ALL.sh and LTE_ALL.sh don't work, but UMTS_ALL.sh

ALL.sh and LTE_ALL.sh don't work, but UMTS_ALL.sh.
I set it to UMTS_ALL, but because ALL.sh doesn't work, I can't reset it back to ALL now :(
My guess is that it's becaues my router (E5577Cs-321) doesn't support all LTE bands, e.g. it doesn't seem to support LTE_900, but LTE_800, as you can see below.
So if the tool also tries to set LTE_900 when setting ALL or LTE_ALL, maybe that's why those fail?
Here is the output:

Btw, when I call /api/net/net-mode-list, I get this:

I do not own a single Huawei device anymore. So I cannot change or test anything. Sorry.
