: Many online videos showing extreme downgrades (e.g., 13.02 to 5.05) often utilize developer-specific hardware (Devkits or Testkits), which have different security protocols than retail consoles found in homes. Risks and Considerations
Because before the update, the console worked fine. After the update, it doesn’t. The logical (but incorrect) conclusion is: Roll back the update . Sony, however, designed the PS4’s bootloader (the very first code that runs when you turn on the console) to reject any firmware older than the one currently installed.
The process involves using a dual-slot system architecture within the PS4:
[Solder to Syscon & NOR Chips] ➔ [Dump Firmware Images] ➔ [Corrupt Active Slot A Data] ➔ [Trigger Safety Reversion to Slot B]
asking you to download a "13.02 Jailbreak.pkg" or "Downgrade.pup" is almost certainly a scam or malware.
For most users, this is the only viable path to a "new" downgrade. It is important to know that this process as the PS4 itself has a copy of the previous firmware.
, there is no official "Settings > Downgrade" option, nor is there currently a widely released, software-only exploit that allows a simple downgrade from 13.02 to a lower version (like 11.00 or 9.00).
Thus, a “PS4 downgrade 1302 new” that actually works would require either:
The search for "ps4 downgrade 1302 new" continues to be a hot topic. While hardware specialists can downgrade a PS4 using expensive tools and soldering, no public, one-click software exists to downgrade from 13.02 to 9.00 or 5.05.
Verify your current firmware version.
