Emergency Recovery

Quickly restore access to Cronus Zen if the device ever crashes with an error code or becomes corrupted.

Any time your Zen crashes with an error code or simply refuses to respond, we have a number of fail-safe procedures in place so that you can easily recover your Zen and get back to gaming.

Why do Error Codes Happen? Error events are usually caused by compiling or programming a badly coded script, using a script that is designed for a newer firmware version, or using an input device (mouse, keyboard, controller etc.) that is not compatible - it does NOT mean your Zen is faulty. This is why it is also important to make sure your Zen is updated to the latest firmware at all times, and that any script you use has been verified by the author or another user to be compatible with Zen.

If you are updated to the latest firmware and find a script that causes Zen to crash, click here to post a report with a copy of the script and a member of the support team will take care of it for you (example of a reported E2021 error with GPC script).

E3 Error Codes

Emergency Bootloader

An E3 error code like E3001 or E3002 is a full system crash that usually happens when one of the following occurs:

  1. Updating the firmware with a bad USB cable or USB port

  2. Power loss during a firmware update

  3. Connecting an input device that is not compatible with Zen

Removing this error code requires a micro-USB cable connected to Zen's rear CONSOLE USB PORT while holding the Zen Reset Button, this will force the Zen into an Emergency Bootloader mode so that you can then upgrade the firmware.

If you ever get an E3 error it is highly recommended you change the USB cable as it may have a fault that is contributing to this problem.

1. Press and hold the reset button on the bottom of the Zen. This step is very important. Holding the button after the cable is inserted will not force past an error code.

2. Connect the short 12" micro-USB cable from Zen's rear CONSOLE USB port to your Windows PC (or a Mac running Windows). Most onboard USB ports, found at the rear of a PC, carry more power (mA) than the USB headers on the front, so we highly recommend that you connect your Zen directly to onboard USB ports, especially if you are using Mouse & Keyboard (not applicable to Laptops/Notebooks).

3. The Zen OLED Message Screen will display 'Zen Bootloader', and the RGB LEDs will glow.

4. The Collective Minds Update tool will detect the Cronus Zen and display its Serial Number and current Firmware version. Hover your mouse over the device info and click to continue.

If your Cronus Zen is not detected at this point it is usually one of these issues:

  1. Bad micro-USB cable (even new cables can be faulty, try another)

  2. USB Port Low Power (also connect the mini-USB cable to Zen's PROG USB port, or use a powered USB hub)

  3. You are using Windows 7 and didn't install the driver patch (See the Downloads page)

  4. Other Cronus software is open - they must be closed (Cronus Pro, Zen Studio etc)

  5. A corrupt USB driver (remove using Windows Device Manager)

In the unlikely event that you have checked all these steps and you're still having issues, you should post a ticket to the Cronus Support Center where a professional can help resolve your issue.

5. Click Continue then Begin Update to update your firmware to the latest version (you can also downgrade the firmware👈 at this point if you are stuck with a corrupt version that will not upgrade).

If you have an input device like a mouse or keyboard that causes an E3XXX error each time you connect to the Zen, it's most likely that the device is not yet supported, or perhaps a driver bug in the firmware. To get this resolved we ask that you to post an Unsupported Device👈 report to this section of the Cronus Community Support Forum👈 , so that it can be investigated by our development team.

Downgrade Firmware

If your Zen won't update, or the firmware version is showing as 0.0.0, first performing a firmware downgrade will usually do the trick 👇

If the update fails to download the firmware it is usually one of these issues:

  1. Not connected to the internet

  2. Security software is blocking the download. (Temporarily disable Anti-Virus or Firewall).

E2 Error Codes

Hard Reset w/ micro-USB cable

An E2 error code like E2021 usually happens when you've programmed a corrupt or incompatible script to one of Zen's memory slots. This method uses a micro-USB cable connected to Zen's rear CONSOLE USB Port while holding down both of Zen's P1 and P2 buttons which will clear the memory slots, enabling your Zen to boot again.

  1. Press and hold down both of the Cronus Zen left and right blue buttons (P1 & P2) - don't let go!

  2. Connect a micro-USB cable from Zen's rear CONSOLE USB Port to your Windows PC (or a Mac running Windows).

  3. Keep both the P1 and P2 blue buttons held down for at least 4 seconds until the Zen RGB LEDs start to flash RED-GREEN-BLUE. The Collective Minds gear head logo will now display on the Zen OLED Message Screen indicating your Zen is fully functional again.

  4. Access has now been restored to your Cronus Zen. You should now perform a factory reset (Zen Studio 👉 Device 👉 Factory Reset).

If your Cronus Zen has not reset correctly at this point it is usually one of these issues:

  1. Error Code 3001: (See Emergency Bootloader instructions)

  2. Bad micro-USB cable (even new cables can be faulty, try another)

In the unlikely event that you have checked all these steps and you're still having issues, you should post a ticket to the Cronus Support Center where a professional can help resolve your issue.

Hard Reset w/ mini-USB cable

An E2 error code like E2021 usually happens when you've programmed a corrupt or incompatible script to one of Zen's memory slots. This method uses a mini-USB cable connected to Zen's left side PROG USB Port while holding down both of Zen's P1 and P2 buttons which will clear the memory slots, enabling your Zen to boot again.

  1. Press and hold down both of the Cronus Zen left and right blue buttons (P1 & P2) - don't let go!

  2. Connect a mini-USB cable from Zen's PROG USB Port to your Windows PC (or a Mac running Windows).

  3. Keep both the P1 and P2 blue buttons held down for at least 4 seconds until the Zen RGB LEDs start to flash RED-GREEN-BLUE. The Collective Minds logo will now display on the Zen OLED Message Screen indicating your Zen is fully functional again.

  4. Access has now been restored to your Cronus Zen. You should now perform a factory reset (Zen Studio 👉 Device 👉 Factory Reset).

If your Cronus Zen has not reset correctly at this point it is usually one of these issues:

  1. Error Code 3001: (See Emergency Bootloader instructions)

  2. Bad mini-USB cable (even new cables can be faulty, try another)

In the unlikely event that you have checked all these steps and you're still having issues, you should post a ticket to the Cronus Support Center where a professional can help resolve your issue.

Factory Reset

A factory reset erases all memory slots and returns all Cronus Zen options to their default status. Be sure to check you have the latest version of Zen Studio before continuing.

Zen Studio 👉 Device Tab 👉 Factory Reset

If your Zen won't respond to a hard reset, or the firmware version is showing as 0.0.0, a firmware downgrade will usually do the trick 👇

Restore Zen Studio

If you get a message saying Failed / Error when trying to program a script or GamePack, if Zen Studio is crashing when trying to program a GamePack, or if M&K Settings are not being writing to the Zen - basically anything that is failing to program to the Zen device from Zen Studio, it is usually because your Zen Studio install has become corrupted.

The solution is to delete the CronusZen folder which is located here:

%AppData%\CronusZen

You can delete the folder manually or download and run the Scrub Zen Tool 👇 which will backup your CronusZen directory to C:\CronusZenBackup and then delete the original Cronus Zen directory.
