i'm just curious if this really works as i understood (and also seems quite logical) that one can't write data to a mounted partition or at least to a mounted partition that is in use (by e.g. executing some program). so if i recall correctly the boot-partition that provides some form of recovery environment (e.g. busybox) is part of /dev/block/mmcblk0 and therefore would also be overwritten, right?
i could imagine this may work in quite some cases as once busybox runs nc and dd all thats needed is loaded into the devices memory but i'm not sure i'd rely on this always working successfully.
therefore restoring single partitions sounds much safer to me but i'm happy to hear about differing experiences.
if i understood correctly, alexs77 had success with this, right alex?
