Resetting HTC One max (Hard reset)
If HTC One max 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 will also be deleted if you
select the Erase all data option.
Be sure to back up any data and files you want to keep before you do a factory reset.
A factory reset may not permanently erase all data from your phone, including
personal information.
Performing a factory reset from settings
1. Go to Settings, and then tap Backup & reset.
2. Tap Reset phone.
3. If you also want to delete media and other data on HTC One max, select Erase
all data.
To delete media and other data on your storage card, tap Erase SD card.
4. Tap OK.
