New to PS3

Hello, I wanted to ask some info cause everything i read so far is still a bit confusing. I currently own a WII which i can run my homebrews, Which means i can follow directions and read.


Recently my brother gave me his PS3 but its on firmware 4.21, this is a used system. From what i read i need to be on firmware 3.55 to jail break my ps3. I also read that if I'M 3.56 or 3.60 or 3.61 or 3.66 or .377- NO Downgrade, NO Jailbreak and NO CFW!


So im not sure if i can downgrade mine.


Another question i had is, i read in a few places that if you downgrade then you cant go online with the PS3. but then i also read that if you install custom firmware that you can.

the model of my ps3 is a cech2001B

Thanks

as stands i think all access to psn on 3.55 is still available through different methods i havent tried in awhile as for downgrading 4.21 im not sure its possible yet but im sure E3 will soon sort that out but you will need a E3 flasher or progskeet they both work with the other fw you mentioned but with 4.20 and 4.21 they have only just been released but hang in there it will be available soon im sure

I believe Jay/Crab cfw works on 3.56 but its in spanish.you should ask your brother if he remember what ofw it came with before you buy one of those downgrading tools.If it does came with 3.55 or lower then your in luck.

thanks, i ask him and he wasnt sure himself. I guess ill have to experiment with it
