Hello! Thanks for asking.
Neither pdinfo nor printenv seem to produce anything much of interest unfortunately

So as for the <Huawei> shell it's unfortunately pretty restricted but also has several modes:
Initial mode has these commands:
<Huawei>?

I can see tftp and ftp are both among them but that's about it. I tried running some commands I knew from busybox here but this did not help.

An interesting thing is that you can go into the system-view menu which presents a different set of commands:

Enter system view, return user view with Ctrl+Z.
