Can I downgrade my PS3 help?

[moritaka]

I have a ps3 slim CECH-2503B, my date code is 0D, with minvercheck I got 3.50, I do not have any cfw on my ps3 now and I don't have a flasher, how can I get CFW on my ps3?

Yes. You will need a flasher or look in the marketplace section here for someone to do it for you.

if you are ofw 3.50 now, then just update to 3.55 ofw and then install the cfw you want. if your system is above 3.55 ofw then you need to downgrade and only if your system came with ofw 3.55 or less when you bought the system.
