And also by installing this ROM you will void your device warranty. For that we would not be held responsible or liable. So, do everything at your own risk.


Before start to move on to the procedure I strictly advise you to follow the given below pre requisites.

1.First you need to make sure whether your HTC One X smartphone is rooted. Incase, if you are not sure, then download the Root Checker app from Google Play Store and confirm the same.

2.In case, your smartphone is not rooted then follow this procedure to root HTC One X smartphone.

3.After that take backup of all your internal data’s including SMS, MMS, Contacts, Videos, Images, Songs, Files, APN settings, MMS Settings, Bookmarks and other things which you feel it is important for future use.

4.Next disable all the security measures like antivirus and firewall on both your computer and HTC One X smartphone.

Procedure to install Android Jelly Bean 4.2.2 custom ROM in HTC One X smartphone:

1.First remove the memory card from your HTC One X smartphone and insert it into the computer using a card reader. For this procedure you are not supposed to use a USB cable, since the Cyanogen Mod is not working properly in USBs.


In case if you do not have memory card reader then you can try this procedure by connecting your android smartphone to the computer with the help of USB. But I  recommend to use the card reader rather than USB cable.

2.So, once you inserted the card reader into the computer download the Android 4.2.2 CM 10.1.0 RC2 HTC one X endeavoru; zip file from here to your computer.

3.Next again download the android 4.2.2 from here to your computer.

4.Here, try to understand why am asking you to install Gapps in your Android device.Because, official Gapps are available only in the official ROMs and not in any custom ROMs (due to the licensing issues). Therefore, after flashing the custom ROM, you must install the Google Apps separately to your android smartphone. Importantly it should specifically available for your android version.

5.So, once you downloaded both the above mentioned files, copy them into your SD card. Give the folder name as “ROOT”. Don’t try to open this file; simply copy them and keep it in the root folder.

6.Now, remove the memory card reader from the computer switch of your HTC One X and simply insert them again in your smartphone.

7.After that allow your device to enter into the recovery mode by pressing the Volume down button and Home button simultaneously. While pressing these two buttons press the power button also at that time.

8.Once you done that, your device entered into the recovery mode. There you need to select the Wipe Data/Factory reset option. By selecting this option all your data’s will get wiped off.

9.Next again select the Wipe Cache Partition option. This option will wipe all the caches from your device memory.

10.After that move on to the Wipe Dalvik Cache option. This will wipe all the Dalvik caches from the device.

11.So, once you wiped out all the data’s and caches, you need to select the “Install zip from SD card” option and “Choose zip from SD card” option. This option let’s you to browse the file from the SD card.

12.Now, navigate to the root folder which you have already copied into the SD card. There select the zip file and flash it on your device. Again select the Gapps and flash it.

13.Once the flashing is finished, get into the main menu by pressing the back button. After that reboot the HTC One X smartphone.


Now, you successfully installed the Cyanogen Mod 10.1.0 RC2 ROM into the HTC One X smartphone. Thus, the HTC One X smartphone users can enjoy almost 90% of the Android Jellybean 4.2.2 ROM features.
