user wants a long article about "ps4 downgrade 13.02 to 9.00". I need to follow the search plan. First, I'll search for PS4 firmware 13.02 and 9.00 information, downgrade methods, feasibility, and related community discussions. I'll also search in Chinese. search results show various pages. I need to open some of them to gather detailed information. I'll open the consolemods FAQ, the firmware revert page, the PSDevWiki page, the Bilibili page, and the gbatemp threads to understand the technical details and community feedback. search results provide comprehensive information. The consolemods wiki clearly states that downgrading is not possible via normal means and requires hardware backups and soldering. The Bilibili video suggests a newer method that might allow downgrading to 9.00 using a free tool, but with limitations. The GBAtemp threads provide community insights. The Wololo article discusses reverting to previous firmware without backups. I need to structure a long article that covers the reality of downgrading, the technical methods, risks, and alternatives. I'll organize it with sections on firmware overview, official downgrade impossibility, the syscon method, prerequisites, risks, and FAQs. I'll cite the relevant sources. simple, blunt truth is this:

It's important to be cautious. The PS4 modding scene has seen progress, with some firmware versions up to 13.00 being jailbroken using new Blu-ray exploits. However, for , there is currently no public kernel exploit, making a jailbreak impossible even if you had a 13.02 jailbreak tool. Be wary of any website or seller promising a simple software downgrade, as these are almost certainly scams.
Therefore, the direct downgrade from firmware 13.02 to 9.00 on a standard retail PS4 is technically impossible via software means. The system’s "Secure Boot" process verifies the firmware version against the burned fuses before the operating system loads. If the version number does not match the expected minimum version dictated by the hardware state, the console will refuse to boot, resulting in a "soft brick." While hardware modifications exist—specifically the installation of a "Modchip" (such as the Au or Beetle modchip)—these are invasive, require soldering skills, and generally allow the console ps4 downgrade 13.02 to 9.00

Attempting the physical Syscon revert method carries a high risk of permanently destroying your console. A single bridged solder joint or an corrupted memory dump can permanently brick the PS4, rendering it useless. This method should only be attempted by professional electronics technicians.

: You can only revert to the immediately preceding version . If you updated from 13.00 to 13.02, you can only go back to 13.00— not 9.00 —unless 9.00 was the very last version you had installed before your current one.

The only way to downgrade a PS4 is through a "Firmware Revert," a hardware-based modification that works by manipulating these chips directly.
The primary reason a standard software downgrade is impossible comes down to the console's physical security hardware. The PS4 stores its system data using two primary components on the motherboard:
from firmware 13.02 to 9.00 . Downgrading a PlayStation 4 is fundamentally different from updating it; while Sony provides "Update" files via USB, they do not provide "Downgrade" files, and the system is designed to reject any firmware version lower than the one currently installed.
