I've the same issue with my Halot One as described in this older post:
Halot Sky OTA Firmware Update Broke My Printer
I've started a regular OTA firmware update as I've done already quite some times before without issues. This time the printer didn't start after the update. Only thing to see is the "Creality Ninja", and not even the animation, only a static image. I've also tried to connect the printer to Phoenix Suit but the printer did not even establish an USB connection at all. No menu, no remote access via USB, I don't know what else I can try to bring it back to live. The old topic didn't get any answers so my hopes are not that big. But at least I need to try before I dump the printer...
