that requires soldering and manipulating the console’s motherboard chips . There is no software-only file or secret USB tool that can click a button to reverse your system update. If you see websites or videos claiming a simple software-only installer for a "13.02 to 9.00" downgrade, they are malicious scams trying to deliver malware or deceptive links.
🛠️ Understanding the Hardware Revert Process (For Advanced Users)
The PlayStation 4 maintains on its motherboard: an active slot and an inactive backup slot.

Download a modified PS4UPDATE.PUP file, put it on a flash drive, plug it into your console, and run "Update System Software" in Safe Mode to magically roll back to 9.00.
In the homebrew community, firmware 9.00 is the "top" target because:

The search for "ps4 downgrade 1302 to 900 top" is ultimately a search for something that does not exist in the form users hope for. Sony's security architecture effectively prevents any simple, legitimate downgrade. While a hardware-based "Firmware Revert" is possible under very specific circumstances, it is an immensely complex, high-risk, and costly procedure that is out of reach for 99.9% of users.
This is the only semi-viable path. A PS4 maintains two "slots" for system software: an active slot and an inactive slot containing the immediately preceding version. If you updated directly from 9.00 to 13.02, 9.00 might still reside in the inactive slot. However, if you updated from 12.52 to 13.02, you can only revert to 12.52. Hardware Requirements for Reversion
You must solder your flasher to the motherboard points and create a backup of your current firmware (a "NOR Dump"). it is an immensely complex
Downgrading your PS4 from 13.02 to 9.00 can provide a range of benefits, including the ability to jailbreak and run homebrew applications. However, it is essential to carefully follow the steps outlined in this guide to avoid any potential risks or complications. Additionally, users should be aware of the potential risks of downgrading, including the possibility of bricking their console.
