Hi alls, I have my TF101 Wifi rooted with CWM Rogue Recovery and last Revolution HD ROM; I want to return back to stock original Asus firmware removing the recovery and unrooting it.

Download the official firmware from Asus. Flash it with cwm and upon reboot you'll be unroot with stock recovery.

Have I to rename the official firmware in something different?
Can I put it into microSD before flashing?

thanks

No rename just extract the zip file and put it where your recovery can see it.
Boot into recovery (recommend you wipe data, cache and dalvik cache).
Flash it like you would a custom ROM.

Ok but usually when I flash a custom recovery a use the zip file in the recovery without extract it; why have I to extract it now?

Because the official Asus firmware is zipped twice. Once you extract the file you download from the asus site you'll get the flashable zip you can use.
