STEP 2: Update Firmware

Update Firmware

Setting up for the first time? The All-in-One — Easy Setup covers this as part of the full walkthrough. This page is for updating on its own.

Before you start

Software	Zen Studio Live in the Chrome browser
Cable	A USB-C data cable, not charge-only
Port	The top port on the Zen
Button	The small blue button on the back

On a charge-only cable the Zen lights up but stays invisible to your computer. If your phone's files show up when you connect it with that cable, it's a data cable.

Update

1

Unplug everything

Remove every cable from the Zen. The next steps only work if the Zen starts out with nothing attached.

2

Hold the blue button

Turn the Zen around so you can see the back and find the small blue button. Press and hold it, and keep holding.

3

Plug in while still holding

With the button still held, plug the USB data cable into the top port of the Zen.

The order is what matters: hold first, then plug in.

4

Connect in Zen Studio Live

Click Update Firmware in the bottom-left corner, then click Connect Device. Choose Cronus Zen from the list and click Connect.

5

Start the update

Click Update to latest. The firmware now writes to your Zen.

6

Wait for it to finish

This takes a while. Do not unplug the cable and do not close the page while it runs.

When it is done you get a success message that says Firmware updated. Click Close.

7

Prefer to watch someone do it?

We have a short video that walks through connecting your Zen to Zen Studio Live.

Updating the Cronus Zen firmware

Do not interrupt the update.

Unplugging the cable or closing the page part-way through can leave the Zen with half-written firmware. Let it finish, however long it takes.

Alternative: Web Update Tool

The online firmware update tool works in Chrome and Edge, on Windows®, macOS®, and Android® — USB OTG is required on Android®.

Open the Web Update Tool

If something goes wrong
