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 recover your Zen and get back to gaming.

Error Codes

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, Zen Studio has possibly become corrupted, 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 ever get an E2/E3 error code, it is highly recommended you change any USB cables you're using as they may have a fault that is contributing to this problem.

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).

E2XXX Error Code

An E2 error code like E2021 usually happens when you've programmed a corrupt or incompatible script to one of Zen's memory slots.

E3XXX Error Code

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

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.

Removing these error codes requires a Full Factory Recovery. This is done by following the 5 steps below:

Step 1: Hard Reset

1. With nothing connected to the Zen, press and hold down both of the Cronus Zen left and right blue buttons - 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. UNPLUG EVERYTHING FROM THE ZEN AND WAIT 30 SECONDS BEFORE CONTINUING TO STEP 2.

If your Cronus Zen has not reset correctly 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 (try using a powered USB hub)

Note 1: If the Zen displays Error Code E3001 or E3002 with glowing RED RGB LEDs after you perform a hard reset, the Zen has likely developed a fault and should be replaced under its warranty.

Note 2: If nothing is displayed on the LED screen, the Zen has likely developed a fault and should be replaced under its warranty.

Step 2: Downgrade Firmware

You must first download the Collective Minds Update Tool💾and be connected to the internet.

1. Make sure you left the Zen untouched with nothing connected to it for 30 seconds after performing a hard reset before continuing to this next step.

With nothing connected to the Zen, press and hold the reset button on the bottom of the Zen. This step is very important, the button must be held down BEFORE a USB cable is connected.

2. With the reset button still held down, connect a 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).

Pro Tip: If your USB ports have low power, you can also connect your Zen using a powered USB hub.

3. Let go of the reset button as soon as the Zen OLED Message Screen displays 'Zen Bootloader'. The RGB LEDs will now glow Blue/Purple to show it's ready for the next step.

4. Open the Collective Minds Firmware Update Tool and it 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 (try 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, be sure to note each step that you have done to get to this point and post a ticket to the Cronus Support Center where a professional can help resolve your issue.

5. Slide the 'User the Latest Version Available' toggle to the left to view all the available firmware versions. Select the oldest firmware version from the bottom of the list (2.0.3-beta.105), click Continue then Click Begin Update to begin programming.

Once complete, disconnect everything from the Zen and wait a few seconds before proceeding to Step 3.

Step 3: Upgrade Firmware

Unplug everything from the Zen. Now Follow Steps 1-4 as above, then for Step 5.....

5. Click Continue then Begin Update to update your Cronus Zen to the latest firmware version.

Step 4: Restore Zen Studio

It is also possible for a Zen Studio install to become corrupted and cause error codes after programming to the Zen. The solution is to delete the CronusZen directory which is located here:

%AppData%\CronusZen

You can navigate to this folder easily in Windows 10 by using the search feature 🔎

Make sure Zen Studio is closed before deleting the CronusZen folder.

Once deleted, you can open Zen Studio again and the CronusZen folder will be recreated once you have successfully connected a Cronus Zen.

Step 5: 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

Your Cronus Zen should now be fully restored to its default state 👍

If your Cronus Zen is not detected by Zen Studio, it is usually one of these issues:

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

  2. USB Port Low Power (try a powered USB hub)

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

Note: In the unlikely event that you have checked all these steps and it is still not detected by Zen Studio, the Zen has likely developed a fault and should be replaced under its warranty.
