MangOH yellow wp7702 cannot connect to the Octave cloud after updating its firmware to 0.5.0


After updating the device firmware to version 0.5.0 the device booted, connected to the Octave cloud for several seconds. Then the connection was lost and it can’t connect to the cloud again ever since. It boots, activates the vegas mode for several seconds, then the vegas mode turns off, no connection to the Octave cloud.

This is what I got from SSH:

Could you please help me to perform diagnostic and restore the device functionality.

Can you connect to a USB power that can supply the necessary power?
can you show cm data output?
