Hi! I have tested Loop back test and my board echoing back (NANO v3.0). I can't still program nano board. I am thinking that MCU ATMega328 is broken??

I would call that a pass. FTDIs rarely go out.
So when you plug it in to USB, does it blink 6 or 7 times on the LED?
When you upload, do both Tx and Rx blink or just Tx or none at all?
Do you have another Arduino or programmer that can get onto the ICSP header?

Could be, but maybe the auto-reset function is not working correctly. Have you tried using the manual reset when performing the upload command. Press and hold reset down, press upload, and when you see the compiled sketch size displayed on the IDE, release the reset button.
