: Even with hardware modding, a PS4 can generally only "revert" to the immediately preceding firmware version that was installed on that specific console. If you updated from 12.02 to 13.02, you might revert to 12.02, but jumping all the way back to 9.00 is impossible unless that console was never updated past 9.00 in the past. PS4 Firmware Downgrade: Reverting from 11.02 to 11.00
Suddenly, the console he had bought off the shelf was his again. He could back up his discs to the internal SSD. He could overclock the fan speeds. He could run emulators for retro games that Sony would never allow on the store. He wasn't playing by Sony's rules anymore; he was playing by his own.

If your console went from 9.00 to 11.00, then to 12.00, and finally to 13.02, a hardware revert will only take you back to the firmware directly preceding 13.02.

"End of the line, big guy," Elias whispered, picking up the controller. On the screen, the familiar dynamic theme of God of War was paused. But Elias wasn’t playing God of War tonight. He was playing a much more dangerous game: Firmware Roulette. He could back up his discs to the internal SSD
Let us state this clearly:
Some users ask about installing a modchip to enable downgrading. While hardware modifications exist for the PS4—such as installing modchips or modifying the motherboard—these are typically focused on enabling specific features like playing backups rather than facilitating firmware downgrades. Even with hardware modifications, reverting firmware version remains a complex process that requires specific Syscon and NOR programming.
