Raise your hand if you’ve ever hit "Update" on your 3D printer and immediately regretted it.
Last night, I wasn't paying attention and updated my Creality K2 Plus. Instead of new features, I got instant errors and a printer that wouldn't print. To make matters worse, finding the right firmware to roll back to was surprisingly difficult because Creality hides newer stable versions under the "Old Versions" tab on their site.
If you are stuck in the same boat, I put together a quick walkthrough on how to fix it.
In this video, I show you:
✅ Where to find the actual firmware file you need.
✅ How to format your USB drive to ExFAT so the printer can read it.
✅ The "Upgrade" trick to force the downgrade.
✅ How to recalibrate and get back to printing fast.
You don't need Creality Print for this—just a USB drive and a few minutes.
Watch the fix here:
