Yet Another Root Exploit For Thinkpad Tablet … more on the way UPDATED

Works with Honeycomb (Android 3) only. If you’ve upgraded to ICS, you have to wait. Sorry!

UPDATED TO WORKAROUND THE ro.kernel.qemu MODE REMOVAL FROM ADBD
UPDATE 2: If rooting fails: do this

Common instructions:

  1. Go to http://download.lenovo.com/slates/think/tablet1/ and download the OLDEST update (currently: tablet1/ThinkPadTablet_A310_02_0024_0060_US.zip)
  2. Put it on SD card and plug the SD card in the tablet
  3. On the tablet enable USB Debugging: [Settings->Applications->Developmnet->USB Debugging]
  4. Download the root script package here
  5. unpacking yareftpt2.zip will create directory: yareftpt
  6. (Windows only)If the lenovo driver is not installed on your PC, install it : http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS022366
  7. (Linux Only)Make sure adb is in your PATH
  8. Connect the tablet to the PC (USB)
  9. Make sure you know how to boot the tablet in Recovery mode:
    – Shutdown, then start it, in the moment “LENOVO” image appears on the screen, press “Volume Up” few times
    – You can navigate through the menu with the volume buttons, and select option with the power button
    – If everything ok, just reboot in normal mode
  10. on the PC, go to command line, and navigate to that directory where you’ve unpacked the exploit download.

Windows instructions:

  1. On command line execute: run.bat
  2. Follow on-screen instructions

Linux instructions:

  1. execute ./run.sh
  2. Follow the on screen instructions




If rooting failed, do not retry immediately:
First reinstall your CURRENT update,
enable USB debugging
finally, redo the whole rooting procedure (including: Installation of VERY OLD update)
Ack: thanks to Driver’z on xda for
discovering it

Ack: thanks to @djrbliss, without his tpt exploit this one would not be possible.

    Yay! Root works with 0089_ROW (OTA 2.5) The issue was with the bootloader USB drivers. I did a factory reset, but that was unnecessary in my view.
    Do make sure you have the right drivers and lines in the
    android_winusb.inf file:
    Code:
    [Google.NTamd64]
    ;
    ;NVIDIATegra
    %SingleAdbInterface% = USB_Install, USB\VID_0955&PID_7000
    %CompositeAdbInterface% = USB_Install, USB\VID_0955&PID_7100&MI_01
    ;
    ;NVIDIA Tegra %SingleAdbInterface% = USB_Install, USB\VID_17EF&PID_741C
    %CompositeAdbInterface% = USB_Install, USB\VID_17EF&PID_741C&MI_01
    ;
    ;Lenovo Think Tablet
    ;%CompositeAdbInterface% = USB_Install, USB\VID_17EF&PID_741B&MI_01
    ;%CompositeAdbInterface% = USB_Install, USB\VID_17EF&PID_741C&MI_01
    ;%CompositeAdbInterface% = USB_Install, USB\VID_17EF&PID_741D&MI_02
    ;%CompositeAdbInterface% = USB_Install, USB\VID_17EF&PID_741E&MI_02
    The script does work. So now I have 0089_ROW with root.

    @Stewart Adam: How dude!? I am trying but no luck!

    Hi,

    I’m sorry to report that this didn’t work for me. I have just bought my TPT and have not applied any OTA. Buildnumber is ThinkPadTablet_A310_02_0039_0089_US.

    The only clearly suspicious parts are the
    * expected failed update from external storage. I get an error about “assert failed” and my windows 7 starts trying to install some drivers but failed.
    * After following “When wipe cache complete, press .” I got some “mkdir failed for …, file exists”

    Then, after the reboot, I only get an “The system update failed. Please try again. Version: ThinkpadTablet_A310_02_0039_0089_US” message on the tablet, and /cache/recovery/pwn/su on “adb shell” gives me permission denied.

    Any help would be greatly appreciated!

    I had to do the double-up method, but it worked a dream. Thank you, thank you, thank you!

  9. Aleksey says:

    go to recovery (do not run.sh or run.bat). While in recovery (after “installing” the failing update AND wiping out cache partition), do
    adb shell
    when you get the shell prompt ($)
    /system/bin/mount

    ADB shell log:
    $ /system/bin/mount
    /system/bin/mount
    /system/bin/mount: not found
