Upgrading to bluetooth 4.0

Mon problème

I removed the bluetooth chip to see if it was bad, it was so I am upgrading to bluetooth 4.0 so I can use airdrop and airplay. So far it is working well. I highly recommend doing this so you can use Apple TV or file sharing between computers.

Mon conseil

For the screws I use old medicine containers with lids, number them before hand, and go step-by-step removing screws and small items. Then reverse the order to assemble.
