I am trying to reset an intel machine with android 5.0 using fastboot. If I do a complete reset, I have no problem, it encrypts normally & boot & works as a charm. But what I need is to reset the machine while keeping the data, so I removed this command: fastboot format data
After booting the machine I got a screen saying "to start android, enter your password"
whatever last password enetered, I get the folowing (as if the password is wrong) & start resetting the machine..it works well, but no data is there too.
I have no idea to what password does it means nor any of my known passwords work.
