My xbox series s sync button isn't working and my brand new controller is just blinking and...

Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you with your concern.

Can you please try connecting your controller using a wired cable? Please check if there is an update as well by following the steps below:

"1. Press the Xbox button to open the guide, select Profile & system > Settings > Devices & streaming > Accessories, and then select the controller you want to update.

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

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

Also, please perform the steps below accordingly:

"​​​1. Turn off your console by holding the Xbox button on the front of the console for approximately 10 seconds. The console will turn off. ​​​

2. Unplug your console for 5 minutes.

3. Turn your console back on by pressing the Xbox button on the console."

Hello Dominic S, my name is zahir.

Have you tried to use a usb cable directly to the xbox and try to do a controller update.

A fast blinking light indicates that your Xbox controller is trying to connect to a console or PC. Slow blinking usually indicates that there is likely an issue with the battery pack. The most common causes of a blinking Xbox controller include: The controller battery is possibly drained or dying and must be replaced.

How do I resync my controller?

Turn on your Xbox One console and hold down the “SYNC” button on your controller simultaneously with the “SYNC” button on your console. Hold these buttons down together until the light on your controller begins to flash rapidly, then release both “SYNC” buttons.

If this does not work please use link for controller service.

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 had the same problem but I sent a series s controller and I got a one s controller in return, and the series s controller I sent came with my Xbox, brand new

Thanks for the reply. Interesting, I did not know that it was "wirelessly" connected while connected to a USB C Data Cord. As soon as I unplug, it stays disconnected (in sync mode the controller also keeps blinking then turns off). If this is right I don't know why I also can't sync any of my other Xbox controllers to the series X unless connected with a cord (works on an One X controller also, stops when unplugged). I don't know why the sync button (blinking) stopped operating all together.

I replaced my batteries and tried to pull and place back in earlier with no luck. I also updated the controller as I set up as new.

The interesting thing is I am able to use the series X controller perfectly on PC wirelessly with windows 10/Xbox PC adapter. I have no problems on PC wireless.
