Bad news! When I started the CPU upgrade, the status stayed at "Erasing.." forever (more than one hour), I shut down the receiver after that, and could not be able to start the upgrade again. The console screen kept showing "WAIT DATA", and I could not turn on the receiver again.
Good news! I still have time to exchange for another one.
Vancouver, how long did it take you to upgrade the CPU part? Thanks.
The cpu upgrade took about 6 min, try flashing it again and follow the detailed instuctions. Good luck.
