Help finding the right part for bluetooth board replacement

I have a mid 2012 unibody macbook pro, 13". Model A 1278, model identifier MacBookPro9,2 2.5Ghz Intel core i5. And it says Mid 2012 when I display system info. So I am as sure of the model as I can be, but of course, if someone has a doubt or something I should check to be sure, fire away and ask.

I need to replace the bluetooth board because of low signal.

I checked the repair guides and the parts I needed to order were listed on this page:

MacBook Pro 13" Unibody Mid 2012 AirPort/Bluetooth Board Replacement

The guide clearly shows a two part bluetooth board. A bracket and the electronics on a separate, smaller board. I ordered both and received them a couple of days ago. Today I decided it was time to do the repair and I proceeded according to instructions. All went well until near the end when I was surprised to see that my macbook has a single piece bluetooth board. I.e. the bracket and the electronics are in one assembly. no screws to take it apart. just one assembly.

I would have tried replacing the single piece board with the bracket and electronics pieces that I received, but I would have needed 3 screws which I don't have. And they are tiny things that are hard to find at your local hardware store.

One more piece of relevant info. My computer was refurbished by Apple. So it's possible they "upgraded" the bluetooth board when the refurbished, which may explain the discrepancy between the guide and what is actually in my macbook.

Anyway, some questions:

1) can I use the bracket and electronics I received from ifixit and if so, where can I order the 3 screws I would need?

2) If I can't use them, can anyone tell me which parts I should be using? (and which guide i.e. what model macbook pro would lead me to the right instructions)

3) The instructions have you pull off the tape over the bluetooth connector, but no replacement tape comes with the parts. I managed to get the tape back on when I reassembled the macbook (using the original parts), but I don't think it will survive another removal. What type of tape do I need to get to replace the tape I'm taking off?

I think that's about it, if you need more info, ask away, I'll try to answer to the best of my ability.

many thanks.

Hi there!

Thanks for reaching out to iFixit customer service as well. We've contacted you via email to try to sort this out.

Regarding the tape, you can see on this step of the guide that it is EMI tape. We don't have that for sale on our website, but I can absolutely check our stock of brackets to see if they are supposed to come with it, in case for some reason the one you ordered was missing the tape but should have had it.

Again, we'll speak more via email and exchange some pictures and get this squared away. Thanks for your patience!

Annette -- many thanks for reaching out. I have had good experiences with iFixit in the past and with your help I think this will get resolved and will be another good experience.

I think Apple may have thrown us a curve on this one -- remember my macbook was bought in 2014 as a refurbished unit, so Apple may have switched from the original part.

of course the other possibility is that I just couldn't see the screws (not kidding here, you have no idea how many times I lose things that are in plain view).

But I really don't think iFixit is the source of the problem. that said, I am hoping you are the source of the solution!!!

I'll contact directly on email (thanks for that) and will post more when this is resolved.

I followed up with Annette and the problem is resolved.

the issue was operator error (me). I didn't remove the tape from the bottom of the board so I didn't see the screws.

John, thanks for trying. But this is the same part that I already ordered and it is NOT the same as what is in my macbook. I ordered that part, together with the bracket already. I received them and they DO NOT match what is inside my macbook.

by

also, I cannot even try to install them because to install them I would need the 3 screws that hold them together. Normally one would use the screws from the board/bracket combination that is in the macbook, but I cannot do that because the bluetooth inside my macbook is one solid piece that cannot be taken apart and has no screws.
