If you sold it for spares or repair and the buyer has now got it fixed you are in a awkward position.
In order to complete the repair he needs to have full access and this would have been his expectation when he purchased.
The fact the phone may contain sensitive info is something you should have considered before listing.
You cannot reasonably expect the buyer to return a working phone to you without some payment to him for his time and any parts cost
