Wifi & Bluetooth not available after upgrading keyboard
I have recently upgraded my keyboard by doing the following this tutorial: Upgrading your 2.0Ghz 13" Aluminum Unibody Macbook to a Backlit keyboard
The new keyboard is well installed, but I have now the following messages regarding the wifi and the bluetooth: "Wi-Fi: No hardware installed"; "Bluetooth Not Available".
Did I damage one specific cable? Which one? Or did I damage the airport card? Or it is something else?
I have also tried to reset NVRAM and SMC but it did not work.
Thank you in advance,
Is this a good question?
