help with PS3 Hfw 4.86

Good day mate!!!

I have a slim PS3 CECH-3001B.

recently JB with HFW 4.86, HẸN 3.0.2, multiman v4.85.01, webman 1.47.35:


1) how can I resolve black screen when I start a game ? the only way to exit is to press and hold the power til it shuts down.

2) i wish to be able to play 3D ISO movies, will I be able to and how?

3) I assume, I CANNOT install CFW on MY ps3........correct?

thank you.
