By ROMs, what do you mean? Custom ROMs you flash after bootloader unlock like

WETA ROM

-- or stock firmware KDZ? Yes, all US998 custom ROMs are compatible as you will now have a US998 phone.

If you mean are all stock KDZ compatible, you can convert any North America LG V30/V30+ phone to any other North America LG V30/V30+ phone (except T-mobile H932) by using dev patched LGUP and having appropriate KDZ. For instance, AS998 owner just flashed to Canadian H933 V30 today, because he believes the H933 modem is stronger. He doesn't care about bootloader unlock and root. Sprint LS998 users who don't use Sprint would be loathe to go back to Sprint firmware as that's locked down severely. They welcomed the escape to a carrier unlocked variant. If you're not a Verizon user, why would you convert your phone to a VS996?

But YES, except for T-mobile H932, all the North America KDZ are compatible where they exist. AT&T won't release KDZ. They only release firmware via OTA updates to actual AT&T customers.

In North America, the US998 is the only V30/V30+ with fastboot flash commands and the Oreo bootloader unlock exploit. It's also the official carrier unlocked model (besides being the U.S. Cellular model) and has bands to support all carriers. (Except it's missing a couple of pesky Sprint LTE bands, apparently. But you can add those back by re-flashing Sprint modem.)

Tell me what you mean by going back to stock VS996? I'm trying to understand what you want. You can flash Verizon modem and stuff and probably even most firmware, while still keeping unlocked bootloader and root. Already someone has share their modem, and you can get Verizon Wi-Fi calling:

But yes, you should be able to completely flash Verizon Oreo KDZ and wipe out your unlocked bootloader and root, if that's what you want. Same way people were able to flash the Verizon Oreo KDZ over the US998 in the first place before US998 got Oreo. They "converted" their US998 to VS996.

I'm just not sure why you would want to do that, give up unlocked bootloader and root. The best solution is the step in between like where Sprint guy [MENTION=2732656]JWnSC[/MENTION] flashed Sprint modem and some system stuff while still keeping his unlocked bootloader and root.

I'm hoping somebody can help me out here. I finally had some time to frankenstein my vs996 to us998 on oreo. I have adb and fastboot set up and have no problem getting the device to show in CMD or "adb reboot bootloader" but when I try the "flashboot flash unlock unlock.bin" command (I renamed the new_unlock.bin file) it just hangs at sending unlock. It wont do anything at all until I manually reboot my device. Please, for the love of God, someone have some advice or direction for me. I feel like I tripped 5 feet short of the finish line at the Boston Marathon lol

You can try it. It work for me

You should create LGUP folder at "C:\Program Files (x86)\LG Electronics"

Then you dowload "LGUP+V30DLL_PATCHED.zip" file at https://xdaforums.com/lg-...-h930-t3779076 and unrar. Copy all file after unrar to C:\Program Files (x86)\LG Electronics\LGUP

[LG V30 Guides, News, & Discussion] JWnSC:
Is your device recognized in fastboot? What happens when you type "fastboot devices"?
[LG V30 Guides, News, & Discussion] ChazzMatt:
But with AS998 it worked OK? What band or bands specifically?

Have you tried adding a new APN?

If you flash back to AS998, does it work again? If so, look at the APN and see if there are any difference between the two when flashed to H933.

How about to US998?

There shouldn't be much difference in bands between the three.

What's confusing me is you are receiving a signal (voice) just not data. Often that's an APN or SIM card issue.

On one AT&T MVNO years ago I had to manually edit the APN to enable data. It didn't auto configure correctly.
[LG V30 Guides, News, & Discussion] lafont28:
I just tried it again. This is the response I get and then I am instantly kicked out of fastboot mode. Should I go back to Nougat and maybe start the process all over?
[LG V30 Guides, News, & Discussion] Arcide:
If you used the unlock.bin instead of new_unlock.bin, then it should say it failed, but it actually succeeds. Check if it's unlocked before trying something else.

i try to add APN but it doesnt work at H933

You can also try flashing US998 to see the difference.

Also from US998 you can bootloader unlock and root. With root you have more control over your device. ;)

Then after that for experiment, you can reflash H933 modem (only the modems). With root, you can add all the APN you want.
[LG V30 Guides, News, & Discussion] lafont28:
Yes sir. Ticked oem unlock and switched to photo in usb, then adb reboot bootloader. Fastboot devices works and so does fastboot oem device-id but flash unlock gives me the finger, basically, everytime. This is really making me miss my Nexus 6.

I see that you were in the same situation as me, only youve been successful in frankensteining your phone. Ive booted into download mode, installed LGUP patched, and this is the message i get on the screen when i try to go from VS996 to US998...."DLL for VS99620b is invalid. Please, install valid DLL package (*msi). for the model"

Im not getting past this. do I not have the correct patched LGUP?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Then something has to be wrong with the new_unlock.bin file you downloaded. You can either download from [MENTION=6158380]TxanMoe[/MENTION] link or from the post attachment. Try whichever one you didn't do before.

I'm converting my 2nd Sprint V30+ which has Sprint Nougat to US998 Nougat right now. Next, I'll upgrade to Oreo US998 when it finishes. I'll keep you updated.

I had to UNcheck the .bin section (it had already chosen the Oreo Nougat from previous phone flash) to make the 3 dot selection on the right side show up again, for me to select the Nougat US998 KDZ.

OK, I'm now at the Master Reset stage.

Successfully converted Nougat Sprint to Nougat US998, now back in Download mode to go for Oreo US998. For some reason LGUP still recognizes it as Sprint Nougat, even though I've confirmed in About Phone it's now US998 Nougat. Wheras Download Mode recognizes it as US998 Nougat.

Flashing Oreo US998.

Hey, glad it all worked out for you.

Can you inform us what the solution to the problem was? Someone else now says they can't flash the unlock.bin file and that was what you had trouble with also. If there is something I can add to the instructions I'm glad to do so...

Follow these instructions below for bootloader unlock. Since you are already on US998 firmware (converted from LS998), you are over halfway there. You just need to flash bootloader unlock code, install TWRP and root. Skip down to the "Let's Go" stage of those instructions. You've already done the hard part if you are on Oreo US998.

H930DS Frankenstein Flashing

Bootloader on the 930DS has been unlocked using the fake boot.bin method and the device has been rooted and TWRP installed. Here is what we've found cross-flashing different V30 variants software on the H930DS hardware:

1: H933 (aka Canadian model) firmware installs and boots without issue, only problems are the lack of ADB and Fastboot capabilities in kernel and a disabled modem.

2: US988 firmware installs and bootloops continually once the phone setup begins. Never had the chance to configure phone and attempt to root

3: LS988 (aka Sprint CDMA model) firmware installs and boots without issue, only problems are the lack of ADB and Fastboot capabilities in kernel and a disabled modem.

We are trying to get access to the AWS frequencies available to North American devices and on rooted H930DS downloaded “Shortcut Master (Lite) and tried to enable AWS frequencies, phone phone shows all LTE bands available except Band 46 ( Available bands include 66 and 71) and all WCDMA/GSM available except WCDMA 900.

Yes, it will be carrier unlocked and have the GSM/CDMA/HSPA/LTE bands of the carrier unlocked US998. If you want to use it on GSM carrier you can.
