First of all, Do it by your own. If you brick your tab I'll wash my hands.
Thanks to DoomLord for his work in the Rooting System.
Well I have created a rooting toolkit for our tabs based in RK29 chip. Please give feedback if it works for your tab.
What it does ?
1. Install the SU (3.1.1) and Busybox binary.
2. Install as system apps the Superuser apk and the BusyBox Free.
3. Done !
If adb drivers doesn't works with your device find another ones, I canno't give support for all RK29 tabs.
The Uploaded ADB Drivers work with my older post.
If you find another ADB drivers for your rk29 tab upload and I'll post them.
How works the root toolkit?
My root toolkit works using android emulator trick of thirty party project based in DoomLord.
While entering the security creates a temporal folder on the tab to save the files.
Then it copy the su to bin folder and busybox to xbin. After that it changes the permissions by command chmod of the binary to be runnable.
Then it just pushes the two apks to system/app folder. Those apk will be installed as system apps in the next boot.
Finally it cleans a bit the temp folder and you are done.
Give a thanks if it helps and give feedback!
