The PlayStation 4 hacking scene has just witnessed a monumental shift. For years, the "Holy Grail" for PS4 modders was firmware 9.00. However, a recent breakthrough has shattered previous limitations, bringing full software downgrades to firmware 13.02 (and beyond).
This development changes the landscape entirely, turning previously "unhackable" consoles into potential candidates for homebrew and game backups. Here is everything you need to know about the new downgrade methods, what they mean for the average user, and the risks involved. ps4 downgrade 1302 new
Advanced users can use a Teensy 4.0 or Raspberry Pi Pico to glitch the kernel at boot. This does not downgrade the firmware, but it allows temporary execution of code. Known as the “PicoPPPwn” method ported for 13.02, it is unstable and crashes often, but some users report limited success. PS4 Downgrade 13
First, a fundamental truth: There is no pure software downgrade for any PS4 firmware above 11.00. Sony’s Secure Boot chain and the IRD (Integrity Check) system prevent writing an older, exploitable firmware version over a newer one. Once the One-Time Programmable (OTP) fuses in the Syscon (System Control) chip are blown for 13.02, the console will reject any attempt to install a lower firmware via USB recovery—returning the infamous “CE-34788-0” error or demanding a specific update version.

Thus, any “new 1302 downgrade” must involve physical intervention.
