How do I do an offline update on my IRIS? (Mac)
Step 1. Download the firmware update file from here:

Step 2. Make sure you have a MicroSD card available that is either already formatted to FAT32 format or that can be formatted to FAT32 format.
Step 3. Format your SD card to FAT32 using the "Disk Utility" app on your Mac
Step 4. Once reformatted, create a folder called dload on your MicroSD card
Step 5. Copy the downloaded firmware upgrade file to the dload folder (Do NOT unzip the file!)
Step 6. Insert the card into IRIS and power on. Navigate to Setting->System Update, click " Offline Update" , System will check and upgrade automatically. Make sure the battery of IRIS is more than 40% full or you can just leave USB power cable plugged during the upgrading..
