Hi,
I think I screwed up. I followed this guide for my AT&T LG V30 and finished successfully:
https://forum.xda-developers.com/showpost.php?p=76584629&postcount=193
Then I went into TWRP and flashed this rom:
https://forum.xda-developers.com/lg-v30/development/rom-lineageos-15-1-t3789793
It seemed to flash fine, but now I'm stuck at the LineageOS boot logo.
Can anyone please help me out? I'm trying to flash LineageOS on my phone.

AT&T means H931, which probably same as H933 needs some special work to be able to boot aosp based roms. The H933 people figured it out, but are still writing a easy as possible guide.
Will (hopefully) also work for the H931 then. Be patient.

OK, thanks for the reply!
Hi, I'm using a converted us998 with stock 20h, bl unlocked, rooted and twrp 3.2.7 installed. I wanna install aosp-based pie ROMs, but after trying many them, like los 16, havoc 2.9, crdroid 5.4, all of them stuck at their specific boot animations. I'm sure the process of flashing these ROMs are all correct that data, cache, dalvik cache and even system are all wiped before flashing the new ROMs. I also tried los 17 with or without permissive patcher, but it behaves the same.
Before requesting help here, I tried to flash in twrp 20e to see if anything would change, but not at all. So I wonder if I need any kdz work, as currently I have some difficulty to get access to computers.
By the way, this phone I got from a former user, and he told he had used havoc and maybe tried stock pie, but I'm not sure what he had done with this phone. Since I got the phone, I had done no system-level change but daily use. The stock 20h running now has one issue since I got it: after any accident reboot, it may reboot itself every 1-2 minutes, and triggers of wifi, bluetooth cannot work during the process. Only forced reboot while its automatic rebooting can break the misbehavior.
If kdz work is indeed needed, could I convert it to h930 from nougat? I see h930 gets more frequent update.
I was facing similar problem.
But I am able to boot LOS17.1 now. I use this method #3 mentioned in Stock US998 Pie thread on post #4.
basically you need to Partition DL to H933 10h first, just give it a read. This is the only working method for me.
you did flashed Stock Pie firmware, didn't you? It's mentioned here that flashing Stock Pie will gives you irreversible changes to your device that cause problem when you flashed Stock Oreo and AOSP 9.0, they say it'll mess up sensors and camera, but for me I can even boot AOSP 9.0, and haven't go back to Stock Oreo ever since, so idk.
it looks like your only option is AOSP 10.

IF you have a former H931 or H933 converted to US998 you need to follow the AOSP prep stages here for any AOSP ROM to boot:
* Running any AOSP ROM on an US998 converted H931
* [GUIDE] Canadian H933 compatibility with AOSP ROMs
This is mentioned in the WTF Instructions with link to
ADVICE ON CUSTOM ROMS
See post #2, point #2 of that "ROOT YOUR V30!" Sticky Guide.
You don't say WHAT your former variant is, but I assume it's one of those if you are having this much trouble...

To run LOS-17 ROMs you additionally need to first flash LG stock Pie as a base. The LOS-17 (Android 10) ROMs need the LG stock Pie blobs (drivers). Whereas, LOS-16 ROMS use the LG stock Oreo blobs.

YES, all this information should be posted in EVERY ROM thread, but it's not. However, I wrote "ROOT YOUR V30!" Sticky Guide so people would still have that information. Same reason @tech_infinity maintains an ASOP bugs thread, which is something else that should be posted in every ROM thread!
* BUGS ON LOS-17 (Android 10) ROMS
* BUGS ON LOS-16 ROMS (those 7 will probably never be fixed)
Uh, sadly I made a mistake and almost bricked my phone. See Help! bootloop per 5 sec, cannot enter rec, download or fastboot

I'm back from the 9008 recovery. I think the original variant of my phone is ls998 as the former owner told me. I have been tired doing anything with North America variants, so if it's feasible to move to stock h930 base as I don't care about baseband, @ChazzMatt?

1) It's strange if you have former LS998 that you can't boot any AOSP custom ROMs. No one else has that issue. Whereas H931/H933 are documented with needing additional prep. Is your phone V30+ (128GB) or just V30 (64GB)? That would definitely tell you what the original variant is. H931/H933 are only 64GB, whereas all the LS998 I've seen are V30+ (128GB).
2) I'm never going to advise anyone to flash anh H930 variant KDZ over North American phones. However, some people have done it, as long as they EXCLUDE certain partitions when flashing H930 KDZ with Dev Patched LGUP in Partition DL mode.

That guide above was made when people were too impatient to wait for US998 to get Pie, so they partially converted to EU H930, just to get LG stock Pie. It's not like Frankenstein where you fully convert all partitions, and even change LTE bands.
Also some people have done it to get East European languages not present in the North American firmware.
From what I understand once you flash the H930 stock firmware, it's hard to flash back -- but that may have been the stock "Pie" effect, with sensors messed up, etc -- as people were flashing back to US998 stock Oreo once they tried EU H930 stock Pie. We've managed to overcome that "Pie" effect for the most part, by flashing Nougat then going to Oreo.
(For others reading this do NOT try it with T-mobile H932!)
My apologies in advance if this has been discussed before. My searching has only lead me to threads stating not to flash to pie without upgrading. I had some trouble connecting to the phone but after finally working through it and getting the bootloader unlocked and TWRP on the phone, it was late and I flashed LOS 16 before properly upgrading through each iteration of Oreo(20a -> LOS 16). The phone seems to be working fine. My question is, do I need to flash back to Nougat then oreo as discussed in some of the stock pie threads or can I just flash back to oreo 20e up to 20h?
Thanks.
Phone is US998 flashed to LOS 16 from Oreo 20a

Yes, you can flash US998 20e, f, g, h, then flash back to LOS 16.
LOS-16 doesn't have to persistent changes LOS-17/Android 10 has. So, no need to go back to Nougat to scrub it clean.
hello so i got a refurbished us998 on android 7.1 i couldnt get it to update vie ota so i flashed oreo firmware with lgup after that i unlocked bootloader and installed twrp all good but after that i wanted to update to pie so i can install android 10 custom roms i flashed the pie kdz and i got stuck at lg logo couldn't boot then i tried with flashable zip same i tried flashing back 7.1 then to pie that didnt work then i flashed all the oreo zip from build 820e to 820h as mentioned in a thread and then pie

In the US998 Pie KDZ thread, there's several methods to get to Pie. Look at post #2 and post #6. It sounds like you tried some of those, but read again carefully. Method #4 in post #6 seems to work for almost everyone.
You can't flash LOS-16 immediately after failing to update to Pie. Enough Pie infected the partitions that it will not work. So, if you want LOS-16 you have to flash back to Oreo first. LOS-16 needs Oreo blobs (drivers).

Hi!
I gave my old V30 away that ran custom ROMs quite a while and flashed it back to stock for that, since the new owner is not a techie. I used a TWRP-flashable stock ROM for this.
But now neither camera nor torchlight do work.
Did I forget something?
You'll need to tell us what ROM you came from. Pie ROMs, for example, can't be TWRP-flashed back to Oreo. Other custom ROMs have even bigger issues.
I would recommend KDZing back to stock. If you're going back to Oreo, you may need to go back to Nougat and then up through the others into Pie, because some of the Oreo KDZ made incremental changes that are needed for Pie. At least that's my understanding on the matter...
Safest would be to back to KDZ Nougat, then go through the rest until you're at the version you want... but there may be some shortcuts.

WHAT stock did you go back to? Oreo or Pie? If you were on LG Pie (and custom ROMS needing LG Pie), going back to stock LG Oreo breaks flashlight and camera. Warnings are listed in the Pie KDZ Guides about this. You have to flash back to Nougat to scrub out the remnants of LG Pie and then you can go to Oreo.
Sometimes even then you have to still run in "permissive" mode to let camera and flashlight work right.
