problem to dump rom on Freelander PD90

[feanor91]

Hello

I want to try to play with rom of my tablet but, I didn't manage to dump update.img (that seems to be called backup, by the way).

Here some informations:

root@android:/ # cat /proc/cpuinfocat /proc/cpuinfo

mtd9: 733a00000 00004000 "user"

it seems rkdumd didn't work on rk3066 as I found information on another topic, so what can I do? Rkbatchtool didn't allow to make a dump, the only thing I have is an official firmware from freelander that I can flash with rkbatchtool but nothing else.

Ok, finally, I found this:
[Only registered and activated users can see links. ]
that conduct to this
[Only registered and activated users can see links. ]

dump is made know, just see what to do with it...If someone can help, I'm total newbie in that world.

I got 6 files:
boot.img (16Mb)
checksum.md5
config.gz
recovery.img (16mb)
system.info.gz
system.tar (588.71 Mb)

What do next?

Now I'm stuck on wendal's tools.
Here is the content of my romdump folder
[Only registered and activated users can see links. ]

I use wendal's tools to try to unpack recovery.img as explain in this post [Only registered and activated users can see links. ]
but I get an error :

of course, Temp is empty, that is normal at that point as nothing works.
