thank you guys for answering!

it works with external power jack , USB and even via VIN pin, but i just can't load any sketches in to it.
no worries i buy a new one it's only 54€. shitty thing is that now is sunday and all shops are closed smiley it's not worth to start changing some parts by soldering.

lesson learned do not prototype nothing middle of night. i build stepperMotor control with darlingtonArray on my breadbord and accidently i got mixed with wires so motor side power 12V got in control side 5V.

hi tomKi

it's the latest mega 2560, do you think that it could be fixed somehow.

hi!

i accidently set 12v on arduino mega 5v output pin. board still works and runs my program, but i'am not able to load any new sketches to it. TX / RX lights dont response and arduino IDE says timedout() etc.. when try to load new sketch in it.

i think there's nothing else to do that buy new one?
