Well I did a factory reset and it bricked my machine and cannot recover from that. It is flimsy system will never get an Asus machine ever again. It is like if a car wreak because you did not downgrade the gears in the right time.
Re: bricked my tf300t a few days after purchase.
Lucky you. I also tried to do what you described but with no luck. Maybe it needs an hurricane to make it work.
Cheers
