downgrading LG65uj634v 2017

[necrofobic]

ok so im slowly going insane, just got a new tv and naturally i couldnt keep my fingers off the "update" button.

before the update the HDR game mode was crisp and bright, after the update it so bloody dim some games are just... way too dark ?

 

so i tried running a downgrade with lgdtvupdater and got everything to work but when its time to actually download the update to the tv it says that "the update cannot be applied".  everything in the logs are showing ok. but it just wont save to the tv.  it doesnt even start the download, altho i can clearly see in the logs the update is correct and the tv has given the "all clear" to the update server.

 

am i missing something here ?

2017 models seem to have an extra check against downgrading. Sadly, nobody has found out a way to downgrade firmware on those models yet.
