I’ve read that I can do a reset to factory with the jumper, however, after taking it apart I never saw a jumper anywhere on the device, save the reset button that is already accessible. I want to do the reset with the jumper. Can someone post a picture of where it is or tell me how to do this?
Model: Groove A-2Hn
Thank you!!
The groove has no jumper.
See the red circle.
Short-circuit the two halves by means of a screwdriver for reset the groove.

That’s what I needed thank you!!

You can do the same without opening the Groove. there is a reset button. it has the same functions as the circular jumper hole
