Firmware Versions
PlayStation 4 system software is identified by a version number such as a major release followed by minor revisions. Sony has released many versions over the console's life, and each one matters because the PS4 cannot be downgraded.
You do not need to memorize every release. What matters is understanding the general pattern of how firmware relates to homebrew support.
| Version group | Typical homebrew status |
|---|---|
| Older releases | Most likely to have a mature, well-documented jailbreak |
| Middle releases | Frequently supported, depending on available entry points |
| Newest releases | Often unsupported until researchers find a method, if ever |
Because new firmware patches the entry points older methods rely on, there is a natural lag: the latest version is usually the last to gain support, and sometimes never does. Earlier versions tend to be the safest place to be if homebrew is your goal.
Whatever version you read in Settings > System > System Information is the version you keep forever unless you update — and updating only moves you upward, never back. Treat your current number as a fixed asset to protect.
Before starting any project, check current community resources for the exact firmware ranges that have working methods today. That landscape shifts as new versions are studied, so a guide's specifics can age quickly even though the no-downgrade principle never changes.
