The Asus Eee Pad Transformer was one of the mean machines that disrupted the tablets market and opened many consumers' minds to various other possibilities for Android tablets.   The Transformer is the predecessor of the quad-core Eee Pad Transformer Prime and was the device that started the Transformer legacy.  Many were delighted by the tablet's great style and functionality–it's a notebook and a tablet fused together, a transformer.

What's making people more excited is the prospect of being able to load it up with Android 4.0 Ice Cream Sandwich. Now that would make this a tough device on the outside with sweet ICS filling on the inside.

To be able to load ICS-based custom ROMs to your Asus Transformer, you will need to root it.  In this guide, we will walk you through the steps in rooting your Asus Transformer with the use of NachoRoot, a tool that can root the Asus Transformer regardless of whatever firmware is running on the tablet.  Once you've rooted your Asus Transformer, you can now flash custom ROMS–including those based on Ice Cream Sandwich–to your tablet.

Requirements

To root your Asus Eee Pad Transformer using the instructions in this guide, you will need to have the Android Debug Bridge (ADB) installed on your computer. Once you have ADB on your computer, you can proceed to the installation instructions below.

Installation Instructions

NOTE: Use these instructions at your own risk. We will not be held responsible if you damage your phone by following this guide.

1. Download NachoRoot from here and the su binary from here. Save both files into the same folder where adb is located on your computer (usually inside the /platform-tools or /tools folder inside the Android SDK installation folder).
2. Enable USB debugging on your device from Settings > Applications > Development.
3. Connect your Eee Pad Transformer to your PC.
4. Open a command prompt on your computer.
5. Go to the ADB directory on your computer and enter the following commands as listed below (it is necessary that they are entered in this order):
• adb push nachoroot.bin /data/local/
• adb shell chmod 777 /data/local/nachoroot.bin
• adb shell /data/local/nachoroot.bin –stage1
• adb reboot
6. Wait for your device to boot and after it has booted, enter the following commands at the command prompt:
• adb shell /data/local/nachoroot.bin –stage2
• adb reboot
7. After that, you have to wait for your device to boot again and enter this command:
• adb shell id
8. If the result is from the command in the last step is not 0, repeat entering the adb commands from the top until the result of “adb shell id” is already 0.  Only then should you proceed to the next step.
9. Enter the following commands at the command prompt:
• adb remount
• adb push su /system/xbin/su
• adb shell chown 0.0 /system/xbin/su
