Hi everyone! I bought this device as MK809II. Before I was not familiar with Android stick computers so I did little market research and bought this mini PC. When I plugged it into my tv a black screen saying 'TV BOX' in white appeared, after that a round loading circle( like cyanogenmod ) with android inscription in the middle. In the settings I paid attention only to the fact there was no mention about RK3066 but something about RK30SDK and the stick computer had about 500mb internal storage and 5,82gb NAND flash. After installing some basic apps I went out of internal storage and found impossible to move from it to the NAND. I tried some different apps but all required ROOT rights. I did my research and found a CWM upgrade which leв to crash my device after 30% of the upgrading process. I downloaded: - RkBatchTool - Rom Flash Tool - Android SDK - PDANet RKBatchTool and Rom Flash Tool after installing the images give me no errors and everything goes succesfully until i take of the device from the computer and try to connect it back... it doesn't appear nor on the PC nor on the tv(no signal). When I put it in boot mode it's green in RKBatchTool and says 'found RKAndroid loader rock usb' in the Rom Flash Tool respectively. Can't 'switch' or 'reboot to flash mode'(not msc device) Also can't install properly PDAnet because it cannot find any device and is impossible to run adb shell for the same reason. I have no clue what should be done for unbrick it! Please help me to find what device really is(I have some doubts after comparing it with pics on the web and system information in the settings) to find the proper guide,drivers and boot image. Also i would like to know how can I turn it in a mass storage device for my PC.
