How to unlock my Sony Xperia C3 Dal without the unlock pin?

[bianca18]

Hey!
I happened to forget the unlock pin of my phone, which is a Sony Xperia C3 Dual.
Sony says that i should factory restore and i will lose all my data in that process which i cannot afford to
please help me in the process, anything will do as long as i dont lose any data.

Thanks a lot.

Bring the phone to your carrier, with photo ID proving that the account the phone is on is yours (or bring the account owner with you) - and they can remove the PIN lock and return the phone to Swipe.
