SixFab Modem configuration in OpenWrt

Installing and Using OpenWrt
1

I'm connecting the SixFab 4G/LTE Cellular Modem Kit to my Raspberry Pi 4 and I'm trying to use OpenWrt to get it working with cellular. I've already tested the Rpi and connected it to my home wifi, but I'm having a difficult time setting up the SixFab. I've tried changing the usbmode of the SixFab to be in QMI mode, but not too sure if that worked properly as when I run usbmode -s -v -c /path/to/usb-mode-custom.json after changing the file to include the configuration from this forum but with my port ID and settings it doesn't work:
[OpenWrt Wiki] USB mode switch

After trying everything stated above, I went onto the Sixfab website to configure the Quectel online. I followed the guide to register the asset and went to details to finally get the installation code, but it seems that it's for Ubuntu and was having problems with OpenWrt. I've tried opkg update and opkg upgrade to make sure everything is up to date, but I still get an error at the end. Any tips?

Likely you meed to reset your openwrt after damage done by 3rd party script.

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

This seems more like a systemd script was applied, where one of 3gpp wan configs had to be installed, maybe new generation device added to USB driver.

Yeah, the update warning was a side note, not really related to the issue at hand.
