I know this has been done many times, but:
On the third day of a 18 day motorcycle trip, my karma stopped playing as it has been doing occasionally. I used a paperclip to shut it off (as it wasn't responding) and stowed it away for a while. Ever since it hasn't booted up though. It starts booting, shows the splash, and when it should start the progress bar it shuts off. I put it in recovery mode and it shows unhappy karma and:
rom v0.26
hwrev 00000004
hdd: hitachi_dk14fa-20

After plugging in the USB and attempting to load firmware v1.68, I get 'Error 0xc004a006'
Any suggestions?
