  • I was able to reprogram using a TinyISP. The trick, suggested by my 9 year old, son was to flip the 6 pin connector on the ISP so that you reverse the output pinout. We burned a bootloader and then blink uploaded no problem. The suggestion from above to press a header into the pins worked great! You have to have the Twinkle powered up and not have the 5V jumper in place.
