I also had to change the name used when requesting dhcp. It was using "root" and was giving me errors. After I changed to "a", it worked just fine.

Can you elaborate on what you exactly changed?
I tried everything in the tutorial and according to log and device everything should be fine but I have no internet.

Still works as of today with E3372 (hardware CL2E3372HM and software 22.328.62.00.1217) with OpenWrt 23.05.2

opkg update
opkg install kmod-usb-net-huawei-cdc-ncm
opkg install usb-modeswitch

Restart router, create new interface '4G' connected to eth2 (in my case) and assign to zone WAN at tab 'Firewall settings' of interface.

Stick is running in Hilink mode (hands out a 192.168.8.x address to client, stick webinterface at 192.168.81).
No pin configured on SIM.

If you need lsusb (which is not installed by default): opkg install usbutils

Also confirm this is working!
