Apple TV attempted jailbroken aTV not working

i have apple tv2. After going through the process described with season pass, everything worked as described, entered DFU mode and the auto restore started. Then I had power failure. Now when I connect the aTV to my TV it shows, the iTunes logo and a USB cable, I try to reset with the remote but still the same. If I connect with the USB to my computer it does not appear in iTunes. Trying to re-enter DFU mode, but nothing.

Please advice

Thanks

it was actually all about the micro usb cable, bad quality. problem solved. thanks
