Error Codes
Why do these error codes happen? They usually emerge from a poorly coded script, an old firmware version that doesn't support newer GamePacks, or because you're using a controller, mouse, or keyboard not supported by Cronus Zen.
Before continuing, it is essential that your Cronus Zen firmware is updated to - here are the Firmware Update Instructions for your convenience.
E3 error codes, like E3001 or E3002, signal a system crash caused by specific events. Fortunately, they can be easily recovered by simply unplugging all USB cables from the Zen for at least 10 seconds, then reconnect.
The most common triggers behind these errors are:
- Faulty Scripts: The primary offender. For issues here, you'll need to reach out to the script's creator. Remember, we provide GamePacks, not scripts.
- Unsupported Device: Ensure your controller/mouse/keyboard is compatible with Zen.
- Misconnected Hardware: Even supported controllers can cause errors if plugged into the wrong USB port.
- PS5 DualSense Crash: Using this controller without the correct firmware will crash.
- USB Cable Check: Always double-check that all USB connections to the Zen and the controller are confirmed working and secure.
If one of these consistently triggers an error, congrats! you've nailed down the issue and can proceed accordingly.
Stack underflow and overflow errors are commonly associated with using a GamePack or Script designed for a more recent firmware than the one you're currently running (most likely 2.1.0 Beta 50). It's essential to make sure you've updated to .
Recovery is easy: Unplug all USB cables from the Zen for a minimum of 10 seconds and then reconnect. Should you still face persistent stack errors with a specific GamePack or Script, reach out to its creator for a solution.
Persistent error codes suggest your Zen might be faulty. Before considering a warranty replacement, it's worth attempting a hard reset to restore factory settings and clear memory slots. This is a one-time procedure, but be mindful that it's not a foolproof solution.
Start with nothing connected to the Zen. Press and hold down both P1 and P2 buttons together (the two large blue buttons either side of the OLED screen) - don't let go!
While holding the buttons, connect a USB cable from the Zen's rear CONSOLE/PC USB Port to any PC or Console (any USB power source will work).
Keep pressing the P1 and P2 buttons for a minimum of 4 seconds. Wait for the Zen RGB LEDs to flash in a sequence: RED, GREEN, and BLUE. If successful, the Collective Minds gear head logo will display on the Zen OLED Message Screen.
