But I don't think there *is* a secret partition - just the area occupied 
by the working system, which gets over-written by upgrades.

If there "were" a secret partition, there would be no need to over-write 
it and you truly would be able to go back to "factory" conditions. But 
think of the cost. On a phone like mine - with only 8GB total memory - 
you'd need an extra 3 or 4GB to hold the virgin copy of the OS. Do you 
*really* think they'd do that?

[PCs have hidden 'restore' partitions because disk storage is cheap and 
they only represent a small proportion of the total disk space, but 
phones and tablets - with a relatively small amount of expensive solid 
state storage - are different.]
