[Eee Pad Transformer Q&A, Help & Troubleshooting] frederuco:
First thing - Does your tablet get seen by your PC in either APX or ADB mode? And did you update the driver using the Naked Drivers?

Last time I rooted I used Wolf's Method 3. Here is what I did:

Plugged in my tablet to my PC via USB (win 7 PC).

After the device was detected, I went to Settings - Developer Options - Debugging (tick the box).

It should install new hardware and show 2 devices, an MTP and an ADB device.

Update the driver in the Device Manager on the windows machine to the Naked Drivers

Once that is updated, I downloaded ADB from the Android SDK. You really only need three files, available here: http://xdaforums.com/showthread.php?t=1998650

Unzip these files to a folder called c:\adb

Open a command prompt and type the following:

c:
cd c:\adb
adb devices

It should show a device connected. It may error out when restarting the daemon, but keep trying and see if it can find your tablet.

If you cannot get the ADB driver installed or updated, my guess is that you have a bad USB cable. Yes, it IS possible to have a bad cable for data transfer that STILL charges your tablet. I have even had that happen to me.

If you got this far, then here is what to do next:

Download your favorite recovery. I strongly recommend TWRP. The latest official release is here: http://techerrata.com/file/twrp2/tf101/openrecovery-twrp-2.3.2.3-tf101.blob

Save this at c:\adb\TWRP.blob. You can use a different recovery method if you have the blob file (such as CWM) but TWRP is far superior unless you are looking to install Android Revolution HD.

Next, run the following commands (from Wolf's Exploit, Method 3)

adb push TWRP.blob /sdcard/
adb shell
mv /data/local/tmp /data/local/tmp.bak
ln -s /dev/block/mmcblk0p4 /data/local/tmp
adb reboot
exit

It will reboot. Once you see the ASUS loading screen, you can continue:

adb shell
dd if=/sdcard/TWRP.blob of=/dev/block/mmcblk0p4

Wait until you see it succesfully transfer data.

Then:

adb reboot
exit

Once it reboots, you should see a progress bar at the ASUS screen. Once this completes you will have TWRP (or some other custom recovery installed)

Now you can install your favorite SuperUser app.

Download a zip flashable SuperUser

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

ClockWorkMod SuperUser: http://download.clockworkmod.com/superuser/superuser.zip

Chainfire SuperSU: http://download.chainfire.eu/333/SuperSU/UPDATE-SuperSU-v1.34.zip

I like the CWM SuperUser at the moment, but all three will work.

Put these where you can see them from the recovery you flashed. If using TWRP, it needs to be in the /sdcard/ directory or on the microSD card.

Next, reboot to recovery. Hold VOL DOWN and POWER for 12-15 seconds until you see some white text in the upper left of the screen. Release both buttons and tap VOL UP to enter RCK (Recovery).

Once in recovery, tap Install and choose the SuperUser.zip file to install. Once installed, you are rooted.

Another time I rooted, I used EasyFlasher and here is the thread on my rooting guide for that if you are interested: http://www.transformerforums.com/fo...nt/31927-frederucos-guide-root-rom-tf101.html

Once again, if you cannot get your tablet detected by ADB or APX, chances are it is a bad USB cable.
