i got a problem with my new Xperia SP.
I had to encrypt my Phone because After the Update and the reboot the Phone isn't able to decrypt the System Data's and stucks in a Bootloop.
I'm able to fix it by myself?
Our have i send it back?
Please help me. 
Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.
I suggest that you try to reinstall the phone software using Update Service..
If the issue should still remain I think that this needs to be examined and fixed at a repair center. For more information about how to submit your phone for repair and where, contact your local support team.
