I have an LG v50 and I just successfully did the process using LGUp, in my case LG Up was older and needed to update to vers .16 or higher  [came up as an error] but once upgraded 'downgrade' went thru

I quite like Android 9 ..so far

hi there !! what was your procedure to downgrade just simply reflash the old one ?!
