(adsbygoogle = window.adsbygoogle || []).push({}); I'm on version 4.78 I have a Ps3 fat cechl 04 A/B and a Ps3 slim cech2500A they are downgradable I need the whole setup on how to do it (I can watch a video) and the files I need to use to downgrade thank you

Go look up a tutorial yourself, you need to learn how to do things. I don't say it rudely, but bluntly. You can't expect to be walked the entire way, look around. Also, next time you should research before getting an E3.

First bit of advice, leave it on 4.78 do not update to 4.80.

Check YouTube there are some tutorials there and search these forums. You will get the basic understanding of how to do the process. Dogg88 actually wrote a helpful beginner guide that I referenced when I was starting out. Some of the programs tutorials mention are the same there are just updated versions which you can find with a google search.

Ok thank you
