[Thinkpad Tablet General] AndroMAN:
Hi?

I'm posting this thread for all those who want to root their tablet but need a step by step guide for the same. I have condensed the information from many threads and put it into one. All the credit goes to the respective thread owners who have posted the guides. Let's begin:

NOTE: Im not responsible if you brick your device. You are solely responsible for what happens. If you follow the steps correctly it is unlikely that it will harm your device. If you face any issues you can post it here and I will try to solve them ( or someone else will). All good.

Scary stuff apart, let's begin to root your device ?

1. On your device, Go to Settings, Developer Options, and click on Enable USB Debugging. If there is no Developer Options in Settings, Click on About Phone and click 7 times on Build Number. This will give u the option.

2. Once you have enabled it, connect your device to your computer via USB cable.

3. Install the device drivers from the autoplay options.

4. Right click on My Computer and click on Manage

5. A new window will open called Computer Management, under which u have to click on Device Manager.

6. A list of devices connected to your computer will be shown on the right hand side.

If your device is listed under heading Android, as Android ADB Composite Device, then there is no need to download and install adb/fastboot drivers, and you can go ahead with the rooting process.

But its most likely your device will be listed under Other Devices. Under that it will be as MTP device or by the name of your device itself. This means you have to download and install adb/fastboot drivers on your computer before rooting it.

7. Open your browser and click on http://adbdriver.com/upload/adbdriver.zip which will download the adb installer on your computer. Run through the setup and install it. Run the program, it will automatically detect your device and install the necessary adb/fastboot drivers for it on your computer.

Alternatively, you can click on http://xdaforums.com/showthread.php?p=48915118 through which you can install the same. I did it with the first method for my device.

Download and install it in [C drive].

8. Once the drivers are installed, go to Device Manager again (Step 4 and 5), and check on the list of devices. Your device should be listed under the heading Android, and showing as Android ADB Composite Device.

9. Open up C drive, there should be a folder named 'adb' under it. Open that folder and right click anywhere and open a command prompt.

U can also press 'Win+R' keyboard keys and type in 'cmd.exe' to open up a command prompt and use the cd command to come into the right folder. Once your into the adb folder in the command prompt (it should show as "C://adb>".

Type in command 'adb devices' and press enter (without the colons).

This should show you that your device is connected by the name of your chipset as Baytrail******. If it doesn't show this it means the adb drivers are not installed or ur device is not connected to the computer. Only once after it detects your device you have to go ahead with your rooting process.

10. After you have successfully completed all the above steps you are now ready to root your device.

11. Click on this link xdaforums.com/showpost.php?p=57543871&postcount=1 from where you will have to download 'Intel Fastboot Tethered Temporary Recovery Session Launcher' onto your computer and extract it to some folder.

12. Download the UPDATE SuperSU zip file to your device and store it in your internal memory so you can find it easily later.

13. Now open the folder where you have extracted the Intel Fastboot Tethred Temporary Recovery Session launcher. Double click the launcher.bat file to start and type " ACCEPT " case sensitive without quotes to continue.

check that the tool is reporting as either :

DEVICE STATUS: ADB-ONLINE

DEVICE STATUS: FASTBOOT-ONLINE*

If " DEVICE STATUS: UNKNOWN " please check your cable connection and driver installation under Windows Device Manager

If " DEVICE STATUS: UNAUTHORIZED "

Please check if your devices is displaying an authorization prompt.

Be sure to check 'Always allow from this computer' and then press ok.

It will ask for the type of recovery u would prefer to run. Options 1-4 will be TWRP recovery and 5 will be CWM. I selected the CWM recovery. So enter number '5' and press enter.

14. It will display the list of triggers to be selected for the rooting process. Select the trigger to launch the Temporary CWM Recovery Session.

The list will be as follows:

T1 oem startftm ( very few devices support this command , but its the original used so )

T2 oem backup_factory ( limited devices support this command )

T3 oem stop_partitioning ( should work on alot of kitkat builds )

T4 oem stop_partitioning ( probably works on all devices that are supported (Jellybean , KitKat , Lollipop)

15. Select trigger 'T4' if you have upgraded your tablet to Lollypop Android 5.0.1. After selecting the trigger your device should reboot into fastboot and begin to copy files to your device.

note :*If your device hangs at the waiting-for-device screen and you see droidboot CMD Waiting on your devices double check that the fastboot driver installed correctly.

note :*If you see unknown oem command the trigger isn't supported by your device.

16. The temporary cwm recovery session will start at this point on your device.

17. Select install zip from the recovery menu using vol up / vol down to navigate and power to select.

18. Select install zip from sdcard / external_sd depending on where you placed the file and select the UPDATE-SuperSU-vX.Xx.zip you downloaded earlier

19. Confirm the installation.

20. After install completes reboot your device*through the reboot device option in the recovery menu itself.

21. It's going to take a while for the device to reboot. 'Android is upgrading' window will pop up once the screen gets on. After the boot is complete open all apps to see Super SU installed in it.

Now you have successfully rooted your Yoga Tablet 2. Enjoy ☺

NOTE: Follow all steps carefully and correctly so it becomes highly unlikely that you may brick your device. Make sure there is no powercut to your computer during the rooting process if you are not using a laptop or a UPS for your system. You can post any queries or questions in the thread.
