So, got my V30 here, Frankensteined H931 to US998, never had basically any issues with it so far. Decided to attempt to install the TWRP flashable US998 30b from John Fawkes and that's when all hell broke loose. But I won't get into all that, here's the primary issue now:
I get Download Mode when I power the V30 off and hold Volume Up + insert USB cable (and I've done this with multiple USB cables as well as multiple USB ports), but I never get a connection to the computer anymore in that mode. Nothing, no connects at all, no sounds to indicate a connection, while the V30 shows it's in Download Mode and is waiting for a connection.
If I power it off back to TWRP (3.2.3.7, just flashed earlier as instructed because of the Pie attempt), I get all the proper connections, sounds, etc, can copy files over to the internal as well as external storage, no issues.
Normally when most people say they can't get into Download Mode it's some issue where the device won't power on into that mode when the USB cable is attached - that's not the case here as stated: it powers on and says Download Mode and waiting for a connection, but regardless of any USB cable or port there's never a connection.
I'm suspecting it's a software issue since obviously on a reboot into TWRP the USB port works exactly as expected.
Any suggestions? Because of this I'm unable to do a clean proper US998 20h KDZ flash or the 30b KDZ flash either so thankfully I did have a backup of my previous 20h Oreo install. Of course, because it's all pooched now that is effectively useless because of course of the encryption and upon restoring the backup it won't boot because of the password crap and forces me to format DATA and start all over again.
/me hates encryption when this BS happens, seriously...
So, any tips or tricks that might get me back to a working connection with Download Mode? Flashing a particular partition or something? I'm basically about to redo it with a clean 20h TWRP flashable here in a bit, not left with many other options now.
Anything is appreciated, thanks...
1) Try flashing US998 20e TWRP-FLASHABLE zip. See if that gets you download mode back.
If not, then
2) Try different LGUP.
______
After you get Download mode back, try these steps. Helpful people been testing this out...
For users with TWRP who get stuck on LG logo.
* Flash Verizon VS996 Nougat Partition DL -- EXCEPT for Recovery partitions, to keep TWRP. Do NOT choose all partitions!
You will probably lose download mode, but you've prepped your phone, corrected any partitions. (This is not just for Verizon users, this is for all North American variants -- except for T-Mobile H932.)
* Flash US99820e TWRP flashable zip to get back Download mode.
* Then REFURBISH to US998 20h KDZ.
* Now flash TWRP recovery again and then flash John's zip US99830b.

See Instructions above. Going to write something up in the US998 thread.
Yah, the 20e thing got download mode working normally meaning when the device went into that mode I'd get the traditional notification from Windows that a USB device was now attached - that's what was missing previously for whatever reason.
So I flashed 20h clean with the dev patched LGUP, no issues with Partition DL because I wanted it truly clean without anything that shouldn't be there, and that meant the factory recovery partition as well.
Then I attempted to flash the 30b KDZ, no joy, just stuck at the LG logo and I've wasted enough time on this now so, I'll just wait till some other point and maybe give it a shot in the near future.
Kinda sucks starting over totally clean but hey, this phone has worked near-perfectly since I got it in May so it'll be fine with a clean fresh start. I'm not even going to install Magisk this time, I can't think of a single reason I even need root anymore but if I do I'll worry about that a later time.

You need to do the VS996 Nougat Partition DL step. It preps the phone.
This is what you need to do:
I have all the steps above. The first 20e flash was just to get Download mode back.

Let me start firstly by saying, thank you ChazzMatt! V30 owners around the globe are incredibly fortunate to have your dedicated write-ups and support for these terrific phones. FWIW, I'm seriously impressed with the level of knowledge and your willingness to deep dive issues with folks... thanks again!
Getting to the topic however; I have the identical issue occurring with my LS998U (V30+) that I just went through the unlock process with yesterday. This morning I TWRP flashed the VS99630c ROM and everything worked A-OK except download mode. Exact same symptoms as br0adband is describing - phone appears to enter download mode as normal (though the initial "LG V30 ThinQ" boot screen appears to have replaced the bootloader warning screen?) but is not initiating the USB port for a connection at all.
Connections are established and work normally in TWRP and when booted into the OS so there appears to be something fundamentally wrong with Pie or the flash method.
I'm 99% confident it's not a PC side issue as there isn't even a connection for LGUP or drivers to fault out on.. I also tried my other US998 phone which is on dotOS and everything worked normally.
I'm about to try the TWRP flashable 20e per ChazzMatt's suggestion and will report back if I have success (or not).

VS996 firmware doesn't have bootloader unlocked warning. Verizon never thought it would ever be unlocked.
While flashing 20e should give you download mode back, to me or seems both of you are sort of missing the point of the preliminary VS996 Nougat Partition DL flash (while omitting the Recovery partitions to keep TWRP)
Maybe in your case you don't need it -- since you made it to the other side of Pie, but that Nougat flash fixes any Partition problems. Just be sure to keep TWRP during that.
You may temporarily lose download mode again
Then TWRP-flashable zip US998 20e fix that.
Then REFURBISH to US998 20h. You'll temporarily lose TWRP at that point.
Re-Install TWRP and the three root files.
Then flash US998 30b TWRP-flashable zip.

While my "missing the point" is entirely possible ChazzMatt, I was under the impression that I was already AT the preliminary Nougat step after having just stepped through the Frankenstein and unlock methods?
My progression through those steps was simply;
Frankenstein per your post here; https://forum.xda-developers.com/lg...ssflashing-t3780969/post76510671#post76510671
Unlock the bootloader, install TWRP et. al. per your directions here ;https://forum.xda-developers.com/showpost.php?p=76584629&postcount=193
Upon completing these steps, Nougat is already installed at which point I figured I was ready to flash VS99630c. What am I missing here... should I have reflashed Nougat?
I didn't have any issues like others are reporting with the upgrade to 30c (TWRP flashed it flawlessly and it booted right up).
It wasn't until I decided I'm not ready for Verizon Pie (tastes gross) and went to step back to US99820h that I realised Download Mode was broken.
Is all of this not just a case of Download Mode being broken in 30c for everyone?

Does Download Mode work for anyone after this step or is TWRP back to a 20 series ROM the only way back to a working LGUP?
Sorry if I'm only confusing things more but I figure I'm not the only one tripping up on this... once I understand it better, I promise I'll step in and help educate other folk
It really is true about ChazzMatt's willingness to help around here.
What I never could understand is why some users, after receiving help AND successfully using it to fix their phones, don't even bother saying thank you. I'll happily spend my daily Thanks quota on helpful posts, even if they have no relevance for me at all. And I see Chazz do the same, every day. Others too, of course. But it seems some people feel being thankful is beneath them. Or something... I just don't understand it.

No, download mode isn't broken for everyone. Most people flash to Pie with no issues and download mode still works. It's when reverting to US998 Download mode seems to go away for a number of poeple (not sure how many and may depend on the LGUP used)
_______
OK, if all you wanted was for Download mode to be restored and you had no problems getting to Pie before that, then ignore what I said.
I thought you were trying to get to Pie and couldn't. In that case the workaround involves flashing Verizon VS996 Nougat -- NOT US998 Nougat like in Frankenstein -- via Partition DL mode except for Recovery partitions. That's a necessary prep stage for Pie. Both people in this thread weren't doing that. OK, so you had good reason. :silly:
THEN going to US998 20e via TWRP flashable zip, which restores Download mode. But if the goal was to get to Pie (yours wasn't) flashing 20e to get Download mode was also step zero. It was also necessary to restore Download mode so you could then flash VS996 Nougat via Partition DL mode (except for Recovery), to then flash back US998 20e TWRP flashable zip AGAIN, to then REFURBISH to US998 20h.
The VS996 Nougat part is important for those people hitting the LG logo wall.

This is good news... thanks for confirming!
I've likely done a few hundred ROM flashes and plenty of roots/unlocks in the past 15-20yrs and this was the first time I had a genuine "Oh crap" moment where a low level mode like Download Mode truly failed.
I was also having trouble getting back into TWRP (Noxx PM refused to work on 30c) which fostered a rapidly growing concern that without TWRP and Download Mode, I was effectively bricked (or at least in for a few hours of work to find a resolution).
I breathed a sigh of relief when attempting a Master Reset led me back to TWRP... I still had options!
Anyhow, it's probably fitting for me to exit this thread on the same subject I entered on by saying thank you again for the information share and willingness to help out :good:
Cheers!

KDZ 99820a
Hello i wanna thank all of you guys for the amazing support on this device, he LG v30 is an amazing phone just bought a US99830B , downgraded it with LGUP to oreo, unlocked bootloader in oreo and installed TWRP downloaded 99830B flasheable zip and flashed it , then i waned to try lineage 17 and flashed it in TWRP clean install booted up in android 10 but noticed lots of bugs and no WIFI, flashed modem for oreo in TWRP wifi came back up but wanted to go back to PIE restored from a backup that performed for PIE and got botloop maybe because of the incompatible modem, tried download mode, no USB activity back to TWRP restored lineage OS and im back in the system, i took your advice to flash 99820b in TWRP my download mode is back and im on oreo, my question is if i KDZ 99830B from 99820b will download mode still work even tho it doesn't when i flash stock 99830b download mode gets lost, i dont want to flash the KDZ and end up with no download mode and no TWRP and have a hard brick
Update : I have KDZ 99820a using LGUP and locked bootloader I'm back to stock is there any issues if I update to the 99830b which is the original software that the phone came with? Can I perform that update via KDZ?

Losing your download mode has nothing to do with stock.
Why did you lock your bootloader back? You can run stock rooted firmware just fine and have lots of advantages like DTS surround sound stereo.
I don't understand why people lock the bootloader back just because they decide they don't want custom ROMs. The best thing to do is run rooted stock firmware, have everything you want.

Don't get me wrong i like having rooted devices because of the endless possibilities it offers but this time mayor newer games that are coming out they have the ability to detect if you are rooted or if your bootloader has been unlocked and they kick you out of their servers, that's the main reason why i want to go full stock, and I was so afraid to do so because some people are reporting when moving from oreo to pie it creates bootloop and since I had issues when I was rooted and flashed via twrp 99830.zip download mode won't detect the USB cable only when I rolled back with LGUP to oreo downloadode started working and I KDZ oreo to have official recovery and relocked bootloader but I want pie is just I am not sure if I can go up with LGUP to pie using 99830b (which my phone originally came with pie) from 99820b
Could you please help me with the same problem with download mode on h932? I'm on stock pie now. I want to downgrade to nought but my PC not recognize phone in download mode. Thank you.

First try a different USB port, different cable and/or different computer. If you never rooted the phone, there is very little chance that your actual Download Mode got corrupted, and one of the above will most likely solve it (although many doubt it because it sounds too trivial).
Also, make sure you're using the latest Dual Mode Dev patched LGUP from one of ChazzMatt's ROM threads.
Next I would try the Update Recovery mode in LG Bridge (on the Update tab).
Finally, if none of those work, you can try force installing the Pie OTA using LGUP FOTA mode (doesn't require Download Mode). It's described in the thread linked below. Best to read the whole thread for context, it's just a few pages.

I tried all things with cabels, PCs and drivers, i'm not sure but as i know LG phone in download mode should be recognized as anything, but in my case i have no any devices in the device manager. I didn't root this phone but i bought it with unlocked bootloader so it is possible that it was rooted. I tried lock bootloader but it didn't helps so i unlocked it again. Now i'm going to try to flash OTA file. Thank you so much for help.

Does Download Mode start on the phone?
Just to make sure: From Power off, press and hold VolUp while plugging in the cable. Then load LGUP. Again make sure you're using the Pie compatible LGUP from one of ChazzMatt's ROM threads.
Otherwise I'd try LG Bridge next.
As for force installing the Pie update with LGUP FOTA (the thread I linked) we've only had one confirmed case of it fixing Download Mode so far, although not many tried it yet. On Oreo we had many users confirming it, but Pie is different.
I should add that if you have working Pie, but just would like to roll back, there is a risk that the FOTA will mess up what you have. So if it doesn't fix your Download Mode, you could be worse of. Just a heads-up

Actually the main problem is that phone doesn't recognize by PC when download mode is on the screen. I have tried to use lg bridge to recover, but anyway it reboots my phone and then my phone doesn't recognize. Now i'm trying to solve lg up error with FOTA update, it looks like wrong dll file.

Just bought a VS996 on Ebay and followed the Frankenstein steps to get it to US998 and then WTF unlocked the bootloader, installed TWRP, removed encryption, etc, and finally the Verizon 20i ROM designed for TWRP/root.
All was well for a brief time. Then I started debloating the ROM and installed a Magisk module -- Terminal Debloater or something -- figured it was harmless.
Rebooted and I no longer have the Bootloader warning screen and the Verizon white screen with animating dots comes up but never moves past that. I waited at least 15 minutes and then hard reset.
Fortunately I could get into TWRP still so I wiped and flashed the ROM 20i ROM and Magisk again which will boot just fine.
Unfortunately, Download Mode (which worked previously via the Volume Up key for the Frankenstein method) no longer works. I see the mini Download mode icon and then the phone reboots to the LG V30 screen and then the OS. Tried going to Download Mode via ADB and it won't stay then either. Somehow my LAF partition got corrupted?
So TWRP works and so does the 20i ROM rooted. Just no Download Mode. Also "adb reboot bootloader" doesn't work either - just goes to the OS.
Is there anything I can do to bring back Download Mode?
Thanks,
Drew
Once you're on vs996, you don't get the bootloader warning anymore.
Extract the TWRP flashable package, get the laf image and write it to your laf partition with dd. You can also flash it from fastboot

So in vs99620i.zip found: https://androidfilehost.com/?w=files&flid=287569, I see in the bootloader folder there is a laf.img. I've recently installed the whole ZIP again so shouldn't that have fixed the Download Mode? Or could it be that this ZIP is the reason for the messed up Download Mode in the first place?
Anyway, assuming there's nothing wrong with the laf.img, what are the steps for writing to the laf partition with dd?
I'd ask about the fastboot steps, but I'm not sure I can get to it... As mentioned in my OP, "adb reboot bootloader" is accepted via ADB, but the phone reboots and just goes past the bootloader to the OS. Not sure what is wrong with my bootloader either... Or is it because I'm on VS996 and no longer US998 that I don't have fastboot?
Thank you!
You are correct. Since you flashed back to VS996, you no longer have fastboot.
As for laf, you can use any laf image. Go to the H932 root thread and there is a TWRP flashable laf zip in the first post.
If you want fastboot back, you will need to flash xbl and abl from the US998. Let me know, and I will make you a zip for that as well.

So helpful, thank you Brian! Yes I would be most grateful if you could make a fastboot zip for me/others!
There is no issue flashing an H932 laf image/zip on a VS996? I know H932 isn't like other N. American V30s in terms of the WTF method, so just want to be sure I don't mess things up. Maybe you/I could make a US998 laf image/zip?
Thank you again!
Nope, there is no issue flashing any models laf. The laf in that H932 thread isn't even an H932 laf, it is an H930 or H933 don't remember.
Laf is laf is laf
I will make you a zip for fastboot as soon as I can.

Flashed the h932_laf.zip in TWRP and think it was successful. However, I still cannot get into Download Mode -- it just reboots and goes to the OS. Guess no more LG UP fail-safe for me? Or is there anything else I can try?
Thanks!

What steps are you taking to go into Download mode? I'm not doubting it's possibly corrupted, just want to make sure you have tried both methods of getting into download mode. LGUP and manually?
Apologies if you have tried this...
Manually with the hardware buttons:
Press and hold the Volume Up key on your LG V30.
While still holding this button connect your phone to the USB cord on your computer.
The download mode should now be displayed on your device.
You can release the Volume Up key and resume the update / downgrade operation.

Actually, without fastboot, the vol up + USB is the only way to get to download mode.
Just an FYI, the phone has to be powered off.
So, power off the phone, hold vol up, plug in the USB cable.
There is no reason you wouldn't have download mode if you have a valid laf partition.

No worries, but yes I have tried that. I get the Download Mode tiny icon in the center of the screen and I keep holding Vol Up and it then reboots back to the same tiny icon over and over. I eventually release the Vol Up and it just goes to the OS. But it worked perfectly when I got the phone Friday and tried the Frankenstein LG UP method, etc.
I have also tried rebooting into Download Mode in ADB via "adb reboot bootloader" and also using a root-only Power Menu app in the OS but both just reboot and go right to the OS.
My hunch is it somehow got corrupted when I:
1) Used Titanium Backup to uninstall some system apps like Music, Youtube, Photos, etc and the white Verizon loading screen never let me into the OS and I had to hard reset.
2) Installed vs99620j.zip by John Fawkes which won't boot past the LG V30 screen. This non-booting issue may more have to do with the 20J KDZ than what John did, and no one else has complained about a loss of Download Mode in that thread when I asked the question there.
3) Installed a Terminal Debloater module in Magisk previously. Never actually ran it though, but I installed it as I was debloating via Titanium Backup and when I rebooted, the OS would never load.
I have subsequently flashed the 20i VZ zip with a laf.img and the H932 laf img ZIP which should each have fixed the Download Mode but neither has.
Could there be something else other than the LAF partition which causes my phone to not enter Download Mode?
EDIT: Noticed that my computer's LGUP sees my phone just fine when the Verizon 20i ROM is loaded -- shows up as on COM14 in STANDBY. Download Mode, again, is another story! (And no I don't have LGUP loaded before doing the Vol Up method normally. Tried it this time though just out of curiosity and nothing showed up in LGUP.)

Sounds a little bit like you were trying to do too much at one time. I understand the impatience.
Also, others have reported the vs99620j.zip may not quite work right. The dev is investigating issues.
Last, be very careful about debloating where you are permanently removing stuff. With this phone a lot of stuff is connected in ways LG knows and we don't. Personally, I prefer FREEZING in Titanium Backup rather than uninstalling. (However I know Verizon does shove a lot of bloatware down your throat, while I have a US998.)
First, there's system space and user space. Uninstalling "system" apps do not gain you any user space. It may make people "feel better", but it has no advantage whatsoever over just freezing. With freezing, out of sight out of mind, and you won't cause lag because the roots are ripped out and the phone has to pause while searching for something it can't find. (I'm not talking about Verizon branded bloatware, but other stuff.)
Second, if you find you DO need something you froze, it's then simple to unfreeze. There were people who messed up their AOD, their GPS, their Google Pay, their microSD card storage by debloating willy nilly from some alleged "comprehensive" someone posted in this forum of ALL the stuff that could be debloated. Just because you can remove it doesn't mean you should. There was a lot items on that list you should never even touch, unless you are trying to turn your modern smartphone into a simple flip phone.

Yeah, you're right about Freezing as that's what I did after having the Uninstall issues. And yes, you are right about it not recouping user space either, so I am fine just Freezing.
Regardless, not sure why Uninstalling system apps would mess up Download mode; if anything I could see the ROM not loading but that's about it.
Any thoughts on restoring Download Mode in some other way? It's not critical for my phone to work right now, but I can imagine a situation where somehow TWRP gets overwritten somehow and the stock recovery is practically useless. Thankfully I have TWRP and a rooted VZ ROM for now, but it'd be nice to have the insurance in case bad anything happens!
Thanks,
Drew

You won't be able to ADB reboot bootloader while on Verizon firmware. However, if you flashed US998 TWRP flashable zip (converting back to US998), you would again have fastboot flash commands, etc. That might be worth trying, then later you could always flash back to Verizon TWRP-flashable zip.

It does seem somehow your Download mode has been corrupted. The only things I know of (and I'm not a dev) about how Download mode disappears is either corruption or you flash something else over it. Some T-mobile H932 users flash an extra copy of TWRP over LAFF and they lose Download mode -- but they are doing that on purpose for reasons specific to the H932.

Nope, there is no issue flashing any models laf. The laf in that H932 thread isn't even an H932 laf, it is an H930 or H933 don't remember.

Any other ideas for restoring Download Mode or is that pretty much shot, you think?
So thanks to the H932 guide and the following, I now have a 2nd working TWRP in place of my Download Mode/LAF partition. When I hold the Vol Up and plug in a USB cable, I first see the tiny Download Mode image as before, but then the 2nd TWRP loads up! Not sure why when I restored a working laf img via TWRP before, Download Mode still wouldn't work, but this will work via ADB. Guess TWRP as a fail-safe in many cases is better than Download Mode, so I'll take it! Perhaps if I flashed the laf img via ADB like this instead of TWRP, it would restore Download Mode, but I'll live with TWRP there for now.
Still would love to have fastboot on VS996 as Brian described on Page 1, if that's even possible.
If you would like a second copy of TWRP on your laf partition (I *highly* recommend this), follow these instructions:
Download the version of TWRP that you want to install onto laf.
Rename it to twrp.img
Boot your phone to TWRP, and connect it to your PC
Open a command prompt where you downloaded TWRP and type:
adb push twrp.img /sdcard/
adb shell dd if=/sdcard/twrp.img of=/dev/block/bootdevice/by-name/laf
With the phone off, hold vol up and plug in the USB cable and you should be greeted by your second copy of TWRP.

I have Verizon service so would I have any issues with US998 in terms of MMS or Voicemails or anything? I figured I'd be assured of no MMS issues (which I thought I read could occur with Verizon on US998) by going with a VS996 rooted ROM. Plus the VS996 ROM comes with the Verizon Voicemail app and maybe the US998 ROM's Voicemail app isn't compatible? The one thing I know I'd lose with US998 and Verizon is WiFi Calling... Believe that has to be done with the VS996 ROM, right?
I'm not sure I care that much about fastboot now that I have 2 TWRP partitions on my phone, so maybe I just stick with VS996 on Verizon.

It would just be temporary to see if you can get download mode back.
Then you can go back to Verizon TWRP-flashable zip.

I face similar issue when I reset my phone (also h932) and then TWRP deleted and replaced by stock recovery. I tried to install twrp again via lafsploit method no luck. my phone not detected on my PC. so I decide to download LG Bridge and perform an update (I assume that your phone can boot android). If your phone is already running 30d pie then click update error recovery (see image below). If you still on older version you can update to recent version without update error recovery

May I ask did your phone bootloader unlocked when update using LG bridge. Actually I try before using update error recovery but no luck. After download firmware when install update on stock recovery, it hang on 5% then restart. My phone is bootloader unlocked when I try. Is it necessary has to be on locked bootloader. Thank you.

yes, i did it with unlocked bootloader. in my case, i could enter download mode but my pc couldn't detect any device. have you tried to enter download mode manually? what's look like? mine says "unknown 0/0/0"
if you never try to flash laf partition with another things (e.g stock laf or twrp), it might be still using h933 laf, and that means you can try to flash twrp using fwul

Do you know what version of LAF you are running? It was pointed out in the root thread that after you get TWRP, you need to flash the correct version of LAF or put TWRP on LAF.

Reposting this here for visibility:
Hello all. So I am having a similar issue. I was already running a stock rom and I flashed the stock laf from the stock H932 thread. However, I noticed that the latest laf version from that thread doesn't match the latest firmware. I'm not sure if that was the cause but I lost my download mode abilities and twrp recovery (booting into recovery shows "no command". My bootloader is still unlocked and the device will boot into the stock system but download mode freezes whenever accessed meaning I can't use either oreo or pie LGUP to repair it. It shows Unknown B79 and says Unknown / E / L / RO at the bottom. Does anyone have an idea on if there is anything I can do to restore download mode? I noticed I have Would it cause problems to relock the bootloader at this point, as I would like to relock it with the coming changes to safetynet. Thank you for any help.
I don't have any suggestions other than what was already posted in the H932 root thread.
1) If you're NOT already on Pie, you should be offered an OTA update, which will repair Download mode (at least previous OTA updates did that).
2) If you're already on Pie, you need that Pie OTA file which everybody is looking for. Force flashing that with LGUP in FOTA mode (inside the OS) should also repair Download mode (at least previous OTA updates did that).
Do NOT relock the bootloader unless the phone is completely, 100% stock. Otherwise you'll get a brick on next boot, when signature checks are performed on all partitions. As I understand, this will blow a Qfuse, which is irreversible.

Thanks for the info. I'm already on pie. It seems the .up file is nowhere to be found. I can use the phone as is but with the bootloader unlocked I'm hoping that I won't be affected by the supposed upcoming safetynet changes. Is there no other way to repair the laf partition besides getting a hold of a file it seems no one has? Thanks for your help.

I do understand. But remember that Qualcomm, LG and T-Mobile all went out of their way to make sure that this phone was locked down and un-rootable. They stripped flash and boot commands from fastboot. And they choose RSA signatures different from all the other V30 models, so that it would be like a prison island in the middle of the ocean.
The only reason we can still root it at all, is because of a massive effort by a brilliant and knowledgeable Dev, who reverse engineered the boot and laf code. And he found this narrow path to let us root it.
But that doesn't mean the H932 just rolls over and starts to cooperate with us: It's still designed to make it as difficult as possible for us to do what we're trying to do. And it is very unforgiving of any mistakes.
So once both TWRP and Download mode and root (in the OS) are gone, there's not much left to fix the situation. The only thing left is LGUP FOTA. But it requires an OTA file. Several were posted for Oreo, but none so far for Pie.
Anybody with an H932 and enough time on their hands can capture it, if they're willing to roll back to Oreo (losing their data) then update again using OTA.

I understand, and I am also very grateful for the work put in by that dev and the many others here on xda who help other users out. Perhaps some generous person will be able to do like you mentioned and be able to capture the OTA link. Just out of curiousity, what would that process look like? Roll back to oreo via lgup? And then what would be the best way to capture the link? Could it be done without root? Thanks again for your input.

Yes, roll back to Oreo with LGUP. The best way to do that is via Nougat in Partition DL mode, in order to rewrite the partition table. Then to Oreo from there, Upgrade mode should work.
Then trigger the OTA (if it doesn't come right away) by changing the date forward a few days at a time.
Once the OTA is offered, there is a process to capture the link. I've never done it myself. The OP posted a link in post #1, but XDA scrambled it for the benefit of... well, someone, we'd hope. Google should be able to find it.
One thing I forgot: You can also try LG Bridge Recovery mode, if you haven't already. Some reported it fixed their Download mode, others say it requires Download mode. Worth a try. See post #2.
Edit: Capturing the OTA does NOT require root, that much I remember. I seem to recall you just search through logcat file immediately after starting the OTA download. But again, I haven't done it myself.

Yea, I tried LG Bridge but I ran into the same problem as LGUP. When the phone reboots to enter download mode it freezes in download mode. It does the same thing when I manually enter download mode. I tried different ports, cords, pcs etc. all the same outcome.
However, I may be able to get ahold of another H932 so that I can possibly try my hand at capturing the ota link. I have to be more careful with this one, haha. It was never rooted or bootloader unlocked and I have no intention of doing that. Does it still need to be rolled back to nougat to rewrite the partitions if it was always stock? If so, then I would flash Nougat_h93210c_00_1017.kdz in Partition DL mode selecting all partitions, then flash Oreo_h93220h_00_0416.kdz (in Partition DL mode selecting all partitions again?) and then capture the update url when I get it via adb, correct?
The H932 handset that lost twrp and download mode was last flashed with one of the latest twrp flashable roms based on the kdz and not the actual stock kdz so I hope it still has a chance of working, but at the very least hopefully I can capture the ota url for some other's benefit.
That's a good plan, including the bit about being extra careful
I would first perform a Factory Reset (from Settings menu) while still in Pie. This will save you from FRP and possibly other issues. Then LGUP Partition DL back to Nougat 10d, using the latest Dev Patched LGUP from one of ChazzMatt's threads. Then reboot. If any problems Master Reset (Button Dance). Then LGUP Upgrade to latest Oreo 20s. Reboot.
Make sure you know what to do when you get the OTA offer BEFORE you get it.
I think there's a good chance you'll be able to salvage your other H932. It doesn't have to be completely stock for LGUP FOTA to restore Download mode. At least that's what others reported.
And posting that Pie OTA will be a great help for many people!
Edit: Of course there IS a risk to the unlocked phone. People have had issues going back and forth to Pie. Just saying...

Yes, I have taken a look at the steps to capture the link and they seem simple enoughto just use adb logcat while the ota downloads. But I just want to clarify beforehand... When I use LGUP to partition dl back to nougat I think I should be selecting all partitions, but when I go from nougat to oreo should I be using partition dl again and selecting all partitions once again? Just want to verify, thanks.

I had suggested the Upgrade mode for going from Nougat to Oreo, but you can do Partition DL too. In fact, that may be best since you're going straight from 10d to 20s. Yes, all partitions.
@ChazzMatt: You sometimes warn about going straight up to the latest Oreo. Any thoughts here? Particularly coming from Pie in the first place?

OK, so I flashed the stock phone and got to the point of running logcat. Nothing showed up in the logcat so I used the Take Bug Report method. I found two different ota file urls in the log. One of them was repeated more often so I think that is the correct one. However, I am unsure as to how I should proceed now. Do I need an .up file in order to use fota on the phone with no download mode? Did I perhaps grab the wrong zips? The zips appear to contain all the ota partition files. Trying to use the zip results in a "Windows cannot find WPDAPI.exe" error and an MTP is not running error. Granted this is the LGUP version that i just used to flash the stock phone successfully.
pressing the vol - before plugging in, it would show "download mode" for a spit second and go straight to fastboot mode. i cant do anything in fastboot mode since i cant get it to show on "adb devices".
i was just starting to root this V300L30p and managed to flash the h930 to unlock the bootloader. after flashing the unlock bin i waited and held the vol - button as said in the guide but the phone never boot up. i waited 30 mins or so. i tried to get to download mode and reflashed the h930 rom using dual mode LGUP partition dl but it didnt work and i just got "cant open port" i tried refurbish and it also didnt work. i tried master reset and it didnt work in trying to reflash. after a while i just couldnt access the download mode and it just goes too fast to fastboot mode.

In fastboot mode, is your Bootloader unlocked?
Can you run the getvar command?
What H930 KDZ did you flash? The right one?

OK if your Bootloader is unlocked and you have fastboot, then you don't need Download mode right now.
Install TWRP, root. Follow Section 6 of the WTF instructions.
Later after you restore modem you can worry about Download mode.

another problem arose. now in TWRP. wipe to format data, typed yes, and it returns with red text "failed to mount /system (unknown error 150)". same happens when i try to do a backup.
should i go to advanced wipe and change the file system of /system to others and then back to ext4?
edit: fixed by selecting ext4 in change file system. /system was showing 0mb, after redoing the file system it is now 14mb and able to be backed up

Try a regular Factory Data Reset from the Settings menu, if you haven't already. If the bootloader is locked and the phone never rooted (which it sounds like) it is unlikely that the actual ROM was corrupted - though or course not impossible.
What happens when you try to enter Download mode?
I tried to reset factory in setting and it had no effect. With reset data on recovery, it showed error message.
When i enter the download mode, it show 5 dots.
I have no idea to solve this issue

Are you saying you have TWRP (custom recovery) on your phone? With BL locked?
Factory Reset from Settings menu only works with stock recovery, and goes deeper than TWRP wipe.
If you have TWRP, you can use that to re-flash your ROM (as ZIP) and/or to re-flash laf (Download Mode, either as ZIP or as image).
Otherwise it sounds like Download Mode is there, but LGUP isn't picking it up correctly. I suggest starting over with LGUP. People often have the wrong version, since so many are floating around: Uninstall it completely, delete its folders, possibly uninstall USB driver as well. Restart Windows. Now install drivers and LGUP from scratch using the exact versions and installation steps from ChazzMatt's Pie ROM thread linked below:

If that still doesn't do it, then try different USB port, different cable, even different computer. Some computers are not compatible with LGUP.

Thank you for the update.
I wouldn't recommend that procedure you linked. That post is five years old, for a completely different phone (LG G2), using a KDZ extractor from 2014 which probably doesn't work with today's KDZ files.
I still don't see how your Download Mode could have been damaged on an unrooted phone. I think the problem is most likely your PC or your cable.
But that aside, I say it's time to rip off the bandaid: Unlock the bootloader and put TWRP onto the phone. It's easy on US998. Follow the guide linked below.

As we discussed elsewhere, however, he would need Download mode to go back to the early Oreo firmware is he wanted to bootloader unlock and root.
There have been reports of other people losing Download mode when updating to US998 Pie -- but those were people using the TWRP flashable zip. The fix was to flash US998 20e (Oreo) TWRP flashable zip and for some reason that restored Download mode. They could then try again to update to US998 Pie if they really wished. I haven't see that reported flashing with KDZ.
The fingerprint and camera issue is also reminiscent of a V30 that was on LOS-17 (which needs a permissive kernel). Even when going back to stock firmware, you still have to run permissive. The fix for THAT problem is to refurbish to Nougat stock firmware and then update back to newer stock firmware (last Oreo which is very stable or Pie which has some issues).
But he can't do that either until he gets Download mode back.
I really don't have any suggestions.
Thank you for pointing that out, @ChazzMatt!
@CuDem: ChazzMatt is completely right. I forgot you have to use Download Mode to roll back to 20b in order to use the WTF bootloader unlock trick. Duh... So that's not a path for you to fix this.
To me it sounds like this phone WAS previously BL unlocked and rooted, and that's where the problems with Download Mode began. Or LOS-17 was installed, causing the Camera and Fingerprint issues mentioned. Maybe the previous owner re-locked the bootloader and sold the phone, pretending it was in better shape than it was?
I can think of the following:
1) If you know the history of the phone and that it was never unlocked or rooted before, then I would still say it is unlikely that its laf partition (which contains Download Mode) was actually corrupted. The phone could still have been Frankensteined incorrectly or "abused" with LGUP, but because of very thorough integrity checking when flashing through Download mode, it would rarely cause you to lose Download mode. So if you KNOW it has never been BL unlocked, I would continue trying on a different computer, with different cables, different USB ports, drivers etc. If fastboot devices returns a serial number, that's a good test that USB drivers and ADB connection is working. But you could still have LGUP issues. Again, some computers (particularly some AMD processors) are simply not compatible with LGUP.
2) See if you can find the OTA update file for US99830b and force update it using LGUP FOTA mode. This works with the phone booted into the OS and MTP (file sharing) turned on. It may not complete the update since you are already on 30b, but it will rewrite laf (Download mode) as its first step. Several H932 owners have done that back in the Oreo days, and a few have done it on Pie. Study the thread linked below for the background and the procedure. But DO NOT use the files shared in that thread, NOR ANY OTHER H932 FILES. You will brick your phone if you flash anything H932 on any other model, or vice versa.
[H932][T-MOBILE] URL for the H932 Pie OTA file
https://forum.xda-developers.com/lg-v30/help/h932-url-h932-pie-ota-file-t3991417
3) Use Qualcomm 9008 mode and the leaked firehose to rewrite the laf partition (or the entire firmware). This is a more complex procedure, which I cannot help you with, but it allows writing almost anything to the phone, and should be compatible with all V30 models EXCEPT H932. See the thread linked below, and be ready for some hard work:
LG V30 Unbrick guide (Qualcomm EDL 9008 Mode, Hardbirck, with no download mode)
https://forum.xda-developers.com/lg-v30/how-to/lg-v30-unbrick-guide-qualcomm-edl-9008-t4048661
4) Contact the XDA member from Moldova who can repair your V30 remotely for a fee. His name always escapes me, but maybe Chazz or others remember. He is also on eBay:

https://www.ebay.com/itm/Remote-Ser...794311?hash=item46994ee187:g:gd0AAOSw0qFdJi7a
And that's all I can think of. Once again, please report the outcome back here, as it may help others. Good luck to you
Edit: Oh, and then there is Update Error Recovery on the Update tab in LG Bridge, which has worked for some to fix Download mode. It also runs from inside the OS (at least initially). But I am not sure LG Bridge works with US998, let alone on Frankenstein'ed phones. Still, it's easy, so worth a try.

Oh yeah, right. That's a good idea if you don't know whether the phone has been rooted.
I tired a search and the only similar thread i found was someone who was able to boot into twrp. I am not able to do that. over a year ago i rooted my phone. but i haven't had any issues. out comes this stupid update and my phone tried to install it and failed. since then I've had issues so i figured i'd just reset the phone. I go to pull up adb and adb will force my phone to reboot but does not recognize it after its in bootloader mode. Okay weird also will show my phone in adb when i type adb devices, and will force it to reboot to firmware update, but never sees it. Figured I'd start back at square one Load up the patched version of LGUP, it recgnizes my phone when its NOT in bootloader mode, but the second i try it in bootloader it doesn't see my phone. I've tried deleting the adb Lgup the device drivers i've revoked debuggin authorization I just can't think of anyreson other than so messed up firmware that the phone would be doing this

If you did it correctly, then that means you must not TWRP installed. If you had TWRP the button dance would boot to TWRP instead of wiping your phone. I hate doing the button dance as it takes specific timing to hit the buttons correctly.
In all my Guides there's only one scenario where I tell people they have no other choice than to use the button dance. In all others I stress other options.
I also tell people to never take an OTA update if you have TWRP installed.

Yeah I woke up to the "update not installed" nag screen...I know i had twrp installed since it's how i installed magisk, and the VS99630c .zip. Those are still on my SD card. At least after wiping the phone it seems to be behaving properly, but magisk is now gone and being unable to boot into twrp means I can't put it back. It's all good though it's a 3+ year old phone figured if i can't fix it i'll just replace it. Didn't know if anyone had an experience like this with lgup and adb not recognizing the handset in download mode. Seemed like a strange quirk...

Yes, sometimes reinstalling drivers helps. Also trying a different computer.
Your bootloader is still unlocked, but because you are on Verizon firmware it's not giving you the scary warning. To reinstall TWRP and Magisk, using Dev Patched LGUP you would have to temporarily flash back to US998 firmware (Oreo would be best), then use go through Section 6 of the WTF Instructions to install TWRP, reformat internal memory, install Magisk. Then you could re-flash VS996 30C (until a TWRP flashable zip of 30d comes along). You would need to freeze the update files so this doesn't happen again.

Yes i've been trying to just start back over at square one using the patched LGUP, but it doesn't recognize the phone. I've numerous cables and 2 different PC's and no luck yet. I am going to try and buy a new cable though since I just used the ones I've had around the house. Seems odd that the phone is recognized using the cables up until i place it into download mode though. Might try and clean out the ole charging port as well. Again i originally followed the instructions to a T and have had absolutely no issues but noticed i lost voice commands and my sms/mms were messed up, immediately after the failed update. the phone seems to be 100% now with no issues due to the wipe. SO it's not the end of the world if I can't figure it out, but more like a challenge of fixing it
If someone can capture and share that OTA update you received, you can flash it using LGUP in FOTA mode. This often restores a broken Download Mode, even if the system update itself fails due to the phone not being stock and/or lacking stock recovery.
LGUP FOTA mode works inside the OS (with the phone in File Transfer mode) and doesn't require working Download Mode.
Just a thought
Caveat: The purpose of this would ONLY be to fix your Download mode. However there is a risk it might actually mess up your OS (which is currently working). So if it doesn't fix your Download mode, you'll actually be worse off.
I have the exact same issue so you're not alone, I'm trying anything I can think of, lmk if you figure something out. It's weird it sees phone in desktop with phone booted then a glitch in download mode and it never pulls up. I'm due for a new phone anyway, the update slipped thru somehow, lost root and twrp, can't flash. I'll let you know if I figure it out as well. If Chazz don't know how to fix itwe might be out of luck.

Which model do you have, and which ROM are you on?
If you are "somewhat stock", on a model for which we have OTA files, you can force flash those using LGUP FOTA mode. This works inside the OS, doesn't require Download mode, and will often restore Download mode as the first thing -- even if the update itself fails because the phone isn't completely stock.
If you are on T-Mobile H932, we have a separate thread to help restore Download mode using OTA files and LGUP FOTA mode:

You're in luck then: If you're on Verizon 30c, it *should* offer you a 30d OTA update. And if you accept that, it *should* repair your Download mode as part of the update
The potential risk here is when you're not completely stock, the OTA probably won't complete. That's ok as long as it repairs your Download mode, since then you can re-flash with LGUP. But in case it *doesn't* repair your Download mode, you could theoretically be worse off. I haven't heard of cases where that happened, I'm just pointing out the potential risk.
Good luck to you :fingers-crossed:
Edit: No wait, if you started out as LS998, Verizon won't offer you the OTA. But I believe somebody captured the 30d OTA file and shared it in another thread (about the 30d). If so, you can force flash it with LGUP FOTA mode. Make sure the PC can see the phone as MTP (USB File mode) before attempting this.

Doin' the buttons in DL mode.
So, I've been having a lot of stability issues on my phone which has been running on a ROM which I flashed back in December of 2019. I'm fuzzy on the details of just what I did back then, but according to Software Info in About Phone it's a Pie ROM, Software Version US99830b, build PKQ1.190414.001.
I haven't had time to follow the LG V30 scene at all since then, and likely won't be able to keep up with it in the future either. So for the sake of stability when I reflash it this time, I don't want to bother with having Root or anything fancy. I have a vague recollection of some LG bloat/spyware that was important to remove for performance/battery life, but aside from that, I just want a stock experience this time around.
Coming back to the forum, I saw the thread about carriers, VoLTE, and ROMs, and while I'm not sure I've absorbed all the important details about that upon reading through it, that's going to be a concern for me as well, so I should mention I'm on T-Mo and plan to be for a while.
So I was wondering if anyone could please point me in the direction of just what steps I should be taking this time around?
Temporarily flash back to Nougat US998 KDZ to erase the effects of Pie.
Then flash to last Oreo US998 20h which is very stable. (I'm on rooted last Oreo US998.)
Use "Refurbish" or "DL Partition" to flash the KDZ. Then you no longer have root.
Your bootloader will still be unlocked. If you want to lock it back, follow these instructions. Do NOT relock the bootloader until you have re-flashed the full KDZ and no longer have TWRP custom recovery. You have to be back 100% stock (even recovery partition) to re-lock the bootloader without bricking the phone.
Personally, I would not do that but at that point (on US998 20h) just reinstall TWRP and Magisk and remove the LG spyware.

You are using the Dev Patched LGUP? Also, which mode -- Refurbish or Partition DL (all partitions)?
Using tecknight's dual mode LGUP, in Dev Mode, and I get the SPC Code error message with Refurbish, and with Partition DL, as well as with other options like Dump, or Phonesetting. (Did not try it with the DO NOT TOUCH options like Chip Erase.)

Good you didn't touch Chip Erase.
Yes, Dev Mode is correct with tecknight's dual mode LGUP.

No success with the .BAT, or on the other computer in my household. Still getting "Error:SPC Code does not match. Please, try again." at the 4% mark.
