Resetting HTC One (Hard reset)
If HTC One has a persistent problem that cannot be solved, you can perform a factory reset (also called a hard reset or master reset). A factory reset reverts the phone back to its initial state the state before you turned on the phone for the first time.
The following will be removed from the phone when you do a factory reset:
- Your Google Account
- All accounts you’ve added in Settings > Accounts & sync and the data associated with these accounts
- Personal data that you’ve created or synced to the phone such as your profile, contacts, messages, email, calendar events, and more System and application data and settings
- Downloaded apps
Files such as your music, photos, videos, and documents can also be deleted from the storage, if you chose to do so.
Be sure to back up any data and files you want to keep before you do a factory reset.
Note
A factory reset may not permanently erase all data from your phone, including personal information.
Performing a factory reset from settings
- Go to Settings, and then tap Backup & reset.
- Tap Reset phone.
- If you want to delete media, documents, and other data from the phone storage, select Erase all data. To also delete media and other data from your storage card, select Erase SD card.
- Tap OK.
