Hi! New Ender 3 V2 owner, trying to upgrade firmware, stuck on black screen

I tried to upgrade my firmware on my ender 3 v2, and now it’s stuck on a black screen, I can’t seem to figure out why as well, any help would be appreciated!

Have you verified that you can still read the SD card on a computer?

  • Even so, try a different SD card.
  • Try installing the manufacturer’s default firmware, just to confirm your firmware isn’t buggy.
  • I’m fairly certain that the E3V2 doesn’t have the filename restrictions that earlier versions had, but just to be safe, try just naming the firmware “firmware.bin”

Thank you! That actually helped me solve my issue!!

Why are you upgrading firmware on a new Ender 3 V2?
I would suggest learning the printer before upgrading anything.

Upgrading the printer was one of the recurring things to do when getting the printer - it’s been working fine now.
Edit: the firmware was also wildly out of date so it doesn’t hurt to update it.
