Update HTC One X to Android 4.2.2 Jelly Bean via CyanogenMod 10.1 RC5 ROM [How to Install]

HTC One X users can now enjoy rock-stable performance and reliability on their handsets, thanks to the release of latest CyanogenMod 10.1 (CM10.1) Release Candidate version (RC5) from the industrious CyanogenMod team. The CM10.1 custom ROM is based on the original Android Open Source Project (AOSP), which offers stock-like Android experience in a highly-stable release. CyanogenMod RC builds are ideal for everyday use, as they are almost bug-free.

Key Points to Note

• The CyanogenMod 10.1 RC5 ROM and the instructions given in this guide are meant for the HTC One X model only. Verify the device model number by navigating to Settings > About Phone.
• Back up data and settings using a recommended custom recovery tool such as ClockworkMod (CWM) or TWRP, as it creates a complete image of the existing phone setup.
• Verify correct USB drivers for the phone are installed on the computer (download HTC One X USB drivers)
• Ensure USB debugging mode is enabled on the phone, by navigating to Settings > Developer Options (if device is running Android 4.0 or later) or Settings >Applications> Development (if device is running Android 2.3 or earlier). Otherwise if device is running Android 4.2, perform the following steps:
• Go to Settings > About Phone
• Scroll to the bottom of the screen and select Build Number
• Tap the phone's Build Number seven times to unlock or reveal the hidden Developer Options under Settings. Then select the checkbox to enable USB debugging mode under Settings > Developer Options.
• Make sure the phone has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) while installing the ROM.
• Ensure the device isfactory unlocked (not locked to a specific carrier) as well as bootloader unlocked. Also, verify that the phone is rooted with ClockworkMod Recovery (CWM) installed.
• If the device is stuck at booting or is experiencing boot loop issues, perform Wipe Cache Partition and Wipe Dalvik Cache a few more times before rebooting.
• Allow newly installed ROM to stabilise for five minutes before you start working on it.
• If Status 7 error appears on screen then it could be due to an incompatible device being flashed or a related kernel may be missing. For instance, a Jelly Bean kernel needs to be installed before installing any Jelly Bean ROM.
• Instructions provided in this guide are meant for reference purpose only. IBTimes UK reminds its readers that it will not be held liable if device is damaged or bricked during or after the ROM installation. Users are advised to proceed at their own risk.

How to Install Android 4.2.2 Jelly Bean via CyanogenMod 10.1 RC5 ROM on HTC One X

Step 1: Download CyanogenMod 10.1 RC5 ROM for HTC One X and Google Apps

Step 2: Connect your phone to computer via USB cable and then mount its storage.

Step 3: Without extracting, copy the downloaded zip files to the root folder on your phone's SD card.

Step 4: After the file transfer process is complete, Power off the phone and disconnect its USB cable from computer.

Step 5: Now boot the phone into Recovery mode by pressing and holding Volume Down and Power button together. The device will first boot into HBOOT menu where you can select the Recovery option [NOTE: Use volume buttons to navigate and Power button to select an option in recovery].

Step 6: It is advisable to perform a Nandroid backup of your existing ROM so that it can be restored later if the new ROM fails to work or you want to return to the original ROM. To do a backup, click Backup and Restore, then hit Backup again on next screen. Return to main recovery menu once backup is complete.

Step 7: Perform a full data wipe task to eliminate conflicts between newly installed ROM and previous ROM. To do so, first choose wipe data/factory reset and then click Yes on next screen to confirm. Wait for a few minutes until the data wipe process completes. Now return to CWM recovery main menu and select wipe cache partition. Wait until the wiping process completes and choose Wipe Dalvik Cache under advance option. Once the entire data-wiping process completes, you can safely proceed to the next step.

Step 8: Choose Install Zip from SD card and then click Choose Zip from SD card. Now, navigate to the cm-10.1.0-RC5-endeavoru.zip file that you copied earlier in Step 3 and select it by tapping Power button. Confirm the ROM installation on next screen and soon its installation will begin.

Step 9: After the ROM installation completes, repeat the step 8 but choose gapps-jb-20130301-signed.zip instead of ROM zip to install Google apps package.

Step 10: Once both the ROM and Google apps are installed, return to the main recovery menu and hit reboot system now. The phone will now reboot into the newly installed ROM. However, the first boot may take about 5 to 15 minutes to complete. So, do not interrupt the process.

Returning to Previous ROM: To return to your previous ROM: boot the device into recovery, choose Backup and Restore then restore your original ROM by choosing it from the list.

Congratulations! Android 4.2.2 Jelly Bean based CyanogenMod 10.1 RC5 ROM is now installed and running on your HTC One X. Go to Settings > About phone to confirm the firmware installed.
