hello there how is life with you i hope you're having fun


The problem

i have friend told me that i can't do downgrade for this model serial PS3 slim Model CECH - 2503B

so i got confused and start asking why not . he told me he had been with this model for 3 or more times trying to downgrade it

but doesn't work because the yellow light well show up immediately after the process ( downgrade )

so if any one here have this model and did the downgrade correctly work 100 % just tell me because i'm thinking to buy a new one with different model

notice : the model serial you will find it in the back of your ps3 in small , white and Rectangular-shaped paper
