Nokia N9 & rootfs.jffs2
 

Hi, i'm trying to mount a rootfs.jffs2 from Nokia N9 firmware.

I read many tutorials. And try a few times.

Errors:

mount: /dev/mtdblock1: Can't read superblock

Or small space in /dev/mtdblock1.


I read that N9 rootfs.jffs2 is the Ubifs, it is that right?

Anybody have done mount N9 rootfs?
