Fried my V.4.2.7 Board
hope someone could help.
Got V427 board to update my Ender 3 V1.
Did the cableing according many, basically similar How-tos but must have done something wrong.
Switching it on the first time was credited with a flash and smoke.!
Power cables had black to the rightside.
The 2 red ones on the right plugs I might have mixed up.
See Pics for Cables and localization of burned spot.

Since I wand to reinstall the old bord until I got a new one, and do not want to have that happen again at both of them I need the actual cause of it.
