Wait for developers to discover and publish new vulnerabilities. (Note: This can take many months or even years). 2. Seek Professional Hardware Modification
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 method ported for 13.02, it is unstable and crashes often, but some users report limited success.
: This process requires soldering to the console's motherboard and "lifting a leg" on a specific chip to enable debug mode. Tools Needed
PS4 Downgrade 13.02 New: Myth vs. Reality and the Hardware Revert Method ps4 downgrade 1302 new
If you tell me what you're hoping to achieve, I can tell you if there are any upcoming softmod options or if hardware is truly necessary. Firmware Revert - ConsoleMods Wiki
While a purely software-based downgrade does not exist, a physical is possible—but it comes with a massive catch. This method is known in the modding community as a Syscon Revert . How the Syscon Revert Works
The PS4’s fan whirred into a frantic, high-pitched scream. The LED strip on the console turned a deep, angry pulsing red. On his screen, the progress bar stalled at 99%. ERROR: SU-30625-6. Wait for developers to discover and publish new
Turn off automatic downloads and automatic updates in the system settings.

In reality, 13.02 silently killed two things:
The concept of a standard "software downgrade" where you put an older firmware pup file on a flash drive and run it from safe mode is fundamentally blocked by the PS4's eeprom architecture. However, a physical is possible. How the PS4 Stores Updates
The "Revert" method involves soldering a specialized chip or using a Teensy/Raspberry Pi to read the NOR and Syscon data. Because the PS4 stores the previous firmware version in a secondary slot as a failsafe, a skilled technician can sometimes toggle the console back to that specific previous version. For example, if you updated from 11.00 to 13.02, the 11.00 data might still reside in the inactive slot. However, if you have updated multiple times since your target version, that data is likely overwritten and gone forever.
