Install Android 4.1 Jelly Bean on the HTC One X

1

If you have to have the latest and greatest Android OS and own an HTC One X you can install Android 4.1 Jelly Bean on your HTC One X. There are some great features that have been added with Android 4.1 on the One X like the improved notification bar, offline voice recognition, updated Google search and performance improvements due to Google’s new “Project Butter”. Its all around a smoother Android experience.

The Android 4.1 Jelly Bean port comes from the new Android SDK (software development kit) and was ported by XDA member tgascoigne for the HTC One X. Keep in mind that the Android SDK version of Jelly Bean is very unstable and should not be installed on your every day phone. There are a few features that are not working in the port to the One X which are as follows: Wifi, audio, and camera.

NOTE: Backup all of your apps as the process will completely wipe your phones data out.


First of all, you have to unlock the HTC One X Bootloader:
