@Waqas Glad to hear you solved the issue. Regarding the LTE firmware, if you install the build system then you select the LTE configuration and then you can see which packages are selected in the standard LTE build. https://docs.onion.io/omega2-docs/cross-compiling.html The article I linked relies on some packages you need to install so I think you may be able to just update the standard LTE build to suit your requirements.
