[Q] Totally bricked kindle after 1st attempt at adding TWRP. No power on at all. topic

I was following the steps on the lilputing dot com website (I cant provide links yet) to install TWRP so I could then install Cynogenmod.

These are the exact commands I entered, I got a "No space left on device" error at one point, something I noticed after I bricked the device. I'm sure this is the cause of the problem:

Code:

After the reboot statement the device shut down but never came back.

I fear I have killed the Kindle (my sons Kindle :(). It is not recognised at all via usb into the computer. There is no power light when I put on charge. Have tried holding down power button for over a minute but still nothing. Would I be right in thinking this is totally unrecoverable?
