Jump to: navigation, search

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. No one affiliated with the CyanogenMod project is responsible for your actions. Good luck.

Important Notes


The install guide assumes your device is running Android 4.2 or higher. If your device is not at least at this level, you will not be able to use CM until you upgrade. To update your device firmware, click here

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 .
  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 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. Boot to recovery mode, and connect the phone to your computer through USB.
  1. In ClockworkMod Recovery, use the physical volume buttons to move up and down. On most devices, the power button is used to confirm a menu selection, but for some devices a physical home key acts as a selector. Some devices have touch enabled ClockworkMod Recovery, in which case you may be able to swipe to, or touch, menu selections.
  2. Optional (Recommended): Select backup and restore to create a backup of your current ROM.
  3. Select wipe data/factory reset.
  4. You have two options for transferring and installing the installation packages. The sideload method is more universal across devices, whereas the push and install method is more commonly used:
    • Sideload method: select install zip > install zip from sideload. Follow the on-screen notices to install the package. The installer does not necessarily display an "Install complete." message. You can tell the install is complete if there were no fatal error messages and you have regained control over the menu.
    • Push and install method: Open a command prompt (or Terminal on Mac and Linux) and navigate to the directory holding the package(s) you would like to install. On the device, navigate to the mounts and storage menu. If you see /storage/sdcard0 or /sdcard as a mountable volume, go ahead and mount it. If you do not see one of these partitions, then instead mount the /data partition. Take note of which volume you mounted. Now, push the package(s) to your device (also, see tip below):
    - If you mounted /storage/sdcard0, then: adb push /storage/sdcard0/
    - If you mounted /sdcard or /data, then: adb push /sdcard/
    where should be replaced with the package filename. Go back to the main menu and select install zip. Choose to install from the same directory where you pushed the package(s). If you are installing multiple packages, install CyanogenMod first and then install any subsequent packages on top of it.
  5. Once installation has finished, return to the main menu and select reboot system now. The device will now boot into CyanogenMod.

Helpful Tip– SD card folders

CyanogenMod 10.1 and newer have multi-user support (introduced in Android 4.2). If your device has storage on the /data partition, then Android actually looks in /data/media/0/ for the first user's /sdcard/ storage. ClockworkMod recovery symlinks /sdcard/ to /data/media/ though. So, if you are pushing files to internal storage in recovery and want them to be visible in Android, you should push them to /sdcard/0/ or /data/media/0/. Here's the most frequent scenarios:

  1. If you're coming from a ROM with Android 4.1 or older to CyanogenMod 10 or older: adb push /sdcard/
  2. If you're coming from a ROM with Android 4.1 or older to CyanogenMod 10.1 or newer: adb shell "mkdir /sdcard/0/" followed by adb push /sdcard/0/
  3. If you're coming from a ROM with Android 4.2 or newer to CyanogenMod 10.1 or newer: adb push /sdcard/0/
