Cosy 131 4G EU unresponsive, keeps rebooting every 20sec

Configured the device with USB-stick from eCatcher to set the LAN IP. After the configuration the device Is not reachable, I have tried connecting to It with only a switch between my computer and the device. Every 20 seconds, the unit powers of the LAN port and the USR-led goes red for 2 seconds and comes back.
The unit cannot be discovered with eBuddy.

I have tried the “Level2” reset but the unit keeps rebooting, cabling has been checked, shielding has been wired. I have also tried to put a recovery firmware on a USB-stick but nothing happens. No IP-conflicts.
Any advice?

Since you are in the EU, I would recommend contacting their office for support on this device. Please call:
