While developing I have already bricked 3 Arduino Pro Micros. These devices were bought from china via ebay. It all happened by uploading while having a serial connection. So, the result was that the programming stopped in the middle. Now, they won't flash the green leds at all. The only led being on is the red one meaning power. How could I bring these devices back to life?
I have an arduino mega and an avr isp mk2.
