Requisites

To update the firmware you need the following:

  • Computer with Windows/MacOS/Linux operating system
  • Chrome or Microsoft Edge as browser
  • Access to Github servers not blocked (problem only in some countries)
  • VEKTA Soundproof Mask / OMBRA USB Mic

 

1 - Find the hidden button underneath the label

At this position in the labels (for usb mic and for VEKTA mask) there is a hole through which the button can be pushed. Please locate it:

2 - Push the button while connecting the USB cable to PC

Push the button with a needle or very thin pin and hold it while connecting the usb cable to the computer. It is important that the button is being pushed down and held while connecting the cable. It doesn’t matter if it is connected via USB-A or USB-C.

(Optional: to check that this process has worked properly, the mask should now not be recognized as headset device and appear as COM device in the device manager).

3 - Update firmware with ESP script

Push the button below ("Update firmware). Chrome or Edge on desktop are required.

If you do not see a USB JTAG device in the list then you should disconnect the mask and retry the previous step: pushing the button while connecting mask usb cable to pc.

The pop-up window will list the multiple devices connected.

Choose USB JTAG device.

Use Chrome or Edge on Windows. This only works on HTTPS or localhost.

4 - Click install VEKTA-Lite v1.8b

5 - Choose "Erase Device" and click "Next"

6 - Click "Install"

7 - Wait for installation to complete

8 - After the installation is completed, click "Next"

9 - Check that everything is working properly

Now you can disconnect and reconnect the mask (without holding the flash button), and test how it works.

Don’t hesitate to contact us in case of any questions.
