My controller is blinking, sync not working.

Hi, Elijah! I'm sorry to hear you're having trouble with your controller. No worries, I'm happy to assist you with this today.

To isolate the case, let's check both devices your controller and your console.

Check for latest update on console first.

Settings > System > Updates & downloads > Console update.

Clear the cache:

Press and hold the Xbox button on the console for 10 seconds until it turns off.

Remove everything that is connected to the console

Wait for 3 minutes then connect the Power cord and HDMI cable.

For your controller, check for the latest firmware too:

Profile & system > Settings > Devices & connections > Controllers & headsets, and then select the controller you want to update.

On the Xbox Wireless Controller screen, select “…” to check the firmware version for your controller.

If it says “Update,” select Firmware version, and then follow the steps provided.

Try connecting your controller with a USB cable if it works.

Let me know how that goes.

Thank you!

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 been getting a problem with my controller lately. When I turn on my xbox and dont have a USB cable connected, it works fine, but when I want to use my USB cable, in a few seconds, it disconnects from xbox and goes into its blinking lights like
if it where syncing. Then it turns back on and does the same thing with the blinking lights. I tried syncing it to my xbox while the USB cable is connected, but when I press the syncing button on the xbox, it doesnt blink when its syncing. Try a different
cabble

I'm having the exact same issue. Controllers will work on another console, it can turn on the xbox and completes sync but the Xbox immediately loses the controller light and the controller starts blinking.

Everytime i press the button to sync the controller the xbox sign dont blink and when i tried it with the wire it also didnt work
