Something seems off here. Why hasn't the OP mentioned whether or not this was done with or without an unlocked bootloader? I say off, because clearly talk of the town is revolving around how long it is taking to root .21. Balls in your court OP....S/N 10 points to whoever swears on their mothers grave that this works with locked, .21 no root prime. 20 pts if the OP responds first.

Sorry for the late reply!
Yes this does have an unlocked bootloader pulled from my tf201 but I do not know if this can be used to flash over a locked bootloader.
No this will not be able to root .21 but it can install CWM recovery, which would allow you to flash a rooted .21 rom.....
