Thanks Daivd, I did a bit of a search but was unable to find information about Aura boot from SD... Any tips? I have another unit I am about to start modding and would like to be able to restore it with the fresh image I just made of the internal flash mem.

If i am correct this should work? I will just replace the Android image with my backup or modified image? This way I could dual boot to the internal flash (unmodified original Kobo OS) or my modified XCsoar OS?
