Creating SD card with latest firmware

Step 1: Download and install Rufus

Download Rufus (portable version) from the official website: https://rufus.ie/
Run Rufus as Administrator

Before updating the firmware, you should backup your current layout configuration to restore it after the update.

Open WomoNET app and go to settings
Select Advanced Editor
Copy the complete JSON content of the layout editor and save it in a text file (e.g. layout-backup.json)
Keep this file safe - it will be needed after the update

Step 3: Download latest firmware

Download the latest version of WomoNET Core OS firmware from here: https://s3.womonet.io/core/index.html#core-os/. Only the file with .wic.bz2 extension is needed.
Insert micro SD card (8GB or larger) into computer

Step 4: Flash SD card with firmware

Open Rufus
Device: Select micro SD card
Boot selection: Click “SELECT” and choose the downloaded firmware file (.wic.bz2)
Click START
Wait for flashing to complete (5-10 minutes)
Safely remove SD card

Step 5: Insert SD card into WomoNET.core

Insert prepared micro SD card into the SD card slot of the WomoNET.core board:
Ensure the card is fully inserted
Connect power supply

WomoNET.core will automatically boot from the SD card and load the new firmware.

Step 6: Restore layout configuration

After successfully updating the firmware, you can restore your backed up layout configuration:

Open WomoNET app and navigate to Settings → Advanced Editor
Select and copy the complete content of the previously saved text file (layout-backup.json)
In the Advanced Editor replace the entire JSON content and save the configuration
Reload the app (refresh page) for changes to take effect
Verify that all layout elements have been correctly restored
