I first downgrade the soft with FW 0000, then upgrade it with FW 2130. By now its look like that:
TV starts but I have no connection to it. Previously I had telnet and ftp connection but when i try to add oscam with this procedure: viewtopic.php?f=71&t=11005 all is gone

If anyone can help me how I can turn back to the "clean" root and then which procedure to use to add and start oscam on my TV I will be grateful.
Is there any soft/hard reset I must do or something ?
