RUT955 failed to load menu data

Good afternoon,

I have a RUT955 device which seems not to be okay so I have reset it. Afterwards it was not accessible anymore, updating firmware via bootloader menu does not help. The device sends out a Wifi “UNKNOW_0000” which makes me able to open the login screen but not logging in.

Error: failed to load menu data

Related to Failed to load menu RU950 - Crowd Support Forum | Teltonika Networks I have the same “empty” output which needs a device repair

Can anybody help me what to do?

Thank you!
