I have now succeeded in bricking my beloved PRS-505. I was using PRSCustomizer to update my firmware from 1.1 to 1.2 and it stopped during the process. It now displays:
Firmware update did not complete successfully. Please try again
It does not respond to a hardware reset. It is not recognised by my PC via USB and subsequently cannot be updated with the Sony tool.
Help is much appreciated.

Solved the problem. It seems that the hard reset button on the back of the PRS-505 needs to be pressed
very firmly and
more than ten times
Gosh, that was a very scary few hours without my reader!
