If you can't complete any of these steps, if you're still prompted for a passcode, or if you need any other assistance, contact Apple Support.

Here is the Factory Reset: Restore your iPhone, iPad, or iPod to factory settings - Apple Support

If that sequence is not working for you, please indicate which step is failing, and any messages or diagnostics shown.

The passcode reset sequence is relatively similar: If you forgot your iPhone passcode - Apple Support
