Mine not soldered.

Adhesive under the left cable made it hard for me to remove it. The right one came out very easy.

i broke off all the connectors to the logic board any fix for this ?

be gentle - lever under each edge of the connector - you may have to do one side then the other , but the connectors come out easily enough

Key here is to go EXTREMELY slow and gentle. The speaker connector in left photo has no release lever(in case you were wondering) I used a tweezer to hold very outside edge down while massaging cable side from underneath with spooner. Gentle rocking and it finally came out properly!

These instructions are completely inadequate. For anyone who hasn’t done this before, there has to be some image of whatever it is that releases the cables. “Pry the left speaker connector up” without showing the release is just telling me how to turn my computer into junk. . . Which I just did. It’s twelve years old and fully backed up, so I was prepared for this, but I am very disappointed in these instructions. They’ve been bad from the start.

Es wäre besser, wenn man den Ausbau des rechten Lautsprecherkabels besser heraushebt! Ich habe das leider überlesen und den Connector zerstört. Aber ich habe es doch irgendwie geschafft, das der Lautsprecher funktioniert!

Pay attention that there are 2 connectors of speakers! Otherwise, you will realise in step 32 (like I did) that you forgot one of them ;).

Despite being extremely careful, both of these connectors broke off from their position on the logic board. It seems like they were soldered on rather than being just a push fit.

following these instructions exactly removed the entire socket from the board. This needs much more detailed instructions and pictures on how to accomplish this and how the connector is put together. the wide view here is grossly inadequate. This needs a much bigger warning to slide the cable away from the connector as any prying will destroy it. The socket came up and took the pads with it, so there's no soldering it back on. guess I'll just have to go without one audio channel in the onboard speakers

well, i managed to do it without screwing the cable, you've actually got to hold the cables at the very base of their connection to the board and gently pull the all together up, not to the side.

Use the retaining flap to pull the ribbon cable back into the socket.

This keyboard ribbon is so thin. It is like thinner than X-ray film. I was afraid to remove the ribbon from the socket. So, I skipped this step and follow other steps till ‘Step 30’. I didn't remove the logic board as shown in Step 31 and 32. Instead, I removed DC board screws and then DC board from the hole. The cable from the DC board connected at bottom corner of the logic board. I hold the MacBook Pro vertically and lift the logic board slightly and removed the DC board ‘plug’ from the socket. Next, I plugged in the new DC board and followed this procedure in reverse order ( from Step 30 to Step 1). Everything went fine. Important Note: When lifting logic board, please do it carefully and very slowly. Don’t be hurry and don’t break anything. Use magnifying glass and Magnifier in your iPhone to see the tiny parts big and clearly, before removing them.

Rather than pushing with the Spudger, I found it much easier to use the tape to pull directly back on the connector.

I just used tweezers.

Looks like it had a sticky patch fixing it near the edge of the board - this would make it unwilling to come out of the socket. The patch looks to be the width of the cable and square, so probably pushing a thin something (plastic) under the cable up to the edge of the board would unstick it.

green indicator: raised head screw is the one you removed the rubber cap from in prior step. (I removed – and then replaced — a different screw in this step. Revisited it with more daylight and saw my error.)

Yes heed everyone’s warning. I had to remove the entire logic board TWICE because i forgot to pull out the antennae and the backlit keyboard plug.

Yes, be very careful before screwing things down. I also forgot the backlight and the display cables. Had the cover for the display cable out, but not the actual cable. I was able to use tweezers to fish the cables out after removing the screws but without removing the whole board.

My logic board was stuck under the battery PCB, on the top right side of the battery PCB, when viewed like in the first picture.

I suggest removing the two screws from step 35 holding the PCB down for a little more wiggle room before attempting to remove the logic board.

I had to go back cause I couldn’t figure out where the logic board connector into (under the board). Funny enough i assembled it and it worked though the night and didn’t come on again. Had to go through the whole process b4 i figured it out. Definitely a good idea to at least breeze through all the images

reassembly: so far the hardest step. After getting all the connectors above board, I still couldn’t quite line up the screw holes. It finally turned out that the board was being prevented from being in its full leftward position because the edge of a flange at the top of the USB port was directly positioned against the edge of a flange on the case. I used my thumbnail to press down on the port’s flange so that it slid under the case flange, allowing the board to shift left another half-millimeter and make everything finally line up.

For me, this step was the most hard part when reassemble. Because it is easy to forget or hard to reconnect MagSafe 2 connector properly. I had to give in to professionals just to find out i couldn’t plug this MagSafe 2 connector properly. because of it’s limited angle and i only have 2 hands to do the job while board is lifted.

unscrewing the mag safe as max suggests is a great suggestion. Easier and you can clean the connector.

It is not necessary to remove the logic board for this. I did this process without removing the logic board and the 30 steps required to disconnect, remove and reconnect it. It was much easier. Not sure why iFixit insists on removing the logic board: its presence does not block removal of the battery.

Why do you need to remove the entire logic board??? Seems like if you detach the appropriate cables, remove the speakers, that that should be enough. Removing the entire board doesn’t seem necessary - what am I missing?

Same question here. What’s the reason behind removing entire logic board?

From what i gather, logic board removal facilitates de-adhering the ex-battery units, as the solvent can damage the speakers.

I had the hardest time removing the MagSafe 2 connector clip and ended up removing the two screws to dislodge the entire connector.
