For many users, the safest and most cost-effective solution is to sell their current PS4 on firmware 10.50 and purchase a used PS4 that is already running firmware 9.00 or lower. You can often find these listed on secondary markets by asking sellers to verify the system software version in the console settings before buying. Beware of Fake Software Downgraders

Sony officially prevents downgrading to prevent piracy and system modifications. A standard PS4 firmware update is a one-way street. However, through advancements in the hacking scene, a "hard" downgrade is possible. What is Required? If you'd like, I can: Explain how to
Locate the active slot and the backup slot. If the backup slot shows firmware 9.00, you can proceed.
It's possible but unlikely. The PS4's security design—particularly the eFuse system—makes even theoretical downgrade methods extremely challenging. As the PS4 ages and community interest shifts toward PS5, major breakthroughs are less likely.
