How to unpack mk808 Firmware.

[tatubias]

This a basic tutorial how to un pack it. (i have not tested yet)

sample rom: Download update_mk808_pad_204j1.img for free on uploading.com

rockchip wndals tool: RK29xxImageTools_v2.1.zip - 4shared.com - online file sharing and storage - download
mirror: https://www.dropbox.com/s/nv8x91z2yc...Tools_v2.1.zip


1 - Download the rom
2 - Download rockchip wendals tools.
3 - Unpack Rockchip Wendal tools into a directory
4 - copy to the root of the direcotry were you unpack the wendals tools and remane the update_mk808_pad_204j1.img to wendal.img
5 - Run Runme.bat
6 - now the scritp will auto split the firmware. in to:

• boot.img
• kernel.img
• misc.img
• recovery.img
• system.img it is ext3 this file system.

then you will get the system.img and you can mount it into your linux Vm.

in y ou VM to mount the system.img you need to make a directory may be in /mnt

cd /mnt
mkdir system

go to the directory were you have the system.img and type.

sudo mount -o loop system.img /mnt/system

if you get errors you can try the following specifing the filesystem.

sudo mount -t ext3 -o loop system.img /mnt/system

then you can edit add remove anything you want, then you need to un mount the system.img.

get out of the system directory and run.

sudo umount system

then copy it again to the windows pc. into the temp directory were it was unpacked. and run again Runme.bat option 2 to repack.

i dont know if it will boot i dont have the device but the tutorial works :P

Thanks for the instructions, the sample rom you linked to is the factory default stock rom/firmware?
Can a firmware be dumped from device somehow?

Its a factory stock rom. It is the one I posted before.

Prbably do a dump of the rom can be made using adb but as I don't have the devie I can't do much.

The tutorial should work for the UG802 too. You need to use a ug802 firmware only

tatubias/forum,

Thanks for posting these instructions. I would like to save the current firmware on my MK808 before making any modifications. That way, I will have an undo, in the event that something goes wrong. Is there a procedure that can help me with that? Thanks in advance.

Check in xda forum there are some apps that can do that. Also in rokomagic forum you can get the original firmware.
