Erasing old iPhone after Apple ID has been changed
My daughter has an old iPhone 5, which I want to factory reset for her, so it can be used as a child's phone. However, it can't be erased without the Apple ID and password. But since it was last used, she changed her ID. At the erasure screen, there is no option to change the ID, only to enter the password for the old ID. We have the old password, but before trying it, I want to be sure this won't cause a problem with her current ID / iCloud account. The old phone has been removed from the device list on the current account. Does anyone know:
- Will Apple recognise the old ID as related to the current iCloud account with the new ID?
- If it will, does signing in on the old iPhone, in order to erase it, cause it to (eg) try to back up?
- If it will not, is there any way to erase the old phone? Other than running over it.
