Hello! I`ve just received this

http://www.geekbuying.com/item/UStick-MK809-PLUS-M805-TV-Dongle-Quad-Core-Stick-1G-RAM-8G-ROM-Android-4-4-2-4G-5G-WIFI-Blutooth-Miracast---Black-341042.html

hdmi stick.
Tried to upload new firmware via sdcard, but it failed. And I got a boot loop as a result
Ok, then I opened the box and tried to get to the recovery mode with 6 and 7 pins (because there is no reset button and no volume buttons to navigate in the recovery menu), also there is a mistake in the manual at geekbuying blog about pins(you have to count them from other side)
Then I managed to get the recovery tool to reconize the device and i tried to flash it but it gives me errors

So, can anyone share a working method to restore my firmware or working original firmware from this device and flashing software?

maybe i can flash some custom rom just to make it boot normally?
