[Q] Roms on AT&T V30 (931) converted to US998 - LG V30 Questions & Answers

Hey folks,
I've got a relatively simple question about the V30. I've got an AT&T LG V30 which I used the frankenstein method to unlock the bootloader and convert to US998.
What I'm trying to understand is whether or not any of the LineageOS ROMs, or the 9.0 ROM, will work on the AT&T converted V30. My takeaway thus far is that they will NOT work on my device, and my attempts to flash the ROMs echo this, but I'm looking for a more definitive answer.
Am I dumb and just "doing it wrong", or is the 931 converted to 998 unable to run these ROMs?
Cheers!

No, they won't for now.
For those wanting more information about former H931 and H933 and AOSP ROMs, see here.

Please read around. There are multiple places saying it doesn't work. I am working on this. It is a slow process.
For a definitive. It does NOT work.

I've been looking, however I wasn't able to find if that was for all ROMs, some ROMs, maybe it works now and not at the time the reply was made, etc. It'd be cool if ROMs had a callout on the top post (as it gets updated when there are new releases) saying "INCOMPATIBLE WITH" or something along those lines. Just a thought.

Ohhh, see, I'm dumb and see the line in the FAQ that says:
Q. Which Models are supported?
A. So far it works well on the H930(G/DS), US998, VS996 and LS998 (use H930 zip). Other models may have broken RIL or bootloop. People with a H932, please use that zip.

And think "oh, I now have a US998 since I converted my 931, so this ROM should work for me."
Most of my lack of making since of this probably stems from the fact that I swear XDA used to have a set of forums for each carriers version of the device, but in the case of the V30, all carrier releases are clumped together under one section.
Thanks for your help! I'll look specifically for 931 in the device list and remember that even though I converted to a US998 via frankenstein, it's not actually a 998.
Cheers!

Yes, previously that was the norm -- even completely separate forums for each carrier, but then most users just focused on THEIR variant/their carrier and missed compatible developments that other variants of the same phone had. "Unified" development is better. TWRP/ROMS for all where possible.*
In this case, if you had a separate H931 or H933 forum, right now there would be no custom ROMs available. All you would have is stock-based ROMs like Boombox. It's also entirely possible we wouldn't have even figured out (together) that someone could flash to US998 in the first place to get bootloader unlock and root. It still might be only original US998 and H930 which have bootloader unlock and root with bootloader unlock codes doled out by LG.
But due to the one forum, and shared development that's how [b @TxanMoe accidentally discovered WTF bootloader unlock while using Frankenstein.[/B] @runningnak3d helped him recover his phone when he ill-advisedly tried to flash his H931 to European H930 after first converting to US998 and running some old Huawei bootloader unlock code he found in an LG G4 forum Yeah, he bricked his phone and we all smirked because he was doing stuff that seemed crazy. But after his phone was recovered, his bootloader was indeed unlocked. That became the foundation of WTF bootloader unlock and root. Without a unified forum, I'm not sure enough people would have paid attention. @TxanMoe would have just bricked his phone and that would have been the end of it; he would have moved onto another phone and we would not have realized the wonderful discovery of the LG bootloader unlock exploit.
There are devs working on the problem of H931 and H933 on AOSP ROMs.

* In the Moto Quark forums (Droid Turbo/Moto Maxx/Moto Turbo -- all the same model phone, just different names for some strange reason) the CM dev at the time make sure his stock CM Quark kernel (the foundation of all custom ROMs) was compatible with Droid Turbo when it finally got bootloader unlock a YEAR after all the others. Thus all those variants could run the SAME CM/Lineage-based ROMs and have the same TWRP. The dev that succeeded him @BHB27 kept up that tradition.
It started out as one forum, but then the Droid Turbo owners complained because their bootloader was not unlocked and they were tired of seeing all the "development" the other phone were getting. So, the forums were split almost a year after release, and ONE MONTH LATER the Droid Turbo bootloader was unlocked and suddenly they WANTED all that development back! That's where I saw it was a mistake to split forums. It's better to keep them all together so they can share development.
In the same vein, the V30S should NOT have a separate forum. That was an XDA mistake. It's a V30 Joan, just like all other V30 and all V30S should be here. This is where the V30S ROMs are, this is where the V30S TWRP (Joan) is, this is where the WTF bootloader unlock and root is. They should merge the V30S forum with this one and use that space for something else...
