I think you mean me!That's the second person in two days to have similar problems IIRC
Well I'm having more problems than I did before I set out to run the custom firmware. Its been a little while since I used the Humax TV Portal, but there has been quite a few things that have changed to muddy the waters since then.
I have installed the custom firmware, and I have had two router firmware upgrades since then, and now I've changed the hard disk.
It is possible that my Humax has been able to at least once access sites outside my router, because just after I attempted to install the WebIF software using a USB stick*, it did briefly download the package list but said the web interface had already been installed, I visited the Custom Firmware webpage** because I hadn't realised that the USB method had worked correctly, because I was expecting a prompt either on the TV or the front panel, but nothing seemed to happen.
Today after reading this thread I've tried accessing the TV Portal but nothing is happening other than the Web Portal message on the Humax display.
Back in June for one day I got a strange error saying "Humax STB Only!", resetting the box made no difference but the next day it was all back to normal.
* because of the error message listed at the top of this thread
** so all times but once the webpage method failed every time I ran it
