Scott and Gonk,

Thanks for your advice messages. I've tried them both - with no success. The upgrade loader still freezes at either the erasing or the data setting step. This time it's data setting - been stuck there for over 15 minutes now. On both attempts today there were "device restart" messages. I have followed Scott's instructions (sent earlier today) exactly both times, and this last time I also cycled the Master Power switch several times, per Gonk's private message to me. To no avail.

I sure wish I could say "Thanks and congratulations - your idea worked!"
