"A320WH9330047" is FAKE DINGOO
If you bought dingoo recently, please check your dingoo´s serial number, it was printed in the speakers side of your dingoo.
If it is "A320WH9330047" , then you are one of victims of FAKE DINGOOs.
Recently , a bundle of FAKE DINGOOs share a same serial number: "A320WH9330047" (funny thing is it has different serial number printed in the box, so don´t only check the serial number printed in the box ).
In real dingoos, "WH" means white dingoo, "BK" means black dingoo.
Fake dingoos use uncertified charger , a client has report it is exploded , be careful.
The fake dingoo will be locked if you try to update the higher firmware version , such as 1.6 version.
Beta 1.6 version firmware can be download here:http://www.ccdang.com/DownSoft/?softid=4431&pathid=1
