已经越狱的设备，如果存在激活锁，即已登录AppleID，且开启查找我的iPhone功能，可以通过以下命令行绕过激活锁。
Devices that have been jailbroken and have an activation lock, i.e., are logged into AppleID and Find My iPhone turned on, can bypass the activation lock with the following command line.
1 | mv /Applications/Setup.app /Applications/Setup.app.bak |
执行完毕这三条命令后，设备会重新进入白苹果界面，随后正常进入系统。
此方法仅仅是阻止设备激活锁的运行，并非取消激活锁或登出对应的AppleID，当设备升级iOS或刷机时，会重新出现激活锁，因此请务必慎重升级与刷机。
This method only prevents the device activation lock from running, not cancels the activation lock or logs out the corresponding AppleID. When the device is upgraded to iOS or flashed, the activation lock will reappear, so please make sure to upgrade and flash carefully.
