Public bug reported: [ Impact ]
There exist no formal API to do the FCC unlock procedure[1] in the latest version of the modemmanger. But there is a merged commit[2] that provide this functionality for intel WWAN cards in the upstream project. Lenovo have several laptops using the Intel WWAN cards, and Lenovo are struggling to give a decent way to run the FCC unlock service without this. [ Test Plan ] OEM enablement engineers and Lenovo engineers will help to test if the FCC unlock would work on certain laptops with the help of a custom package[1] provided by Lenovo which contains the FCC unlock script. [ Where problems could occur ] This is a completely new feature to support Intel WWAN cards mutal authentication, which does not affect other existing features. But the feature itself might have bugs and glitches since it is a brand new one and is not widely tested by the laptop vendors, still it is better than nothing. [ Other Info ] [1] FCC unlock procedure: https://modemmanager.org/docs/modemmanager/fcc-unlock/ [2] intel-mutual-authentication: new service, fcc-lock: https://gitlab.freedesktop.org/mobile-broadband/libmbim/-/merge_requests/157 - when the device is first shipped or comes out of the factory, it should be protected with a lock till the device reaches the end user.
