1. did you download this kdz?(it's modified so don't try other 20P's)
2. if you still keep getting 0x2000, then try to extract nougat(29a) kdz's dll, rename and move to the proper folder

Tell also that I've to use upgrade option or use refurbish option with h818v20p_00_0314.kdz

select refurbish option for that and you're good to go

hope it helps

keep calm bro
no dude, it's not going to install nougat on your phone. actually it just gets LGUP to recognize your current OS(v29a).
1. run WindowsLGFirmwareExtract.exe
2. add the nougat .kdz file and select LGUP8974.dll and click extract kdz(Rename LGUP8994.dll --> LGUP_8994.dll)
2.- Move the extracted DLL to the LGUP directory and replace the old DLL (Example: C:\Program files\LG Electronics\LGUP\model\8994)

3.- Now flash the kdz v20p, then you'll be able to flash any other KDZ.

try it and you're welcome

Right click on LGUP_8994.dll and go Properties click on Detail Tab and look for Productversion, it must be 0.04.0

fren...
this is the dll you need: https://drive.google.com/file/d/1KRcuslcxmcNTLgzjbMkCJzX1d-VMt8Vr/view?usp=sharing
so you don't need to extract it anymore.
just move it to C:\Program Files\LG Electronics\LGUP\model\8994 and tgen flash 20p kdz using lgup
