You're missing 2 essential steps - how to lift the fan outlet over the plastic tabs holding it in and how to disconnect the screen from the motherboard. This tutorial has been republished on so many sites, I can't find anything else. I eventually just snapped off the tabs with pliers, but obviously I need to have an intact screen cable. Without removing that cable from the motherboard, you can't get enough space to then pull the motherboard out from where it's connected on the right side. Very disappointing tutorial.
By looking at the photos it looks like the display cable is just North of the fan looking at the motherboard from the top of the laptop. It has the pull tab. I think the cable pulls out of the motherboard straight up. When I did it, I either did it by hand or very carefully with needle nose pliers. I'm not sure where your difficulty occurred? It doesn't have any specific lock. You pull off gently and to reconnect you push on gently with even pressure on both sides
The other ribbon cables on this and other laptops either use a flip-up style lock or push in-out style lock.
Within a few weeks I should be able to go to my friend's house where I have a broken down U47 and see how the connector works for certain.
Side note, in no photos or steps in this tutorial do I see how or where to disconnect the Wi-Fi antenna..
