MHI2_ER_AU57x_S2519 MU0389 - Smartphone interface not showing up

[mathiasmrn]

Hello.

I'm on MHI2_ER_AU57x_S2519 MU0389. I successfully patched the unit and activated everything. FECs are all into place but the Smartphone interface won't appear in the menu. What's going on? I've tried everything, even used VCDS to activate it. Nothing works.

EDIT:
I forgot to mention that when I was plugging the phone into the first usb port (phone logo) it wasn't recognized, only in the second port. But after removing the patch and getting the software back to stock it is working again.
