marokino08 thanks for your answer. With loader Upgrade 2.0.0b i don't have the option ALL CHUNK, i have UPGRADE and DATA DUMP.
I tried with both UPGRADE and DATA DUMP and i got this "Open Serial Port..Sync to serial port..Target not connect or target is error status!".
At the same time on starsat screen i got "ASH".
I'm i doing something wrong?
