Have you just grabbed the latest official OTA update by Asus for your Eee Pad Transformer Prime? This update, the ICS 9.4.2.11 firmware, disables root access on your Asus Eee Pad Transformer Prime.

If you’ve already got the ICS 9.4.2.11 firmware running on your device, however, there’s no need to panic. You can still regain root access on your tablet, and all in one click.

Thanks to XDA-Developers member -viperboy-, viperMOD Prime Time has been updated to work on the ICS 9.2.4.11 firmware. viperMOD Prime Time is an automated rooting program that comes with extra features that other root tools don’t have and it is extremely simple to use. Even the most novice of users can figure their way around it. In fact, it’s as simple as hooking your device up to your computer, running a program, and pressing one key. You read that right.

Requirements

Eager to get your root access back? Before we begin with the rooting process, you’ll need a few things:

• The viperMOD Prime Time one-click root tool.  Download the tool for Windows or for Linux.
• Ensure that USB Debugging has been enabled on your tablet. You can do this through Settings > Developer Options.
• Ensure that your tablet has a charge of at least 70%, to prevent it from shutting off in the middle of the rooting process.

Step-by-step Guide

Once you have everything required, you may now proceed to the rooting process:

1. Begin by downloading the viperMod Prime Time root tool onto your computer.
2. Extract the contents of the viperMod Prime Time root tool ZIP file.
3. Kill Asus Sync and Splashtop.
4. Connect your tablet to the computer.
5. Make sure you install the device drivers located inside of the ZIP file. (If you can already adb into your device, then you do not need to install the drivers.)
6. If you are on Linux, you  may need to do “chmod a+x /path/to/primetime/primetime.sh” (without the quotes).
7. Run PrimeTime.exe. You will see a command line prompt.  (On Linux, run the “primetime.sh” script.)
8. Type 1 to start rooting your device.
9. Once you’re done, install the OTA Root Keeper from the Android Market.

Congratulations! You’ve now regained root access on your Asus Eee Pad Transformer Prime after updating the tablet with the ICS 9.4.2.11 firmware OTA update. With the help of OTA Root Keeper, you’ll have a backup of your device’s root and will allow your root to survive OTAs, if several conditions are matched. You should only download the OTA Root Keeper after your Asus Eee Pad Transformer Prime has been successfully rooted.
