Not being able to restore hub to lego firmware

[sunnysideup121]

I tried restoring the Lego firmware on the spike prime hubs which has the pybrick firmware installed. The Bluetooth button blinks all the colors - pink, green, blue, off but when I clicked the restore button it my hub doesn't show up in the window to restore. Can someone help? I followed the instructions on the site.

Usually, if the hub doesn't show up, it is due to a bad USB cable. Some USB cables are for charging only and can't be used for sending data.

Does the hub show up in the Windows Device manager?

I'm using the cable that was provide with Spike Prime. I also don't see the hub on Devise Manager. What kind of cable do I need to make this work?

The one that comes in the LEGO set should is fine, assuming it hasn't been damaged. But if nothing is showing up at all in the Windows Device Manager when you unplug the hub and plug it back in, then something strange is going on at a hardware level.

If the driver isn't installed, you should see this:

But if you managed to install Pybricks firmware using the same computer, the driver should still be configured to be using the WinUSB driver and look like this:

Can you try it on the same computer you've used to install Pybricks originally?

It should work on any computer, but certainly on the one you used previously, because the installation and recovery procedures work exactly the same.
