I'm struggling as well. z4root doesn't work. neither does gingerbreak. superoneclick claims success (although I can see errors in setting permissions and copying files), then wants to reboot the device where it just hangs and has to be reset. If i try other superoneclick methods it doesn't reboot but nonetheless I don't get root...

Looking at your feedback, you seem to be doing the things right.

I should buy a 9 G2 soon, I will tell you how it goes on my side...

None of those roots will work.  Same as the 10 G2.  /system is a cramfs file system and cannot be written too.  However I do recall using a tool that installed su or busybox in /data/local or something like that.  It gave you a simi-root but again NO writing to /system as it is impossible!

I do not have ADB installed myself yet but I thought it was possible to at least mount your own created ext3 system.img and then copy all the files from the tablets /system to that?

Also there is a good darn chance that /backup already has the update.img sitting there!  My 10 G2 did.  All I need it that!  /backup is not mounted by default so in ADB mount it and see if update.img is there.

 

Dang I guess I am going to have to install the SDK and java BS and have a go at ADB ūüôĀ

I rooted the 10 G2 without it but it might have saved me a lot of trial and error.  Now might be the time to install it and strat learning it.

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.

Write access should be permitted to /data/local, try to adb push rkdump there

Make sure you have root before running rkdump

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:

http://forum.xda-developers.com/showthread.php?t=1286305

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.
