I was using studio 3.65 and an AVRISP device to programme my Mega8. I upgraded to studio 4.10 and when I tried to prgramme, a pop up showed that the firmware is older and needed to be upgraded. I clicked yes and after some time the system stopped. Soon after this the avrisp stopped working. The green and red leds also stopped glowing and studio reports that it is not able to detect the device!! I am presuming that the firmware got disturbed. Is ther any way I can reprogramme this device?
