I have a currently bricked ATV 1000 clone that I am trying to unbrick, an MyGica ATV1000 that I am using and experimenting with and last Friday I received an Enjoi ATV 2000.
The ATV 2000 came with all the cables (including a HDMI cable) and stuff as well as a HDTV USB dongle with its detatchable indoor mini antenna.
It came with Android 2.3 loaded and 20111102 firmware and its associated apps.
I am currently checking out the ATV 2000 performance.
It was quite difficult to boot up initially and impossible with the HDTV dongle inserted.
The dongle works well with an external antenna and picked up all 26 channels where I live.
The only problem that I have experenced so far other than the booting, was that the TV box froze on occasions when watching TV, the TV froze and the TV box froze and I had to unplug and reboot.
This occurs from 40 minutes to 2 hours after starting to watch.
The HDTV dongle appeared to be a standard USB dongle so I tried it in my PC but although recognised and identified, I could not find any drivers for it (Yet!).
Addendum: Now found drivers on Geniatec web site and workin well on my PC.
So I then tried it with the ATV 1000 and HIDTV 1.9.2 and it worked flawlessly without stopping or freezing the unit.
So what is the difference between an ATV 1000 and an ATV 2000, to me its the mini HDTV USB dongle.
It appears to be a Geniatec S119 mini DBV-T TV Stick. So all you have to do is to plug in a S119 dongle and load up the latest HIDTV app to turn your ATV 1000 to an ATV 2000!
Since the ATV 2000 is regularly freezing with the dongle (and is difficult to restart) but not the ATV 1000, I suspect I may have a faulty TV box. I am currently trialling it and before making a decision to return it or not. (Addendum: The freezing of the TV box has been solved. It was heat related. I sat the unit on my amplifier due to access and space restrictions with the HDMI cable. When I swapped it to where my ATV 1000 was, no more problems.)
