Hi Matthias,

I open again this topic

I have a MK2N N°3444 with a blank screen

It is an uniform blank screen which turn off after few minutes
I tried to hard reset it with a magnet : the screen was blinking but stay blank

It is readable from OSTCtools
I could not upgrade it from 2.21 to 2.7 with bootloader v1 but I did it successfully with bootloader V2
So now it got a 2.7 firmware

Any magic procedure ?


Regards,

Xavier

If this error was before your update it's more likely a hardware issue -> info@heinrichsweikamp.com
