Safer alternatives
The reason the "1302 UPD" method fails for 99% of users isn't because the file is fake—it's a real Sony update—but because the PS4 has a complex security chain.
There is (like a USB or DNS trick) to downgrade a PS4. The process requires advanced hardware modification: ps4 downgrade 1302 upd
There is no need for a "downgrade." The solution is to repair the underlying hardware issue and then perform the required system update. Follow these steps in order:
You're looking for a comprehensive guide on downgrading your PS4 from firmware version 13.02. I must emphasize that downgrading your console's firmware can potentially brick it, making it unusable. Proceed with caution and at your own risk. Safer alternatives The reason the "1302 UPD" method
We demonstrate the exploitation of this vulnerability by creating a custom firmware image that downgrades the PS4's firmware to a vulnerable version. We then use this image to exploit the PS4, demonstrating the potential for arbitrary code execution.
Write the modified data back onto the console chips, clear any hardware error codes via a UART connection, and boot the console.

Downgrading a PS4 from firmware is technically possible but is a complex hardware-level procedure known as a firmware revert . It is not a simple software update and cannot be done through a standard USB stick or safe mode menu alone. The Core Concept: Slot A vs. Slot B
