@kader73:
Your box is apparenty still able to do channel up. Channel up only works for files in the Fortis .ird format. If you have the correct bootloader as binary file you can create your own loader-ird by using the fup program. Fup is available for linux and windows. If you would like to try this option, I can tell you how to proceed. There is one proviso: you need to know the current resellerID that is in the current loader.
The simple way is to use a resellerchanger (or fup) on this file after unpacking it: http://www.hdmedia-universe.com/board/attachment.php?attachmentid=1094&d=1342114958 (loader L7.26 Octagon) and then use channel up. Your box will then have the Octagon resellerID though.
