I followed the directions found here:
http://www.owen.org/zaurus/nand.phpand get nothing more than a flashing yellow battery light. No "service menu" as I've read about. I've read that the service menu can be wiped out. Is it possible that's what happened to mine? (I got my machine off of ebay)
I'm trying to find a good reliable way to back-up my system as well as my data, and am not having much luck.
Suggestions anyone?
