1. Press and hold reset and power buttons simultaneously
2. Wait for the LAN led to blink 5 times (Exactly 5!)
3. Release reset and power buttons
4. The rescue page is accessible via http://192.168.1.1
5. Select the OpenWrt factory image and start upgrade
6. Wait for the router to flash new firmware and reboot

Über dmesg lässt sich der korrekte tty Port ermitteln
Modem might not be able to connect if GL.iNet Firmware was used prior.
Open ´/dev/ttyUSB3´ with picocom and execute the nvrestore commands
AT+QCFG=“nvrestore”,0
if this doesn't work, try
AT+QPRTPARA=3

Carrier muss manuell auf DTAG gesetzt werden. Workaround für 1nce steering. Siehe 1nce FAQ:
Sind die 1NCE SIM-Karten gesteert?
Auf der 1NCE Simkarte ist nur noch ein steering für Deutschland auf Deutsche Telekom hinterlegt.Weltweit wird ansonsten kein weiterer Operator gesteert.
OpenWrt geht bei einer Network Registration denial automatisch in einen failed state ohne retry.
Lösung: Jemand muss einen retry option dafür bauen, dass er retried.
Falls PDP session stirbt (SGSN terminiert, Netz geht verloren) bekommt netifd das nicht mit.
Lösung: Aktiv den data-state des modems pollen --> exit 1 lässt netifd das interface restarten
sleep 1 nach attach request reicht nicht --> Subsequenter poll liest alten state, script versucht PDP session aufzubauen während das Gerät sucht
Lösung: sleep auf 3 erhöhen. Unklar ob bessere Lösung vorhanden.
