How to perform "factory reset"

Hi there,

I owned a Beaglebone Green Wireless. I have some troubles to connect the beagle to my wifi. I tried so many thing without success. However, my settings seems to be broken. Now I try to reset the beagle completly. I flashed the latest image file on the beagle (on eMMC) but the user settings are still the same. How do I come to “clean” beagle?

Kind regards

Did you ever find the answer?
