Some have successfully downgraded to 5.1 from 6.0 with F600 at LGviet forum. So please say thanks for what he built for us instead of saying this, you can hurt the owner!

I encountered the same problem with my LG F600L when I was trying up upgrade from MM to Nougat. But before you start did you check the Anti-rollback version first if you are in V0 then you should be good to go. What I did to revive my phone was I use Uppercut. To do this, look and download for Uppercut get it here Uppercut. Once you have downloaded Uppercut close LGUP. Just pull the battery of your phone and re-insert it will boot to download mode automatically, plug it in now DO NOT launch LGUP click Uppercut as this will call LGUP to open automatically then select refurbish and select your KDZ then click start. Tell if this works for you. By the way, make sure to turn off your antivirus as this will detect Uppercut as false positive and it will not run.

What can i do to get my lg g3 working again?

:crying:
My issue is quite complicated. Please be patient and read on.
Less than a week ago, I bought an LG G3 D855. It wasn't brand new and definitely out of warranty.
It was on the 4.4.2 Os version but I couldn't update it because I couldn't locate the UPDATE CENTER and after some research online, I found out it was because it was rooted. I couldn't find a Supersu application anywhere on the phone anyways but Root checker confirmed that it was rooted.
I downloaded the stock kitkat firmware in a .tot format and I tried flashing using LG Flash Tool for TOT but it failed because "Device version is different"
I checked the Imei online and it stated that the device is a Sprint LS990 but the details embedded in the phone all say it is D855
I checked online and found a couple of posts about this error and one user said he was able to fix it by flashing the actual Sprint .tot with the lg flash tool. I tried that but it didn't work. It still said "Device version is different. Check BIN or dll"
I checked online and found results pointing to a generic .dll file for G3s and I downloaded it but when I used it on the Flash tool, it resulted to an error "CrossDL blah blah"
So I found a Marshmallow kdz file. LGUP won't see my device model so I was able to flash it after editting the software in my build.prop to D85510n.
***I have always changed the port to COM41 in all the steps I used
The LG UP detected my model and it flashed to 100% but got stuck on a bootloop by loading the lg screen, freezing and restarting by it self. It never gets to the homescreen.
I downloaded lollipop kdz reflashed using LGUP in a form of downgrade and it got to 100% and got stuck at the lg screen while trying to reboot.
I redownloaded the stock kitkat rom and used the Lg flash tool but it failed. It said 'PID null IMEI Null"
I used LGUP to reflashed. It came to my understanding that the LGUP can flash both kdz and tot. So it flashed to 100% but got stuck at the lg screen and I have tried all I can but it is stuck. It can go into download tho. I don't know what to do about the IMEI. I don't know if the last flash retrieved it. I don't kniw what to do.
It no longer shows as LGE AndroidNet USB Serial
Please can anyone help me?
I just need my phone to work again. I was stubborn and now I regret it. I should have just stuck to kitkat. I'm so desperate to get my phone working that I wouldn't mind Android Froyo Os if it was ever possible.
PLEASE HELP!!!

I also had some what same problem with my old lg device ... Here's what you can do:-
Download any custom rom of your lg g3 Like Cyanogenmod and flash it via recovery.
Recovery can be stock or custom it doesn't matter.
Remember to wipe dalvik cache and wipe data before flashing the ROM. I did it and my device was working fine.
Remember that first boot
always takes 2-3 mins so be patient.

Restore v20 to 100% Stock (!!even for bricked devices!!)

This is a simple method to restore your v20 to stock, I have tried with my bricked H990DS with wrong bootloader flashed.
1. Download .kdz file for your v20 model from the following links. Currently v20 models available are:
F800K, F800L, F800S, H915, H918TN, H990, VS995, H990N and H990DS
H990DS https://lg-firmwares.com/lg-h990ds-firmwares/firmwares/
H990N https://lg-firmwares.com/lg-h990n-firmwares/firmwares/
https://lg-firmwares.com/
2. Search, download and install LGUP ( LGUP_Store_Frame_Ver_1_14_3.msi ) and a file called LGUP_common.dll
2a. Copy the LGUP_common.dll to C:\Program Files (x86)\LG Electronics\LGUP\model\common (May need to modify folder access right)
3. Search, download and install LG Driver ( LGMobileDriver_WHQL_Ver_4.1.1.exe )
4. Completely Power off the v20 ( or to remove and put the battery back )
5. Plug the USB end of sync cable to your PC
6. Press and hold "Volume Up"
7. Plug in the USB-C end of sync cable to the v20. The phone will enter download mode (or Firmware Update). Now you can release the "Volume Up".
8. Run LGUP. The program will regconise the v20.
9. At the file path, click "..." and chose the .kdz file
10.Choose "UPGRADE"
11.Click "Start" and wait until the process is complete.
Now we have a safe method of restoring bricked v20. Hope developers can start trying to root without worrying of bricking the phone.
This method is verified on my H990DS. If anybody successfully flash using this method please let us know. Thanks!

Great thread! Just want to add a quick PSA for this:
This may update your phone to the latest firmware which may patchs the current recowvery exploit. While this will unbrick your phone, you should make sure that you have the a firmware below 10i (w/o patch) to flash. If you still have access to TWRP and don't have a 10d firmware for your device, use this instead.

While this will unbrick your phone, it should be used a last resort for those still using the 10d firmware and have access to TWRP (use this instead).

Thanks for the reminder. Actually it depends on what .kdz is available. For H990DS there is actually v10b firmware for download. So after I flash using this method the dirtycow exploit is still there. Take a look at the filename of the .kdz (e.g. 990ds10b_00_OPEN_TW_DS_OP_1125.kdz is v10b released at Nov 25) Seems that versions below v10i are still ok for dirtycow.

Ahh! Nice! Hadn't considered that. I'll update my OP

Darn. Got my hopes up. No VS995 in the list. No T-Mobile and no Sprint either. I don't need it....yet...but I would love to have a restore method for my VS995. Though I've had an LG G3 rooted and flashing custom roms, kernels, and mods for 30 months and never once restored it to stock so perhaps the V20 will be the same

are you using uppercut for the model .dll in LGUP?
i have tried this method a few times over the last week, no luck. but i was pretty rough with my phone to be honest, no backup and tried all the other v20 variant roms.
right now LGUP detects my phone as a US99610D so will not flash the H990DS firmware, tried to edit the kdz in hex editor for name value but it detects the kdz as corrupt now. any experience with this?

so you found a v20 dll file? do you mind posting a link? or how did you get past LGUP picking up v20 as unknown device? or was this not an issue for you?

The LGUP first did not detect the device and asked for driver. So I installed the driver as mentioned in OP. After that i was able to flash the phone with the kdz file.

What do you mean?
If this method worked for you & a few other users, it should probably become a sticky rather than closing the thread...
Unbricking a device & restoring to 100% stock is an important feature to most, so if a few users are having issues we should probably help sort out those issues rather than abandoning the thread...

don't close it off, if it worked for you it should work for others that haven't broken the phone quite as much as me (boot, recovery, aboot and system changed).
the dll looks to be a requirement, perhaps uppercut worked for you prior to you AV killing it. i used it despite the AV alert.
so that part works fine, my phone is detected as version US99610d (files used during root attempt) which prevents me running the KDZ with "Error: KDZ file is invalid. US996 -> H990"
i tried to edit KDZ file to change version from H990 to US996 but this just corrupted the file.
i edited the model in build.prop of a rom and flashed it but it failed to make a difference to LGUP.
in a last ditch effort i restored aboot.img but phone is still detected as 996 instead of 990. but now no more twrp or unlocked bootloader.
any idea what LGUP reads the version info from or how to force it to run a KDZ from a different model?

Only issue with that is I think the device would need to be rooted.. which it's not rootable. Which would explain most likely why there's not one already uploaded for the tons of users who attempted to downgrade.

Sadly it'll be very unlikely that root will be coming anytime soon for the H810 if at all at this moment.

Secure booting error after sd card unbrick method
I bought used h811, but it has issue of restarting every time I tired to uninstall any app or tried to go to security setting. So I decided to downgrade it (I have no idea about ARB at that time), the device show h811-21y, So I download h811-10n firmware & use lgup to downgrade after it complete 100% it get bricked, and show qualcomm 9008 on the PC. I then open the device and found out it is h810 written on the motherboard.
I tried almost every qfil mbn files present on the internet but failed.
Then I tired this firmware
LGH810AT-01-V21y-310-410-JUN-20-2016-ARB03+0.rar
and use this youtube method to create raw programme & patch
watch?v=RhG02kmSelk
Then I use sd card method as this youtube method suggest
watch?v=kX2Fm1zEx5E
my device show sign of life but stuck in "secure booting error 1009"
At that point I am totally stuck since I does not get any help with this error on the internet
