You cannot downgrade a PlayStation 4 by simply plugging in a USB drive with firmware 9.00 and clicking "install." Sony explicitly blocks older firmware installations via software to prevent exploitation.
If you decide to proceed with a hardware revert, the process typically involves the following technical steps as discussed in modding communities like Reddit YouTube guides Hardware Tools : You need specialized equipment such as a Teensy 2.0++ Raspberry Pi CH341A programmer to read and write to the console's chips. Dumping the Flash : You must solder wires to the ps4 downgrade 1302 to 900
Firmware 13.02 is fully patched against known user-land exploits. There is no public browser or kernel exploit available for this version that allows for a "soft" (software-only) downgrade.
If you happen to find a console on a lower version, do not connect it to the internet until you have disabled automatic updates.
In conclusion, while downgrading the PS4 from version 13.02 to 9.00 is theoretically possible, it poses significant technical challenges and risks. Our analysis highlights the importance of thorough vulnerability analysis and experimental testing to ensure a successful downgrade. For the latest updates and files, refer to
