great guide! , bluetooth now is working 100%…..good signal range and music not skipping to wireless speakers.
Mine, was difficult to reassemble. I fix the original cable, cutting the damaged part and drilling a hole in the original cable grommet with a dremel rotary tool then passing through the cable and solder it to the board.
It was easier than I thougth, my iMac was acting weird with a dead Pram battery, great guide!!...thanks a lot iFixit!
