The Taiwanese tech giant HTC has begun rolling out Google's latest version of Android to its One X (international version only). The company has confirmed to Android Central that the update for all phones in Asia and Europe is "rolling out now".
Instead of releasing the update to all phones in a particular region, the company is said to be pushing out the Jelly Bean update to selected One X units based on their CID (Customer ID) in each region. The One X with CID of 'htc_612' which are sold to carriers in Taiwan have recently started to receive a Jelly Bean Over-The-Air (OTA) update. The devices with a CID of 'htc_044' are expected to receive Jelly Bean OTA updates today.
The One X was launched with Android 4.0 (Ice Cream Sandwich) and recently the official Android 4.0.4 with Sense 4.1 was released for the device.
In order to verify whether the Jelly Bean update is available for your One X, users should navigate to Settings>> About Phone>> HTC Software Updates>> Check. We expect the update to reach all One X users soon.
Long before the release of the official update to One X, the Jelly Bean ROM (Android 4.1.1) with Sense 4+ was leaked for a number of One X models running on Nvidia's Tegra 3 chip featuring a quad-core processor.
The leak was shared by XDA developer baadnewz. The leaked ROM is not compatible with all the phones but works with certain CID numbers of One X. Due to an issue with updating HBoot with S-On, the ROM was then released for developers only.
Recently, senior XDA developer stuart0001 has released a script that allows users to install the leaked Jelly Bean ROM without any difficulty. Moreover, One X users will be able to return to their stock ROM or install RUU's easily.
