Hi there!
I have been looking for ways to permanently wipe out/ zero out all data stored on my iPhone 5. I know that there used to be an app called iErase, which took care of this problem very nicely. However, it seems to have been taken down from the App Store.
I was wondering if there might be any other ways for me to zero out my iPhone's storage.
Appreciate the help!
iPhone 5, iOS 9.3.5
Yes, restore the device to factory. Use iTunes on your Mac or PC to restore your iPhone, iPad, or iPod to factory settings - Apple Support
Settings > General > Reset > Erase All Content and Settings
The "restore to factory" option does not overwrite stored data, but merely deletes the operating system's decryption key. Do you know of any way to permanently overwrite stored data instead?
Restore to factory wipes the device and installs a new copy of the operating system. I'm not aware of anything that writes over the device again. The data is encrypted to start with, so even if someone was able to recover it, it would not be readable.
The iPhone User Guide explains that Settings > General > Reset > Erase All Content and Settings does indeed erase the iPhone.
