I've just bitten the bullet and updated to latest official firmware and then installed latest custom firmware. My loader version is still 7.30. Should it have updated to 7.31 or is that a separate update?
I am also at loader version 7.30, and did the same as you after Humax said there is no downloadable upgrade for the loader version. And that means OTA upgrades for the main firmware will not work, so 7.30ers will have to manually download firmware upgrades via USB (which may be good news for some!)
That isn't the case. all versions of firmware including the current 1.02.28 will OTA onto a Humax that is running loader 7.30, Versions 7.31 and 7.32 don't add any extra features for the end user of an HDR, they only add utilities used in the manufacturing process
