I just bought an LS998 flashed to US998 firmware. It's not possible to get OTA or Bridge updates so I wonder what would be the best/safest way to upgrade to Oreo stock rom.
I have no interest in rooting or moding. Just stock ROM.
Thanks.

Flash latest US998 KDZ (firmware image) with LGUP. Current latest is US998 20H Oreo. In LGUP, you can use "Upgrade" mode and keep all data. If that doesn't work for some reason, then use LGUP "Refurbish" mode, which will still update the firmware but will super duper factory reset the phone.
LGUP is attached to every KDZ thread I maintain, along with installation instructions.
Here's the US998 KDZ thread:

Thanks. Let you know how it goes.
I picked up a new in box factory unlocked LG V30+ (LG-US998) on Amazon pretty cheap in December. What I didn't realize it that it is just running android 7.1.2 not 8 which I believe is the most current version available. I bought the unlocked version to avoid all the AT&T bloatware, but now I'm realizing it won't update OTA to the newest OS and is probably behind on security updates. Does anyone know what I need to do to get the phone to update OTA. I'm not interested in a custom rom or any of that, so if that means I need to flash the AT&T stock rom (with their bloatware) that's fine. I just want the phone to get OTA updates. I tried using the LG software to update it and it doesn't recognize the phone.
Refer to these two threads. Read through them, ignore the part about rooting if you won't be doing that.

You just need to update to latest US998 KDZ via software called LGUP.
See link below. You want steps 4 and 5.
FRANKENSTEIN INSTRUCTIONS
https://forum.xda-developers.com/showpost.php?p=76510671&postcount=168
Yes, those instructions are for converting to US998 -- but steps 4 and 5 still apply to someone just wanting to update US998 to most current firmware.
Install LGUP, download latest US998 KDZ (links provided), flash via Update mode. Easy.

I read through but I'm a bit unsure of what I need to do. Do I need to unlock the bootloader or root it? I'm not interested in rooting it. Do I just download US99820h_00_0318.kdz and use the patched LGUP to install / flash it to my phone? I'm not sure where to get the proper patched version of LGUP to do this.

Yes, that's exactly what you do. It's like a manual OTA. You have the file, you use Upgrade mode with Dev Patched LGUP (which is more powerful than stock LGUP).

I had this same issue with my phone... Wouldn't ever get OTA updates... Honestly, the easiest way to get updates outside the kdz and lgup is to use the twrp stock builds. They're stock V30, you can get them without bloatware (US-998), and updating them is a piece of cake once you know what you're doing... In my case, the lack of updates seemed to have something to do with the fact that my device was somehow a Sprint device, blah blah blah....
Anyways, TWRP stock builds is the way to go... I'm currently running the Tmobile stock build and it's fine and does whatever I need it to... I like it better than custom

But they don't want to unlock bootloader and root, so I'm telling them the easy LGUP Upgrade mode method with latest US998 KDZ.
I agree TWRP flashable zip is fantastic. I use it, but for my wife's phone which is not bootloader unlocked or rooted (and my sister's phone also), the LGUP/KDZ method is where they need.

I hate to resurrect such an old post, but I never got around to doing this. Now that the quarantine is in place I have time. Is there a newer version of the kdz that I should use (probably Pie)? I'm guessing there's a newer version of LGUP (modified) as well?
Let me make sure I understand this too. I can use the modified version of LGUP to flash the newer kdz to my phone using the "upgrade" option and it keeps all the data currently on my phone, right? If later I wanted to do a factory reset on my phone, that would wipe the data but still retain the newer kdz that was installed, correct?

For US998, I only recommend updating to last Oreo 20h. I'm rooted, still on that. My wife, mother, sister, brother in law who are all NOT Bootloader Unlocked/Rooted are all still on that, also.
The one US998 Pie KDZ we received is very wonky. It's technically for U.S. Cellular. LG never released Pie KDZ for Open Market. Charging is slower, other things broken if you use other carriers.
Many people find it hard to update to, and if you have problems most of the workarounds depend on having TWRP.
I strongly recommend stable last Oreo 20h.
Yes, there is newer version of Dev Patched LGUP. I have it posted in the US998 Oreo and Pie KDZ threads, as well as Frankenstein.
Yes, if the use Upgrade mode you keep your data as long as you are already on earlier same firmware, in this case US998.
I have a stock US998 V30+ that is currently on Nougat. I am wanting to use LGUP to update to the latest version of stock Oreo. I am new to rooting and custom Android firmware, so I have a couple of questions about backups and firmware before I take the plunge.
1. I will probably eventually go to a custom firmware, but I would like to stay on stock right now. My plan is to upgrade to the most current version of Oreo through LGUP, create a backup there, downgrade to pre-July 2018 Oreo to unlock the bootloader and root, and then finally restore my backup of current stock Oreo. Would this allow me to root my phone and get the latest version of stock Oreo without losing my current phone data and apps?
2. Can I flash straight from Nougat to Oreo 20h? I saw in this post that it is recommended to flash 20e-20h individually through TWRP after root, but I wasn't sure if that applied to upgrading directly to 20h through LGUP.
3. Is it possible for me to create a full system backup of my Oreo install on stock before I root? I would essentially like to take an image of my OS and reload it after I root and wipe my phone.
Thanks in advance!

For bootloader, no need to update from Nougat to LATEST Oreo (20h), to then have to DOWNGRADE back to what you (temporarily) need for bootloader unlock and root (20a or 20b). Instead update to what you need for bootloader unlock and root (US998 20a or 20b), THEN update to 20h afterwards.

You can flash straight to Oreo 20h from Nougat, but if you need 20a or 20b FIRST for bootloader unlock, why would you waste effort doing it? That's having to backtrack.

Not before you root, no. That's something like TWRP or Titanium Backup does. When you unlock your bootloader your phone will be Hard Reset. Even AFTER that, you will purposely re-format your entire Data partition as part of the TWRP installation steps.
Having said that, Google DOES make backups of your apps and settings (if you have that option enabled) in the Cloud, and when you switch phones or make major updates like this (which is essentially a "new" phone), Android asks if you wish to "restore" the most recent history of apps and settings if possible. Say yes, have a good Wi-Fi connection, sit back and relax -- and all your apps and settings will restore.
After you go through all this, in TWRP yes you can then make a backup (RECOMMENDED!) for future use. In fact, you should always have a recent backup stored, just in case. You can also use Titanium Backup to make backups of all apps and data.

Ok that makes more sense. Thank you for clearing that up. My main reason for the suggestion about backtracking was because I thought that it might allow me to keep my current setup and data if I was already on Oreo to make a backup before unlocking the bootloader. It appears that won't be an option though.
Does flashing a stock kdz through LGUP without rooting format the device?

Depends on which LGUP option you use. Upgrade keeps data. Refurbish or Partition DL of all partitions does not. There are times you HAVE to do that.
You can plug in your phone to PC and transfer off any files you wish -- music, pictures, video, etc. Save as much stuff as you can, then transfer back later.

I have a US998 running the latest Verizon Oreo 20k. It tried to update to Pie but failed and since then, I've lost all fastboot commands. Prior to this, I had TWRP, and an unlocked bootloader. Now, it seems by bootloader is locked, and I cant get into download mode and downgrade with any .kdz via LGUP. Any suggestions?

You never had no fastboot flash commands while on Verizon firmware. You only have fastboot flash commands while on US998 firmware. That's why you had to temporarily Frankenstein to US998 to unlock the bootloader.
Why did you try to update to Pie OTA while you had TWRP custom recovery? OTA is ONLY for phones with full stock. We tell people over and over they will NEVER take OTA unless back in on full stock firmware.
Most people with TWRP freeze or disable the annoying OTA bags which are useless to them.
You should have waited for the TWRP-flashable zip that's coming...
Yeah, hindsight is 20-20. I installed stock 20k Verizon firmware, and took the OTA update. Wanted to play with Verizon's Pie for a bit. The update downloaded, but on rebooting, it failed. So now I'm still stuck on Verizon Oreo, no fastboot commands, unable to use LGUP to flash any .kdz. Lesson learned. Perhaps the guy on ebay can remote fix this.

You didn't install full stock firmware if you flashed with VS996 TWRP-flashable zip.
If you flashed full VS996 KDZ via Dev Patched LGUP, then yes that's installing stock firmware. And that would have wiped out TWRP, and safety allowed you to update with OTA.
HOWEVER, you would have no fastboot flash commands and no way to reinstall TWRP. You would then have to Frankenstein back to US998 for that.
Good news is your bootloader is still unlocked. You never locked it back. You just have no fastboot flash commands.
You've tried to manually go into download mode before opening Dev Patched LGUP?. Just asking.
(My hindsight isn't 20/20. I could have told you this would have happened if you'd ask questions. We tell people over and over not to try to take OTA after they install TWRP.
1) We have something better than crappy partial image OTA. We have full image KDZ and then TWRP flashable zips based on full image KDZ.
2) They will mess up their phones taking OTA with TWRP custom recovery installed. I'm sorry you didn't read the warnings.)
I don;t think anyone could predict that an OTA would wipe out download mode. Plenty have taken the Pie update without this happening. For ****s and giggles, I wanted to try Pie, and for me, the best way to do so was to do it via OTA on a fresh stock kdz. I didn't mind, as I can (could) easily get TWRP, root,etc back. However, the OTA didn't install (Verizon's fault?), there was an update installation error. I gave up, tried to kdz back to us998 like I've done successfully a bunch of times. But LGUP can't install any kdz because I lost download mode. It just gets to 4% and reboots back into the OS. I have a feeling my LAF is corrupted. Taking an OTA from Verizon that is meant for millions of phones shouldn't cause this sort of trouble but it did. I lost my ability to revert changes.
It appears the only way to get download mode back is to do it remotely via test points. Arghh.

So you did flash full VS996 Oreo KDZ? You had already gotten rid of TWRP prior to taking the OTA? I thought you had flashed V996 Oreo TWRP flashable zip and tried to take OTA with TWRP custom recovery still installed.
Then other than the crappy partial image OTA, I don't know why it didn't work.
Are you able to go into download mode manually before opening LGUP? If so, what I would suggest is re-installing Verizon Oreo KDZ via Refurbish mode to clean things up. Make sure you are using the NEW Dev Patched LGUP found in the Pie KDZ threads, not the older one found in the Oreo KDZ threads. The older one doesn't work to downgrade from Pie. Even though you didn't successfully update to Pie, something about your system may have changed.
Then after successfully reinstalling VS996 Oreo KDZ (if successful), then go full blown Frankenstein to US998: US998 Nougat, Master Reset, US998 Oreo.

See that thread. They recovered.
Unfortunately, I have somehow lost download mode, so LGUP will never work. Is it possible for an OTA to inactivate download mode? If so, that seems pretty shady, but not unlike Verizon. If Verizon is inactivating download mode, they're being selective (maybe by IMEI?) sonas not to be obvious about it.
From what I understand, the LAF partition is associated with download mode in LG phones, is it somehow possible to restore via LGUP an LAF image or whatever format that's in and maybe get LAF partition back?

I have an AT&T V30 that is unlocked and running US99820E, and I am trying to flash the Verizon PIE FW (VS99630c_00_0902_ARB00) via LG UP. I have tried using the refurbish, upgrade, board DL, and partition DL options in LG UP.
After I flash the Verizon FW, when the V30 restarts it stays at the Verizon logo with the four dots.
I can flash back to the US998 FW via LG UP, but I can't get the Verizon Pie FW to work.

You have to use Frankenstein method to cross flash North American variants when using full image KDZ.
(And even Frankenstein does not allow T-mobile H932, due to different RSA encryption.)
You can't just cross flash Oreo and Pie KDZ back and forth. There's a method you have to use, where you first flash Nougat of that new variant, Master Reset (not Factory Reset) -- then you can update from there. That's how you got from AT&T firmware to US998 in the first place, right?
See the Frankenstein instructions.
Yes, it's different if you're using TWRP flashable zips to cross flash.

You have to use Frankenstein method to cross flashing North American variants when using full image KDZ.
(And even Frankenstein does not allow T-mobile H932, due to different RSA encryption.)
You can't ust cross flash KDZ back and forth. There's a method you have to use, where you first flash Nougat of that new variant, Master Reset (not Factory Reset) -- then you can update from there. That's how you got from AT&T firmware to US998 in the first place, right?
See the Frankenstein instructions.

Thanks for the reply, ChazzMatt!
At what point in the process would I flash the Verizon Pie KDZ? Would it be after Step 4, flashing the Oreo US998 in Upgrade Mode? And do I flash the VZW Pie KDZ in Upgrade or Partition DL?

1) From US998 Oreo (you're on that right now, correct?), flash VS996 Nougat via Dev Patched LGUP in Partition DL mode.
2) Master Reset (which is not Factory Reset).
3) Then flash VS996 Pie in Partition DL mode. (Upgrade mode might work. But try Partition DL mode first.)

Alternatively if you had unlocked bootloader and have TWRP custom recovery, then you could install the VS996 Pie TWRP flashable zip straight from US998 Oreo.

Are you a Verizon customer? Is this why you want VS996 firmware? You have an already-activated Verizon SIM card?
Anyone resolved this?
I am having the same problem. Just switched from AT&T to Verizon. I followed the Frankenstein method (1. Flashed VS996 Nougat, 2. Master Reset, and 3. Flashed Pie using both Refurbish and Partition DL mode); both gave me the same result. After the red Hello, I get the Verizon with four animating dots @ full screen brightness. I let it sits for 30 minutes and nothing happen. I repeated the steps above and replaced step 3 with Oreo and it works fine. Then I perform an OTA update. Update 13 was applied okay, but Update 14 included Pie and after installing the update and reboot; it is stuck on the Verizon screen again. I also tried US998 Pie and it had the same problem.
Anyone has any idea on how to fit it?
