Re: [jornada] Bricked Jornada 568

One of those articles is very interesting. If you hold down the 2 right
hand buttons on your Jornada whilst powering it up, you get a bootloader
  menu which should allow you to recover your jornada by various means -
the most interesting one for me is from Compact Flash. The only problem
is, the only copy I have of the system is the backup I made from
Bootblaster and it doesn't seem to recognise this...

Anyone have, or have any idea where to get this system file (apparently
needs to be called nkrom.bin). Even if it's not english, it doesn't
matter massively...

Hope someone can help so I don't have to resort to jtag..

Cheers

David
