It sure is, but you will need to reflash the stock rom and bootloader for your phone. Firstly you will need to find the correct kdz for you device, or use Lg bridge/ LG UP to get back to stock.
Once you have done that you can relock your device in fastboot mode using "fastboot oem lock" heres a link on how to relock just in case your not sure
http://www.mylgphones.com/re-lock-your-bootloader-on-the-eropean-lg-g5-h850-variants.html
Let me know if i can help anymore, ill try my best
Please excuse any spelling mistakes send for my LG G5
Just for info: fastboot oem lock worked also for me with latest nougat.. Thats what i did actually... No need to go back
Can confirm, "fastboot oem lock" works.
Sorry for reviving the topic (I hate it) But this model needs some updates. Hope I can help someone. This model is defective....
I was looking on the internet and everyone says to downgrade to v10c to lock oem back on G5 H850.
Well, I tried to do it with LG UP, got an error, and got stuck on Download Mode (Firmare Update screen).
I opened the LG Bridge, went to Software Update screen and them clicked on Recover Faulty Updates.
Then it worked and flashed the V20a-EUR-XX, Android 7.0 Nougat.
Went to fastboot mode, typed fastboot oem lock, and everything went to initial state... :good:
So I confirm that works on the last update (until now) V20a.
Can I relock with v20d ???
I relocked with V20a so you would assume so

will the phone still be rooted after relocking oem?

I have an unlocked LGV30 us998 that i would like to install the verizon VS99620j on it. is it possible? Will the verizon features like Visual Voicemail, Video calling, and wifi calling work?

YES, when you Frankenstein any North America phone to another, it becomes that phone.
Many Verizon customers on here are using former LS998 or US998 converted to VS996 with those full features.
However, you'll probably need an already-activated Verizon SIM card. Many US998 sold on eBay are converted LS998, and Verizon won't activate former Sprint phones even if they are now US998. Where did you get your US998?
Thanks for the reply. I forgot to mention that the unlocked V30 is activated on Verizon already. I just want to add the other features and update the os.

Yes.
When you say unlocked, you mean carrier unlocked or you've bootloader unlocked/installed TWRP/rooted?
You can get to VS996 firmware either way, but the method depends on what you have -- either flashing KDZ with Dev Patched LGUP or TWRP-flashable zips via TWRP.
It's carrier unlocked, not bootloader unlocked.

OK, then Dev Patched LGUP, flashing the latest VS996 KDZ in the VS996 KDZ thread. Use REFURBISH or Partition DL mode.
Thanks for the reply, one more question, after doing the kdz in vs996, will this also allow me to get OTA's from Verizon?

Probably not. Don't know for sure.
But very easy to use LGUP "upgrade" mode every couple of months when a new KDZ is released. Takes 5 minutes. You don't want "upgrade" mode to convert to VS996, but after that you can use it to get updates. Keeps your data -- it's like a manual OTA.
New VS996 KDZ is posted here in this forum and other sites every time it's released, which is about every couple of months.
VS99630c (30c) onto US998 with LGUP?
Does everything in this thread also apply to using Dev Patched LGUP to flash the VS99630c (30c) KDZ onto a carrier unlocked US998?
Thanks!

Yes.
To be safe, you should really flash Nougat VS996 KDZ via Partition DL mode or Refurbish mode, Master Reset, then flash Pie VS996 30C to that phone.
However since it's a VS996 and you're coming from US998, you can get by with skipping the Nougat step. But I hate telling people that, because it's only VS996/US998 which have that loophole.
All other North American variants have to go through Nougat first to cross flash -- unless they're already bootloader unlocked and rooted, in which case they can just flash the appropriate TWRP flashable zip version of that KDZ.
I have a V30+ US998 and came with Nougat US99810c. It anks for update via OTA fron US99810d. But is from AliExpress and in the logo when you turn on the phone just shows V30 and not V30+. But it has 128GB. If I update OTA will give hardbrick? What you recommend?

What does it matter if it was originally US998 V30+ or not? You said it has US998 firmware on it NOW, and you said it has 128GB internal memory. That fits the definition of US998 V30+.
To be honest, if it still has Nougat on it and V30 showing instead of V30+, that's symptoms of dealer probably Frankensteining (via Octopus box) from some other North American variant to US998 -- then not "finishing" the job to update to Oreo. But at this point in time, it's a US998 with 128GB internal memory.
All North American variants are compatible with other North American variants -- EXCEPT for T-mobile H932. Since you are already on US998 firmware, then it was previously either H931, H933, US998 (64GB), AS998, LS998, VS996 -- but doesn't matter. Maybe originally it was even 64GB US998 and they swapped in 128GB internal memory from another phone. Really doesn't matter at this point in time. You never owned that previous phone, whatever it was. You NOW have US998.
(Yes, I could tell you how to find out what the phone was originally, if it was something different -- but it's not relevant to this current discussion about updating to US998 Oreo and would only confuse you. So, let's not go there.)

Sorry about my ignorance. But in case my phone is a frankstein, what happen if I upgrade OTA? In the case, is just asking a security update. The frankstain version upgrades OTA narmally? In the case I chose to use LGUP. I have a patched LGUP (that I used to root my V20 H910 that I sold) and can be use partition DLL option? I think is more easy to use OTA, because I don't have to format my phone. In the case, can I know if is frankstein using the IMEI? OR IMEI can be modified?

If it's giving you the option of OTA for security update, you can take it. See what version you are on after that. If it gives you Oreo OTA option, you can take that.
After Nougat 10d is Oreo.
No, most Frankenstein won't give you OTA update options. So that means maybe do you have original US998, but perhaps they just did something to update internal memory to 128GB...

I did search by the IMEI and I find an interesting information. In site IMEI Pro says that my phone is the US998 Plus, but the serial number information there is different of my phone menu. I don't know if they changed the IMEI or serial number. This information is possible to say if my phone is modify? If the serial number is different, can affect the update?

Stay on 20b for right now. To unlock the US998 V30+ bootloader you need to be on 20a or 20b, to take advantage of the early Oreo bootloader unlock exploit we call "WTF".
AFTER you unlock Bootloader, install TWRP and root, you can update to most recent Oreo 20h using TWRP flashable zips.
Read the WTF instructions thoroughly. Even print them out if you can.
You're on exactly the version firmware you need right now for bootloader unlock.

You can always go back to any previous OS. BUT for bootloader unlock you need to temporarily be on early Oreo. Please read the Root Sticky.
So yeah, if you update to Pie now (I assume you mean via OTA) without first unlocking your bootloader you will have to go back to Oreo 20a or 20b to be able unlock your bootloader and root.

Not sure why your are asking about re-locking bootloader again, but for that (like I said before) you have to make sure you're on full stock KDZ. THEN relock it with fastboot commands. You can't have TWRP custom recovery when you do that.

I understood. In the case, can I go directly to Android Pie in this tutorial? I make a backup of my system and wipe all data and clean operational system and reboot in recovery mode with only TWRP, then I install the Pie zip file and then, the files that you recommend in your tutorial. In the case I can have my phone root with Pie. I did that with my old V20 to Oreo, but I had to install the TWRP before reboot. In the case, can I do with V30?

Is there a way to relock the VS996 bootloader and get it back on a stock rom? There's no bootloader mode on the VS996 rom, so flashing the stock KDZ and locking isn't going to work. I though I could do it using the US998 rom, but the bootloader warning is still coming up on restart.
EDIT: I got this figured out... I think. I flashed a US996 rooted rom with TWRP, locked the bootloader from fastboot (fastboot oem lock). I was still getting the warning but the status was locked when I checked it from fastboot. I then flashed the current stock KDZ with the DualMode LGUP from the Frankenstein thread (using the REFURBISH option).

Yes, except it's US998 (V30), not US996 (V20) firmware.
You should never lock the bootloader while you still have TWRP custom recovery installed.
You were on the right track however.
You should have flashed us998 KDZ to get back to full stock. Relock the bootloader on us998 full stock.
No more warning.
Then use LGUP to flash to VS996 KDZ.

Ha, I definitely would have bricked it if I had got US996 firmware to flash.
Using the US998 KDZ makes sense. I think I had it in my head that it would take less effort to flash a zip via TWRP. It wasn't.

Because there's also VS996 TWRP flashable zip if you just want stock Verizon firmware, while keeping TWRP custom recovery and root.

Makes sense. While I run rooted stock firmware with mods on my own phone, I no longer help family/friends root their phones, run custom ROMs on their phones. Cuts way down on support phone calls to me.
