The HTC One X is one of the most well-respected and widely used Android smartphones on the market because of its incredibly sleek design and excellent hardware capacity. Despite the tremendous success of the HTC One X, many users are still waiting to upgrade their phones to Android 4.2.1 Jelly Bean.
Thanks to the seemingly never-ending pool of developers, HTC One X users no longer need to wait for an over-the-air update. The HTC One X can been updated to Android 4.2.1 Jelly Bean thanks to a number of custom ROMs that have been released by the Android developer community. The ROMs that have been created for the HTC One X are entirely based around Android 4.2.1 Jelly Bean, and they can often be updated more frequently than the carrier version of the operating system.
With Android 4.2.1 Jelly Bean, HTC One X users will get one of the fastest and smoothest versions of Android yet. Thanks to "Project Butter," an initiative created by Google, switching between screen and opening applications has never been smoother. The system has also been tweaked to provide faster orientation changes, and it also features the new Google Now service, which basically aggregates all the most pertinent information -- such as flight information, sports scores, nearby events, weather and more -- into one location.
Please note: this method of upgrading the HTC One X to Android 4.2.1 Jelly Bean requires flashing your device. It should also be noted that these instructions are only application to the international variant of the HTC One X. It will not work on any other device.
