There's a thread for Korean models and they discuss how to get the Korean modem back after bootloader unlock and root.
Korean variant bootloader unlock and root.
THIS THREAD IS FOR KOREAN VARIANT LG V30 TO GET THE SIGNAL MODEL SUPPORTED : V300S, V300L V300K FOLLOW THE GUIDE BELOW AND DONT MESS UP. DONT DO ANY EXTRA STEP THAT IS NOT MENTION HERE. WE WILL NOT HOLD ANY RESPONSIBLE IF YOUR DEVICE GO...
Hope that helps. I don't have time right now to go through the thread to see the exact post. I know some of the links in that thread post #1 appear dead -- but most of them were just mirrors to MY posts, in my ChazzMatt Android File Host account. You can find most of them there if you look.

@osprey, who made this? Would like to give credit. Since adopting two school age children end of last year, I haven't had much time to peruse the Telegram group. I know JohnFawkes retired from most dev work, but at least they were nice enough to admit it was built on his work.
I'm on XDA about once or twice a week right now.
I wasn't sure, or else I would've given credit, myself. I guess that his name is "ɐoɔɐɾ". I didn't realize that that was a username until now, but I'll edit my post to give him credit.

Help me ):, my lg v30 may brick. When i flash us99830b from Twrp then flash magisk and reboot (I has been wipe data, cache before). Now, my devices is still lock at logo, when I back to twrp its lost, when I come to download mode its just waiting for any devices connection.....my devices manger just show USB port com3. What should i do? )""":
is the variety of V30 you have compatible? Check the WTF thread.
Hi all,
I have a quick question/issue which looks like no on else has using this rom. I have the US990 and ran stock Oreo for the longest time. I decided to update to pie so my work profile would be supported. At the about same time, I decided to switch to ting (using the T-Mobile towers). My current issue now is GPS is some what inaccurate. In Google maps, it sometimes is able to find my location but in actually using it for directions from current location to a destination, it says gpa is not available. I guess I'm trying to figure out is it is due to the pie update or if it is due to ting. I have the high acceracy setting enabled and all. If anyone has insight, be much appreciated (as my current thought process is either force flashing back down to Oreo (which I see may not be quite possible or smart) or try updating to 10...orrrrr try another budget carrier).
Edit, forgot to mentioni also tried Waze with still no gps.

Are you rooted with magisk?
If so look up the Global Optimized GPS File Replacer V3 (Revival) module.. might do what you need

35RECOVERY TIPS if you get stuck on logo while updating to this wonky US998 Pie. < Please stop asking in Telegram thread or creating new XDA threads when it's right here. We will just direct you back here. OK?
____________
* Do NOT update to Pie yet if you wish to unlock bootloader in order to root.
For bootloader unlock purposes, use the US998 Oreo KDZ versions with no later than July 2018 security patch: 20a or 20b.
Look at the names for dates in the title in that thread link. AFTER you unlock bootloader, then you can update to newer firmware (like this Pie). Flashing a newer KDZ (like to Pie) will not re-lock your bootloader.
With unlocked bootloader, then on Pie KDZ you can install TWRP and root.
Stable TWRP 3.3.1 is recommended by our TWRP dev for Pie.
To install TWRP (or re-install TWRP on bootloader unlocked Pie) and root, PLEASE follow these instructions for success!
* If you've already updated to Pie with locked bootloader, see post #3 for instructions on how to downgrade to earlier Oreo firmware to first unlock bootloader. Or downgrade back to most recent Oreo because you decided you don't like Pie.
* If you have no desire to unlock bootloader or your bootloader is already unlocked, see full image KDZ and KDZ-based TWRP-flashable zips below.
* ALSO do NOT update to LG stock Pie yet if you wish to run LOS-16 "Pie" custom ROMs -- at least for now. See REASON HERE. Stock Pie update conflicts with LOS-16 Pie, even if you downgrade back to stock Oreo. After stock Pie update, your phone has been permanently changed/degraded when going back to Oreo for custom ROMs. Using Permissive kernel can overcome some of those issues, but you have been warned.
Whereas you do need to update to stock Pie first as a foundation before trying to install "Android 10" LOS-17 custom ROMs. However, those ROMs are still unfinished work in progress -- so if you don't like them and want to go back to the older stable LOS-16 "Pie" custom ROMs, then you've totally ignored the warning above. Again, stock Pie makes permanent changes.
NOTE: After installing Pie, if you get weird lag,
* try this fix. Just make a backup in LG Bridge. Nothing else. Somehow CREATING the backup (but not actually using it to restore anything) re-sets some stuff in Pie, so it acts like it should? I know it sounds strange but it works. Thanks to @thefpspower for the tip!
* OR If that doesn't work or you don't have access to PC, try this: go to Settings> Restart & Reset> Reset App Preferences. Thanks to @HoussiLAM for that tip. Both may do the exact same thing, I've not experimented to see.19NOTE:
Four workarounds. Two require unlocked bootloader. If none work for you,
1) make sure you are on the correct Dev Patched LGUP from this thread. (See post #2 for Dev Patched LGUP and follow the installation instructions. Uninstall any prior version of LGUP.)
2) Look over these steps again, make sure you followed them all. Do NOT skip steps!
If it STILL doesn't work, there are no more answers after this. Just flash back to US998 Oreo 20h wait for the next US998 Pie KDZ.

4 WORKAROUND METHODS TO SUCCESSFULLY UPDATE TO US998 PIE FOR THOSE PEOPLE GETTING STUCK ON ThinQ/ LG LOGO
_____________
METHOD #1 -- WITH OR WITHOUT UNLOCKED BOOTLOADER
I've been reading reports from other LG models (like LG G6), where LG has LG Bridge downgrade the phone back to Nougat first before then updating to Pie. LG Bridge uses full image KDZ, temporarily downloaded to PC.
So I suggest trying to Partition DL back to Nougat KDZ, Master Reset, then Partition DL to Pie KDZ. Here are the steps...
0) Using Dev Patched LGUP from this thread, REFURBISH back to US998 20h. Turn off phone, go into Download mode.
1) 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, go into Download mode.
4) Flash US998 30b Pie KDZ via Dev Patched LGUP using Partition DL mode. Select ALL partitions.
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!!
_____________
This next method by @EstebanxZ uses parts of #1 & #3 (oldest method which works). I'll will rewrite when I get time, but right now just quoting verbatim what worked for him:
METHOD #2 -- NEEDS UNLOCKED BOOTLOADER
_______
This third below is our oldest method which works, but is most complicated.
METHOD #3 -- WITH TWRP
We have a working method for people with TWRP who are having trouble getting across the line for Pie. Most people have no problems updating. I didn't. However, for those who are having issues, there's a workaround, but you need TWRP installed and make sure you're using the Dev Patched LGUP from THIS thread. (See post #2 for Dev Patched LGUP and follow the installation instructions. Uninstall any prior version of LGUP.)
For users with TWRP who get stuck on ThinQ/LG logo:
0) Using Dev Patched LGUP from this thread, REFURBISH back to US998 20h. Flash TWRP recovery via fastboot. Turn off phone, go into Download mode.
1) Flash Canada H933 10h Nougat via Dev Patched LGUP using Partition DL mode -- EXCEPT for Recovery partitions, to keep TWRP. Do NOT choose "all" partitions! Omit/UNcheck the Recovery partitions.
Reboot. You will probably have lost download mode, but you've prepped your phone, corrected any partitions -- and you still have TWRP.
____
NOTE: For the next step, you will need to use the much-hated "hardware button dance" to boot to TWRP custom recovery, since H933 firmware doesn't have fastboot flash commands to boot to TWRP from PC. You also no longer have root at this stage, so you can't use the excellent Reboot Recovery app or NOXX Advanced Power Menu app...
You will need to IMMEDIATELY start the "hardware button dance" just time phone reboots. This is the ONLY time I will ever tell you to use the "hardware button dance". Any other time, it's stupid and ridiculous and there are better ways to boot to TWRP custom recovery.
____
2) Flash US99820e TWRP-flashable zip to get back Download mode. (Remember you KEPT TWRP recovery partition!) IF it doesn't boot, make sure you are on Magisk 18.1. Oreo TWRP-flashable zips normally require Magisk 18.x.
3) Then REFURBISH to US998 20h KDZ.
This will temporarily wipe out TWRP, but give you a completely fresh install. You will still have unlocked bootloader and fastboot flash commands.
4) Now flash TWRP recovery again via fastboot flash commands and then flash the US99830b Pie TWRP-flashable zip. See Section 6 of the WTF instructions if you need to remember all the steps to install TWRP, etc.
"Phone booted immediately on pie and everything is working great." - TESTER
You are now on US998 30b Pie!
After all that you can flash to other compatible TWRP-flashable zip if you wish.

METHOD #4 -- WITH OR WITHOUT UNLOCKED BOOTLOADER
Thanks to @SaiLas:
https://forum.xda-developers.com/showpost.php?p=81499481&postcount=59317I've been reading reports from other LG models (like LG G6), where LG has LG Bridge downgrade the phone back to Nougat first before then updating to Pie. LG Bridge uses full image KDZ, temporarily downloaded to PC.
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!!

See Installation instructions for KDZ. That is your best chance of success. Then re-install TWRP after successfully updating to Pie KDZ. Your bootloader will still be unlocked. These instructions below are if you are stubborn and don't want to do that...
Flash the "ROM" with latest TWRP. Flash Magisk + @JohnFawkes AnyKernel 3 RCTD Remover (root checker disabler) immediately afterwards before rebooting to system. It's just stock KDZ but in TWRP-flashable version. Not debloated nor meant to be updated in the future. It's just a very convenient mechanism to have newer stock firmware instead of using dev patched LGUP to flash partitions, etc.
This TWRP flashable zip has the new Pie encryption disabled. No encryption enforced, but you can encrypt in TWRP if you want afterwards.
The dev recommends formatting data before installing this TWRP-flashable zip: "format data before flashing, not wipe but format". That's your decision. Others have not.
* Stable TWRP 3.3.1 is recommended by our TWRP dev for Pie.
TWRP-FLASHABLE NOTES:
If those instructions above do not work for you for some reason, then go through these full blown steps (adapted from Section 6 of WTF Instructions):
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 TWRP-flashable zip
d. Install the latest stable Magisk zip.
e. Install @JohnFawkes 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 back 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.)
STRONG SUGGESTION: After successfully doing all this, when you finally boot back to LG Pie, install an app like this to easily facilitate rebooting to TWRP recovery in the future: Recovery Reboot. Allow it root privileges when asked by Magisk and put icon shortcut on your desktop.
Also, please make another TWRP backup.

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 patched LGUP and flash PIE KDZ either via UPGRADE (to keep your data, but see Note about TWRP) or via REFURBISH or PARTITION DL. If the latter, then in the pop up box "Select All". Use the attached patched LGUP in this post.
* NOTE: YOU CAN NOT USE LGUP "UPGRADE" 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). If you have TWRP custom recovery and want to use LGUP, then use PARTITION DL OR REFURBISH which will NOT keep your data and will wipe out TWRP. Or use the TWRP-flashable zip (ROM) instead of LGUP, which will keep your data and will keep TWRP.
3) IF your bootloader is unlocked, it will remain unlocked. If it's not unlocked, then you will just be updating to Pie -- but will have to temporarily downgrade to early Oreo if you ever want to unlock bootloader for root.

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!
As mentioned before, use UPGRADE, REFURBISH or PARTITION DL modes. REFURBISH and Partition DL are probably best.
WARNING: In LGUP do NOT go messing with modes not mentioned in these instructions. Especially do NOT use Chip Erase.
I don't care what anyone else tells you. If you listen to them, let them help you recover from messing up your phone.
https://9to5lg.com/lgup-1-15-manual-how-to-unbrick-restore-your-lg-devices-with-lgup/
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.9HOW TO (temporarily) DOWNGRADE BACK TO OREO FOR BOOTLOADER UNLOCK
(or DOWNGRADE BECAUSE YOU DON'T LIKE PIE)
1) DOWNLOAD FIRMWARE AND DEV PATCHED LGUP
* Download Oreo KDZ you wish to install -- for bootloader unlock would be US998 20a or 20b.
(If you just don't like Pie, then choose the most recent Oreo KDZ in that thread, which is US998 20h at the top.)

4) IF YOU NEED TO UNLOCK BOOTLOADER (with early Oreo), GO READ WTF INSTRUCTIONS8For people who want to switch on US998 30b and have problems
METHOD #4
no difference, locked or unlocked bootloader
simple and safe, working 100% ( others didn't work for me except METHOD #3, but the download mode does not work there )
You must be on US998 firmware, no matter, NOUGAT or OREO and you needs files:
1. H93310h_00_OPEN_CA_OP_1124.kdz https://lg-firmwares.com/downloads-file/12260/H93310h_00_OPEN_CA_OP_1124
2. US99820h_00_0318.kdz https://lg-firmwares.com/downloads-file/19157/US99820h_00_0318
3. US99830b_00_0902.kdz https://lg-firmwares.com/downloads-file/20723/US99830b_00_0902
4. LGUP patched https://forum.xda-developers.com/attachment.php?attachmentid=4828349&d=1569503757
Steps:
LGUP must recognize your V30, V30+ like US998 model, if not - first flash any US998 firmware in any possible way, reopen LGUP, reboot phone, reconect usb-cab, etc
Its very important, again,
LGUP must recognize your V30 like US998 model
if Yes - do the following ( it will take about 10 minutes )
do not close LGUP and don't let phone turn on completely until the process is completed!
We do everything exactly on points
1. Flash H93310h_00_OPEN_CA_OP_1124.kdz via LGUP using Partition DL mode ( check all partitions), when phone automatically restarts - immediately do hardreset using the buttons, keep hold Vol. up button, we get download mode again
2. Flash US99820h_00_0318.kdz using REFURBISH mode, when phone automatically restarts - just wait "Erasing" screen and now immediately keep hold Vol. up button, we get download mode again
3. Flash US99830b_00_0902.kdz using UPGRADE mode ,
at this stage the phone will boot normaly and you finally get 9.0 Pie.
Next step is optional, but strongly recommended
4. Flash US99830b_00_0902.kdz again using REFURBISH mode, and now you have clearly fully stock.
Done ! Congratulations. - 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.
