I thought only models with a minimum OFW of 3.55 below are hackable, but I saw some threads in other forums that 250X models are actually hackable with E3. Wiki mentions that it can be directly upgraded to CFW 4.30 using 4.30 CEX checkoff, and I also saw some threads about it.
If above method is true and PS3 is directly updated to 4.30 with above method, would this be downgraded to 3.55 with 999 and install other CFW?
