How do I unlock xperia SP with software - Sony Xperia SP LTE C5303 Unlocked White

keep entering wot you think it is till it locks up then call your airtime provider for a puk code to reset it, or do a factory reset, try 0000 or 1234 as defaults first.

Hi. Thanks for using fixya. This problem can be solved by reloading the software with flashtool or sony companion. There is no hard reset for Sony like other androids.
select your firmware here. and also Flashtool

If you want straight forward with step by step, download the Pc companion:

When the phone is unlocked, you only have to give in the pin that belongs to the sim you did put in.
If the phone is not unlocked, you won't be able to unlock it, because only the first owner with his sim, can ask for the unlock code. Lots of providers want you to continue a contract for a certain period, even when the original contract had finished. Go back to the person you bought the phone and insist he helps you with the unlocking.

Try clearing defaults in the apps settings.
