How to Reset an iPhone 4S With a Passcode
By Avery Martin
The iPhone 4S provides security features that help to protect your data in case your iPhone gets lost or stolen. After entering an incorrect password six times, your iPhone disables itself to prevent unauthorized access to your device. Provided you previously synced your iPhone with iTunes, you can simply connect the device to your computer and restore access to your iPhone using iTunes. If you can't access the iTunes library you use to sync content to your iPhone, you can restore your iPhone and completely reset your device. Restoring your iPhone removes the password, but it also deletes all of the stored content and settings.
Restore Device Previously Synced With iTunes
Connect your iPhone to your computer and launch iTunes if it doesn't open automatically.
Right-click your iPhone in the Device column and select "Backup." If the sidebar doesn't display, click the "iPhone" button on the iTunes menu bar. Select the "File" menu, click "Devices" and choose "Back Up."
Click the "Restore" button and choose your latest backup when prompted.
Restore Without Accessing Previously Synced iTunes Library
Press and hold the "Sleep/Wake" button until the red slider displays.
Swipe the slider from left to right and wait for your iPhone to shut off.
Press and hold the "Home" button while connecting your iPhone to your computer. Release the "Home" button when the Connect to iTunes screen displays.
Click "OK" and select "Restore" to restore your device.
You can reset your iPhone using a recent iCloud backup or by restoring your iPhone and connecting it to any iTunes library. However, you may lose data if a current backup isn't available.
