Hi

For your info, I was able to get a dump from the mtdblocks on my non-rooted 10G2 device (using adb shell).

After that I used rkdump (http://androtab.info/rockchip/devel/rkutils/)

Download and instructions can be found on that site.

For info on my 10G2:

cat /proc/mtd

 dev:    size   erasesize  name

 mtd0: 00400000 00004000 "misc"

 mtd1: 00800000 00004000 "kernel"

 mtd2: 00400000 00004000 "boot"

 mtd3: 00800000 00004000 "recovery"

 mtd4: 10000000 00004000 "system"

 mtd5: 10400000 00004000 "backup"

 mtd6: 07400000 00004000 "cache"

 mtd7: 10000000 00004000 "userdata"

 mtd8: 00400000 00004000 "kpanic"

 mtd9: b4400000 00004000 "user"

Rkdump commands:

/data/rkdump /dev/block/mtdblock1 /sdcard/kernel.img

 /data/rkdump /dev/block/mtdblock2 /sdcard/boot.img

 /data/rkdump /dev/block/mtdblock3 /sdcard/recovery.img

 /data/rkdump /dev/block/mtdblock4 /sdcard/system.img

 /data/rkdump /dev/block/mtdblock5 /sdcard/update.img

Important to know, do not enable the mass storage on your device, otherwise it cannot write to /sdcard and you will get a permission denied.

If it works on a non-rooted 10G2, it should work as well on a non-rooted 9G2 as well.

I see you have ADB and your device is listed like it should be.

Copy rkdump on your computer in the folder where the ADB.exe can be found (plaform-tools).

Try this, it should/must work:

adb push rkdump /data/

or to another location:

adb push /sdcard/

What do you get after executing the following command: adb shell

Do you get a # or a $ ?

If it's a $, write exit and try then following command: adb root

This should launch the adb deamon in root mode and should give you a # when running adb shell

To allow rkdump to be executed, write this when you are in adb shell

chmod 755 /data/rkdump

This will set the correct permissions on the rkdump file.

That explains a lot, so you're really need to root the device first.

Have you already tried to install PDAnet? Can you do this? (http://junefabrics.com/android/index.php)

I had to install and run it in order to get adb working.

Maybe it did some voodoo as well on my device and rooted it without me knowing it.

I can't recall doing any mounts on my device.

It also can be that archos/arnova started to block us.

Because enabling/disabling adb root access can be done in the boot.img file.

I think they've set this parameter ro.debugable to 0 instead of 1

Since this is the case, you cannot dump your image through rkdump.

Can you try another thing?

execute the following commands:

adb shell

su -

Do you get a # or an error message? I presume you will get an error message, but you'll never know if you don't try.

If this all doesn't give you a #, I guess we'll have to wait for the first update.img from arnova.

Maybe not all hope is lost:

This is a flashtool for RK2818 and RK2918 for linux/mac and like it seems, it should be able to backup images from your device to your computer, without the need being a root user on the device.

The "hard" part, you need to know the offsets, but that can be found by the instructions in the first post on the site.
