Getting an update often requires a new root method. As new versions of the firmware are released, old root methods are sometimes patched off. It’s then set upon developers to find a new root method. In some cases, it can be rather hard. Other times, users and developers luck out and root methods for other devices help out. For the Lenovo Thinkpad Tablet, the latter is the case.
XDA Senior Member emuandco took a risk and started trying root methods from other devices to see if one of them would work. As luck would have it, one happened to work. The Transformer Prime Debugfs Root method by XDA Recognized Contributor sparkym3 successfully rooted the Lenovo Thinkpad Tablet.
In case you haven’t seen it, the Debugfs Auto Root tool is an automated root script. Users just need to download and run the script. Of course there is the risk of things going wrong, but that is always the case with device hacking. In terms of compatibility, users have reported that Lenovo users don’t have to do anything differently than the Transformer Prime. So simply follow the instructions as they’re written.
