Wifi & Bluetooth not available after upgrading keyboard
I have recently upgraded my keyboard by doing the following this tutorial: Upgrading your 2.0 GHz 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,
Es esta una buena pregunta?
