why wont my controller turn on and only blink rapidly when pressing the home button?

that sounds like a faulty controller the Bluetooth could be messed up there is no way to update on the app however you can try n see if it needs an update at a friends house who has an Xbox

Hello there,

This sounds like a familiar problem I had with one of my controllers a while ago. I found that the connection with the wireless adapter was much more reliable.

I recommend you have the PC forget the bluetooth connection with the controller, and have the controller depend only on the connection with the wireless adapter. When you disconnect the controller from the PC, it's possible that it will blink as though it is not connected to anything--this is okay.

Just reconnect to the wireless adapter only, without going through the bluetooth settings on your PC, by:

1. Press and hold the connection button on your controller until the Nexus button blinks rapidly
   
2. Press and hold the wireless adapter's connection button until the indicator light on it blinks rapidly
   
3. Wait a few seconds for the controller and adapter to find each other, and for the blinking to slow down and stop, indicating a successful connection
   

Best of luck, and stay safe! If this doesn't work for you, let us know.

When holding the sync buttons on the console and controller, the light blinks on the controller as if it is going through the syncing but then the light will start to blink steady or rapidly.........I did insert new batteries.....

I've had a similar problem. I have the Xbox X and the Elite controller. A couple of times, tonight is one, I turn on the console and it only responds to pressing the Home button and a couple of navigation commands. Hold down the home button to bring up the
power off console, controller, or report a problem menu, when one is highlighted it just blinks when pressing the A button. Only have had the X for a couple of weeks. Hasn't happened yet while I am doing something on the console. only after it is powered up.

Additional info:

When the console is turned off I hold the guide button to turn it on as I normally would (so the console is picking up the controller) but it wont synch, it still just blinks, spins as if loading then blinks again.
