1. Extract the file, and copy the whole folder "vuplus" include alll subfolder and files to the root of usb stick. ( inside the vuplus, there is a subfolder "solo" and inside that subfolder there are three files "root_cfe_auto.jffs2" ,"kernel_cfe_auto.bin" and "boot_cfe_auto.jffs2")
2. Power off the cloud ibox
3. Insert the USB stick (with complete "vuplus" folder on the root)
4. Power on the cloud ibox, it will automatically read the files from USB stick and USB stick will blink in blue light
5. wait until the upgrading is completed (Do not power off the cloud ibox during upgrading, do not pull out the usb stick when it blinks)
6. After upgrading is finished, power off the cloud ibox, and remote the USB stick
7. reboot Cloud ibox
