When you flash multiple iDevices using 3uTools, 3uTools will bind the USB port automatically after you connect an iDevice to PC using the USB cable, which means when an iDevice is connected to the same USB port, it will be displayed in a fixed row position in the list.

Sorry to know that, so you can directly Easy Flash on 3uTools, but do not select the option 'Retain User's Data While Flashing', then you will lose the data, and then you just need to activate your device. Error -1 on 3uTools may be caused by USB cable connection, network and baseband. Try to change the usb cable, confirm the network connection. If error still exists, you would need to change the baseband. Was this answer helpful?

Why do I need to unbind port?

If you want to adjust a port’s row position in the list, you may click “Unbind Port” and then reconnect the iDevice.

If a port is unbound, it won’t be displayed in the list when it is no iDevice connected to; if you unplug iDevice while a port is bound, this USB port will continue to be displayed in the list.
