You can have the remote turn off both the STB and the TV by using a key code so you dont have to have the TV plugged into the STB.
Program remote to power TV & STB at the same time
1) Press and hold the STB key. 2) While holding down the STB key, press OK. 3) Release both keys. The device keys will blink twice. 4) Press 9-7-7. The STB key will blink twice. 5) One after the other, press each device key you want the Power key to control in the order you want to turn on or off. Selected device key will blink twice after each pressed. 6) Press OK when done. The STB key will blink 3 times to indicate success in programming.
There is no way to stop the updates and global resets, so this is the only other solution to your problem.
