CyanogenMod 10 (CM10) ROM is easily the most popular Jelly Bean custom ROM currently available in the Android market, owing to its high customization capability and faultless performance. With the new ROM it is now possible to get the Android 4.2 Jelly Bean OS for the international variant of the HTC One X.

The ROM has arrived courtesy XDA Developers member TripNRaVeR and his TripNDroid Mobile Engineering team, and based on Android 4.2, the ROM has a hardware Menu key that is mapped to the Recent Tasks button. The ROM comes with a true Jelly Bean kernel and it supports all HBOOT versions of the HTC One X.

Before going ahead with the flash, it is important to note that the following instructions are only meant to be used with the HTC One X, model number PJ46100, and applying these instructions on another device or model may lead to certain undesired consequences.

Moreover, users undertake the installation at their own risk and MobilenApps will not be held responsible for any damages that could happen to the device after following the instructions. It is better that users read and understand the whole guide first before actually performing the instructions.

Users will need an HTC One X PJ46100 with ClockworkMod Recovery installed (see here on how to install ClockworkMod Recovery on the HTC One X), a Windows PC, Disable antivirus, firewall, and other security software. Also disable HTC Sync and other software that accesses the phone as such software can interfere with the procedure in this guide.

It is also important to enable USB debugging on the handset with handset USB drivers installed on the PC (can be done by installing HTC Sync). The device’s battery has to offer at least 70 percent power and backing up personal data is also recommended.

Here are the steps to install:

• Step 1: First copy the CM10 ZIP file to the phone’s internal SD card. (See below for download links)
• Step 2: Next, on the PC, extract the Fasboot.zip. A folder named Fastboot should be obtained.
• Step 3: Now extract the boot.img file from the cm10_endeavoru-ota-eng.noeri-028.zip file and place it into the Fastboot folder.

• Step 6: Connect the phone to the PC via USB cable.
• Step 7: Users will now need to open a command prompt on the PC and navigate it to the Fastboot folder.
• Step 8: In the command prompt, type fastboot devices to check if the device has effectively connected to the PC. The phone’s serial number should now be displayed on the screen.
• Step 9: Flash the boot.img by typing the following in the command prompt: fastboot flash boot boot.img
• Step 10: Now head back to the phone and select Bootloader to go back to the main Bootloader menu.
• Step 11: Next, in Bootloader Mode, highlight Recovery using the Volume keys and select it by using the Power button to boot into ClockworkMod Recovery.
