I just bought a CECH-2501B PS3.
I want to put REBUG 3.55 CFW on it, but the problem is, I don't know if its safe to downgrade it.
I messaged the seller to find out what firmware it is on, but haven't gotten an answer yet.
I looked it up online too, and the problem is some sites say it can be downgraded, some say it can't.
Can anybody help me with this?
