The above is caused by /efs not being mounted in the android container. Mounting it at boot causes a kernel panic. Mounting it in init.baseband.rc just before enable cpboot-daemon makes cbd and rild boot properly, however the network still doesn't show up on the phone ui.

The network shows on the phone ui when ofono is configured with this config in /etc/ofono/ril_subscription.conf (without the [ril_1] lines)
