I'm having a similar problem with SS.
I just wiped the stock slot, while on slot 1 with a custom rom. I can't boot into SS anymore.
I can see the SS boot option every time I start my phone, but my screen doesn't respond to touch. Neither recovery or continue to OS. My current custom rom boots fine, but I can't get back into recovery
