I successfully enabled rSAP on my new Redmi 4X MIUI Global 18.104.22.168 with Qualcomm-Snapdragon-CPU. My Volkswagen RNS 510 phone works great with my SIM now!
I used this solution: http://www.android-rsap.com/41-support/ ... ccess.html
It was a hard way to get the "sap_security_restrictions" into the phone.
But now, it works without the rsap-software!
It would be nicer if the software would do all this work implementing the sap_security_restrictions.
Nevertheless the rsap-Software is great - I used it noch my htc one X!
