Hello,

Thanks Qbspin! Following Qbspin's instructions, and using cramfs tools I could unpack both ro.fs.v5 and root.fs.v5 (with some errors though):

ro.fs.v5

Code:

root@ubuntu:~/cramfs-1.1$ ./cramfsck -x /tmp/ro.fs.v5 ../firmware-tools/ro.fs.v5; ls -Rla /tmp/ro.fs.v5
warning: file extends past end of filesystem

Sadly, It doesn't work with the user.fs.v5 (i get a ./cramfsck: superblock magic not found). Does it work for any of you? I guess this file contains all the libraries required to boot the system and parse/view the ebooks, don't you think?

To be honest I don't know if the inode structure is correct. As far as I know: File sizes are limited to less than 16MB. (via wikipedia). That adobe file may be related to the Adobe® Digital Editions software..
