CR-200b printer firmware cannot be updated.
Since my printer was causing problems and the print bed did not stay in the home position, I was advised to update the firmware. Unfortunately, that seems to have gone wrong because the printer currently only shows a black screen and when I try to update the firmware of the display, it also fails every time.
but did it exactly as shown in this video. What could I have done wrong.! ![0_1648851951467_20220331215622.jpg](Uploading 6%)
