My Zen is Dead apart from the Blue light being on

[PMCRO1]

My 8Gb Zen had been working perfectly well until last week. I was charging it on PC and it was charging a normal. When I disconnected it I could not get it to switdh on. Plugged it back into the computer and it was only recognised intermittently. I successfully upgraded my Firmware as advised. Following instructions from various thread . I got into Recovery mode, I Cleaned , then Formatted and then removed the firmware. Got connected and tried to apply firmware upgrade but this was unsucessful. When I rebooted then I got a white screen and the blue light on the on/off. Reset the machine. No longer recognised by computer when connected to Computer and Now when trying to get into recovery mode it goes to Creative screen then goes to a black screen and the blue light is permanently on. Is my little friend dead and beyond redemption.
