4G LTE Starlight offline since update to firmware v1.1.1.1

My Eufy 4G LTE Starlight camera is offline (updating over 72 hours) since the update to firmware v1.1.1.1.

Does anyone know what has changed with firmware v1.1.1.1? Are there release notes?

My camera is 800 km away. Are there any possibilities for remote configuration, for example (reboot or APN config) via SMS. The camera is logged into the mobile network, receives SMS but has no IP connection!
