There is no longer a DoulCi download link, so what can you do to overcome this challenge?
The problem is DoulCi Activator, the primary solution for this, officially shut down in 2014. On the other hand, there are ways to bypass this problem, so you don't need to worry. Hence, you might encounter difficulties if the previous owner didn't handle the lock before selling it to you. Did you purchase a second-hand iPhone but can't access it because of the Activation Lock? This lock is a feature on iPhone that is developed to make sure no one else can use the device besides the original owner.
