How go I downgrade from a v20 rom to v10 I tried to flash with KDZ_FW_UPD but its crashes
It seems that currently there is only one way to do it, using a KDZ from 4pda. Check the solution from development section http://forum.xda-developers.com/showpost.php?p=39606536&postcount=333

hello. i searched and couldnt find a way to use KDZ or TOT softwares or where to find them.
i want to downgrade my LG G2 D802 from 4.4.2 to 4.2.2.
PLEASE HELP!!
@Delphinus3 please see the general thread going back to stock tot thread
Are there any working custom recovery modes/root for the phone and software version number in the title?
No. Downgrade using a kdz then you can.
Do you have any links to downgrade using KDZ and to the root/custom recovery process? I cant seem to find them.
Do you try kdz 13A?

To downgrade google vs995 firmware and grab the vs99512a that's the firmware that came with the phone new. Also grab lgup that's what you need to push the firmware on the phone.
Kdz link
lg-firmwares.com/download-file/?fileId=4889
LGUP DLL is needed link below

so i have a att (H910) Lg V20 and i was trying to flash a new rom because my old one keep crashing randomly(Mega rom) so i tried to flash the lineage rom but when i use twrp to try and flash it , it tells me that i have a H918 for some reason and i can't flash the rom, do i have the wrong firmware or something? help guys
I have a question I was thinking of using the h915 kdz on my AT&T LG v20 variant. I saw the post about using patched lgup with common dll. I tried this method without success. Lgup kept saying that I it cannot flash h915 to h910. I cannot seem to get around this. My query is can I use another carrier kdz on my phone and which one should I use? And an someone assist with the process? By the way I am using LG V20 H810 currently on nougat. Stock firmware don't want to lose root, just want Android Oreo. Thanks in advance. Also is there an easier way to gain root besides dirty Santa. Seems so lo d and risky.

Use pathed LGUP file in thread:
[GUIDE][UNBRICK] Patch LGUP to unlock features & unbrick V20 (Variant mismatch fix)
and you will can to flash h915 kdz, or us996 kdz. Don't flash other kdz, you will loose your phone.
only one method to access root -- dirty santa.
You can just run follow the instructions in the root thread https://forum.xda-developers.com/v20/how-to/root-h910-v10m-t3664500 on any version H910. Backup anything you need, including from the internal storage and SD card, before you start.
Follow the instructions exactly as written,until they tell you to flash the h910-10r ZIP. Go here, https://forum.xda-developers.com/v20/development/h910-att-lg-v20-stock-oreo-rooted-t3846384 get the proper version of TWRP, download the v20h ZIP, download the proper mk2000 kernel, and the Magisk 17.1 ZIP,then flash the rooted v20h ZIP.

I have received oreo opdate via ota 1.2gb but it's failing getting error during installation..
I bought a used v20 and i think its running modified rom nougat 7.0 .
It has all languages and unlocked hotspot tether and bluetooth tethering .
Thats why it's getting error via update because it has been modified.
I
If i flash your stock rom will i get ota update or no

Yes my 20g stock rom will update to 20h no problem.
If you want root those roms are their also
Be sure and flash TWRP again before you reboot if you need it all my roms overwrite TWRP with stock recovery

Thank you for your support
Please i want to clarify something .
I am reading many posts in xda and reddit that some users successfully converted from H910 to H915 or unlocked VS995 or VS996 i am not sure which 1 is fully compatible with H910.
I just want to know can i flash stock kdz H915 or whatever to my H910 directly from LGUP or i have to root and flash via twrp?
Also I've been reading that flashing via official LGUP won't work because model difference so i have to use LGUP PATCHED VERSION.
TIA

The H910 - H915 and US996 are essentially all the same device
The H910 cannot be unlocked with the stock bootloader
The H915 will allow you to flash a Engineering bootloader that is unlocked
The US996 can be unlocked through LG
I really don't recommend cross flashing except to install the unlocked bootloader
this is done with Patched LGUP
all the instructions are in the root thread I posted above
