Do a factory reset to return HTC Status to its original state before the first time you turned it on.
If you’re passing HTC Status on to someone else or HTC Status has a persistent problem that cannot be solved, you can perform a factory reset (also called a hard reset). Factory reset is not a step to be taken lightly. It’ll permanently delete all your data and customized settings, and will remove any applications you’ve downloaded and installed. Be sure to back up any data and files you want to keep before you do a factory reset.
