- `if I do a dd to backup from the emmc to an sd card, if I had to do a restore, would a dd from the SD (which should now have the boot loader?) to the emmc be the way to do it?`
I'm not sure if I understood what you mean accurately. As in your previous attempt, there may be some problems with the direct `dd`. Maybe you can try again.
`Alternatively, how would I make a backup image that I could then use RKDevTool to flash onto the emmc (just like how I just loaded the Ubuntu image you provided)?`
