Apple ID not active - Request Denied- Authentication Block - Cannot Be Removed

Lmao, I just had the same problem after the iOS 18 update. Calling support is useless—they can’t even find your account because I think it’s deleted. What I did was connect my phone to a MacBook in recovery mode and restored it (not updated). You need to know your passcode or you’ll get locked out, as it will ask for the activation lock (iCloud account, and since it doesn’t exist, you can’t log in). After that, connect your phone to an existing Apple ID that works, and voilà! I think this is a new, very annoying bug that should not happen—it literally turns your device into a brick

It’s not a bug. Apple is deactivating and locking the account because they determined the Apple ID has broken Apple‘s terms and conditions of use. In certain circumstances you can request it, be reactivated, but at a certain point, they will deny use of the Apple ID ever again.

If you are using the iCloud Find My security feature That will mean you’ll need to submit proof of ownership to request Apple remove the deactivated Apple ID from the device on their end. If you use recovery mode to restore an iOS device that will cause activation lock to appear as intended because Find My is not off yet.

First of all, there’s conflicting information in your post. Your post says “New iPad” which brings to mind a brand new, factory sealed iPad in an original box from an Apple Store or Authorized Apple Retailer. But your profile lists a ninth generation iPad, which was discontinued by Apple more than four months ago.

Your post suggests some omitted facts regarding the origin of this iPad.

I don't think so. The OP said that he created a new account, so I don't think he would violate the terms in just one day. The same thing happened to me — I had a brand new account and still got the same issue as he did.
