Firmware update, bluescreen, fixed, now SD card issues



  • I installed the CR Touch, but the wrong firmware which bluescreened my Ender 3. I finally got it back to the original firmware and added the right CR firmware, but now not only is the screen glitching but when I insert the SD card it says card inserted but the menu says No TF Card. I bought a new SD card to make sure it wasn't the stock card that came with the printer, and it's the same issue. I even downloaded the SD Card format tool to ensure it wasn't Windows formatting, and no luck.

    Is this printer hosed and I need to return it, or is there a simple fix for all of these issues I haven't been able to find in my online searches? Thanks!

    Did you update both controller card and display firmware?
