You can backup whole firmware by 'dd' ing current /dev/tbml* and /dev/bml0/* files.
If you wanted to backup only "exe.img", than you can check where is the partition name for this firmware by 'df' command.
for example means your exe.img that runs on your TV is placed at /dev/tbml10 file.
you can copy this file with command line.
2. question: You can backup channel list before update. At some update could delete channel list. (I remember that 2004 firmware makes s such a thing). If you cankup channll'st before, than you can get your channels afterwards.
THanks.
