Asus Unlock Tool:

Get TWRP for TF201Jellybean:

TWRP Page

On that page are instructions including a download link for

JB BOOTLOADER ONLY! MAKE SURE YOU GET THE RIGHT TWRP FILE FOR YOUR DEVICE. THE ICS ONE IF YOU ARE ON ICS, OR THE JB ONE IF YOU ARE ON JB:

I got ADB from several sources but this "root method" http://xdaforums.com/showthread.php?t=1886460 from bin4ry is what I have been using: (And no, it doesnt work for the prime because the exploit he uses to run the device in emulator mode doesnt work for us)

Download bin4ry's root tool to get the ADB file

When that is downloaded you can compare the MD5 hash because its a good idea to do that. You can find something like winMD 5 generator:

http://www.winmd5.com/download/winmd5free.zip

Use it to generate an MD5 hash of the TWRP download to what it saysthe files MD5 hash is on the download web page. If I remember correctly I had to manually type in the MD5 hash from the page because it was an image I couldnt just copy. Or you can just visually verify with the one generated by winmd5.

Then I downloaded Ultimate Backup Tool from here:

http://goo.gl/iOUwe

Unzip it so you have fastboot.exe

Rename the TWRP you downloaded to TWRP.blob and copy it to where you have fastboot unzipped.

Finally download SuperSU zip file from:

http://downloads.noshufou.netdna-cdn.com/superuser/Superuser-3.1.3-arm-signed.zip

Now we need to unlock the device. Copy the unlocker APK to the SD card. Run a file explorer on our tables and browse to the SD card (/Removable/MicroSD). Tap the APK to install. Once installed run the Icon for the unlocker and follow directions. There are several warnings etc.. You will need wifi connected and it will unlock your device and VOID YOUR WARRANTY!.

The unlock will take a few minutes. When it is successfull you will see a notice on device boot up that says the device is unlocked.

Once unlocked, power it off. Once off power it onby holding BOTH volume down and power buttons. When you see the menu appear the first option is RCK. press Volume Down to change the cursor to be over the USB logo (two presses of the button) and press volume up. This puts your device in fastboot mode

Back on your computer you should hopefully see a successfull driver install. I got drivers from downloading and installing the Android SDK so you may or may not need to do that. Android SDK

If all is prepared and you are in fastboot with drivers loaded:

On your computer hold shift and

right

click on the folder where fastboot and the twrp.blob file are and you will see a context menu. Click on "Open Command Window Here"

if you don't get the command window here option then you will have to open a command prompt. open the run dialog and type CMD and hit enter. This will get a dos command windows. Use the change directory (CD) command to change the current folder in the DOS window to where your fastboot file and TWRP.blob are.

In the command window paste:

fastboot -i 0x0b05 flash recovery twrp.blob

and hit enter

Let it runs its course. When done I had a black screen with ASUS in the middle and a blue-ish bar across the bottom that was filled. I had to hold power until it rebooted.

Once I confirmed my Stock OS loaded I copied the Super SU zip file we downloaded above over to the device via the USB cable to the root of my SD card. Once the copy complets shutdown the device again.

Once off, power it on and press and hold both the power buttons and volume down again. When the menu appears you should already have RCK (recovery) hightlighted so press volume up to load TWRP recovery.

Once TWRP loads the top left option is "Install" tap that.

You will see a few choices, select the radio button to install from SD card (external source it may say). Tap the super su zip file: Superuser-3.1.3-arm-signed.zip to choose it.

Slide the slider at the bottom to the right.

This will flash superSU to your device. When done, reboot (should only take a few seconds).

When you boot up SuperSU is installed.

To test root with ADB:

Your tab must be plugged in to the USB port of the computer of course.

If you installed the SDK tools it is there or use the one from bin4ry's root tool as follows:

Unzip the downloaded root tool from bin4ry mentioned above. Use the command windows to change directory of the unzipped folder and further in to the "STUFF" folder. type:

adb shell

<hit enter>

after a few seconds you should see a $ prompt and your are in to the console of your tablet.

Type:

su root

<hit enter>

Superuser will prompt you to grant root permissions and I set the setting so it doesnt prompt me every time.

Your prompt will change to # and thats it, you are root.

I don't seem to have the command sudo on my tab so every time in a terminal I want root I will type that su root to get the # prompt.

Any apps that need root can now ask for it, you will get that same "Grant" prompt and do so if that is what you want.

ADB will now yield Root when you type: SU root and hit enter (grant root privs in the popup)etc...

I have editted this based on questions below to make it more complete..
