NAND Backup/Restore
« on: December 11, 2003, 07:47:07 pm »
How do I perform a NAND backup and resotre on my C760?  Can it be backed up on a 256mb SD card or does it require a CF card?  Also I only have 128 CF cards.  Would that suffice?

AFAIK you can flash the Z with a FAT-formatted SD card, but for CF it doesn\'t matter if it\'s formatted as FAT or EXT2..

To be on the safe side I would say use a CF card for NAND backups / restores. A 128MB CF card (which covers the entire flash storage area of the Zaurus C760) should be around the £25 / $45 US / €35

How do I get to the backup/restore screen?  Would a reboot bring it up?

Offroadgeek,

Just a comment, but the steps in the document to get to English Service Menu never worked for my 760. I don\'t think you need the \"re-insert battery\" and \"lock\". Thanks to the X11 rom, I\'ve been going back and forth  

The easiest way I found is
1) Unlock
2) Remove battery and power
3) Hold D & M and connect power
4) Continue to hold D & M while pressing on/off button.

No locking or battery required.

My NAND backup for my C860 is 138543120 bytes (132MB) on a CF card, but I\'m not 100% sure it worked correctly. The progress bar went all the way across the screen, but then nothing seem to happen. I left it for a few minutes longer then fiddled with some buttons (don\'t remember which) and got  back to the service menus. Found the menu option to exit and did.

Don\'t worry about it.  I\'ve been doing nand backups for a few weeks (and restoring then) and I find that after it says \'OK\' I press the cancel button to get back to the service menu and then power off.

The data is stored correctly.  By the way - that is the right size for the file.

hmmm.  You can flash ext2 on a CF?

My c700 now seems to not want to see FAT formatted Cf cards for flashing...
I can\'t seem to convince it to see the card -- and I have flashed many times.

Did you format it to FAT and not FAT32?

Just did my Nand backup on a 256sd card.  Seemed to work fine.  This is the size for the C760 135,297KB (Systc760.dbk)

I tried to do NAND backup from SL-C860 to Lexar 256 MB SD Card (factory formated) but I failed. After 20% got answer \"Backup failed\". I used Backup/Restore application.
Then I bough a Lexar 128 MB CF Card and everything went smooth.
Is it possibly Lexar formats SD to ext2? Actually I was not going to buy CF card since I wanted to have WLAN CF card. So it was additional spending.
Is only way to check format to install fdisk?
