Here is information about customize your B series firmware.. This forum is NOT FOR USER questions or problems but DEVELOPER.
I don`t know full your model number, not only the first part, if it CI model, you could use FFB (look at my signature).
FFB (v0.8), FFB for CI+ . Get root on: C series, D series, E series, F series, H series. rooting K series, exeDSP/exeTV patches[C/D/E/F/H]
You`re running app from TV, but might not from ContentLibraryManager/Games but from ContentLibrary/Games . That`s all.
After TV restart port is closed and if you need telnet, you have to run 1e '' Run Run this Telnet Enabler'' again.
if you do that, the goal is just enable hidden firmware that exist on tv. But you must be sure you have upgraded firmware at least once.
