HTC One X+ Gets Android 4.2.1 Jelly Bean Update via AOKP ROM [How to Manually Install]

HTC One X+ users are in for a special treat as the flagship phone receives the latest Android 4.2.1 Jelly Bean update via Android Open Kang Project (AOKP) custom ROM. The handset is still awaiting its official firmware for Android 4.2.1, while there is no word from HTC about its estimated time for release. One X+ users who cannot wait for the official release can follow our step-by-step guide to manually install the latest Jelly Bean custom firmware on their phone.

Key Points to Note

AOKP ROM and the instructions given in this guide are applicable to the HTC One X+ model only. Verify the device's model number by navigating to Settings > About Phone.

Back up important data and settings on the phone by using one of the recommended custom recovery tools such as ClockworkMod (CWM) or TWRP, as it creates a complete image of the existing phone setup.

Make sure correct USB drivers are installed for the phone on computer (download HTC One X+ USB drivers).

Verify the device has at least 80 per cent battery charge to prevent unexpected device shutdown (due to battery drain) during firmware installation.

Enable USB Debugging mode on the phone by navigating to Settings > Developer Options (if device is running Android 4.0 or later) or go to Settings >Applications> Development (if running Android 2.3 or earlier). If the phone is running Android 4.2, then do the following steps:

Ensure that the device is factory unlocked (not locked to a specific carrier) and rooted with CWM recovery installed on it. Download and install Root Checker app from Google Play Store to verify if the device is actually rooted or not.

If the device is stuck at booting or experiencingboot loop issues, then perform Wipe Cache Partition and Wipe Dalvik Cache a few more times before rebooting.

Allow the newly installed ROM to stabilise for at least five minutes before working on it.

The instructions provided in this guide are meant for reference purpose only. IBTimes UK reminds its readers that it will not be held liable if the device is damaged or bricked during or after firmware installation. Users are advised to proceed at their own risk.

Wait until the ROM installation completes, then click Go Back and tap Reboot System Now. NOTE: Repeat the Step 6 for installing Google Apps as well.
