Need Help GTR bord and remote paired but not working

Hey I've had my GTR new for a few years. Never had a problem. Recently tried to do a firmware update from the evolve app The board and the remote would not connect. The board would connect but wouldn't allow me to actually press the update button. It seemed not to make any changes. I Also was a messing around with some other settings just normal stuff like adjusting trigger values and things like that. Now for some reason since then the remote will connect to the board but the power and brake don't do anything. Any help would be greatly appreciated.

 

Recalibrate the remote it's opposite of what it says on the screen check evolves procedure on you tube
