I have a US998 running the latest Verizon Oreo 20k. It tried to update to Pie but failed and since then, I've lost all fastboot commands. Prior to this, I had TWRP, and an unlocked bootloader. Now, it seems by bootloader is locked, and I cant get into download mode and downgrade with any .kdz via LGUP. Any suggestions?

You never had no fastboot flash commands while on Verizon firmware. You only have fastboot flash commands while on US998 firmware. That's why you had to temporarily Frankenstein to US998 to unlock the bootloader.
Why did you try to update to Pie OTA while you had TWRP custom recovery? OTA is ONLY for phones with full stock. We tell people over and over they will NEVER take OTA unless back in on full stock firmware.
Most people with TWRP freeze or disable the annoying OTA bags which are useless to them.
You should have waited for the TWRP-flashable zip that's coming...
Yeah, hindsight is 20-20. I installed stock 20k Verizon firmware, and took the OTA update. Wanted to play with Verizon's Pie for a bit. The update downloaded, but on rebooting, it failed. So now I'm still stuck on Verizon Oreo, no fastboot commands, unable to use LGUP to flash any .kdz. Lesson learned. Perhaps the guy on ebay can remote fix this.

You didn't install full stock firmware if you flashed with VS996 TWRP-flashable zip.
If you flashed full VS996 KDZ via Dev Patched LGUP, then yes that's installing stock firmware. And that would have wiped out TWRP, and safety allowed you to update with OTA.
HOWEVER, you would have no fastboot flash commands and no way to reinstall TWRP. You would then have to Frankenstein back to US998 for that.
Good news is your bootloader is still unlocked. You never locked it back. You just have no fastboot flash commands.
You've tried to manually go into download mode before opening Dev Patched LGUP?. Just asking.
(My hindsight isn't 20/20. I could have told you this would have happened if you'd ask questions. We tell people over and over not to try to take OTA after they install TWRP.
1) We have something better than crappy partial image OTA. We have full image KDZ and then TWRP flashable zips based on full image KDZ.
2) They will mess up their phones taking OTA with TWRP custom recovery installed. I'm sorry you didn't read the warnings.)
I don;t think anyone could predict that an OTA would wipe out download mode. Plenty have taken the Pie update without this happening. For ****s and giggles, I wanted to try Pie, and for me, the best way to do so was to do it via OTA on a fresh stock kdz. I didn't mind, as I can (could) easily get TWRP, root,etc back. However, the OTA didn't install (Verizon's fault?), there was an update installation error. I gave up, tried to kdz back to us998 like I've done successfully a bunch of times. But LGUP can't install any kdz because I lost download mode. It just gets to 4% and reboots back into the OS. I have a feeling my LAF is corrupted. Taking an OTA from Verizon that is meant for millions of phones shouldn't cause this sort of trouble but it did. I lost my ability to revert changes.
It appears the only way to get download mode back is to do it remotely via test points. Arghh.

So you did flash full VS996 Oreo KDZ? You had already gotten rid of TWRP prior to taking the OTA? I thought you had flashed V996 Oreo TWRP flashable zip and tried to take OTA with TWRP custom recovery still installed.
Then other than the crappy partial image OTA, I don't know why it didn't work.
Are you able to go into download mode manually before opening LGUP? If so, what I would suggest is re-installing Verizon Oreo KDZ via Refurbish mode to clean things up. Make sure you are using the NEW Dev Patched LGUP found in the Pie KDZ threads, not the older one found in the Oreo KDZ threads. The older one doesn't work to downgrade from Pie. Even though you didn't successfully update to Pie, something about your system may have changed.
Then after successfully reinstalling VS996 Oreo KDZ (if successful), then go full blown Frankenstein to US998: US998 Nougat, Master Reset, US998 Oreo.

See that thread. They recovered.
Unfortunately, I have somehow lost download mode, so LGUP will never work. Is it possible for an OTA to inactivate download mode? If so, that seems pretty shady, but not unlike Verizon. If Verizon is inactivating download mode, they're being selective (maybe by IMEI?) sonas not to be obvious about it.
From what I understand, the LAF partition is associated with download mode in LG phones, is it somehow possible to restore via LGUP an LAF image or whatever format that's in and maybe get LAF partition back?

Hey XDA, I'm having a bit of a problem. I got my G5 just recently and I wanted to go ahead and unlock the bootloader so I could install some custom ROMS (I'm not a fan of LG's ux), but I ran into a sticky situation. I was trying to flash the TOT file for rooting h830 with LGUP when I found out that it doesn't work on Nougat. I tried to cancel it but now I'm just stuck in firmware update at 0%. The code at the bottom says 633A B50. I can get into fastboot but I can't really go anywhere from there and I've gotten to stock recovery but all it does is factory reset and boot me straight back to firmware update. I downloaded the stock nougat kdz file but LGUP won't flash it; sometimes it says invalid, other times it gives me the error code 0x2000 CEFS::Initialize. This is a brand new (kind of expensive) phone and I can't send it to LG for repairs since I unlocked the bootloader and probably voided warranty so I'm really desperate for a solution. Can anyone help me out?

Was your phone on the 20a version before you tried flashing the 10d root tot file and did you actually cancel the process within LGUP while it was flashing the phone?
Another user had a similar problem but he flashed the 20a version before he accidentally flashed the 10d root tot and he fixed it by just flashing the stock 20a within LGUP.
Assuming you can still get into download mode you should be able to fix your device.
Try flashing this kdz uploaded by @autoprime
downloads.codefi.re/autoprime/LG/LG_G5/H830/H83020a/H83020a_00_1107.kdz
If flashing is successful factory reset your phone from the stock recovery after.
Thanks, that worked but I had to do a little tinkering before it did. LGUP wouldn't flash it because it kept saying invalid and some other random reasons but I found a program called uppercut that allowed it to flash. I was able to get back to stock and then I used the dirtycow exploit to flash TWRP. All's good now on XenonHD.
so I thought I had a grasp on the unlocking rooting myself. I was getting the error in lgup where it doesn't recognize my device at all. I unlocked the oem and it did its own flash afterwards then I had to go and reset unknown sources. then I tried to do the lg up flash assuming all I needed from my 20i was the v10d arb01 may 23, I picked the upgrade and in the middle of it it failed. then it rolled back. so I tried it several more times in lgup and it failed so I tried the arb 01 march 4 with full root and it failed.
Edit: okay lI found uppercut and it reconnected me to LGUP then I used the flashable 20a file and that patched me right up. But no root, I can do a 1 click now I guess but what about a flashable twrp or can I just install it like the old cwm or x-parts? where to now? do I try the 10d one with root? I'm really tired of looking and blindly downloading tot and kdz files hoping they work? My main goal is to slap RR remix on this for anyone that would give me a hand
I picked up a new in box factory unlocked LG V30+ (LG-US998) on Amazon pretty cheap in December. What I didn't realize it that it is just running android 7.1.2 not 8 which I believe is the most current version available. I bought the unlocked version to avoid all the AT&T bloatware, but now I'm realizing it won't update OTA to the newest OS and is probably behind on security updates. Does anyone know what I need to do to get the phone to update OTA. I'm not interested in a custom rom or any of that, so if that means I need to flash the AT&T stock rom (with their bloatware) that's fine. I just want the phone to get OTA updates. I tried using the LG software to update it and it doesn't recognize the phone.
Refer to these two threads. Read through them, ignore the part about rooting if you won't be doing that.

You just need to update to latest US998 KDZ via software called LGUP.
See link below. You want steps 4 and 5.

Yes, those instructions are for converting to US998 -- but steps 4 and 5 still apply to someone just wanting to update US998 to most current firmware.
Install LGUP, download latest US998 KDZ (links provided), flash via Update mode. Easy.

I had this same issue with my phone... Wouldn't ever get OTA updates... Honestly, the easiest way to get updates outside the kdz and lgup is to use the twrp stock builds. They're stock V30, you can get them without bloatware (US-998), and updating them is a piece of cake once you know what you're doing... In my case, the lack of updates seemed to have something to do with the fact that my device was somehow a Sprint device, blah blah blah....
Anyways, TWRP stock builds is the way to go... I'm currently running the Tmobile stock build and it's fine and does whatever I need it to... I like it better than custom

I agree TWRP flashable zip is fantastic. I use it, but for my wife's phone which is not bootloader unlocked or rooted (and my sister's phone also), the LGUP/KDZ method is where they need.

I hate to resurrect such an old post, but I never got around to doing this. Now that the quarantine is in place I have time. Is there a newer version of the kdz that I should use (probably Pie)? I'm guessing there's a newer version of LGUP (modified) as well?
Let me make sure I understand this too. I can use the modified version of LGUP to flash the newer kdz to my phone using the "upgrade" option and it keeps all the data currently on my phone, right? If later I wanted to do a factory reset on my phone, that would wipe the data but still retain the newer kdz that was installed, correct?

For US998, I only recommend updating to last Oreo 20h. I'm rooted, still on that. My wife, mother, sister, brother in law who are all NOT Bootloader Unlocked/Rooted are all still on that, also.
The one US998 Pie KDZ we received is very wonky. It's technically for U.S. Cellular. LG never released Pie KDZ for Open Market. Charging is slower, other things broken if you use other carriers.
Many people find it hard to update to, and if you have problems most of the workarounds depend on having TWRP.
I strongly recommend stable last Oreo 20h.
Yes, there is newer version of Dev Patched LGUP. I have it posted in the US998 Oreo and Pie KDZ threads, as well as Frankenstein.
Yes, if the use Upgrade mode you keep your data as long as you are already on earlier same firmware, in this case US998.

It will put you on early Oreo Sprint firmware with stock recovery. You can then take all the OTAs back to current firmware. However you will still have unlocked bootloader.
(The only way you can lock bootloader is to flash to firmware with fastboot flash commands, like US998. And then leave it there.)

Just to emphasize... Without TWRP and root, Sprint will again own your phone. You can't install wonderful stuff like Anxious V30 mod.
You'll no longer be able to make and restore TWRP backups nor Titanium Backup.

I have an unlocked AT&T V30 H931 that I've been using on Verizon with a stock Verizon Oreo ROM. I got a prompt this morning saying System Update 14 was ready to install, so I accepted the update. It proceeded to update until it got stuck on the white Verizon boot screen with the animated dots. I left it here for a while in case it would eventually make it past this, but I gave up after 90 minutes.
I can reboot, go to download mode, bring up the recovery menu, reset, choose safe mode - none of these change anything. Whenever I try to boot, it just hangs at that screen. I've tried using LGUP to revert to the Oreo ROM I had, but I get an error with that. To top it all off, my brothers have the same phones and ROMs and they're in the same boat I'm in after accepting this update.
So, what can I do at this point? I thought maybe I could install Pie via LGUP, but I haven't been able to find a place to download the appropriate files from.
Use newer Dev Patched LGUP that can handle Pie (some stuff changed before aborting, so you may have partial Pie).
Go into Download mode manually, Refurbish to most recent Oreo KDZ.
Master Reset.
See Instructions in post #3 of this thread, about downgrading to Oreo...
https://forum.xda-developers.com/lg-v30/development/vs996-lg-v30-vs99630a000704arb00-kdz-t3952254
Use the newer Dev Patched LGUP from that thread. Uninstall any prior version. Read the installation instructions.
______
Then wait for Verizon VS996 Pie KDZ to be released publicly.
Use same newer Dev Patched LGUP to install that, when available.
Great, it's working with the dual mode LGUP. Thanks!
Do you know why the OTA upgrade didn't work? I haven't had any trouble with previous OTAs, but of course this one is installing Pie.

You aren't the only one who got bit by this. There's another thread going with almost same circumstances. Originally I thought he tried to install OTA with TWRP custom recovery still installed, but he was full VS996 stock (from US998), and he knows what he's doing.
No, I don't know why -- but I'm very distrustful of any partial image OTA updates. Learned that from Droid Turbo forum. I always prefer to manually flash full image, as it gives me more control.
Full image Pie KDZ for VS996 should be released publicly any day now.

Ok, I see. I'm making a mental note to wait for KDZ releases in the future.
One more question: my brother's phone, which has the same issue, has data on its internal storage that he hasn't backed up. Is there any way to downgrade without having to wipe the internal storage or perform a reset?

Probably won't work, but using Dev Patched LGUP he can TRY to use "Upgrade" mode to go back to most recent Oreo. It's not really Upgrade but if successful, it would keep his data.
If that doesn't work, then he needs to use Refurbish mode.
You're lucky, I lost download mode and the ability to LGUP and kdz. I've never had any problems using an OTA update when on stock firmware but I sure as hell learned my lesson. I feel sorry for those poor people that don't understand these issues and just take an OTA update because they don't know any better and lose features on their phones. Perhaps ignorance is bliss.

So you lost download mode after an OTA update? Just trying to understand whats happening here.
Yeah, on stock Verizon firmware, update restarted the phone, booted to a failed update screen, then back to the normal OS. But I don't see my unlocked bootloader warning screen anymore, and when I tried to use LGUP, I found I didn't have download mode anymore, so currently unable to flash any kdz.

What about TWRP?

Lost that, too. I've never had an OTA jack my phone up so bad, it's like it erased the LAF partition. My only option it seems is to use an Octopus Box.

Do you have stock recovery now?

I have nothing, if I try and adb into stock revcovery, I get a "no command" error, and no button combos can get me past that. Eventually, it just boots up normally.

I remember having similar instance of flashing one of the Verizon roms that I lost download mode too. I had to flash a us998 rom to fix it..

How do you flash without download mode? Did you have TWRP?

He's on stock firmware, so no TWRP.

You still have unlocked bootloader, but Verizon firmware doesn't have unlocked bootloader warning.
Some people in the past would flash parts of Verizon KDZ to get rid of the annoying bootloader unlock warning. But that's dangerous to mix and match.

So he probably flashed a stock rom, and hopefully flashed magisk, he'll have root. He can possibly recovery twrp with Flashify.

He Frankensteined to full stock VS9996 to see the Verizon Pie OTA. It didn't successfully install. He somehow lost Download mode and doesn't have fastboot flash commands -- since he's on VS996 firmware.
He DOES still have unlocked bootloader, but it can't do any good without being able to Frankenstein back to US998. He needs Download mode for that, to use Dev Patched LGUP.
If someone can capture the OTA .up file, couldn't that be installed with LGUP in FOTA mode? If the update succeeds, it should restore LAF.
I understand that's what H932 users who lost their LAF do to restore it. Haven't tried it myself, just pointing it out. Check the H932 lafsploit root thread for details.
Heck, try updating with LG Bridge. If it works, great, otherwise it should at least provide the OTA file. Again, as I understand, haven't tried myself
Edit: Even better, don't try to install the Pie update, but rather install the last security update with LGUP FOTA mode, if you can find the OTA file. Again, that's what H932 users do to restore a lost LAF partition.
I have an AT&T V30 that is unlocked and running US99820E, and I am trying to flash the Verizon PIE FW (VS99630c_00_0902_ARB00) via LG UP. I have tried using the refurbish, upgrade, board DL, and partition DL options in LG UP.
After I flash the Verizon FW, when the V30 restarts it stays at the Verizon logo with the four dots.
I can flash back to the US998 FW via LG UP, but I can't get the Verizon Pie FW to work.

You have to use Frankenstein method to cross flash North American variants when using full image KDZ.
(And even Frankenstein does not allow T-mobile H932, due to different RSA encryption.)
You can't just cross flash Oreo and Pie KDZ back and forth. There's a method you have to use, where you first flash Nougat of that new variant, Master Reset (not Factory Reset) -- then you can update from there. That's how you got from AT&T firmware to US998 in the first place, right?
See the Frankenstein instructions.
Yes, it's different if you're using TWRP flashable zips to cross flash.

Thanks for the reply, ChazzMatt!
At what point in the process would I flash the Verizon Pie KDZ? Would it be after Step 4, flashing the Oreo US998 in Upgrade Mode? And do I flash the VZW Pie KDZ in Upgrade or Partition DL?

1) From US998 Oreo (you're on that right now, correct?), flash VS996 Nougat via Dev Patched LGUP in Partition DL mode.
2) Master Reset (which is not Factory Reset).
3) Then flash VS996 Pie in Partition DL mode. (Upgrade mode might work. But try Partition DL mode first.)
___
Alternatively if you had unlocked bootloader and have TWRP custom recovery, then you could install the VS996 Pie TWRP flashable zip straight from US998 Oreo.
___
Are you a Verizon customer? Is this why you want VS996 firmware? You have an already-activated Verizon SIM card?
Anyone resolved this?
I am having the same problem. Just switched from AT&T to Verizon. I followed the Frankenstein method (1. Flashed VS996 Nougat, 2. Master Reset, and 3. Flashed Pie using both Refurbish and Partition DL mode); both gave me the same result. After the red Hello, I get the Verizon with four animating dots @ full screen brightness. I let it sits for 30 minutes and nothing happen. I repeated the steps above and replaced step 3 with Oreo and it works fine. Then I perform an OTA update. Update 13 was applied okay, but Update 14 included Pie and after installing the update and reboot; it is stuck on the Verizon screen again. I also tried US998 Pie and it had the same problem.
Anyone has any idea on how to fit it?
