Probably not, but the theory between the various approaches is much the same. I read all of them and gave it a shot. What I did not do: patience. I got impatient when it said "waiting for boot" - so I rebooted the device manually. Had I just taken a break, it would have been done in 1 step. Remembering that most everything can be "undone," I then started playing and noted the prompts were not what I was expecting. After a while I then decided to do it the right way and with patience sitting beside me, it was done.

The multiple step method is nice 'cause it forces one to pay attention to the details. The 1-step method requires nothing but following the instructions. If you 1-step, follow the instructions and do not play or be impatient. Impatience and play add extra time.
