In terms of taking a new update
Wait for the next one to come out.
It will have more things fixed and PVR feature added.
As for the Bluetooth not working, this was a misprint on the giftbox packaging. The 586 does not have Bluetooth.
We use the S805-B chipset on the 586, which means it is capable of Hardware Decoding Dolby through HDMI. So this should work for you.
