You probably had some non-default packages installed on your device. What commands in particular (and also for what purpose -- knowing the commands and the intent will help us recommend the right packages).

I just looked at the device you're using, and it looks like it a little module that needs an external network interface, is that correct? How does that connect and/or what is the information about the interface?
With all of these things, it's only worth doing the minimum necessary to allow you to get upgraded to the latest version. Each time you upgrade, any packages you have installed will be erased (they wouldn't be compatible anyway, you'd reinstall the packages once you're up and running).
