Is there any problem with card readers?
Mine stops working after bootloader and image update. I'll try with 1.6.5 to see if it works again,
Disconnect all USB sticks and hubs from your box and make the update again with only USB stick connected
on FRONT
bootloader update and image install
very easy
you need to make update/install twice
bootloader first and after bootloader update image update/image install.
USB procedure is the same .
Format USB stick
1. Unzip the duo_cfe_3_0_usb.zip to USB stick.(There should be /vuplus/duo/cfe_cfe_auto.bin)
2. Insert USB stick into the USB port of duo and power on the box.
3. It takes just a few secs to update.
4. If Duo displays the message "Finished..reboot", remove the USB stick and restart box.
5.
Format USB stick again.
6. Unzip BH image and copy to USB stick (standard procedure)
7. Insert USB stick into the USB port of duo and power on the box.
(standard procedure).
8.If Duo displays the message "Finished..reboot", remove the USB stick and restart box.
