Hi, I was using an Ender 3 V2 for a long time until a friend reached out and said he has a V3 KE for me to upgrade from my current set-up. The only problem is, I think the touchpad has been upgraded to a Nebula pad, and the firmware seems to be GuppyScreen 0.0.26-beta. I haven't been able to find any good guides on how to uninstall the firmware and revert it back to the latest version of the standard firmware. Can someone please point me in the right direction for a step-by-step guide to reset it back to basics? Thank you.
