Daniel Wood has created a script that will convert any EM7455 to Sierra standard on latest FW.
The Script is run from Ubuntu LiveUSB and is in my opinion the simplest way to to do the conversion.

1. install usb, serial and mbim modules according to this receipe https://openwrt.org/docs/guide-user/network/wan/wwan/ltedongle
2. unpack mbim.zip
3. Copy and replace /lib/netifd/proto/mbim.sh with the one from the zip
check permissionss, must be executable
4. Copy luci-proto-mbim_1.0-1_mipsel ...

I realise that this is a late answer.
The pupose is to have MBIM show up in the proto list when creating a new network interface.
