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

Hey all,
Not sure if this was the correct forum but seemed like a good starting place. Have 3 Verizon G6s and recently upgraded one to PIE and it SUCKS. Very slow. Some apps are not working. I want to go back to Oreo and never move to Pie until these phone die.
Previously I owned 5 different Samsung phones and rooted them all (some with stock ROMs, others with custom ones) so I have no qualms about tinkering but on this phone I use Google Pay so I need to find a way to revert back to a stock Oreo ROM, prevent it from future upgrades and keep Google Pay happy with what I did.
Anyone have a suggestion as to how to proceed or another forum to ask in?
Also, my other 2 phones keep nagging me to update and I would like to kill that request for good. Looking for help there too.
Thanks

How to disable system updates without Root
Give credits to these posts and their respective owners:
https://android.stackexchange.com/q/56620
The one listed below I highly recommend. It is what made this possible for me.
Check it out for more about getting set up with ADB.
https://www.xda-developers.com/disable-system-app-bloatware-android/
For other carriers besides Verizon, use apps such as App Inspector (I used ES File Explorer) and find the offending apps' package name(s).
You can also use Developer Assistant if the app you want to disable comes up in your face while using your device.
This app shows what the package name is of the app running in the foreground.
The same set of commands worked well for me, disabling the updates on (Verizon branded) LG V20, G6 and V30 all running Oreo.
The updates app or update notifications have not bugged once since I used the treatment (below).
If I open Settings and touch "System Updates" it gives no response.
Assuming you already have ADB set up and USB Debugging enabled and authorized between phone and PC, connect your device to PC.
The command line below works for any pre-G7 LG phones that are VZW branded.
I have copied cmd.exe into my folder where ADB.exe is located, that's the CMD you should open in the next step...or use your preferred method of running ADB.
Run these 4 commands in CMD:
Code:
adb -d shell pm clear com.lge.lgdmwebviewer4vzw
adb -d shell pm clear com.lge.lgdmsclient
adb -d shell pm disable-user --user 0 com.lge.lgdmsclient
adb -d shell pm disable-user --user 0 com.lge.lgdmwebviewer4vzw
**THAT'S ALL IT TAKES***
If you saw "Success" after each of the above commands, you just won the lottery!
Disconnect your phone and enjoy no more pesky "update available" popups!
I haven't tried this yet, but if you want to downgrade, check this thread from the G7 forums: https://forum.xda-developers.com/lg-g7-thinq/how-to/cross-flash-oreo-pie-firmwares-lg-g7-g7-t3915303
It obviously works on G7 so maybe it will on G6.
Please post results if any one reading this has done it.
The latest VS988 Oreo firmware can be located here.

I would recommend using this LGUP 1.14 patched, kudos to mylgphones.com for posting them.
Direct download link is https:// drive.google.com/open?id=1SOhoR2hn9PKiIvUUeiDVeX-8PfuMx1qq
Remove space in the link, XDA doesn't let me insert links
After you run the MSI install file, copy the files from the patch folder and replace the originals in "C:\Program Files (x86)\LG Electronics\LGUP" or wherever you installed LGUP; make sure you replace the DLL file with the patched one as well.
I killed my updates when I was still at version VS98820e so I don't have any experience with downgrading from Pie myself.
I would suggest to make sure you have the LG mobile drivers installed first; and when you go to flash the KDZ, make sure you backup all your userdata first.
Then shut off your phone, hold VOLUME_UP key and connect to PC. You should see download mode appear within 5 seconds.
Now, on your PC, open LGUP and it should open to the connected device selection menu. Choose your phone and press OK. The next window should be the main LGUP window. I haven't tried it but I would suggest to use the "Update" option then load your kdz file in the "bin file" area and flash. If it doesn't flash successfully, use the "Refurbish" option instead.
Hopefully this helps someone to recover from the Pie dilemma! :laugh:

Yes. Successfully downgraded.
Used a couple of files from the g7 forum for LGup and a dll file, it's very easy.

OK here goes
1. Download the latest Oreo from lg-firmware...
2. Download LGup version 1.14 along with a .dll file from the g7 forum. You'll need to put that. Dll file inside a folder when you install LGup for it to prevent any errors and allow downgrade
3. Install all drivers properly
4. Put the phone in download mode
5. Select the kdz you downloaded from the firmware site
6. Hit start...
Wait for it to end and say 'successful.
7. After you set up the phone, factory reset it once then set it up to prevent battery drains and smoother performance.

I did as your instruction, however, at step 6. , it ran 4% and then stop, an error board appeared with ".dll" error (I don't remember exactly the statement, but in short It requested me to use appropriate dll file). I did try several dll file but couldn't find the one that allow me to pass 4% installation loading

sorry for the late reply, but as i mentioned, you will get the right .dll file for lgup 1.14 from the g7 forum linked in the earlier posts. replace it with the one you think isn't working. i faced the same issue and solved it
Okay, so I'm trying to flash the US998 20b KDZ but I am unable to get into bootloader/download mode.
Typing 'adb reboot bootloader' just reboots the phone like normal.
When I manually enter the bootloader via the volume down and power button trick, it's not recognized by the computer.
On the screen are 5 options
Continue Power up
Safe mode
Factory data reset
Wipe cache
Power down
Yes folks, it's the recovery partition, not the bootloader.
Running VS99630c.. Any ideas?

Try different computer, make sure you have LG Mobile drivers installed, etc.
There's a list of Trouble Shooting Tips for installing Dev Patched LGUP.
Your not going to be able to use fastboot or ADB on Verizon firmware. That's the whole reason you have to temporarily convert to US998.

i downloaded the LGUP DualMode v1.14.0.3 zip. I followed the readme to a T and it did not create any desktop shortcuts or start menu entries.

Maybe I downloaded the wrong zip file.

I did that, but whatever I do, I still get the "Not support cross model download" error.
Never was an icon created on my desktop for LGUP.
Then again, when I plug in my phone when in download mode an exclamation is displayed over a "CDC Serial" device.
But it seems like that is unrelated, seeing as how when one selects "Partition DL" it changes to "USB Connection Established." when the select partition dialog is open. Of course I clicked cancel.
Any hints?

While you need to eventually get to US998 20a or 20b, we recommend flashing to
* USS98 Nougat first,
* doing a Master Reset (to stop bootlooping),
* then going to early US998 Oreo 20a or 20b.
Via Partition DL.
See Frankenstein instructions. Frankenstein is how all the North American variants -- EXCEPT T-mobile H932 -- convert to US998.
It's mentioned in the WTF instructions also, but some people have overlooked it.
The Frankenstein instructions have same version of Dev Patched LGUP attached, as well as separate download link from the dev.
Something is not being installed correctly. Maybe use another computer.

Finally got US99820b on the phone. Now for bootloader unlock, twrp, and vs99630c zip
Edit: fastboot drivers installed, works like a charm
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?

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 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.

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.

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:

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.

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
