I downloaded the Ender 3 V4.2.2 Firmware today to update my Ender 3’s after update the screen went blank and remained blank… This is the same firmware I have been updating my printers to. I tried a few troubleshooting steps I found on the web, none of which resolved the issue, so I downloaded a different 4.2.2 firmware from the site and the Ender 3 Max 4.2.2 firmware resolved my issue.
