Some netizens said that they bought a iphone12 from a friend, saying that it was for his own use and that the price was relatively cheap. However, after checking the machine, he discovered that it had a fatal flaw, that is, the hidden ID.
What is a hidden ID? It means that someone logged in an Apple ID on this device, but did not log out when reselling it to someone else. In this case, if you don't know the account password, you can't log in to other accounts unless you go through some special methods. By bypassing the ID, the previous ID will be temporarily hidden, allowing you to log in with other IDs.
Then why is bypassing the ID temporary? Because once the phone is restored or flashed, the original ID will be revealed and it can no longer be activated and used. How does
know if this is a hidden ID?
The first step is to log out of the ID account and turn off the "Find My iPhone" function.
The second step is to find the serial number and do a gsx machine inspection.
If after exiting the ID, the machine inspection result still shows that the activation lock is on, then this is a hidden ID machine.
