You dont have to read the atmega just erase it then rewrite new file to it
you dint need to remove the chip

put chip back in xprog
connect other xprog to broken xprog as been told and then erase and reprogram with 5.5.5 dumps
if you have other xprog already then you dont need to go buy a third

yes . i not remove the chip. i pinout all aready solder but i only has 5.5.0 xprog now cannot read or delate...now i just waiting new xprog 5.60 with dongle... after i get my new xprog i just can repair atmege.. thank mate ur information is important for me..
