Things look different at a late 2011 MBP. Here the camera and Bluetooth cable are attached to a black plastic frame. This frame can be flipped up from the top side of the optical drive after releasing 2 Philips screws (one situated at the top right corner of the frame, the other one at the metal bracket leadig to the back side of the upper case.
Please note that for replacing the keyboard (as I am intending to do), it does not seem neccessary to disconnect the cables from the plastic frame, in order to fully remove it from the upper case.
The same applies to the late 2011 model.
On my late 2011 MBP there are two connectors at this place: One big connector like the silver one shown on the fotos (but in my case it is black), and the tiny one as discribed in the comment from anon 10/14/2017). In contrast to the fotos, this tiny connector is on the opposite side of the big one, on the edge close to the right fan. To disconnect this connector, follow the instructions from anon 10/14/2017.
The cable going to the big connector is in my case a wide black ribbon cable running diagonically over the optical drive. To remove the connector of this cable from the socket, pry it upwards carefully with your fingernails or a spudger.
Als ich das Flachbandkabel auf der rechten Seite sah, hab ich mich auch gefragt, ob die das mit nach Links klappen ernst meinen, und das „Buch“ lieber auf japanische Art nach rechts aufgeklappt. Das sollte dringend in der Anleitung korrigiert werden!
Unfortunately I encountered the same problem as matbub. A close plastic frame around the battery on the circuit board prevented me from introducing any tool under the battery, and the battery was sticking so firmly to the circuit board that it was impossible to lift even a single corner. Heating with my hair dryer did not help as well. I have changed a lot of batteries in other phones so far, but finally I had to accept not being able to change this one. Despite all the obstacles that I managed to pass through before. Bad job, Samsung!
After removing the screws, you can lift up the upper part containing the switches, the LEDs and the cover of the USB port, hence revealing the view on the battery and the delicate ribbon cable as shown above.
However, the USB plug and its daughterboard are still attached to the motherboard. In order to replace the USB plug, we would need further instructions on how to remove ist. I do not understand why the guide ends at this point. Without this information, the guide seems pretty useless to me.
Additionally, In my case, the USB plug, its daughterboard and the ribbon cables are fixed to the main compartment with some sort of black as well as yellow glue. Any idea how to remove that, without further damage?
ACHTUNG: Dazu muss man zum einen auf der Lautsprecherseite an beiden Enden jeweils 2 Schrauben lösen (siehe “Step 3”, warum auch immer einem das erst in einem Folgeschritt gezeigt wird), zum anderen auf der anderen Seite (neben den Bedienelementen) jeweils 3 Schrauben auf beiden Seiten. Versäumt man letzteres (wie es mir ergangen ist, weil in der Anleitung ja nichts davon stand), geht der äußere Rahmen auch ab, allerdings brachen dann die dünnen Plastikösen, in denen die 6 Schrauben steckten, ab! Was für den späteren Zusammenbau und die Stabilität des Gehäuses alles andere als günstig wäre (und bei mir so ist ;-(
I fully agree. I was very content with all the repair guides I found on ifixit so far, but this guide is really poor. Missing steps, wrong order, and it does not even lead to the solution that it pretends to deliver. I am sorry, if the authors are not willing to improve and to complete this guide, it should better be removed, in order to be replaced by something more useful.
