How to update channels from userbouquet.favourites.tv

what box and image are you using bud ?
these are two examples:
[DOWNLOAD] AutoBouquets by Lraizer
[DOWNLOAD] OE-Alliance AutoBouquetsMaker.
other than that you need to manually update your channel list.
Unless you are referring to certain iptv lists.

It is not automatic, but you can ask it to reload from a browser (or wget)

http://dreambox/web/servicelistreload?mode={mode}

Mode can be:

0, reloading lamedb and Userbouquets

1, reloading lamedb only

2, reloading Userbouquets only

Replace "dreambox" with the ip address of your stb and use any web browser on your network. (PC or tablet, phone, etc)
Or telnet to the box and type:

wget -q -O - http://127.0.0.1/web/servicelistreload?mode=2
