We found out, that the MK808B has more Versions out on the Market which have not the same ROM ! So it seems there are really more Versions on the Market... I found out, some Differences on the MK808B ! Original One has... only one big Wifi Antenna and the Second are 2 Pins on the PCB which connect to a small Metal Plate (30% of the other Metal Paper Size) on the Case. Wifi CHip RK903, RK902, RK901.... a heatsink on top of the RK3066 and the Clone #1 has no 1080p and 720p support from the Kernel Heatsink on the RK3066 Wifi Chip Mediatek !!! (Orange Board) MT5931 much bigger then the other... PCB NAME: "SunVell 808" I name it Clone #1 Also you might know, that there is another Clone #2 on the Market, but I have not enough Informations for you yet, maybe soon. Check back for Updates here... The Clone#2 has no heatsink on the RK3066 also MTK Chipset It is possible that on this Clones the Kernel is locked, so you can only flash a correct ROM. Don´t know if these Things are the only Differences... First is the Version with a green PCB from Geekbuying the Original One like this: It has 1 Wifi Antenna and on the other Side 2 Pins connect to the Case... The other Version spotted is the Blue PCB, also seems Original. If you see more Informations about the Differences, post here...
