  1. This guide can now commence. Here is the first guideline: download the Jelly Bean 4.3 CM10.2 custom ROM (file name: cm-10.2-20130807-UNOFFICIAL-endeavoru.zip) and Google Apps archive on the PC, via this link. Unzip them next and plug the phone to the laptop.

  3. Switch the HTC One X off. Enter this smartphone into Bootloader Mode by powering it on while simultaneously pressing + holding Volume Down and Power. Then go to the android-sdk-windowsplatform-tools folder.
  4. Launch Command Line and enter this command:
    fastboot flash boot boot.img
    After you press “Enter”, you need to enter a second command:
    fastboot reboot
    Tap “Enter” again. Some guidelines will pop up on the display, so opt for “Bootloader”.
  5. Go to “Recovery” and opt for a full data wipe of the phone. Which is done by choosing some options as shown underneath:
