I had a V4.2.2 board years ago. The SD firmware update process (even with Marlin firmware) was a total coin flip. The board doesn’t change the filename so you never know if it actually flashed. If it won’t connect you don’t know if it is bad firmware or a bad flash.

Review the instructions at Creality for updating firmware. The process is exactly the same no matter what .bin file you are trying to flash.

Read the threads for tips and tricks.
