Tethered boot works fine but after that aTV hangs

Hi

 

tethered boot works fine. but:

 

  • when the network cable is connected, aTV hangs in “setting time and date”

  • when network cable is disconnected, it boots up to the start screen (two icons, one is the firecore icon instead of the usual settings icon) but does not accept any remote IR commands.

 

I used the same IR remote to bring it into DFU mode, so the remote is fine.

 

Any ideas?

 

Thanks

hold down menu and the left button at the same time and poijnt it at the apple tv for about 10 seconds
