How to root ThinkPad Tablet Step by Step

Default OS for ThinkPad Tablet is Android 3.1. Like the Blackberry Playbook, users are not allowed to use Google Play.  So we need to get root access for ThinkPad Tablet to get freedom to install Google Play or other great Android apps. Now let’s rooting Lenovo ThinkPad Tablet step by step: ( Some one click rooting tutorial may not work for newest version TinkPad.)


  • Make sure you know the risk to root ThinkPad Tablet.  Any loss should be undertaken by yourselves.
  • This tutorial is conducted under Windows 7 64bit system.

Rooting Preparation

1) Prepare a storage card

ThinkPad Tablet has a three-in-one card reader slot.  You must have an storage card and make sure it has more than 6MB free space. I uses mini MMC in this tutorial.

2) Download firmware with rooting bug

Download the firmware which has a bug for rooting from here. If you uses non-English version, you can find firmwares here: No matter which ThinkPad Tablet model you are using, this firmware will be OK. (Android 4.0 may can not use this file.)

Just copy the zip file to your Storage Card root folder. DO NOT UNZIP THIS FILE. Then put the Storage Card into your ThinkPad Tablet.

3) Download root patch.

Get the ROOT file from Unzip it to you PC. You will get the folder called “yareftpt”.

4) Enable USB debugging on your ThinkPad Table

Go to Settings->Applications->Development and Check the box for USB debugging.

5) Install the latest Lenovo ADB driver on your PC.

a) Download ADB driver from Lenovo.

b) Install it by following steps below:

i) make sure enabled USB debug mode and connect your ThinkPad Tablet to PC.
ii) open Device Manager on your PC.
iii) find the ThinkPad Tablet under “other devices” and right click it. update driver to the ADB driver from Lenovo.
v) then you will see the Android Phone device under Device Manager list.

If you can not see the device, you should skip this step and jump to step 6.

6)Enter Recovery mode

a) Keep USB connecting and close the ThinkPad Tablet.

b) Restart tablet. Click volume up few times when you see white Lenovo logo. And you will be led to Recovery mode. You will see this interface: ( DON’T MAKE ANY OPERATION ON THINKPAD TABLET NOW) 

Start rooting

This seems some complicated. But it is actually very easy if you can follow my steps. You are suggested to copy and paste following commands to command window.

1) Run a command window on your PC

Find the yareftpt file you have just downloaded. Press “Shift” and right click on the yareftpt folder. Select “Open Command window here”. Then you can use Linux command to operate ThinkPad Tablet.

  • Do not copy more than 1 row once
  • Press “Enter” after inputted 1 row. Make sure there are no error alert like no device or not found. Then continue.
  • If you see a alert, it should be some steps you did wrong. If you see a “no device” error, you must go back to install the ADB driver.
adb shell "/system/bin/mkdir /data/local/pwn"
adb shell "/system/bin/mkdir /data/local/pwn-bak"
adb shell "/system/bin/cat /system/etc/ > /data/local/pwn-bak/"
adb shell "/system/bin/mkdir /cache/recovery/pwn"
adb push su /cache/recovery/pwn

adb shell "echo \"/system/bin/chmod 777 /cache\" >> /tmp/recovery.log"
adb shell "echo \"/system/bin/mount -t ext4 /dev/block/mmcblk0p4 /cache\" >> /tmp/recovery.log"
adb shell "echo \"/system/bin/chmod 777 /cache\" >> /tmp/recovery.log"
adb shell "echo \"/system/bin/mount -oremount,rw -t ext4 /dev/block/mmcblk0p4 /cache\" >> /tmp/recovery.log"
adb shell "echo \"/system/bin/chmod 777 /cache\" >> /tmp/recovery.log"
adb shell "echo \"/system/bin/chmod 777 /cache/recovery\" >> /tmp/recovery.log"

adb push /data/local/pwn/
adb shell "/system/bin/chmod 777 /data/local/pwn/"

Continue with the following command:

adb shell

When the “$” turns to “#”, it means you get a temporary root authority.

Continue following commands:

/system/bin/mount -oremount,rw /system
cat /system/xbin/su > /data/local/pwn-bak/xbin-su
