisk. Debloat with Titanium Backup.
Also, more Sprint resources here. Thread created by @JWnSC, for Sprint users. Some information may be outdated due to the newer TWRP-flashable ROM above, but still may help answer other questions.

Korean variants should follow these instructions by @darkidz555.
@bilong9 has made a helpful video for Korean carrier variants:

Read more in this thread for the Korean carrier models, created by @darkidz555.
Here's a TWRP-flashable zip "ROM" for Korean variants, thanks to @koo04034.
@bilong9 update to Korean Pie.

9A: EXTRAS -- LG V30 Unlocked Bootloader Warning Disabler
When you unlock your bootloader, LG throws a "scary" warning picture at you every time you reboot your phone:
It doesn't hurt anything, but it can be annoying. If you want to get rid of it, keep reading.
This was a TWRP-flashable zip file from ROM Dev Aeronliru, a.k.a. AeronLee:
=======
Unlocked Bootloader Warning Disabler
Compatible with H930, H930D, H930DS, V300, H933, US998, LS998, VS996, H931, T-Mobile H932 with both Pie & Oreo firmwares. CHECKED!
=======
There was a dedicated thread for this mod. The developer asked me to post it to help people -- but then he left the community and then he asked me to remove it. I did.
However, someone found you could still access the original post with downloadable zip attachment in the Internet Wayback Machine (which shows historical posts). < That is the post where it's discussed in that thread. If you click on the link in that discussion, you should see the original post with attachment. (You may need to disable any VPN to access the historical thread in the Wayback Machine.)
I am still honoring the Dev's request, as I indeed removed the attachment -- but if people can still access it in other ways I can't stop them. All credit for this mod goes to genius Aeronliru, a.k.a. AeronLee.103(WTF...!) LG V30/V30+/V30S Bootloader Unlock & Root Method (With Clear Instructions)

Thank you for supported
Sorry for my English27EDIT: ignore these next few pages of posts. We were all trying to figure this all out. It was crazy stuff, and initially @TxanMoe did brick his phone. But he recovered, and we figured out what worked and what didn't.
Skip to post #56 for the first success story replicating this method. After that, it was off to the races!
Everything after post #56 on is relevant, while everything between here and there is not really worth reading, as there was lots of false speculation proved wrong.
We figured out LG Oreo has a great bootloader unlock flaw that can be exploited so we can install TWRP and root. Also since the initial post @TxanMoe perfected the "fake" bootloader unlock.bin code. (Originally he used a Huawai M8 unlock code -- from an LG G4 thread. Crazy stuff.)
Post #193 has the full instructions, as does the op above.
POST #56
Your the man! Followed your exact steps. It worked. I now have twrp and unlocked bootloader on my ls998(converted to us998). Thanks for this

(back to original post #2)
I actually don't see an LG G4 unlock.bin in that thread. I see someone asking for one. Somebody supplied one from an M8, but I don't see one from an LG G4. OR if they did, they edited off, back in 2015. So, where did you find it? Which post?
But good luck to you, if this is true. You definitely have everyone's attention!12EDITED:
