When I updated our PV system with Cerbo GX from 3.55 large to 3.60 large (NodeRed Active), Cerbo GX started to blink red LED, then after while green LED and I was waiting fro green and blue, like always before, but it did not. Stayed at blinking green LED. Display GX Touch 50 was backlit, but no other signs of life on it. VRM was connected and provided basic data of the system, but RemoteConsole on VRM or direct IP connection to GUIv1 was not functional, displayed partial graphic without menu. GUI v2 was luckily working, so I was able to rollback to 3.55, which is fully working. Tried it again, also with NodeRed disabled, no change, both RemoteConsole GUI v1 AND physical display GX Touch are blocked with FW 3.60

Problem solved. Display GUI v1 functionality was affected by dbus-serialbattery driver. After uninstallation of the driver everything works normally.
