Step 1: Update Firmware

The manual covers every step extensively, however, this Quick Start section is designed to skip all the details and cut right to the chase. First you must update the Zen firmware.
Current Firmware version: 2.0.6

This first step is extremely important. Do this before installing Zen Studio and do not run any scripts until you have first updated to the latest firmware.

You must always keep your Cronus Zen updated with the latest firmware as we're constantly fixing bugs, increasing functionality and improving stability. Using an outdated firmware may also cause error codes when using scripts that have not been updated.

Before you begin, make sure Zen Studio or any other Cronus software isn't open, with nothing connected to the Zen device.

How to Update Zen Firmware

Download Update Tool

1. Download the Collective Minds Firmware Update Tool (CMUPDATETOOL) 👉 from our website

Connect to PC

2. Press and hold the reset button on the bottom of the Zen. It is important to do this before connecting the Zen to your computer.


3. Connect the short 12" micro-USB cable from Zen's rear CONSOLE USB port to your Windows PC (or a Mac running Windows) while still holding the reset button.

Zen Bootloader Mode

4. The Zen OLED Message Screen will display 'Zen Bootloader', and the RGB LEDs will glow. At this point you can let go of the reset button.

Update the Firmware

5. The Collective Minds Update tool will now 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 is not detected at this point, it's usually caused by one of these:

  1. Your device has an Error Code which needs fixing (see Emergency Recovery Guide)

  2. Bad micro-USB cable (even new cables can be faulty, try one of your own)

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

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

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

6. Click Continue then Begin Update to update your firmware to the latest version.

7. Once the firmware upgrade has successfully completed, the Zen's RGB' LEDs will flash RED, GREEN, BLUE) and display the Collective Minds Gear Head logo.

The Cronus Zen OLED Message Screen has built-in screen burn protection that will clear the display after 30 seconds of inactivity.
