Upgrade via USB memory stick (formatted to fat32 on a pc)
First extract the downloaded USB image files to some folder on your HDD.
You'll find the following files
1) root_cfe_auto.jffs2
2) kernel_cfe_auto.bin
3) boot_cfe_auto.jffs2
On USB memory stick, make vuplus\duo\ folder and copy the above 3 files to the vuplus\duo\ folder.
(Make vuplus folder first and then make the subfolder duo )
Now USB memory stick has following 3 files in vuplus\duo\ folder.
1) vuplus\duo\root_cfe_auto.jffs2
2) vuplus\duo\kernel_cfe_auto.bin
3) vuplus\duo\boot_cfe_auto.jffs2
Insert USB Memory stick into the front USB socket and then Power Off / On the VuPlus.
After power-on, VuPlus Duo automatically starts upgrade using the files on the USB memroy stick.
You can see the progress at the front VFD display.
After upgrade is finished, VFD will say that "Finished ...please reboot"
Then be sure to remove the USB, and then Power Off/On the VuPlus STB.
