Well, if you had decided to go further with this guide, then here is what you need to know and do. First, as you are about to install the Jelly Bean Maximus 4.0 custom ROM (which is not an official firmware released by HTC for your HTC One X), you need to backup the date that is saved on the internal storage memory of your phone. For this, you can use suitable backup and restore tutorial from our website; just go and search for the same through the how to section. You can learn how to backup the text messages, the contacts, the call logs, the current ROM and a lot more.

When you are done with the backup, you should first root the One X. The Jelly Bean update cannot be flashed on a system that has the factory restrictions installed. That’s why you also need to unlock the bootloader of your smartphone. You must be aware as by performing these operations, the warranty will get void. You shouldn’t worry though as the warranty can be restored by downgrading to the stock ROM, or by updating with an official software launched by HTC. Also, even though a custom ROM (One Maximus in our case) will be running on your device, you will be able to apply an official update whenever you will want.

Furthermore, you will have to get and install a custom recovery image for your One X. CWM recovery is the most popular recovery image, so you can anytime apply and use the same. This tool will be used for flashing the update file from the SD card to the internal system and also for wiping the data; but more about this during the steps from below. Now, you should end the pre requisites by taking care of the next mentioned list; you can then safely head to the basic tutorial, so let’s get started:

  • Go to “Settings -> Applications -> Development -> USB debugging” and enable the USB debugging option from your phone.
  • On the device, deactivate the antivirus program and protection as it might interfere with the update process.
  • The phone must have enough battery life remained in the system; if there is at least 60% power left, than you shouldn’t stop for charging the battery.
  • Don’t forget the backup, root, unlocking the bootloader and the custom recovery image operations (see the above mentioned lines).
  • Do not apply this guide for similar handsets with the HTC One X as you can end up in bricking them.
