So, we temprooted your phone, but we weren't able to permaroot it for some reason.
Please post on XDA with your phone model, carrier, and SW version in the PurpleDrake thread and someone will take a look.
Your phone has been rebooted back to normal system mode, no changes have been made. Thanks for trying!
