Hello all,
I have a Verizon LG V30 that I converted to a US998 LG V30 using the Frankenstein method. Today, I clicked the Uninstall option in Magisk Manager and the device uninstalled it and rebooted. Upon rebooting, I was thrown into Fastboot mode with no way to get out (No Recovery, nothing.) I tried resetting through Fastboot to no avail. It still connects with Fastboot but nothing else. I can flash firmware with the patched LGUP but no file I have tried has worked. Is there anyway I can flash my V30 back to Stock VS996? Thank you.

Why isn't there a way to get into Recovery? Use the same fastboot commands you got into recovery the first time you installed TWRP. You can even use those commands to boot to TWRP on your phone even when TWRP is not installed on your phone, via "temp" TWRP.
Since you uninstalled root, you can't use the Reboot Recovery app anymore -- as that requires root access -- but you can still use the fastboot flash commands.

Yes, go into Download mode manually and use dev patched LGUP to flash VS996 Oreo KDZ with DL Partition method. Flash all partitions. Not sure why you are doing that however. You decided you don't want to own your phone anymore?
People who want to KEEP root and TWRP and go back to VS998 would use DL Partition method -- but UNtick the partition recovery partitions. Then you would still have VS996 but with TWRP. You would no longer have fastboot flash commands, but you would still have TWRP custom recovery. Then you just flash Magisk root. So you would have VS998 with TWRP and root.
And at that point you could even use the reboot recovery app with root to always easily get to TWRP.

Thank you very much. I am booting up my ADB and Fastboot to flash TWRP, as I still at least have an unlocked boot loader. I’ll download a Oreo KDZ for the Verizon Variant if that doesn’t work out. Do you have any sources for one on the forums? Thank you!
EDIT: Once I get into recovery, should I flash a stock ROM? There are a few on the ROMs section of the forums but I do not non which one to download.

1) Do your want to keep TWRP and root and just flash back to VS996 (while keeping TWRP and root)?
2) Or do you want to just keep TWRP but you don't want root right now?
If #1, once in TWRP, reflash Magisk.
Then reboot, and go into manual download mode BEFORE opening the patched LGUP. Then Frankenstein back to VS996 with DL PARTITION method, but untick (uncheck) the recovery partitions. Then you'll be back to VS996, but still have TWRP and be rooted.

Don't mind my other comment, I fixed what was going on there for the most part. I have tried 2 different firmware files and both of them will not boot. The Official LG Boot image (flashable with TWRP) flashed with no errors, but i just booted into download mode again. I also flashed LineageOS and the same thing happened. I tried the Refurbish and Upgrade option through LGUP and both stopped at 19% with error 0x2000. Do you have any suggestions? Thank you.

I did a data wipe accidentally in TwRP. Meant to just get cache. Now I lost root/TWRP apparently. Just recently updated to 20c. I have no recovery when I reboot but I still get the unlocked bootloader info when rebooting. Any ideas/help is greatly appreciated.

I don't see how wiping data would remove TWRP, but the way I'd reestablish TWRP once it's gone would be to LGUP the Tungkick 10d tot file and then use that TWRP to flash the 20c zip by Autoprime. Flash SuperSU one way or another and then have a blast. I'm sure there are other ways to accomplish all this, but this way is easy and has been reliable for me.
It seems that you can still boot the phone.
If you still have valid bootloader the issue is not that tricky.
Just do a "adb reboot bootloader" and reflash twrp, like how you installed them in the first place.
I'm not sure which exact version of twrp is compatible with v20*, but that should be easy to find anyway.
Then boot into twrp and flash supersu/magisk/any other thing you need.

So I did a factory reset from the settings menu. Now it boots back into TWRP. Weird. But that's it. No OS. Just the recovery. So I guess I'll try and flash a ROM and see if I can get that back. Thanks for trying to help.

Yeah, as long as the ARB is the same (ANTIROLLBACK 01) you can flash 10 after 20. I don't think 10a qualifies, but 10d should be okay from 20a or 20c.
It's a quirk of the G5 that TWRP can only be accessed from boot by factory reset of the phone. If you are already up and rooted, you can use a command or program AFTER boot to access TWRP without factory reset. But, for now, that's our doorway into TWRP from power-off.
Now that you're in TWRP you can sideload a ROM onto your SD and flash it, just remember to also flash the latest superSU zip afterward to ensure root (unless your ROM is pre-rooted.)
Hi,
I have a rooted LG G5 H850 with an unlocked bootloader and TWRP. I was on H850 20A OPEN EU ROM from autoprime and I tried to flash H850 20D OPEN EU ROM. I booted into recovery TWRP and flashed the Zip file together with the newest SuperSU. When I tried to reboot the phone stuck in reboot - always changing between the message "Your device software cannot be checked for corruption" and the LG logo. After a long time (15 minutes or so) I pulled the battery. The same thing. Then I tried to get into recovery using the 2 hands method. I clicked through the factory reset screens (yes, yes...) - and the phone stuck between warning screen and logo again.
Could someone help me to get into TWRP again? If this would be possible I could restore my backup. Otherwise I don't what to to else...
Thanks for any helP!
Ok, after several tries with the 2 hand method, I got into TWRP again. I tried to restore my backup but it failed with an error. After that I did a full wipe (factory reset) but without the internal storage. Then I flashed the 20D zip again, after that SuperSU. Now the phone is rebooting and rebooting and rebooting. It is stuck on the LG logo and nothing else is happening. It's frustrating...
Firmware reset > flash zip file.
If that doesn't work use the LGUP or LG Bridge method to flash firmware. There should be threads in the development section

Thanks for your help, but I don't use windows. But in the meantime I got it solved. The reason for the failure was a corrupted external sd card. Flashing from a new card did help.
i'm getting the same problem with the OREO OPEN EU ROM, booted into TWRP, flashed SuperSU and after a few loops got stuck on the LG logo. Had to pull the battery, go into download mode & reflash the ROM via LGUP. I somehow doubt it's the SD card as there were no errors on the SuperSU install.
I bought a LG V30+ from ebay which had Magisk installed but its a system app. I updated Magisk to 18.1 unknowingly it would screw up. I tried to install Magisk through the Manager but unable to unpack the boot image.
I would appreciate any of your help.

Boot to TWRP, uninstall Magisk using the TWRP Magisk uninstaller.
Google it.
Then reinstall Magisk in TWRP.
Clean caches before rebooting.
You can download both the Magisk uninstaller and Magisk itself on PC and transfer over to phone while in TWRP, connected to PC.

You can root without TWRP, but it can cause problems. You can't make backups to restore, you might accidentally install OTA updates -- which could brick the phone (which having TWRP custom recovery won't allow).
If you install TWRP the way I recommend, yeah you'll wipe data. On purpose, because you'll disable LG's nosy root checker file (none of their business if I have root) and disable LG encryption. (Then you can enable TWRP encryption if you wish.)

Seems like the best way is to just backup everything I have and install TWRP normally. Is there anything else I should know before doing such a thing? I have the US998 variant btw.

That's about it. Your bootloader is already unlocked, so you don't need to downgrade back to US998 20a or 20b.
What software version are you on? 20-what?

Very old. We're on 20H now with lots of fixes, improvements, DTS 3D stereo. You can upgrade via TWRP flashable zips once you get everything straightened out.
Also strongly consider installing this V30 Magisk mod:
[Magisk Module] AnxiousV30 (v224)
Works with rooted stock firmware, specifically North American variants. Best with US998 and VS996 but can work with others.

How did you try to boot to TWRP? If you try through the hardware buttons (called hardware button dance) you'll get that until you mash the correct yes buttons. But that's not how you should boot to TWRP unless in case of emergency. Instead you should use the fastboot boot command. It's in my WTF instructions. You did read that, right? You have to boot straight to TWRP after installing or TWRP will not stick, and you have to make it writable before booting back to your OS or TWRP will not stick.
Then after root, you install the Reboot Recovery app and give it root privileges.

Ah now I know what I did wrong. Finally got Magisk to work again. I absolutely forgot the fastboot boot command. Thanks man, I really appreciate all the great help.
I might have done something stupid, would really appreciate it if you folks can help me get back to US998 Oreo.
I installed VS99630c (Pie) on my phone, via TWRP. After this the bootloader warning disappeared, so I suspect my bootloader has been re-locked. I can’t access TWRP anymore, neither from factory reset, nor from ADB commands on PC (the phone just reboots normally). I can’t get to fastboot either. However I can access Download Mode.
How should I proceed?

No, your bootloader is not re-locked. The Verizon firmware does not have a bootloader unlock warning. Verizon never thought they would need one...
You don't have fastboot flash commands on Verizon firmware. That's why you needed to temporarily convert to US998 to bootloader unlock and install TWRP.
To boot to TWRP, have you tried to use the Reboot Recovery app I STRONGLY RECOMMEND in all the Pie KDZ threads? Or boot to TWRP from Magisk Manager? If you have TWRP, either work unless you've wiped out TWRP.

No, I guess Magisk didn’t flash. Downloaded the Magisk Manager app and it says “Magisk is not installed”. Should I click on install? I figure that may be risky because I’m not sure I have TWRP.

At this point in time you need Magisk installed. You can only install in TWRP.
At this point in time, you have two options:
1) try the "hardware button dance" again to see if you can boot to TWRP. If you get to TWRP, flash newest Magisk.
If you can't do that, you will have to:
2) use Dev Patched LGUP via Refurbish mode to flash back to US998 Oreo KDZ, to get back fastboot flash commands. Your bootloader is still unlocked. BEST to flash back to US998 Nougat via Partition DL, Master Reset, then US998 Oreo. Since your Bootloader is already unlocked, you can go to US998 20h after Nougat.
Then, go through WTF Section 6 instructions completely to re-install TWRP and the three root files. Do not skip any steps of that section.
Finally, re-flash VS996 TWRP 30c flashable zip and this time flash Magisk before rebooting.

After failing to boot to TWRP, I've been attempting the LGUP route but no matter what I try it doesn't recognize the device (it says "There is no handset connected"). Here's what I've done exactly:
Deleted old LGUP from Program Files
Followed all the instructions here in the section "HOW TO INSTALL DEV PATCHED LGUP": https://forum.xda-developers.com/lg-v30/development/vs996-lg-v30-vs99630a000704arb00-kdz-t3952254
Didn't work so tried again (different USB ports, used a different computer, reinstalled drivers, reinstalled LGUP, used different cable, even used different Dev Patched LGUP, etc).
LGUP recognizes my device just fine when it's booted normally, but in Download Mode there's no connection
After trying all kinds of stuff for the past few days I was just about ready to throw in the towel. Must have gone through a hundred threads on this forum.. finally I came across someone with a similar problem who fixed it with his Windows 7 PC. Found my old laptop that’s over a decade old and booted it up. Installed the drivers, LGUP, etc. Booted up my phone in Download Mode.. still no connection. Reinserted usb cable.. and the damn thing finally showed up. That ancient behemoth of a computer managed to save my phone
Thanks a bunch for helping me out Chazz

Same here. Can't access fastboot, and the patched lgup doesn't says "no handset connected."
It's as if bootloader mode and recovery have become the same thing.
Stock US996 twrpable zip firmware for the lg v20 is here. My phone is already rooted with magisk, bootloader unlocked, and has twrp installed.
I formatted my phone using twrp, and rebooted into recovery mode. I then flashed the US99610P firmware (as it is the most up to date in the list at the time). As soon as I reboot into the system, the "phone is corrupt and unable to boot" warning pops up and it's now in an endless bootloop.
I have flashed VS996 12A firmware with lgup patched to get the phone back to a working state.
TLDR: bootlooping lg v20 in part due to the US996 firmware. How do I flash US unlocked stock firmware on this device through twrp?
Flash it with partition DL using patched lg up. You can't just crossflash the vs995 to us996 with twrp due to the different partition layout. And this is not the correct section to post this in.

I did. Flashing using lgup patched works fine when on stock firmware. The issue is when I'm rooted and have twrp installed.
This happened as well when flashing custom roms as well.
