Downgrade LG Aristo 2 from Oreo to Nougat with LGUP issue - Android Q&A, Help & Troubleshooting

Because of an app incompatibility issue, I need a workaround for LG Aristo 2 downgrading from Oreo to Nougat.
I read a tutorial from techknight about the downgrade process using LGUP. So I grabbed a few .KDZ files from LG-firmwares.com. I get into LGUP fine using uppercut and try to install one of the .KDZ files.
It gets to 4% and gives me an error message. Please install latest DLL LAF protocol version is not match DLL.
It shows DLL=1394615440
Device=179114016
I just do not know what to do to fix this and get my Aristo 2 back to Nougat. There is no data on it I am worried about keeping.
I appreciate any advice that will help solve this and thank you for your time in advance.

I'm in the same boat. No idea how to fix it up to now.

Be sure to give the file admin privileges. That is the part I missed.

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.

extract kdz to dz, and try to flash again using dz file
Try to use Uppercut thats what I have used when I bricked my phone flashing the Nougat update and it went to endless download mode (semi bricked). So I flash the F600L20e_00_0216 KDZ to restore back to MM and it work!

The one I downloaded was from the G5 forum it has version 1.0.0.0 Uppercut as this one supports the chipset V10 has which is MSM8992. Then I also used it to update to Nougat from MM. In my experience, I tried to update from F600L20s MM to F600L30e Nougat at first I tried to flash it using LG Flashtool 2014 using the KDZ unfortunately it looks like it is not supported probably of the new chipset it always gives me an error "Contact the system administrator error" when it tried to extract the firmware. Since I don't have the TOT and DLL to try the LG Flashtool ver 1.8 which uses the TOT so I used LGUP.
I connected my phone to my PC normally, enable debuging mode and run LGUP, then it automatically put my phone in download mode and started to flash. Almost half way of the flashing it gave me an error "Error code 0x2000 invalid command response". So when I rebooted my phone it just bootloop to download mode no way to boot it normally. What ever I do it just got to download mode so f*cked up my phone then I remember that others are using Uppercut, so I downloaded the version that supports the V10 chipset. So I installed Uppercut disable my anitvirus, reboot my phone (even though its already on download mode) I downloaded F600L20e_00_0216 to rebuild again my phone back to MM so I open Uppercut and it automatically opens LGUP then select the MM KDZ then click Start crossing my fingers it shows successful and behold my phone is back and up running again. Since I wanted to update to Nougat the same method I used flashing the MM firmware and same result success.
i downgraded my f600l from f600l30e to f600l20e you need to disassemble your phone > short two test point pins to force phone into qualcomm 9008 mode then use qfil tool to flash files extracted from f600l20e .dz
its not too easy but if you have a skills you can try
now im trying downgrade to LP to get root

If you dont need to do this. You can flash wrong kdz to brick the phone into qualcomm 9008 mode then use qfil to flash required files from f600l 20e .dz
Then you can flash f600l20e using lgup .
But make sure your phone's motherboard is f600l

LG G5 IOT_H850_Marketing upgrading to oreo! Please help!

Hi guys, i recently bought an used LG G5, after checking out the IMEI with an LG representative via email, it turns out i have the marketing version. I tried upgrading to 8.0 on my own using the regular software update on the phone with no success. I tried using LG Bridge, where it says that "your phone is up to date" however after i press ok for that message, it says that there is an update available "H85010DX". After i click to continue to get to the downloading phase i get the error message "The update cannot be downloaded because there was a problem with the server"
Knowing all of this, is there a way, no matter what for me to upgrade to Oreo? Thanks for ur time guys!
Try with officila KDZ upgrade for H850, using Uppercut and LGUP.
You can find the firmware here and LGUP and Uppercut (with instructions) here.

I am trying right now! Coming with a reply!
Nice! Before trying to flash the KDZ, have you tried to unlock the bootloader with the official LG method? That would allow and easier and safer upgrade via TWRP.

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
