Stuck at installing or Get Forbidden Icon

Hi, I downloaded the macOS Sierra beta today and created the USB with "createinstallmedia" but I get a forbidden icon and/or stuck in the last process before starting the installer. I used the same USB with Clover and respective kexts that I use for boot El Capitan 10.11.6 (installer) without problems. Any ideas?

I using (all in the latest version):
- NullCPUPowerManagement.kext
- FakeSMC.kext
- FakePCIID_XHCIMux.kext
- FakePCIID.kext
- AppleIntelE1000e.kext
- A USB ports unlocker kext...
