UM 2+ only blackscreen after firmware update

Posted · UM 2+ only blackscreen after firmware update



after i accidentally uploaded a firmware with bootloader to my um 2+ and stopped this update at the half the printer cant connect to Cura.

Also i cannot write a new firmware via arduino...than i get avrdude: stk500v2_getsync(): timeout communicating with programmer

But i can the that the bootloader is some kind of working because i can see that its connected to com6.


Any idea, how i can fix that ?
