Follow the instructions precisely and all will be OK! Take your time, don’t rush things and be patient. Only use the ORIGINAL USB Cable, WITHOUT any USB extension cables Make sure your firmware build number is equal to 9.2.1.21 if you have a Transformer TF101 or 9.4.2.21 if you have a Transformer Prime TF201 you are NOT running a custom ROM or have ClockworkMod flashed. Make sure your Transformer’s bootloader is LOCKED, i.e. Make sure your Transformer is NOT Docked Make sure your Transformer is FULLY Charged Last but not least: English is not my first language, so please excuse any spelling errors I’ve made below.

Downgrading and rooting Android devices is highly experimental and may turn your device into worthless brick. I also would like to point out that I am not responsible for any possible damage that this process may cause to your tablet. Just make sure you don’t mix up the firmware numbers. In this tutorial I will be rooting my Transformer Prime TF201, but the process for the Transformer TF101 is exactly the same. If you don’t even know what ‘rooting’ is, then this is not for you! It contains lots of screenshots, which are in Dutch (Nederlands) by the way, but I also assume you have basic computer knowledge. I’ve tried to make this tutorial as easy to follow as possible.
Rooting (and downgrading) is a complicated process. I created this tutorial all by myself after I successfully rooted my Transformer Prime TF201 running 9.4.2.21 and a Transformer TF101 of a friend of mine running 9.2.1.21. This whole process will take about 30 minutes to complete and will keep your data intact. The benefit of this method is that you will not void your warranty, as your bootloader will remain locked.

The only way to root your tablet running 9.2.1.21 or 9.4.2.21 WITHOUT unlocking your bootloader, is to downgrade to an older firmware version, get root, upgrade back to the latest firmware version available and restore our root access using OTA Root Keeper.
