Anything can be a butt plug if you are brave enough
My 1st android device would be 2nd hand xperia x10, i remembered installing cyanogenmod 7 on it and learning about rooting through it
Hey i too used to have the same device, altough not the 1st one
The same thing can be seen on some MIUI device that i used before. Need to quickly press the recovery keys combination to enter TWRP. Entering recovery command from terminal would directly boot into OS.
