Make sure you are using the Dev Patched LGUP from the Pie KDZ threads. Uninstall any prior version. Read the Troubleshooting Tips in the Pie KDZ threads just below the Dev Patched LGUP installation instructions.
I fixed my problem by flashing US998_20E and it fixed my download mode which appeared to be the problem
Thank you

Hmm no link??? I have the same issue, it all worked and I was going to downgrade again to version A7 and then out of the sudden it does not work anymore. SIGH, so sick and tired of this nonsense.
Whatever it took, I downloaded something which seemed to work and I have downgraded to version 7 - sadly I seem to have lost the link. But here are the files for installing it, first install the msi file and then copy the things in the folder LGUP_pie to the place where it was installed and override anything. And it should work.
So now my F800K is now again running A7, downgraded from A9! Back to looking into rooting and fixing boot loader.
install msi file and copy the things in folder pie into the installation and override it. At least it fixed my issue and downgraded from version 9 to 7.
Just go to ChazzMatt's Stock KDZ thread for your model. It has all the links you need for the correct LGUP version AND the KDZ file AND anything else you're likely to need. PLUS exact steps to install LGUP and perform the flashing. Oh, AND troubleshooting steps in case you have problems.
It's true, it DOES require that you go to the V30 ROM section and click on the thread for your model

So I've installed LGUP to flash the h850 v10e unlocked kdz as I'm getting nowhere with the fluency HD 24 patch. Now that I have LGUP installed I put my phone into MTP and that's when lgup finds my device but when I click on select I get an error saying 'LGUP can't load the model[C:\program files (x86)LG Electronics\LGUP\model\com

Again ? Please take the time to read through the forums. EVERYTHING that you need is here.
Try for yourself, XDA is a development site foremost(although it is also a friendly environment...mostly), if you still have difficulties and you have tried out all the options/possibilities.. then ask for assistance.
I am far from any Android expert but i have always taken the time to read, read again and try to understand what i am about to do/flash etc and MOST importantly.. know how to get out of any possible mishaps.
Taking the time (yes it's boring) will help you in the long run.
you will need to install the model dll

this looks like downgrading from Nougat to Marshmallow may be blocked on the H831 when using LGUP.
as shown in the screenshot.. your phone is on Nougat (20A) but you are trying to flash a Marshmallow KDZ (10D).
Obtain the 20A (or higher) KDZ for your phone model and that should flash in LGUP.
An alternative to flashing the KDZ would be trying to run a factory reset (wiping user data). You can do this from the settings menu on your phone.. or by booting into stock recovery menu. The G5 All-n-one thread on XDA has steps for how to boot into recovery if unsure.
Some users have stated that they have been able to downgrade from N to M with a combination of LGUP 1.14 + UPPERCUT and LGUP 1.11 and DLL MSI. There are downgrade threads in the G5 section here on XDA for more info on that. Not all models support this downgrade though (even though anti-rollback isnt set). You could technically root the phone then manually flash each and every partition to downgrade but thats risky. But to anyone capable and knowing how to do that.. yes that would work as long as you aren't downgrading fuse version.

hi v10 folks,
just bought this v10 mobile 3 days before. it came with 5.1 android version, so thought of upgrading it and found some weird observations.
1. on connecting mobile to LG Bridge, model shows as H901 but update shows as F600S30D :crying:
2. downloaded lg phone info app and saw the provider name as SK Telecom
i have attached three screenshots of my mobile phone. is this a genuine t mobile version ? what needs to be done to upgrade my phone to Nougat ??? instead of bricking my phone thought of taking your suggestion guys
thanx in advance
Do NOT use LG Bridge, or you will brick your phone. Dunno where you got your phone, but it has an F600 IMEI, so LG Bridge thinks you need F600 firmware.
There is a v20L KDZ floating around here somewhere. Grab it, and put your phone in download mode (pull the battery / put the battery back in / hold volume up / plug USB cable in -- you don't have to hit the power button). Once you are in download mode, you can flash the KDZ with LG UP. That will get you to MM 6.0.1 which is still rootable using the dirtycow method (if you care about rooting). If you don't care about rooting, I am uploading the v30b Nougat KDZ right now. It is not rootable with any currently known methods. If you do want root, root on v20L, and then I will also be posting an update.zip that will take you to v30b and keep root.

My goodness, thanks for the prompt reply buddy, you saved my @SS im seriously not worried for root or bootloader unlock. im ok with stock nougat without root. so which kdz i need to flash ? im confused
As far as I know, no one has uploaded the Nougat KDZ yet, so I am in the process of uploading it. Google drive is being REAL slow. Since you don't care about root, you can use the same method that I described above (get into download mode, and use LG UP to flash the KDZ). I will make a post just a soon as it finishes uploading.
You might want to take this time to be SURE that you don't want root, because once you flash Nougat, there will more than likely never be a way to root this phone unless another exploit in the Linux kernel can be found...

No if you update h90130b your phone will be a hardbrick.
You have to upgrade F600S30d But you might lose the network !!!
@SandyKick If you can return that phone for an exchange, you might want to. As @dodo73 said, (in not so many words) you are boned. You are going to have to take a risk either way, but the safest route since adb sees the device as an F600, is to flash the F600 firmware. If you lose network, you can then try flashing the H901 modem. Let us know how it goes, but you are probably going to have to do SOME kind of fixup -- it will not be a clean flash / upgrade / happy phone
EDIT: If you flash the F600 firmware and brick your phone, that is also easy to fix -- and you will know that you DO need the H901 firmware.

I dont think going straight from 5.1.1 to nougat is a good idea. And after 1 hr of download if lg up is going to say incorrect kdz then why time waste
@SandyKick first we have to upgrade it to 6.0 to see everything goes welll then decide to upgrade it to 7.0
I have been searching for v20L kdz link but which model it is the huge problem
as we can not flash H901 kdz.
f600L?
F600s?
F600K?
There are three model with several updates. :/ Pretty confusing right.

Hi all,
I used the Frankenstein guide thread to root my phone successfully going from Nougat to Oreo, however it says the Android security patch level is May 1, 2018. I'd like to update it to whatever is the latest software version available.
It currently has US99820b_03_0524.kdz. I searched online and found US99820h_00_0318.kdz which seems to be the most up to date. Can I just use LGUP and choose Upgrade, and apply this? Will I have to re-setup everything again after it installs? I took a full backup using TWRP in case anything goes wrong, but I'm just looking for some guidance on how to do this properly. My phone is running fine, so maybe I shouldn't even bother, but I figured I'd try.
Thanks for any help!

The WTF INSTRUCTIONS answer this question. You didn't read to the end? Go back and read Section 9 of the WTF INSTRUCTIONS, please..
No, if your phone is rooted and you have TWRP custom recovery, you don't need to use LGUP to flash stock KDZ. Or else you will wipe out TWRP custom recovery.
Instead use TWRP flashable zips made from stock firmware KDZ. They are available in the KDZ threads, next to the KDZ. Go to the US998 Oreo KDZ thread and look for 20H TWRP-flashable zip.
You flash it like a ROM and reflash Magisk. There's other stuff you need to read also, but it's already written out.

Thanks @ChazzMatt for this as it was exactly what I was looking for. The WTF thread was so large I felt overwhelmed. I should have read it further. I'm now running 20H thanks to you.
I tried to root my phone but I failed among the many steps. I just flashed US998 ROM on my V300L because I ****ed up and flashed the wrong ROM instead of the stock ROM. And I didn't unlock my bootloader so I can't install TWRP. I tried to revert back to V300L ROM with LGUP but it's not connecting to my computer(I tried using another computer and a different cable.). And on download mode screen it says:
Unknown B78
Official / E / L / RO
It seems that the version I wrongly flashed was an Oreo Rom.
Update: Since then the device boots up to setup page but after a while it just reboots. It connects to my computer while in this state.
Please, help me get my phone back.

These were the directions you were following?
https://forum.xda-developers.com/showpost.php?p=76989743&postcount=7
Both H930 and US998 KDZ you were to flash are early Oreo KDZ. It's just you were supposed to flash the H930 first, unlock bootloader, then flash US998 to get modem working again. Also after bootloader is unlocked, V30 "trust chain" or whatever it's called is more permissive -- which is probably why you can't flash US998 first to unlock bootloader, but can after bootloader unlock on H930.
I notice those instructions (if that's what you were using) reference older versions of TWRP, root check disabler and encryption disabler. You need newer versions of those files, especially TWRP. You need 3.2.3.7. Newer versions of those files are found in the WTF Instructions. If you read that post, read in a web browser, not an app.
For your immediate problem, the only things I can suggest to you is to:
0) Try Master Reset to perhaps stop the bootlooping? May or may not work in this instance. But it's what we use after cross flashing North American variants. However, even then, we often have to go back to Nougat first.
With your device powered off, press and hold the Power button and Volume Down buttons simultaneously for a few seconds.
When the LG logo appears, quickly release and then re-hold the Power button while keep holding the Volume Down button.
Let go of the buttons when the onscreen menu appears.
When you see the option to Delete all user data (including LG and carrier apps) and reset all settings message prompt, press the Volume Down button to highlight Yes.
Then press the Power button to reset the device.
Wait until the reset is complete then reboot your device. If it’s able to boot up successfully, proceed with the initial setup.

1) manually go into Download mode before starting LGUP (power off completely, then hold volume up button while plugging in USB cable)
2) try both the newer Pie Dev Patched LGUP as well as the older "Oreo" Dev Patched LGUP. Pie LGUP does work on even Oreo and Nougat but there are certain situations -- and this may be one of them -- where the older Dev Patched LGUP is needed. Read the installation instructions carefully for both versions (they are different!) and uninstall any prior version each time you install another. Besides uninstalling, you may need to actually delete the LG Electronics/LGUP subfolder in the Windows Programs folder.

Again, IGNORE EVERYTHING else about that post except for the Dev Patched LGUP file and the installation instructions.
3) If you can't revert back to V300L, also try flashing to the Oreo H930 KDZ so you can finish the bootloader unlock.
Good luck. I don't have any other answers.

I was on Pie when I tried to root. I followed this instruction also by bilong9 https://forum.xda-developers.com/lg-v30/how-to/root-lg-v30v300slk-pie-t3957505
I did master reset. After doing that I got the phone to boot but after 3 or 4 seconds it would just reboot. It's just an endless cycle.
I booted into Download mode before connecting to LGUP. My computer doesn't connect to my device when in Download mode. I tried using different cables and computers none of them worked. Same results on everything.

I did master reset. After doing that I got the phone to boot but after 3 or 4 seconds it would just reboot. It's just an endless cycle.
I booted into Download mode before connecting to LGUP. My computer doesn't connect to my device when in Download mode. I tried using different cables and computers none of them worked. Same results on everything.

And you've tried BOTH versions of LGUP that I recommended? And you uninstalled and totally removed any prior versions before installing each TOTALLY DIFFERENT version?
Be sure to read the installation instructions carefully. They are totally different.

ChazzMatt, I have tried removing and installing both versions of the patched lgup and I'm at a loss. The DualMode zip doesn't read my phone and I notice it doesn't have the common folder when I run the dev batch file. The Oreo patched lgup goes into the set but it states the Dll =0. I am running a vs996 and trying to downgrade to 10d. I am at a 30c right now. Could you tell me a step by step of what you do to get the Dual mode zip patched lg up to work? The process I am filling is remove old, restart, install lg up, run admin on dev batch file, then restart and hook up in dl mode. Always tells me that it can't find my model.

Combining several posts in different threads and from PM into one question
These were the directions you were following?
https://forum.xda-developers.com/showpost.php?p=76989743&postcount=7
Both H930 and US998 KDZ you were to flash are early Oreo KDZ. It's just you were supposed to flash the H930 first, unlock bootloader, then flash US998 to get modem working again. Also after bootloader is unlocked, V30 "trust chain" or whatever it's called is more permissive -- which is probably why you can't flash US998 first to unlock bootloader, but can after bootloader unlock on H930.
I notice those instructions (if that's what you were using) reference older versions of TWRP, root check disabler and encryption disabler. You need newer versions of those files, especially TWRP. You need 3.2.3.7. Newer versions of those files are found in the WTF Instructions. If you read that post, read in a web browser, not an app.
For your immediate problem, the only things I can suggest to you is to:
0) Try Master Reset to perhaps stop the bootlooping? May or may not work in this instance. But it's what we use after cross flashing North American variants. However, even then, we often have to go back to Nougat first.
1) manually go into Download mode before starting LGUP (power off completely, then hold volume up button while plugging in USB cable)
2) try both the newer Pie Dev Patched LGUP as well as the older "Oreo" Dev Patched LGUP. Pie LGUP does work on even Oreo and Nougat but there are certain situations -- and this may be one of them -- where the older Dev Patched LGUP is needed. Read the installation instructions carefully for both versions (they are different!) and uninstall any prior version each time you install another. Besides uninstalling, you may need to actually delete the LG Electronics/LGUP subfolder in the Windows Programs folder.
Find the Pie Dev Patched LGUP here:
https://forum.xda-developers.com/showpost.php?p=79971595&postcount=3
IGNORE EVERYTHING else about that post except for the Dev Patched LGUP file and the installation instructions.
Find the Oreo Dev Patched LGUP here, bottom of post #1:
https://forum.xda-developers.com/lg-v30/development/us998-lg-v30-us998-us99820a040330-kdz-t3786337
Again, IGNORE EVERYTHING else about that post except for the Dev Patched LGUP file and the installation instructions.
3) If you can't revert back to V300L, also try flashing to the Oreo H930 KDZ so you can finish the bootloader unlock.
Good luck. I don't have any other answers.

Same boat. Flashed Pie over Oreo via zip, lost twrp, and download mode doesnt connect now...
I have problem with lg v30.
It is v30 VS996 (maybe). but it was flashed US998 Pie. And now it has an error on camera and fingerprint.
I can not enter download mode to flash stock rom and bootloader is locked.
Please, tell me what should i do.
Thank you very much.
See my response in the other thread where you posted.
And please don't cross post. It is very disrespectful of other members who are trying to help you. That's why it's against the rules on every forum on the internet.
