Problem after upgrading firmware to Version 1.04.31_V

Will no longer eject USB hard drive after firmware upgrade.  The loop screen just continue to rotate and also can not turn it off using the remote control.  I have to pull the power source to turn system off.

I’ve learned from some people that the answer is to go back to the firmware you used previously to the updated firmware, then upon completion, reinstall the latest firmware again.  It takes a little time, but it seems to work for most people.
