I have an original RK-1. It boots green, blue, white. After a few seconds I get two green flashes. I see it on my android phone. When I click to connect, it never connects to the device.

I thought I might need an update, I created a the miniminal usb drive as described. I put the usb drive in the top port with an adapter. The device boots with the above sequence and does not load the update.

I will note that when I first got this unit, I was able to connect to wifi on the adroid and got through the setup to connect it to my wifi router. I wait for testnet and now I cannot access the unit now.
