Humax web page detailing current latest software release and instructions for loading it:
Note that (at the time of writing) the current software* release is 1.02.13, and the download button for the latest version does not display the version number (the second download button is for a previous version of software, and shows the version number).
According to the user manual (also downloadable from the web site above), as long as the unit is connected to the Internet (which means wiring it to your router by Ethernet cable
or configuring WiFi), you can also check for a new version of software (and presumably update it if a new version is found) from the system menus:
[The above] is largely correct for owners of the RM-L08 remote control (supplied with newer FVP-4000T boxes), but for owners of older boxes with the RM-L03 remote control, there is no 'FreeviewPlay' button, so all references to this should be replaced by the 'HOME' button.
I don't have an FVP-4000T to check, but I have little doubt it is possible to read the current installed software version from the same System Information menu, and I also expect that the unit is perfectly capable of updating itself automatically if it discovers a new version of the software exists. From the "Trouble Shooting" section of the manual, under "Cannot update the new software":
There is... no need to use the rear USB port, the side one also works, and in my experience is much more convenient to access.
Note the part which reads "If your product stays connected to the network, everytime
[sic] you turn off the product
[ie standby, not "off"] it will search for any updates available on air
[Internet, not broadcast]". In other words: if you leave the unit on all the time (or only turn it off to recover from a crash), it will never automatically check for a software update.
That all seems pretty clear to me. Are you saying this doesn't work? If it does work, why are you worried about it?
when its installed will ut wipe to factory settings please
I don't have one to check, but I do not expect it to restore factory defaults as a result of updating the software. The HDR-FOX doesn't, and logically if a unit reset all the user configuration (tuning, recording schedule, output preferences, etc etc) as a result of software update, there would be a lot of very annoyed Humax customers every time there was a new software release automatically downloaded and applied.
* Humax call it "software", an engineer (ie me) would prefer to call it firmware.
