I have found a answer to the problem I was having with my Humax box where auto backup had stopped working in scheduled events/backup & restore.
the solution that has worked for me was to load webif by usb stick.
go to
http://wiki.hummy.tv/wiki/Manually_loading_Features_from_USB
where it says
"If it is not practical to connect your Humax box to the Internet via a cable or wireless, then software packages can be loaded onto the Humax by placing them onto a USB Disk drive. The packages themselves can be downloaded from
http://hpkg.tv/packages.html. Each package is available for download as an individual file or as a bundle. A bundle contains the package itself along with all of its dependencies, and is the recommended and easiest way to install software. "
I went to
http://hpkg.tv/packages.html as mentioned & scrolled down to webif and downloaded the Bundle to usb stick
with the Humax on I inserted the stick, after a short while it stopped flashing and I removed the stick,powered the box off & then on.
it has done an auto update at approx 4.25 over the last week OK
Hope this will help anyone with the same or similar problem
