I have the same problem.
My box is black edition, bought t2 years ago directly from indonesian reseller.
Since I'm a consultant I ligve aroundtheworld and I could not use the box for at least 1 year. now I'm in germany.
I installed version 1..2.0419, it was saying box fiormware had to be upgraded. pressed the button and got locked because of the country.
No when I plug my box,m it's not recognised at all and has blue and red leds blinking.
so I guess it's stuck in DFu mode??
How to flash it?
Thanks,
Paolo / Excessive
