How to disable the Lost mode on a device which is not network-connected?

• If possible, insert a SIM card that does not have a PIN code set.
• Alternatively, you can connect the device to a network using an Ethernet adapter with Lightning Connector. In order for this method to work, "Allow pairing" must have been allowed when the device was enrolled in LogMeIn Resolve MDM through Apple Business Manager.
• Restore or erase the device using Apple Configurator:

  • Connect your iOS device to the Mac through USB and launch Apple Configurator.
  • Go to Actions > Restore or Actions > Advanced > Erase All Content and Settings.
• Restore the device by turning on Recovery mode.
