Lenovo doesn't provide updates for the Thinkpad Tablet any more. I'd like to install a custom ROM and therefore need root.

How can I root my Lenovo Thinkpad Tablet?

The method "debugfs automated root" works for the latest official ROM of the Thinkpad Tablet. Like most other root methods, you need to have the Android SDK (or at least adb) installed and must be able to connect adb to your Lenovo Thinkpad (Enable debug mode).

Linux Users

  1. Download the exploit from the XDA Post.
  2. unzip DebugfsRoot_Generic_v2.3.zip
  3. adb push debugfs /data/local/
  4. adb push su /data/local/
  5. adb push debugfsinput /data/local/
  6. adb shell mv /data/local/tmp /data/local/tmp.bak
  7. adb shell ln -s /dev/block/mmcblk0p3 /data/local/tmp
  8. adb reboot
  9. adb shell chmod 777 /data/local/debugfs
  10. Now run the exploit: adb shell "/data/local/debugfs -w /dev/block/mmcblk0p3 < /data/local/debugfsinput"
  11. Cleanup: adb shell rm /data/local/tmp && adb shell mv /data/local/tmp.bak /data/local/tmp
  12. Install superuser: adb install Superuser.apk

Windows

Just run the provided RootDebugfs.bat

  • Is this specific to that device, or kind of Generic for certain Android versions? – Izzy Jan 10 '13 at 15:39
  • I believe that the exploit can be used on other devices too. But I cannot verify this of course. All I can say is that it worked for me with the latest stock version. And this is the situation most people who want to root the TPT are in. – Flow Jan 10 '13 at 15:41
  • Hm, so I might give this a try with my Cat, before I return it due to its display error... Will take a look at the stuff if it does no harm when failing ;) – Izzy Jan 10 '13 at 16:11
  • If you want to use the exploit method on anther device make sure to replace /dev/block/mmcblk0p3 with the correct device node. – Flow Jan 10 '13 at 16:13
  • Good point. Which one is it? I mean, the "target partition" (recovery, system, data...)? – Izzy Jan 10 '13 at 16:19
  • /system (or just follow the steps RootDebugfs.bat does). – Flow Jan 10 '13 at 16:21
  • Could you state specifically the version(s) this works on? – Matthew Read Jan 10 '13 at 16:38
  • At least the latest stock ROM for XEU. But I am pretty sure that it will work on every up to date stock ROM (although I can not verify this, since I only own an XEU device). – Flow Jan 10 '13 at 16:42
  • Tnx @Flow! Will try it ASAP and report back. – Izzy Jan 10 '13 at 20:06
  • Grmpf. /system here is not /dev/... but simply ubi0_0 (UBIFS), so I better don't play with it I guess... – Izzy Jan 10 '13 at 21:12
