If your iPhone fails to unlock after implementing the solutions above, then it’s high time you consider unlocking the device via a third-party tool or iTunes. Both approaches are described in the next section of this post:

Conclusion

When your iPhone passcode changes by itself, the solutions suggested in this post should help you resolve it.

However, Passixer iPhone Unlocker is our most preferred. The software removes screen passcode without so many conditions to fulfil while its success rate are ensured.
