Let’s break down what each error means for your specific situation.

Run the dump through the BwE Patcher tool. The tool edits the boot slots, tricking the Syscon into thinking the active slot is the previous firmware (9.00).

Every PS4 motherboard contains a chip. This chip acts as the gatekeeper of the console. It stores the console's "lowest firmware version" history. When Sony releases a system update, it often includes updates to the Bleeding Edge secure bootloader.

If you are looking to downgrade a PS4 from a modern firmware to a legacy one, here is the technical reality, the specific risks involving error codes like SU-42118-6, and why the "USB method" is widely misunderstood.

This method involves soldering a microcontroller (like a Teensy 2.0++) directly to the PS4’s Syscon chip (the chip that manages power and fuses).

Which of the following is a legal concern when downgrading firmware using third‑party tools? A) Patent infringement B) Circumventing digital protection measures (anti‑circumvention laws) C) Trademark dilution D) None — it’s always legal

: You can only reach version 9.00 if it was the version installed immediately before your most recent update. Reaping a jump from 13.02 all the way back to 9.00 is impossible unless 9.00 was that previous version. Hardware Revert Process

If you have the technical skills and the correct hardware, the process follows these main phases: 1. Dumping the NOR Flash and Syscon

: Use your hardware flasher to create multiple backups of your current NOR and Syscon data.

, you modify the "active slot" in the system's firmware to point back to the previous version.

If you search online for "PS4 downgrade 13.02 to 9.00," you will find dozens of websites, TikToks, and YouTube videos offering custom .PUP update files or specific "downgrade software".

Before investing in hardware tools, you must understand the strict limitations of the reversion process.

[ PS4 Motherboard ] ---> [ Read/Dump NOR Flash & Syscon ] ---> [ Patch Code via Teensy/Raspberry Pi ] ---> [ Toggle Active Core OS Slot ] Necessary Hardware Elements To perform a true hardware revert, a modder requires: : A device like a Teensy 4.0 Go to product viewer dialog for this item. Go to product viewer dialog for this item. Raspberry Pi Pico Go to product viewer dialog for this item. configured to interface with the motherboard chips.

This is not a project for beginners. It requires precise micro-soldering and hardware manipulation tools:

If you updated from 13.00 to 13.02, you can only revert back to 13.00 (not 9.00).

firmware in two separate slots on the Syscon chip. A "revert" swaps these slots. : You can only go back to the version you were on directly before updating to 13.02.

There are two primary camps of users searching for "PS4 downgrade 1302 to 900":

If your solder joints bridge or your chip dumps are corrupted during the read/write process, you can permanently destroy your console.

: This is a high-risk procedure. One bad solder joint or a corrupted data dump can permanently "brick" (break) your console. Soldering Skills
