Once you've downgraded to 9.00, you can install custom firmware (CFW) to unlock the full potential of your PS4. This involves installing a CFW package, such as Henkaku or Mira, which provides a range of features and tools for homebrew and customization.
Once you’re on 10.50, you cannot go back to 9.00. If jailbreaking/homebrew is your goal, you will need to either:
If you want to jailbreak your PS4, check your current firmware. If you are on , you can now use the PPPwn exploit . PPPwn : Works on 9.00, 9.60, 10.01, 10.50, 10.71, and 11.00.
You cannot bypass this check by installing firmware via a USB drive in Safe Mode or by formatting the hard drive. ps4 downgrade 10.50 to 9.00
No software hack has ever bypassed this fuse check on a retail PS4 (except for very specific early models with hardware flaws, which we’ll cover).
You solder fine wires to the tiny pins of the Syscon and Flash memory chips.
The modding community consensus is clear: "Du hast hier 10.51 genannt, damit kannst du auf 10.5 zurück, aber nicht auf 9.00" (translated: "You mentioned 10.51 here, so you can go back to 10.5, but not to 9.00"). Similarly, Spanish-language communities confirm that "Con una 10.50 NO vas a hacer downgrade" (translated: "With a 10.50 you're NOT going to downgrade") unless you possess exceptional skills and equipment.

You write the edited data back onto the chips.
To recap, a software shortcut to downgrade your PS4 from 10.50 to 9.00 does not exist. The only verified path back to 9.00 is through hardware Syscon glitching, which requires precision micro-soldering and a precise update history. If you do not possess advanced hardware modification skills, your best option is to keep your console offline to preserve its 10.50 status, or look for a secondary console that already meets the 9.00 requirements. To help clarify your options, tell me:
To completely disassemble the PS4.
The main reason to downgrade your PS4 from 10.50 to 9.00 is to enable the installation of custom firmware, also known as CFW. CFW allows users to run homebrew applications, play games from other regions, and even exploit vulnerabilities in the system. The firmware version 9.00 is particularly popular among developers and enthusiasts because it provides a relatively stable and secure environment for experimenting with custom code.
If done correctly, the console boots into the old firmware slot. Risks and Limitations of the Hardware Method
