The PS4 architecture actually keeps a backup of the previously installed firmware version in a separate slot on the NOR flash. This is designed as a safety measure in case a system update fails midway through installation.
Only follow news from established console security researchers and developers within the PlayStation scene (such as Wololo, PlayStationhax, or reputable GitHub repositories).

To understand why a simple "v1.00 tool" cannot exist without hardware intervention, it helps to understand Sony's built-in security measures. 1. Anti-Rollback Protection ps4 tool downgrade v1.00

: A free, popular tool for manipulating NOR and Syscon backups to enable reverting.
For now, these remain theoretical—no public tool implements such advanced attacks. The PS4 architecture actually keeps a backup of
The holy grail remains unattainable—but that has never stopped the internet from dreaming.
Given these risks and requirements, an alternative is to consider a modern, easy-to-use jailbreak tool if your goal is simply to run homebrew software. Devices like the can jailbreak firmware versions 9.00, 9.60, 10.00, 10.01, and 11.00 without any soldering. This gives you access to a wide range of homebrew applications and game backups, all without the extreme risk of hardware downgrading.
The primary motivation for users on newer firmwares (like 11.02 or higher) is to revert to a jailbreakable version 9.00 or 11.00 If you are interested in this topic, I
Sony’s PlayStation 4 architecture uses robust security measures specifically designed to prevent software-based downgrades. When a PS4 updates, it burns internal fuses (syscon hashes) and updates secure keys that prevent older code from executing. Why People Want to Downgrade Their PS4
The PS4 verifies every official firmware update file using console-unique encryption keys. Any attempt to install an older firmware over a newer one is immediately rejected by the system, displaying an error indicating that a newer version is already installed. The idea of a "PS4 tool downgrade v1.00" that can bypass this simply by using a USB drive or a fake server is a persistent but myth. So, why are all the search results pointing to complex, hardware-level guides? Because that is the only way it is possible.
