As expected: the SAP module queries for the SIM access profile, gets an answer from the phone and then does nothing, nada, nichts. The only possibly strange thing is that the phone reports the SIM access profile twice. I don't know if that's the reason for the following silence.
In case your m8 is already rooted you may try my app. If this still doesn't work please mail me another log.
Maybe it helps to simply reset the SAP module to factory settings and try again.
