The One is HTC’s flagship device launched earlier this year. This 4.7″ powerhouse has a 1.7 GHz quad-core Qualcomm Snapdragon 600 processor, 2 GB RAM, 4 MP ultrapixel rear camera, 2.1 MP front facing camera, 32/64 GB internal memory options and a 2300 mAh non-removable battery. On the software front, it has HTC’s Sense UI, Beats Audio sound enhancement and originally ran on Android 4.1.2, received a 4.3 update couple of months back and will also receive Android 4.4 in the near future.

As the One is a popular flagship device, there are a lot of custom ROMs for it. We had previously seen how to install the AOKP ROM, the Paranoid Android 3.99 ROM and even the official CyanogenMod 10.2 ROM on it. However, all these ROMs were based on Android 4.3 and now after the launch of Android 4.4, the users might want to install custom ROMs based on the Android KitKat OS. We had already seen how to install an unofficial version of the CyanogenMod 11 ROM on the One before, as the official ones weren’t released yet. Now, with the official builds out, let us see the steps involved in installing them on the device.

Pre-requisites and Backing up your HTC One:



  1. Download the latest CM 11 ROM zip file and the Gapps zip file and copy it to the root of the internal storage of your HTC One.
  2. Now boot into recovery. You can follow this method: Turn off your device and then press the volume down and power button together until the HBOOT menu is displayed. Then use the volume button to navigate to “Recovery” and select it using the power button.
  3. Now you have to perform a full data wipe.

    If you are using CWM custom recovery, follow the below steps:
    A. First select “wipe data/factory reset” and then choose “Yes”.
    B. Select “wipe cache partition” and then choose “Yes”.
    C. Finally select “advanced”, then select “wipe dalvik cache” and then choose “Yes”.

    If you are using TWRP custom recovery, just tap on “Wipe” and perform “Swipe to Factory Reset”.

  4. Next select “Install Zip”, then “Select Zip” and choose the CM 11 ROM zip file.
  5. Again select “Install Zip”, then “Select Zip” and choose the Gapps zip file.
  6. After the installation is complete, reboot your device.

You have successfully installed official CyanogenMod 11 (CM 11) ROM on your HTC One.

Note: The ROM is still in nightly stages and may contain few bugs.
