azrider,
You just pushed the wrong sequence on those buttons. I have never gotten mine stuck in Reverse, and I'm not going to follow these just to see if I can
But here are the instructions I have, they came with a replacement motor I got from Cobra Steve and are in the original Chinglish
I'll use V for the down arrow graphic and ^ for the up arrow graphic
"""
o THE NORMAL REVERSE TRANSITION SETUP FOR THE MOTOR
Motor manufactured set is the reverse transition. If you need to reset: when the motor stops, press the V button for several seconds. when LED is "SET.0", press ^ button with 2 times; when LED is "SET.2", then press the V button again, LED is "roT.E" or "roT.P". If you want to change the transition, and you could press the ^ button for the switch of the transition. 5 seconds later the set pattern will be automatically saved;
"""
This is exactly what it says. Don't ask me what e.g. "button with 2 times" means
Hopefully it will make more sense when you start punching buttons and watching the LEDs.
