Sorry the log from device has no log files dev needed. Please recapture according #3 in link below, make sure you note down the time stamp when try to sign in.

and when you have time, take a look at #4, that is a very efficient way to get runtime and only the slogger2 logs where the EIM writes.
And please confirm if the device is pointing to STR through BDT tools?
