Edit: Got it working, my mistake was that the modem was set to PCIE not USB. Modem must be in USB mode. Just follow the steps below.
I flashed SNAPSHOT, ssh'd into the box did the following steps:
- Set password:
# passwd
# opkg update ; opkg install luci-ssl luci-proto-modemmanager minicom
- Make sure modem is in USB mode: guide
- reboot
I set up a new connection with the same settings I used with stock firmware. However, it does not connect

Also 5G is no listed, but it connects with 5G using stock firmware

I tried:
Different authentication methods (PAP, CHAP, PAP/CHAP) with different credentials I found online. (but it should work without authentification just like in stock FW)
I'm out of ideas, any help is appreicated
I gave it some more trying. I used a SIM card that works in the old Sptitz 4G:
The settings are identical, but no luck with the new one.
