Got the Echo, it replaced an Xbox360 that was running as an extender. Upon firing it up, it seemed to update OK. I got the WMC code for adding it as an extender.
The firmware listed was 2012.1127.2101, is that the latest?
After entering the code, it seemed to link up fine to the Host PC. The MC menu was displayed on the Echo/TV, but the remote keys didn't seem to work; I couldn't move around the menu.
Off key worked fine (like the On key did when I booted it the first time). Now when I hit the On key, I get the Ceton logo, and underneath 'recovering...'.
And there it sits, probably for all eternity, as least as far as I can discern.
Also, the Echo WMC plug in won't show up in Extras Library. Bummer. I put in a Support Ticket. Now I wait.
***Ahh, I see you have to access the Plug in from the extender, not the Host PC, do I have that right?***
***Well, bummer, RMA time. Guess the Xbox360 goes back in place***
