What do I need to backup before SamyGO flash?

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

Code: Select all

/dev/tbml10              61400     52440      8960  85% /mtd_exe

means your exe.img that runs on your TV is placed at /dev/tbml10 file.
you can copy this file with

Code: Select all

dd if=/dev/tbml10 of=/dtv/usb/sda1/backup.exe.img

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.
