Turning on my bluetooth without a readbale screen

Hello! The same thing happened to me, but through the Nokia website, by miracle I found a demo on turning on Bluetooth on this phone!!
Press the menu button (central button).
Go Left (you will get to settings). Press the central button.
Go down 6 times (you will get to connectivity). Press the central button.
Press the central button again (you will have clicked on "bluetooth")
Go down once.
Press the central button.

Now bluetooth is on.

Make sure bluetooth is on on your mac.
You need to open "iSync" on mac to get your contacts. Open "iSync" from the Applications folder on your mac.
Select from the top-bar menu "device" then "add device..."
A new window will open which will be scanning for new devices.
If the light on your phone switches on again, it will be asking you whether you want to connect to the computer. Press the central button to accept.
When the computer finds the phone, double-click on it. Press "sync devices" on the original window of "iSync".
Your phone's light might switch on again: press the central button to accept.

When I tried this it needed some trial and error but in the end it worked! Mostly it was about the phone probably asking me to confirm that I wanted to connect, and me not knowing!

Best of luck, anyhow...
