My iPhone 6 was disabled

Hi,

If you can’t remember your passcode, you'll need to erase your iPhone, which deletes your data and settings, including the passcode.

If you've backed up your iPhone, you can restore your data and settings after restoring your iPhone. If you didn't back up your iPhone before forgetting your passcode, you won't be able to save the data on your iPhone.
