One final tip, before going down the hardware path, you said you have tried a factory reset, did you try installing a newer (or same) version of the firmware with the pin reset method?

Best thing to do is a search on this site for 'replacement power supply'.
Here is a good place to start.

How would I understand if the Himedia Q10 Pro I'm having is an European or a Chinese version?
Also may I expect any OTA update?

Hi,
IS there any update to my post? It has been almost a week since I posted my queries.

In the FAQ! Hint: (last item in the list, under Misc) * Differences between Q5/Q10 Pro Chinese and European/international hardware? See here: http://www.futeko.com/newforum/index.php?topic=1175.msg9321#msg9321
