Hey Ryan,
Vince answered my mail and gave me the following advice:
It sounds like you will need to do a hardware reset. To do that, open up the pedal, and then on the back of the PCB, you will see two angled contact points that need to be shorted (connected with a paperclip or something similar) while the USB cable is connected. That should then flash the DataLooper back to an initial firmware. You can then try reflashing the firmware onto the pedal. Make sure you’re directly connected to the computer when updating the firmware. Things should still work with rev-1.
on my PCB the string „PGM1“ indicates these contact points. So i did it this morning and it worked. 🙂
i assume it will work with your pedal also since it’s just a software problem.
best of luck.
