If you lost root after updating your Transformer Prime with the latest OTA, we have good news: thanks to a new method found by Android hacker Saurik, you can now root once again.
As always, we're not responsible if you damage your device. It's all you, baby!
So, you ready to make this happen? Let's get started.
First things first, you'll need to grab a couple of files.
Once you've downloaded the required files, plug your Prime into your computer, fire up adb, and enter the following commands (one at a time, of course):
adb push mempodroid /data/local
adb push su /data/local
adb shell chmod 777 /data/local/mempodroid
adb shell /data/local/mempodroid 0xd9ec 0xaf47 mount -o remount,rw '' /system
/data/local/mempodroid 0xd9ec 0xaf47 sh
At this point, you should be in a root shell session (indicated with the pound sign).
