Hi,
I was also trying the reset pin with no success on a Netduino Mini. I have 4.2.0.1 firmware and I want to downgrade to 4.2.0.0 to see if I can get that to work, the problem is the link for 4.2.0.0 on the official wiki is dead and I can't find it anywhere else. Could you please repost a link for the 4.2.0.0 firmware for the Netduino Mini?
Thank you.
