If you want to erase all of the data and settings on an iPad, you can restore the device to its factory specifications. This is a useful option if you are giving the iPad to someone else or if you just want to make a clean start for yourself. There are two ways to restore the iPad; with or without iTunes. If you restore it with iTunes, a backup will be made of your files and apps. Once it is reset, you can restore your files and apps from the backup.
Restoring to Factory Condition With iTunes
Open iTunes on your computer. Make sure you have the most recent version of the software. Then connect the iPad to the computer.
Select the iPad in iTunes. It is located on the sidebar under "Devices."
Click "Restore" in the "Summary" window.
Click "Back Up." When the backup is completed, a pop-up window will appear.
Click "Restore" in the pop-up window. When the iPad is restored to its factory settings, a pop-up window will inform you that the iPad will be restarted. Click "OK."
Complete the restore process by loading a backup to the iPad or opting to "Set up as a new iPad." If you select the backup option, you can select which of your recent backups you would like to install from the pop-up window.
Restoring to Factory Condition Without iTunes
Turn on the iPad. Select "Settings," "General," then "Reset."
Select "Erase All Content and Settings." All the data and settings on the iPad will be erased in about one minute.
Select either to restore the iPad from a backup or to use it as a new device the next time you connect it to the computer using iTunes.
