Update HTC One X to Android 4.4.2 KitKat via CyanogenMod11

Just like any other Android user, HTC One X users are also eagerly waiting to get the Android 4.4 KitKat on their smartphones. HTC had announced that HTC One and HTC One Max will be getting the flavor of KitKat by the end of January 2014 but no official update for rest of the models yet. So it’s highly unlikely that the update will come to HTC One X before the Q2 of 2014.

So until an official update surface, our only option is to flash custom ROMs to see the KitKat magic. The custom ROM developments are in primary stage and there are not many stable options available yet. Thömy, a senior developer at XDA developed a KitKat version ROM for HTC One X based on CyanogenMod 11.0. This is also an early build so you may face some problems here and there, but the KitKat experience really worth it to give a try.


So if you are willing to give a try on CM custom ROM, then follow the below tutorial carefully to do the same. Remember that your warranty will be void once you root and install a custom ROM on your device.


  • Must take a backup of stock ROM and the data.
  • Charge your mobile battery to a sufficient level (70% to 80% advised).
  • Enable the USB debugging from ‘Settings -> Applications -> Development -> USB debugging’.
  • Your device Boot loader must be unlocked and device should be rooted. If you haven’t done it already, follow the steps here.
  • Install latest version of CWM Recovery on your device.
