Bricked N2560 need Help with serial conection

[ibanez]

Hi,

 

I do not know if it's a coincidence or conspiracy, but I was the victim of a power failure during the flash of the 6.1 OS via an USB key,

 

My N2560 is bricked now (No booting, it does not recognize USB keys, no bliking light, all the lights stay ON, reset and ON buttons not working after powring on the NAS)

 

I bought a cable like this one :

 

 

and i need help to flash it via the COM-port.

 

this is the only information i found on the internet :

But i dont know the command lines to use with putty and how to send the flash files via the COM-port, in addition i really dont know which file i have to send to the NAS.

 

 

Thank you in advance,
