Part 1. Erase All Data on iPhone

Step 1. Free download and install Aiseesoft FoneEraser on your computer. Then launch the program. Enter your email address and the registration code to activate the program if you want to enjoy full functions.

Step 2. Use a USB cable to connect your iOS device to computer. Then unlock your device. You may see a popup asking if you want to trust this computer. Just tap on the Trust option and enter your passcode to trust the computer.

Note: If your computer doesn’t recognize your iPhone/iPad/iPod, you need to check whether you have installed the latest iTunes. If not, you can update iTunes to the latest version. You can also choose to install the software from Apple’s official website.

Step 3. There will be three erasing levels for you to choose: Low, Middle and High. The Low security level enables you to quickly erase all the data on your device, which is almost twice faster than other security levels. The Middle level will overwrite the erased data entirely to make sure the data cannot be recovered. As for the High security level, it is based on the U.S.DoD 5220.22-M wiping standard that can erase your private data like password and bank records.

Note: This software will wipe out all iOS devices content and settings at a time without selective options. So, you'd better back up your important data before this process.

Step 4. After choosing erasing level, you can click the Start button to erase your iPhone, iPad or iPod data. Please enter 0000 to confirm the erasing. Then click Erase to erase all data on your device. Now, you have completed the whole process of erasing everything on your iOS device.
