I bought a device from ebay. It should be a a CX919II J22 unbranded.
I had issues with playing HD movie and decided to tried using a new firmware. The "stable" one (Armookie MT cyxtech_rk31_CX-919II J22_140509_8G2G from factory.zip) doesn't work at all for me. After successful restore the device doesn't boot. However the kitkat could boot up but wifi and bt don't work. Morever it boots slowly as hell.
Any help would be appriciated. I didn't do any backup unfortunatelly
