The reason this is possible is due to the “out of factory” state of the Logitech Revue boxes not disabling the UART port on the board and allowing access to a root shell in recovery mode. After discovering this we were able to reverse the update files and manually upgrade the Revue to the most recent update. The attached files are our output of all the effort put forward by our team. Also as a notice to anyone performing the update, we are not responsible for any harm that may come of your box as an outcome of running our scripts. We will attempt to help you with any issues you may experience and have tried to make the process as safe as possible. Also if you have any suggestions or ideas on how we can make this process better please feel free to drop by our IRC channel and tell us.
