Help Unlocking iphone 5s sprint 7.1 +rsim nano cloud

I'm unable to unlock my iphone 5s sprint 7.1 with rsim nano cloud, I try the instructions, I try different guides with no luck. I'm stuck in the activation screen when I pop my carrier sim card with rsim nano cloud. I have the original sprint sim, phone is jailbroken with the A:3G/4G上网（5S/5C) WCDMA and A1: Commcenter patch and already tried rsim air2 as well. Can somebody help me?
