Sony has announced that you can now update firmware for the DualSense controller using your PC instead of a PS5 console.
To get started, you must first download the DualSense firmware updater to your PC and save it to your desktop or other location. You can download it here.
You need to make sure you’re running Windows 10 (64-bit) or Windows 11 for it to work.
After installing the updater, run the installer file and then follow the on-screen instructions to install the app. During installation, you may be prompted to download additional software required to use the app. So just follow the on-screen instructions.
After the app is installed, run it and use a USB cable to connect your controller to your PC, then follow the on-screen instructions to start the update. During this time, do not turn off your system or disconnect the USB cable.
A message will appear when the update is complete. Select OK to complete the process. As simple as that.
You can only update firmware for one controller at a time. So if you have more than one, you’ll need to do this for each controller individually.
From time to time, Sony will release updates to the DualSense firmware that are required for the controller to function properly. You will be notified of new firmware updates when you update your PS5 system software to a newer version or when you launch the Firmware Updater app.
Sony “strongly recommends” to always install the latest update after its release due to potential security risks and a possible disruption to the proper functioning of the controller.
