I have got Rk3066 RBox Android Device with android 4.2.2 and external display connection through HDMI Cable.
It has 4 standard USB ports but no MicroUSB ports. I want to root this device but cannot connect device to Windows for adb connection. When I installed Antutu BenchMark on this device it showed that the device has root access. I installed Terminal Emulator on the device but cannot execute command "su" (giving error uid not allowed to su). The "su" file exists in /system/xbin location. I also checked all versions of Framaroot app with no success. Please help.
Thanks in advance.
