No it just updates the firmware :-)
Updating Firmware!
1: Plug Dingoo in to your USB
2: Copy the A320.HXF file to the root of you dingoo
3: Unplug your dingoo and switch it off
4: Switch your dingoo back on holding down on the control pad
5: let it update - do not switch off your dingoo till complete
6: you will have to set the language back through settings - its the sixth line down I think
7: In settings/about you can see your new firmware version 1.2 :-)
BTW: make sure you have plenty of battery life when doing this
