PS3 PS3 broken Blueray Drive bypass

[Micolay]

I already have a installed and still have access to my XMB, can I try installing CFW noBD 4.91 using ps3xploit or will I brick my console. It's a ps3 fat CHECH-G04
N.B my console goes to a black screen each time I try to launch HEN or any game/app
Any fix for my case? thanks in advance
