Hi,
I found a working souce of usb adb driver (after many tries and fails) at: http://minix.com.hk/downfile/RK_DriverAssitant.zip
it comes with an installer which works!
After this a basic script provided for an easy installation of supersu and busybox:
search for RK3188_ROOT (or use http://www.mediafire.com/download/dzx599tkq0rdehl/RK3188_ROOT_Tool.zip)
