my phone is disabled

Once your iPhone is plugged into iTunes according to the referenced article, you'll need to follow the prompts to "Restore" the iPhone. You should have the same pop-up windows that appear in the article in order to factory reset the device.

Hello magic833,

Thanks for reaching out to the Apple Support Communities.

You missed a step. You'll first need to put the iPhone into recovery mode before iTunes on the computer recognizes it.

Please follow the steps in If you forgot the passcode on your iPhone, or your iPhone is disabled - Apple Support to put your iPhone into recovery mode and reset to factory settings.
