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.
