This guide will walk you through the process of taking the Transformer Pad from stock to having a custom recovery image and the ability to flash the latest version of CyanogenMod.

Modifying or replacing your device's software may void your device's warranty, lead to data loss, hair loss, financial loss, privacy loss, security breaches, or other damage, and therefore must be done entirely at your own risk.

Unlock and Install a Custom Recovery on the Transformer Pad

Obtaining the Bootloader Unlock Application

If the Bootloader on the Transformer Pad has already been unlocked, you may skip this section.

  1. Configure your computer for ADB and fastboot.
  2. Navigate to Asus' support site for the Transformer Pad.
  3. From the drop-down menu, select Android.
  4. Expand the section titled Utilities.
  5. Download the file named Unlock Device App (V8). If the downloaded file is packaged in a rar archive, extract it.
  6. Open a command prompt or terminal to the location where Unlock_v8.apk resides .
  7. Install the APK using adb:
    adb install Unlock_v8.apk
  8. Run the application "Unlock Device Tool" from the tablet and agree to the terms.
    Note 1: if you have two-factor authentication enabled on your Google account, you will have to generate an individual app password on the Google accounts settings website, as the ASUS unlock app does not natively support two-factor.
    Note 2: After you agree with the terms, the Asus unlock app will ask you to login with your gmail account. If your password does not works, then you need to enable temporary access for less secure apps at https://www.google.com/settings/security/lesssecureapps .
  9. Reboot the device.

Installing recovery using fastboot

You can use fastboot to install your recovery image to the device.

Installing recovery on the Transformer Pad

  1. Download recovery -- you can directly download the recovery image using the link below, or visit clockworkmod.com/rommanager to check for the latest version of ClockworkMod (if your device can be found there). Be careful to select the right image!
  2. Connect the Transformer Pad to the computer via USB.
  3. Make sure the fastboot binary is in your PATH or that you place the downloaded image in the same directory as fastboot.
  4. Open a terminal on your PC and reboot the device into fastboot mode by typing adb reboot bootloader or by using the hardware key combination.
    If your stock ROM is a Jellybean release, this should drop you into fastboot mode. If your stock ROM is an ICS release, you will likely need to use the Vol Down key to highlight fastboot from a boot menu and then and press Power to select it.
  5. Once the device is in fastboot mode, verify your PC sees the device by typing fastboot devices
    • If you don't see your device serial number, and instead see "<waiting for device>", fastboot is not configured properly on your machine. See fastboot documentation for more info.
    • If you see "no permissions fastboot", make sure your UDEV rules are setup correctly.
  6. Flash recovery onto your device by entering the following command: fastboot -i 0xb05 flash recovery your_recovery_image.img where the latter part is the name of the file you downloaded.
  7. Once the flash completes successfully, reboot the device into recovery to verify the installation.
    • Note: Some ROMs overwrite recovery at boot time so if you do not plan to immediately boot into recovery to install CyanogenMod, please be aware that this may overwrite your custom recovery with the stock one.

The Transformer Pad should now be ready to install Cyanogenmod.

Installing CyanogenMod from recovery

  1. Make sure your computer has working adb.
  2. Download the CyanogenMod package for your device that you'd like to install to your computer.
    Optional: Download 3rd party applications packages, like Google Apps which are necessary to download apps from Google Play.
  3. Place the CyanogenMod .zip package, as well as any optional .zip packages, on the root of /sdcard:
    • Using adb: adb push filename.zip /sdcard/
    Note: You can copy the .zip packages to your device using any method you are familiar with. The adb method is used here because it is universal across all devices and works in both Android and recovery mode. If you are in recovery mode, you may need to ensure /sdcard (sometimes called Internal Storage) is mounted by checking its status in the Mounts menu. If you have booted regularly, USB debugging must be enabled.
  4. If you are not already in recovery, boot to recovery mode now.
  5. In Team Win Recovery Project, select menu choices by tapping on the appropriately labelled button.
  6. Optional (Recommended): Select the Backup button.
  7. Select Wipe and then Factory Reset.
  8. Select Install.
  9. Navigate to /sdcard and select the CyanogenMod .zip package.
  10. Follow the on-screen notices to install the package.
  11. Optional: Install any additional packages you wish using the same method (if you are installing multiple packages, install CyanogenMod the first and then install any subsequent packages on top of it).
  12. Once installation has finished, return to the main menu and select Reboot, then System. The device will now boot into CyanogenMod.
