This is a completely redesigned version of the MK802 HDMI Stick. The most stricking difference is that it has a male HDMI connector for plugging straight into a monitor or TV.

It seems that there are at least 2 different case designs for the MK802II. They both share the same innards though.

Everything else is the same as the manual build howto.

Tips, Tricks, Caveats

FEL mode

There is a hole next to the SD slot, under which is the "uboot" button which triggers FEL mode.

Adding a serial port (voids warranty)

MK802ii UART pads

Device disassembly

The bottom cover clips into the top cover, so you need to push the sides of the top cover outwards with your plastic tool. Start at the HDMI connector, as you have some purchase there. The mainboard is clicked into the top cover, and also requires some wriggling to get out.

Locating the UART

There are some minuscule pads on the bottom side of the board, as shown in the picture. You need to have decent soldering skills to be able to attach wires to those. More information is available in the UART howto.

Pictures

Also known as

The exterior is clearly marked as MK802, but neither shares the board or the case with that device, and the formfactor is slightly different.
