Update & Downgrade Firmware Manually

Update & Downgrade Firmware Manually

To manually update or downgrade the CHIGEE Display firmware using an SD card, follow these steps:
  1. Download the firmware package
  2. Insert the SD card into the CHIGEE Display and format it (Settings > Storage > Format SD card).
  3. Insert the SD card into your computer and copy the firmware file (Extract the zip file) to the root directory. Do NOT change the file name.
  4. With the device powered off, insert the SD card into the CHIGEE Display.
  5. Power on the device - it will automatically enter the upgrade mode. Wait for the update to complete (around 2 minutes). Do not power off during the process.



If your device can't recognize the SD card, and the device won't boot up to format it, here's a workaround: Try formatting your SD card to the FAT32 file system, which is compatible with the CHIGEE Display. 

For Windows PC:

Use a third party tool like rufus 

For Mac:

Open Disk Utility, then click your SD card > Erase > Format > MS-DOS (FAT) > Erase
