Can anyone help me from upgrading failed ?

[slawdan]

My friend gave his old cybook gen3 (64M) to me and , tried to upgrade to fw 2.0. And he made a mistake for delete something in the fonts or system directory , after completed the normal upgrading actions and rebooted, the device shows black/gray/white blocks still.I've tried to down and install some home-made fw also, and failed time and time again.

Can any one send me a filelist or zipped fonts dir, or do me a favor of giving some advice to repair it?

Thanks a lot.
