How can I backup an MP3 player's firmware on Linux?

Asked by Vincentt (8094points) January 2nd, 2008

Hi, I want to install Rockbox on my sister’s mp3-player (a SanDisk Sansa e200) but I want to make absolutely sure I don’t ruin the device. I can copy all the files over to my harddrive but I also want to make a backup of the firmware if possible. I believe the dd command was able to do this, but since I’ve never used it and do not have any experience with it, I’m a bit cautious; therefore I’m asking this question ;-)

Thanks in advance.

You have to check which partition the firmware is on (look at /proc/partitions for info, and do a little detective work). Then it is just

dd if=/dev/sdXXX of=my_firmware.bak

with /dev/sdXXX the location of the device’s firmware.

Good luck.

Thanks, I’ve already managed to install Rockbox without actually backing it up but it’s good to know. I read a bit about it but I did become a bit scared through all those warnings – dd can do a lot of harm apparently.
