Help Replace headset jack/left loudspeaker

[mikep1355]

I have to replace the headset jack in my tab pro 10.1 . I managed to remove the back cover although the instructions I watched failed to mention you must start from the front so I broke a tab. Now I'm in and have removed the screw holding the jack and loudspeaker module I still cannot get to the connections along the edge. It looks like the white plastic border must be removed and I can't find any mention of this on the videos online . Anyone can help me here ?
