## Solution

To perform a fresh/clean install of firmware on Embedded GAIA appliances via USB, the USB must use a FAT32 file system.

1. Copy the desired firmware image onto the USB (not in subfolders and not with other firmware images present).  

2. Insert the USB into "USB1" into the front of the appliance.  

3. Wait for the "USB1" LED light to activate, indicating that the USB was detected.  

4. Reboot the appliance via the WebUI, the SSH command *#reboot* , or by power cycling the appliance.  

   During the boot process, the appliance will detect the USB and firmware image.   
   The appliance will***perform a reset to factory defaults*** , followed by a fresh install of the selected firmware version.

**Note**: You may need to use Ctrl-C to interrupt the bootloader and select the relevant option.

**Note**: This procedure erases the existing image and settings.

If this method fails, connect via console and check for error messages.   

**Example of successful image verification:**   
System Started...   
/sys/devices/soc.0/fd840000.pcie-external2/pci0002:00/0002:00:00.0/0002:01:00.0/usb2/2-1/2-1:1.0/host0/target0:0:0/0:0:0:0/block/sda/sda1   
rm: cannot remove '/mnt/usb1/.read_only': No such file or directory   
Verifying image : /mnt/usb1/fw1_sx_dep_R77_990172392_20.img   
Installing image : /mnt/usb1/fw1_sx_dep_R77_990172392_20.img   
Upgrade log : /mnt/usb1/usb_image_upgrade_00-1C-7F-73-0A-F2.log   

**Example of failed image verification:**   
System Started...   
/sys/devices/soc.0/fd840000.pcie-external2/pci0002:00/0002:00:00.0/0002:01:00.0/usb2/2-1/2-1:1.0/host1/target1:0:0/1:0:0:0/block/sdb/sdb1   
/sys/devices/soc.0/fd840000.pcie-external2/pci0002:00/0002:00:00.0/0002:01:00.0/usb1/1-2/1-2:1.0/host0/target0:0:0/0:0:0:0/block/sda/sda1   
Image verification failed: /mnt/sd/fw1_sx_dep_R77_990172392_20.img   
Image verification failed: /mnt/sd/fw1_sx_dep_R77_990172392_20.img   

In the failed example, a SD card was causing the issue. Removing it solved the problem.
