If you change your bluetooth card, its MAC address will change. Since pairing is done by MAC, you will need to re-pair all devices.

My Wifi failed, "no hardware found", but the Bluetooth still worked. I replaced the board, but still no dice. Turns out it was the cable. Lesson learned: try the cheaper part first! Not a total loss, now I have Bluetooth 4.

Hello,

I was able to complete this repair in less than 40 minutes, thanks to the author and his easy-to-follow guide!

Regarding Step 10 - I found it easier to use a Phillips #000 screwdriver (instead of the recommended #00 size) for the two “orange” 3.1 mm Phillips screws, as it did not slide off the tiny screw heads like the larger-sized screwdriver would.

This is an amazingly succinct and clear at of instructions! My Hat is of to you!

I discovered that the flat wifi cable was not properly plugged in, so I plugged it back in and went no further! Yea it worked!

I added this note already in step 7, but want to make more visible for those that might encounter a broken cable:

Actually, on my repair attempt, one antenna cable broke (on the image the bottom right one in the red square in #7), I’m not sure whether it broke already before or was morbid somehow. Fact is: suddenly I had this cable in my fingers, and was sure I completely broke the macbook and need to find a new display now.

But as it turned out: the Mac is still fully working, including WIFI, BT, Camera etc. So apart from my huge relief, I want to address that these cables may break easily at their connection with the display. And that one antenna might be not mandatory for WIFI to work.
