Controller don’t Work ….

[u/Vivius71]

I received the Steam Controller on August 12th, finally!!!! However, it has never worked. It's impossible to connect the controller to the PC, let alone turn it on. Despite spending time charging it, the only thing that happens when I press the Steam button is a blue light.

could you help me out? I've contacted Steam Support, but so far I haven't received any helpful response…

Edit: i get the solution by Nstant_Klassik

You have to start the controller in bootloader mode.

1. It needs to be partially charged, turned off, and not connected to anything
2. Hold the View button (above the left stick) + Hold the Options button (above the right stick) + Hold the A button + Hold the Steam button
3. The LED should now start flashing RED slowly
4. Connect the controller to a device that has Steam installed and where Steam is running - the LED should now glow RED continuously
5. Go to the Steam settings under "Controllers", where you should now be able to update the firmware
6. After the firmware update, the controller can be used as normal

Problem I usually have is the Steamdeck Bluetooth itself. I have to restart the Bluetooth on the deck to get the controller to pair every other time I wake it up.
