LGUP error

[NevErSn0w]

okay guys, so, problem
trying to downgrade my LG G4 H815T thats currently running 6.0 to 5.1 due to crap battery life.
now, heres the problem
when i attempt to use LGUP as said in the forums, it comes up with this error: DLL for H81520D is not installed properly. Please, install a DLL package (*.msi). for the model.
i've looked everywhere for a fix, uninstalling and then reinstalling, tried installing the DLL first, then the LGUP software, etc. and no luck, tried 5 different computers running between windows 7 and 10, still no luck. anyone got any ideas

Cheers

Are you using the LGUP from here? http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803

Also, do you have all of the drivers for the phone installed?

install the DLL BEFORE installing lgup

uninstall lgup
reboot for good measure
