PS3 Cex,Dex and more

You may be asking yourself, what does all of this mean? Are they codes in a certain way? What do they do? How are they helpful to me? I can answer all of this in simple ways, but I'd rather break it down.

OFW
OFW stands for official firmware. Official firmware is put out by Sony themselves, and that's what you update to when you are prompted to update in order to play SEN. OFW can be modded, which then turns to MFW, or CFW.

CFW
CFW stands for custom firmware. Most of the time you see a CFW, especially for newer firmwares above 3.55, they are a spoof. A spoof adds access to SEN when your console is on a lower firmware, such as 3.55, it "tricks" your system into thinking it is on a higher firmware to access SEN. If you hear people claiming there is a new CFW for SEN, they are lying. Jailbreaking cannot be applied above 3.55.

MFW
MFW stands for modded firmware. Modded firmware is in a sense the same as CFW, yet it has less features. MFW can also potentially harm Playstation's with a functioning disk drive, so it's just best advised to stay away from them.

DEX
Here's where it gets good. DEX stands for developer/debug firmware. This is what developers use to develop new apps, new games, and even new features. Alas, a setback is that DEX firmware does not allow SEN access. It disables it.

CEX
CEX simply means retail. When you hear CEX to DEX, that means retail to developer. It also is the same as CFW, just a different name.

SEX
SEX is what a shop would have on display. Nothing is really useful with it, just to try games on, and to see features. This is what all of those Demo firmwares are all about, such as the 4.21 exploit made by GlitchyJoey. You can't install anything with it, it's basically just for looks.

Rebug
Rebug is a spoof of some sorts, and adds a bunch of new features. There's:

SEN store previews
Package manager
Trophy unlocker
Rebug toolbox
Rebug mode

Debug
This doesn't give any features that a jailbreak does. You don't have homebrew, nor run backups. There's no point to it at all.
Hopefully this solved all your questions about this, if you have any questions feel free to PM me or leave a comment here.
