Hi,

I think it depends on the zaurus you have.

On an 860 press FN+D+M at the same time without battery and without power connected. While pressing these three buttons plug in power to enter the diagnostic menu. There you can do a NAND-restore.

If this is not clear enough or you don't know how to do NAND-restore, feel free to ask.

Cheers, Jan

Thanks for answer.Can you explaine me How I can restore the original nand(With the sequence you tell me Zaurus enter in restore menù).I would not break my zaurus.Thanks so much

Hi,

if you did a NAND-Backup before installing u-boot you should use this file. Or, alternatively, download a NAND-backup file from somewhere, e.g.

Trisoft

Trisoft download page

The filename is SYSTC860.DBK for a zaurus C860.

Put this file on a CF-card, insert the card in your zaurus and then enter the Diagnostic Menu as described earlier. From the Menu choose "NAND-Restore" and follow the steps, there is not much you can do wrong during this process. Only keep the power connected. After you are back in the Diagnostic Menu choose Reset from the Extra-menu.

Cheers, Jan

Hi.
Thanks for ther answer.
This evening I try as you tell me.If I have problem I ask in this Forum:Thanks you very much.Maybe in the future I will try pdaxrom.At the moment I prefer cacko.

I cant use a sd card to do a nand restore?

I'm restoring the nand flash with sd.

I installed cacko.Thanks very much

I've just tried to do this. I get a screen saying

"NAND Restore from CF
file:SYSTC860.DBK
not exist file"

The file (from Trisoft) is at the root of a 256MB CF card which is reported as vfat. I had trouble getting the all-uppercase filename (had to mount with option "shortname=mixed") but it still isn't found. Any ideas please?

The card needs to be formatted as FAT16, not FAT32. I.e. you want to do something like:

Thank you! I'll try again this evening.
