Deleted Apple ID

Hello Nekriis.

Thank you for using Apple Support Communities and for sharing these details with us. If you have already successfully deleted your Apple ID, you won't be able to sign out of iCloud to disable Activation Lock on your devices. Apple will not be able to help reopen or reactive your account after it's been deleted. You can review more details int he following resource below:

How to delete your Apple ID account - Apple Support

Under "Before you request deletion of your Apple ID", it states the following information: "After your account is deleted, you can't sign out of iCloud or turn off Find My iPhone Activation Lock on your devices. If you forget to sign out, you might not be able to use your device when your account is deleted."

We hope this information is useful. Best of luck.
