I’m seeing people with 2011 and 2012 ribbon cable issues. Anyone here having issues with a mid 2010 13” MBP. Mine started acting up and I heard several mentions in other forums that the issue is likely a bad ribbon cable. I can’t enter ADT. I get an error code -3403D.

I also was having trouble with an SSD installing and updating on the initial boot but failing to boot thereafter and instead sending my to a page to save the installer log..

It booted my regular non SSD fine. This sounds the signs of ribbon cable failure I read about but does the 2010 have the same issues as the 2011 and 2012 as far as replacing the cable goes?

Do I also need to insulate the ribbon from the case?
