Why is XBox not loading Bright Green on startup

My xbox is constantly freezing when trying to open apps and games and also struggles to even startup. After waiting on the green loading screen i recived a E200 000000EF 00000000 error code. Why is this happening?

just scroll down and select E200

Hi Rosario,

It seems that your Xbox is still in Instant-On mode as it starts up on your dashboard. If you changed to Energy-Saving mode, the change may not have taken affect as in energy saving mode the Xbox will do a full boot up whenever you startup the Xbox and see
the green loading animation.

When you restart or shut down the Xbox through the settings, you are forcing your Xbox to do a full reboot and not be on Instant-On mode which is simply a low power or sleep mode when the Xbox is off and that allows a quicker startup straight to the dashboard.
Turning off the Xbox with the power button in Instant-On mode will just cause the Xbox to go into the low power mode and startup without the green loading screen.

Go back into your power settings as mentioned by Brad above and make sure energy-saving is selected in the middle column drop-down box. Then hold down the power button on the Xbox for about 10 seconds until the Xbox shuts down. Restart the Xbox. It will
do the full reboot with the green screen. Once on the dashboard, turn off the Xbox with the controller or by pressing the power button on the console and see if the startup reboots from the green loading screen.

My question is why are survivors green?

It looks more lime than green. Probably that colour because it's bright, make it's easy for the infected players to spot their targets.

I like a combo of Black and the Bright xbox green!

You can see the bright purple dot and just before that was a bright green one🤔
