Stay black and no uptabable after firmware update
I was an happy owner of a Creality Ender-3 V2 with a 4.2.2 board inside.
I updated the printer two day's ago and the process stuck i presume as the screen stay black and never go back to the Creality logo / panel as i can see on multiple youtube video.
I tried to find a way to do some repair / bootloader initialisation with my Arduino card but cannot find any way to connect it with the card as pinout look to be different from other boards i can find information over.
My card is a 4.2.2.
Is there anything i can do from your own return on this kind of problem ?
Thank you for your kind feedback.
