If your console was running and you updated to 13.02 , your inactive slot contains 13.00.
This is the only functional way to "downgrade," but it has strict limitations. It requires soldering skills and specialized hardware (like a Teensy++ or Raspberry Pi). The Concept: The PS4 keeps a backup of the firmware version in its hardware (the Syscon chip). The Catch: You can only revert to the firmware that was installed immediately before your current update.
When you are on Firmware A and update to Firmware B, Firmware A is shifted into the inactive slot.
: The console is reassembled and booted into Safe Mode, allowing it to initialize the previous firmware version slot successfully.

Strip the console down completely to expose the motherboard.
. The PlayStation 4 architecture uses dedicated hardware tokens and an anti-downgrade mechanism tied to the console's SYSCON and NOR flash memory chips to prevent users from installing older, vulnerable software versions. However, seasoned hardware modders can leverage a deeply technical process called Firmware Reversion , which allows a console to swap back to its immediately preceding firmware version under strict hardware conditions.
Connecting fine wires to the proprietary NOR flash memory chip and the Syscon chip . This often requires carefully lifting specific chip pins to force the hardware into debug mode.
How to Revert the PS4 to a Previous Firmware (Full Tutorial)
The PS4's firmware versions are stored in a read-only memory (ROM) and are verified through a cryptographic signature. To downgrade, a user must:
Here’s a properly structured, informative piece covering the error codes (often informally referenced as “1302” by some users) and CE-34878-0 (commonly mislabeled “900” in downgrade contexts), along with the concept of downgrading from a higher firmware (e.g., 9.00) to a lower one (e.g., 5.05/6.72) .
The PS4's motherboard contains a specific component: a flash memory chip called Syscon. The PS4 saves the data of your current and one previous firmware version on this chip.
