The PS3 came out in 2006 and production stopped in 2017. A machine nobody supports any more doesn't have much left to lose — which is where jailbreaking starts to make sense.
The most important part, though, is the one most guides leave until last.
There isn't one route, there are two
This confuses everyone at the start. "Jailbreaking a PS3" means two completely different things, and which of the two is possible is decided by the model, not by preference.
CFW (Custom Firmware). The console's entire firmware is replaced. Permanent: you switch the machine on and it's already there. Only the older models take it — the ones that left the factory with firmware 3.56 or earlier.
HEN (Homebrew Enabler). It doesn't touch the firmware. It is an exploit that runs on top of the official firmware and it is re-enabled on every boot. It works on every model, including the Super Slims that will never take CFW.
The model is the first step
It is on the sticker underneath, in the form CECH-xxxx. Without it nothing starts.
- Fat (CECH-A to CECH-Q) — CFW or HEN
- Slim CECH-20xx, 21xx — CFW or HEN
- Slim CECH-25xx — depends on the individual machine; it is the borderline series
- Slim CECH-30xx — HEN only
- Super Slim (CECH-40xx onwards) — HEN only
Why HEN makes sense even when CFW fits
Plenty of consoles that take CFW comfortably end up on HEN instead, and not out of ignorance.
HEN writes nothing to the firmware. The console isn't opened, the NOR isn't programmed, and there is no step where a power cut leaves a brick behind. Installation happens through the console's own browser. Change your mind and a reset leaves no trace.
The price is one thing and it is visible from the start: every time the machine powers off, HEN is gone. One click brings it back, but it is one click every time.
So the choice isn't strong versus weak. It is how often the machine gets switched on. On a console used twice a week the click costs nothing; on one that runs daily, it does.
On my own Slim, which could have taken CFW, that was the whole reason it stayed on HEN.
What it gives in practice
Two things, and neither has anything to do with not paying for games.
Media server. With webMAN the PS3 sees an external drive and the network. It became the box that plays films on the television — a job a 2009 machine does perfectly well.
Backups of discs already on the shelf. They go onto the hard drive and run from there: they load faster, the console is silent, and the optical drive — the first thing to fail on these machines — doesn't spin at all.
Worth knowing first
Stay off PSN. This is the only thing that genuinely costs. Sony detects modified consoles, and the ban isn't on the account alone — it is on the machine itself.
Firmware 4.91 is fine now. The old rule was "never update". Both HEN and CFW support it today.
There is no point writing the steps here. They change with every firmware release, and a 2026 guide will be wrong next year. The right sources are PSX-Place and GBAtemp, which get updated.
Legally. Circumventing technical protection measures is not clear-cut in the EU, even on a machine you own. Homebrew and backing up a disc you already hold is a different thing from downloading games — both practically and legally.
