I’m having a similar issue. Fully assembled my new Ender 3v2. Following the instructions, I tried auto homing. The print head repositions to what looks like the spot that would be 0,0 on an x y coordinate and then the display is stuck at “Auto homing...Please don’t other operation” and the display stays there. I checked the voltage (115) and the x/y cable. Firmware is 1.0.2. I have not opened the cover to see if the motherboard is wired correctly.

Please advise.
