I have spent the whole weekend trying to recover my Ender 3 v2 from a black screen issue triggered by a firmware upgrade.
I followed the directions from Creality, which later on, I discovered they are not accurate enough. I end up visiting the famous Reddit post. I also noticed that some people recommend using an 8GB SD card for the upgrade, as the FAQ from this forum.
I tried everything without any luck. I was wondering if there is a “hard reset” to return the fabric settings.
I’m open to any suggestions.
