Ripping Root Filesystem From The Original Sl-c1000, Want to modify original filesystem on sl-c1000 Options

[Alexandr]

Hello,
I want to take the original Sharp ROM and make same modification on the filesystem and flash it back.
The current problem I cannot find original Sharp ROM with initrd, but as NAND backup only. Possible ways:

1. Extracting the filesystem from the NAND.
Ths is not working properly for me (the file system is corrupted, files missing).

2. Restore NAND backup and rip root filesystem
2.1 Rip image: dd if=/dev/mtdblock0 of=/mnt/cf/zaurus.rom
2.2 This is jffs2 (?) image.
2.3 Tring this http://www.oesf.org/index.php?title=C3000_...or_the_SL-C3000, I receive error message: mount: /dev/mtdblock0: can't read superblock

Any ideas how to make it work?
Thank you.

I suspect you need to mount the mtdblock device partitions as RW or RO. A Google on the subject of ripping Z roms or a further search of the forums and our Wiki might well give you the answer you are looking for.
