What you need
A reliable microSD card (32 GB recommended).
Download the correct firmware package for your model.
Important
Keep the device powered during the update. Do not power off.
Do not rename any firmware files.
Copy all files from inside the unzipped folder to the root of the SD card.
Step-by-Step
Download & Unzip
Download the firmware package to your computer.
Unzip (extract) the package to a folder on your desktop.
Format the SD Card on the Device (Preferred)
Insert the microSD card into the CHIGEE Display.
Go to Settings → Storage → Format SD card. When formatting completes, remove the card from the device.
Copy Firmware Files (On Your Computer)
Insert the SD card into your computer.
Open the extracted firmware folder.
Copy all files inside that folder to the root directory of the SD card (not into another folder).
Safely eject the SD card.
Insert SD Card (Device Off)
With the CHIGEE Display powered off, insert the SD card.
Start the Update
Power on the device. It will automatically enter upgrade mode.
Wait about 2 minutes for the update to complete.
Do not power off during the process.
Confirm the Version
After completion/reboot, go to Settings → About and confirm the Firmware Version.
If the Device Doesn’t Recognize the SD Card
Goal: Format the card to FAT32, which is compatible with the CHIGEE Display.
On Windows:
If Windows won’t format to FAT32, use a third-party tool (e.g., Rufus) to format the card as FAT32. Recopy the extracted files to the root of the SD card and try again.
On macOS:
Open Disk Utility → select your SD card → Erase.
Format: MS-DOS (FAT) → Erase.
Recopy the extracted files to the root of the SD card and try again.
Troubleshooting Tips
Update didn’t start?
Ensure you unzipped the package and copied all extracted files to the root (not the .zip itself).
Remove any extra folders created by your OS.
Power off → reinsert SD → power on.
