How do you reset an iPad that is using an apple id that is no longer working, i changed my id and never logged out of it on my iPad before the change

Question

so i changed my apple id since it was attached to an email i don't use and forgot to log out of my iPad before doing so. i don't use it often so this was probably two months ago and now i notice the old apple id that always will come up invalid user name or password but can't change the actual id to the correct one so have no idea what to do next

Answer 1

To change the iCloud ID you have to go to Settings>iCloud, tap Delete Account, provide the password for the old ID when prompted to turn off Find My iDevice, then sign back in with the ID you wish to use.  When you do this you may find that the password for your old ID isn't accepted.  If this should happen, and if your old ID is an earlier version of your current ID, you need to temporarily recreate your old ID by going to https://appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID.  Click edit next to the primary email account, change it back to your old email address and save the change.  Then edit the name of the account to change it back to your old email address.  You can now use your current password to turn off Find My iDevice on your device, even though it prompts you for the password for your old account ID. Then save any photo stream photos that you wish to keep to your camera roll.  When finished go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud).  Next, go back to https://appleid.apple.com and change your primary email address and iCloud ID name back to the way it was.  Now you can go to Settings>iCloud and sign in with your current iCloud ID and password.
