Updates for this device are coming in. Hardware of Imito Mx1/Mx2 is similar
to that of MK802IIIS and hence the firmware released by Rikomagic for their
devices is working perfectly fine with Imitos. I recently flashed the latest
4.2.2 firmware update from rikomagic on my device (Imito MX2) and its
working just fine - Wifi/Bluetooth are working without any issues.
