Ender 3v2 bltouch firmware upgrade crased
I have upgrade mine Ender with a bltouch v3.1 special set for the v2
I take the firmware for the 4.2.2 MB (is in it) for BL without adapterprint and put the bin file on the sd card
After powering up the screen goes black (is ok ) but didnot come up again , now he does nothing
Can someone help me to get him back alive ?
