Hello everybody, and huge thanks for maintaining this port! Now my XA2 Ultra has a big brother

I just received my SGP621 (with LTE that is) and after some file hunting, managed to flash it with 2.2.1.18-alpha1, and as I write, it's updating to 3.0.0.8 as I didn't dare to upgrade stright to 3.2.1.19. Should it work?

I have this device as a development thing mostly, so I can mess around with it. If there's something that needs to be tested or checked, please let me know!
