PlayTab Pro

Hi, just tried it on my PlayTab Pro.

Doesn't finish successfully:

K:\Dowloads\Root_RK29_Tab_Toolkit_1.3\Root RK29 Tab Toolkit 1.3\RooT>runme.bat
RK29 Rooting toolkit (v1.2)
created by SferaDev for our RK Tabs (Based on ICS)
from the work of DooMLoRD using "andorid emulator" trick
Credits go to all those involved in making this possible!
----------------------------------------------------------------------
----------------------------------------------------------------------
This tool will:
(1) Root your RK29 tab
(2) Install Busybox + Stericson's Busybox Free
(3) Install SU binary (3.1.1) + Superuser.apk
(4) If there is low free space, the tool will remove Google Maps.
----------------------------------------------------------------------
Make sure you do this:
(1) Install the drivers of the folder
(2) Power on your Tab
(3) Turn Mass Storage OFF
(4) Enable "USB DEBUGGING" from Developer Options
(5) Enable "UNKNOWN SOURCES" from Security
(6) connect USB cable to your Tab and then connect it to PC

When you finish all above press enter...
