Whenever I try to build for Tizen I get a Black screen...

Hi guys,
whenever I try to build for Tizen I get a Black screen. The game is actually playable (with sounds and stuff) but there's just a black screen on the emulator. I tried pretty much everything I read here in the forum (OPEN GL 2 only, changing textures to RGBA, emulator settings, deselecting options on build settings, etc.) but to no avail.
I hope somebody can help me.
Thank you,
Gabriele

EDIT: I write this for everyone is struggling with this problem. This issue seems to be unsolvable but I tried to send it to Tizen for the review anyway and it works on their devices. So, assuming your application works within the Unity editor, be confident and send the application for the review.
Regards,
Gabriele
