After much waiting, the Lenovo Thinkpad Tablet has finally been rooted.
The exploit was discovered by Dan Rosenberg officially known throughout the development community and twitter handle as djrbliss.
The full root process can be found on his blog here
. Additional info can be found here
I am providing a copy of the instructions below. There is a bounty that was set up in the ThinkPadTablet forums and any donations should be made through djrblis's blog.
1. Make sure you have the latest ADB drivers installed on your PC, and that your device is in USB Debugging mode. More detailed instructions for this are available here
2. Download the root exploit here
3. Make sure your Thinkpad is connected to your PC via USB, is turned on, and has the screen unlocked.
4. Extract the entire zipfile, and run “run.bat”. Follow any directions given in the command prompt closely, and ignore any activity on the Thinkpad itself.
In case you need to unroot for any reason such as returning the device to Lenovo for warranty work, these are the steps..
1-Follow instructions to set up ADB (should already be set up since you rooted previously).
2-Run "adb shell" from a command prompt.
3-In the ADB shell, type the following commands:
(this will cause a prompt to come up on the phone asking you to grant root permissions, accept this)
Then, back in ADB shell:
mount -o rw,remount /dev/block/system /system
Then you can exit and you're unrooted.
