i'm havīng problems installing the latest update, the process is as follows.
- Go to settings > system > update console
- Download update.
- Xbox reboots and Xbox logo flashes
- power brick light turns orange and then dull white
- Xbox does not power back on
The only way to power back on the console is to pull the plug from the power brick until the light goes off and reconnect.
Once the Xbox comes back on the update is still available.
I've attempted to update three times this way and the console attempted an automatic install over night which resulted in me having to pull the power to get it back on.
