directly from firmware 13.02 down to 9.00 through a simple USB software flash is completely impossible, and any online guide claiming otherwise is a scam The absolute lower bound of a legitimate PlayStation 4 downgrade relies on a complex hardware modification process known as a Syscon firmware revert , which can only roll a console back to its immediately preceding installed system software version. Because Sony designed the console architecture to enforce strict anti-rollback security, a retail console cannot jump backward across multiple major firmware iterations (such as leaping from 13.02 back to 9.00) without explicit, matching backups of that exact console’s unique hardware keys.
Jailbroken consoles running older firmware must never connect to the official PlayStation Network. Connecting will prompt an immediate update verification error or a permanent account/console ban.
To revert it, you must perform a hardware glitch or use a hardware programmer to patch the Syscon's internal memory (SNM). Required Tools

If you connect a downgraded console to PSN, Sony will permanently ban your console ID and PSN account. Do not attempt this on a console you use for legitimate online gaming.
Once you downgrade, you cannot update to a version that did not exist before your specific NAND flash without potentially having to redo the process.
⚠️ If your PS4 was updated sequentially (e.g., 9.00 -> 10.01 -> 11.00 -> 13.02), your previous slot will only contain the version directly preceding 13.02, making a direct jump back to 9.00 via this method impossible without historic backups. Method 2: The "Syscon + Nor" Backup Restoral The fan spun up like a jet engine
Sony designed the PS4 to prevent users from installing older firmware versions over newer ones via USB. A standard software-only downgrade does not exist. To go back to 9.00, you must use a hardware-based method known as . How Reversion Works
For the vast majority of PS4 owners, particularly those who updated from 9.00 to 13.02 without these preparations, there is no way to revert.
