I recently purchased a 4GB SDcard to house a 4GB IMG file for my AndroidTV system recovery & firmware upgrades, but it's just a teensey bit too small and I am needing help please:

In windoze the instructions to setup the firmware/restore image require a raw copy and recommending the use of the win platform tool "HDD Raw Copy". There doesn't appear to be an equivalent GUI app for nix platforms and searches at all the usual linux help sites are only giving me raw copy methods using the "dd" command which I confess to being somewhat phobic about.

I successfully raw copied the IMG to a larger SDcard I have here as a temporary measure to unbrick my AndroidTV device, but I need that for another purpose and am revisiting the possibility of successful raw copy to the 4GB SDcard after reading somewhere that it is actually possible to compress the IMG to make it fit.

I should clarify that, once raw copied to an SDcard, the actual contents of the IMG are only about 100Mb so what I am needing help with is to find a linux-based method to get these raw copied without effecting the bootability of the SDcard on my AndroidTV device.

Sorry if my explanation is a bit vague due to not knowing the correct technical terms to communicate what I am trying to achieve.

Thanks in advance for any suggestions that do not say "buy a bigger SDcard" Wink

I usually use the dd command, but yes it can be destructive if you give it the wrong device :)

I've also used UNetbootin in the past, and I think this will do what you want. From memory it hides devices/partitions that it thinks you probably don't want to overwrite and shows your sd cards/usb drives.

Actually that might just be for making bootable usb drives... probably not what you're after but might do the job?

Good luck!

Thanks Ewen, that was the first app I tried, but without success.

I wish I had bookmarked the forum page where I saw the method to compress the IMG file first, but hindsight is, well... yanno (((shrug)))

From what I do remember, it looked like a two-stage process which required an editing of the IMG file first and the second step being a "dd" copy. In windoze I think I may have been able to use an ISO/IMG mastering app like UltraISO.

I did actually resort to installing wine to see if I could get away with using the portable version of HDD Raw Copy, but not a lotta luck there either.

Probably I would have better luck with the help sites if I know the correct technical terms to search by.
