Question "flash failure"

Guys, i need a little help.

My phone just got dead. And i don't know what i need to do...

When i try the "AP Fastboot", i receive the message :

"Fastboot Reason : Flash Failure
fastboot : max download size : 100mb
USB connected"

So, when i try to flash with RSD, the phone show's this message :

"Getvar max-download-size
Downloading...
not found partition cdt.bin
E: No partition cdt.bin existing
Fastboot command failed."

__

I don't know what to do. And i didn't try to unlock or something like this. This is my father's phone, he was playing and, in a second, the phone go off and never wake up again.

Can anyone help-me plase?


Thanks!
