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 Asus Transformer Pad TF300T is a touchscreen tablet manufactured by Asus. Official CyanogenMod support for the Asus Transformer was added in CyanogenMod 9.0. Warning: Asus is in a habit of breaking bootloader compatibility between versions of the stock firmware. Current builds of CM10 are compatible with the bootloader included in Asus firmware releases of Android 4.1. Check the forums for details.

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. You will need the Android SDK on the computer to install this application.
  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 (V7) and save it in the SDK folder with adb.
  6. Install the APK using adb from the terminal:
    adb install UnLock_Device_App_V7.apk
  7. Run the application from the tablet and agree to the terms.
  8. Reboot the device.

Flash a Custom Recovery

  1. Download koush's ClockworkMod Recovery. You can directly download the recovery image using the link below, or visit to check for the latest version (if your device can be found there). Be careful to select the right image!
  2. Make sure the fastboot binary is in your PATH or that you place the downloaded image in the same directory as fastboot.
  3. 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.
  4. Use Vol Down to highlight fastboot mode and use 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.
  6. Flash ClockworkMod 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 can clobber your custom recovery.

The Transformer Pad should now be ready to install Cyanogenmod.

Installing CyanogenMod from recovery


Some devices do not have removable SD cards. Regardless, there should still be a partition on the device named "/sdcard" that can be used for flashing purposes, even though the contents of /sdcard may actually be in internal storage.

  1. Download the prebuilt release of CyanogenMod you wish to install. (Or if you've built CM yourself, look in the $OUT directory for the .zip.)
    Optional: Download any supplemental 3rd-party applications packages for the device you wish to use.
  2. Place the CyanogenMod rom .zip file on the root of the SD card using adb:
    • Transfer your file(s): adb push /sdcard/
      • If you boot directly to recovery and have an internal sdcard, you may need to run adb shell mount /sdcard or mount data through the recovery menu before transferring.
      • If you see "error: device not found" there is likely a driver issue on the PC.
      • If you see "error: insufficient permissions for device", try "adb kill-server" and then run "adb devices" to see if the device is attached.
      • On some devices, the zip file can be copied to the device using standard USB Mass Storage or MTP support. Boot the device normally and transfer the file to it.
    Optional: Place any supplemental packages (e.g. Google Apps[1] or kernel) .zip file(s) on the root of the SD card.
  3. Boot to recovery mode on the device .
  4. Once the device boots into the ClockworkMod Recovery, use the physical volume buttons to move up and down. On most devices, the power button is used to confirm your selection, although for some devices the power button is used as a "back" button to go up one level, in which case the home button is used to confirm the selection.
    Optional/Recommended: Select backup and restore to create a backup of the current installation on the device. If this option is missing, it's likely because the stock ROM has overwritten your custom recovery on boot.
  5. Select the option to wipe data/factory reset.
  6. Select install zip from sdcard.
  7. Select choose zip from sdcard.
  8. Select the CyanogenMod file you placed on the sdcard. You will then need to then confirm that you do wish to flash this file.
    Optional: Install any additional packages you wish using the same method.
  9. Once the installation has finished, return back to the main menu, and select the reboot system now option. The device should now boot into CyanogenMod.
