So after some accident I touched GND to 5V, and now it seems to do this. I can still pickup Serial.write('stuff') on computer Terminal, but no way does arduino respond to serial.read (or, whatever I send from PC). I can't see Rx LED turning on neither... what to do :S?

Pass or fail?
Interesting, it passed. This means atmega8u2 chip (aka serial chip) is working... But, AVR also does respond to programing. What the heck?
What the fu*c, it works normaly now. Also, the older board also works for which I thought it was gonner. ]
