Same here but there is a three-button option in gestures so I use that until I have figure out of buttonless is the way to go. The problem with the soft buttons is that you don't have the various long short press settings.You definitely got the hookup even though I prefer the hardware buttons of the OP5. Congratulations!
But hey OP5T can't complain. Also deleted all OP5 specific stuff from the PC so I don't go and flash something I should not notice my Data Partition I went with your setup.
