Here are some instructions on how to dump a firmware of a Rockchip CPU based tablet.

Required Linux system, preferably an Ubuntu/Debian 64 bits (not running in a virtual machine like Vmware or Virtualbox).

You can use Steve (ttz642t) script to dump a Rockchip based tablet firmware:

[[** please register to see this link **]]

It uses rkflashtool from XDA: [[** please register to see this link **]]

We have compiled a package with binaries (64 bits) to make it easier for you, so what you need to do is open a console/terminal in Ubuntu, then download the archive using:

wget [[** please register to see this link **]]

then unpack it with

tar xvfz Rockchip_dump_Linux_01.tgz

change dir:

cd Rockchip_dump_Linux

install libusb:

sudo apt-get install libusb-1.0-0-dev

(you'll need to enter your root password when prompt)

Plug the power connector and the micro usb cable on your tablet and put your device in flash mode using a paper clip in the reset button (see [[** please register to see this  link **]] article to discover the right "key" combination for your tablet model to enter flash mode)

Finally run the dump script:

perl ./an10g2_dump.pl

You should have the dumped files in a subdirectory named after the date/time the script was run in the format like 20120702_1238

We'll need the backup.img file from that dump subdirectory.

Thanks to Steve (ttz642t) for the Rockchip and dump perl scripts

In case you don't have a Linux machine available to run this firmware dump method, you can also use an [[** please register to see this link **]] that runs on any operating system that has ADB (Windows, Linux, Mac).

Thanks exelletor for this fine tutorial Wink

Many thanks for this tutorial. It worked like a charm on my Arnova 9 G3. One sidenote: you need to set the .pl file to be executable with

chmod +x an10g2_dump.pl

before you can run it.

Dumb question: can I use the resulting backup.img file in the Rockchip flashing tool to restore my stock firmware? Or is there some sort of magic that needs to be performed on it before it can be used in that tool? "backup.img" seems to be the same size as the various custom firmwares available on this site, but I thought I'd ask before giving it a go.

The easiest option is to take apart the different images out of the backup.img file.

Check the tools from here:

[[** please register to see this link **]]

You'll need (on top of my head) : rkunpack and afptool.

Once you have all the image parts, just setup RKAndroidTool (available from [[** please register to see this link **]]) and flash your device.

Thanks for the info, admin.

I'm still a little confused, though. I got the RK2918 tools working and used afptool on the backup.img file. It produced the following files:

------- UNPACK -------
package-file  0x00000800  0x0000021B
RK29xxLoader(L)_V2.14.bin  0x00001000  0x0002512E
parameter  0x00026800  0x00000255
Image/misc.img  0x00027000  0x0000C000
Image/kernel.img  0x00033000  0x006DD030
Image/boot.img  0x00710800  0x007BC000
Image/recovery.img  0x00ECC800  0x00958000
Image/system.img  0x01824800  0x0AF5E000
SELF  0x00000000  0x0C783804
Skip SELF file.
update-script  0x0C782800  0x000003A5
recover-script  0x0C783000  0x0000010A
UnPack OK!

As you can see, system.img is the big file, about 175MB. But it doesn't appear to have the all-important "RKFW" header, that all the custom firmwares ("update.img") seem to have.
Which file should I use? Or what else should I do?

Or, is there some documentation of the RK2918 tools somewhere?

Well, you should be able to flash all the firmware image part (system, boot, recovery,…) using RKAndroidTool as I mentioned. Just point the bootloader, parameter file and each image to the files you extracted and you should be fine.

For Rockchip firmware related info, you can learn a lot working with the tools I mentioned and experimenting by yourself. This [[** please register to see this link **]] also has some info.

Cheers.

you need to recompile the tools and use it on its own.

as i said earlier, the tools that is provided in the first post is more intended for rk2918 chips, not on the new 3066 and 3188, for these new ones, you need to recompile
