    I bought a MK808 from ebay.de. (http://www.ebay.de/itm/200866412620?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649#ht_4207wt_958)

    At first, it worked well. But one day I couldn't reboot, so I had restored with new Firmware. (Final one is the latest official version from this site. - new update_mk808_301 which is released January 10, 2013)

    But still I can't connect to WIFI. (WIFI scan menu is disabled and Mac Address is not displayed)
    I opened the case and found that mine has one big Antenna with grounded line and 2 small pin in other side.
    It is not supported Bluetooth, but the shape is just same as these images. (Except only Bluetooth sticker)

    I've tried to ask to seller to solve this problem and they send me two firmware version (one is MK808 and the other is for KM808B) But with MK808 (update_mk808_box_300j1.img), it was not worked and MK808B I even I can't install it with error. (update_mk808b_400j1401.img)

    Does anyone help me.

    Thank you.

    Did you really have the RK WiFi Chipset ??

    Look at the First Picture, theres a Metal Plate in the middle of the PCB, this is the WiFi Chipset... Which RK did you have 901 ? 902 ? 903 ??

    If you have One of them, this should be the correct Firmware: http://vondroid.com/threads/mk808-official-firmware-10th-jan-2013.4849/
    Otherwise, can you turn your WiFi on or not ?

    Yes, mine is RK903.
    And as I stated in my previous comment, I had installed the firmware but couldn't activate wifi.
    Whenever I tried to turn on wifi but it turns off after 10 seconds.

    It was MK808B.
    I installed the latest MK808B firmware and it works now.

    Thank you.

    Great to hear. Normally if something didn´t work try to reflash again and if this don´t work you should have the false ROM.
    But if it works, everythings fine.

    Hi all,
    I have exactly the same stick as shown in the picture above but without the blue tooth. Everything works except that the wifi reception is poor. When I opened the stick the wifi antenna's contacts are hidden under the heat sink sticker. The pcb also looks different from all the other pictures that people have posted so far. My question is have the company fixed the wifi issues with the new redesigned pcb or do I still have to remove the gnd. from the antenna?

    Thank you.

    Think they did nothing, because more rk3188 quad devices are coming up now. Look at our news to get more information. I post news of tv sticks every time I can...

    Well then does someone has a better diagram or instructions as to which one of the contacts is ground. There are no markings on the board.

    Thank you.
