HTC One X

By now, i am absolutely sure that most of you have heard about the new One line from HTC and its current flagship, the HTC One X. In quite a short amount of time, the first Android smartphone based on the quad core platform NVIDIA Tegra 3 has made a relatively large impact on the current Android market. It seems like HTC is again on its track of gaining market share, although it now has quite a gap to fill if its wants to reach Samsung. As far as the Taiwanese manufacturer is concerned, the One X is the handset that best represents the leap from the last year to 2012, and it looks like most of the company’s loyal fans agree.

As you have read from the title, this article is going to show you all that you need to know in order to successfully update your brand new One X with one of the most popular custom ROM’s out there, Cyanogen Mod 9. For those of you which are still stuck in Android 2.3 Gingerbread era, Cyanogen Mod 9 will bring a much needed ICS update, and thanks to the massive popularity of its Cyanogen Mod 7 predecessor I am sure that many of you will likely hop on the modding wagon and install this great ROM.

As always, there is our disclaimer notice that we must show you. Going past this point in our guide means that you fully understand the risks and you agree with it: This software is not our creation so we must warn you that you cannot hold us responsible for any damage that might occur to your device by following the procedures in this guide. However, we will try to help you sort out any glitches or problems that might arise by following the steps in this guide to the extent our knowledge limits us.

Installing any custom ROM on your HTC One X will void your warranty, so you should be at peace with this tough before going any further. There are also a couple of requirements that your One X must meet before it is ready to start the updating process, and you will find them listed in the lines below:

  • You need to make sure that your HTC One X is rooted and has the ClockWork Mod Recovery installed. If you don’t know how to do any of the above please check out our guide here. The updating process will not work with a non rooted device so please make sure you meet this requirement.
  • Your One X must be charged to at least 60% in order to prevent it from accidentally powering off during the procedure. If your One X does power off during the updating procedure, there is a high risk that it will turn into a very expensive brick.

Before we move on to the interesting part, we still have to cover another very important issue. Updating your One X with any custom ROM means that your personal data will be deleted. In order to avoid losing all your data we strongly advise you to use the applications and procedures below in order to safely save and restore your data once the update process is complete. Just in case you are wondering, we are not using the official HTC Sync software because it does not offer support for any of the custom ROM’s out there, including the Cyanogen Mod 9.

  • Text messages – We will back them up with the following application : SMS Backup & Restore
  • Phone Contacts –  You can simply synchronize them to your Gmail account or export them to the micro SD card as a .vcf file
  • Call Log – We will use the following application to backup your call log : Call Log Backup and Restore
  • Pictures, Music, Videos, and other files – Simply copy them to your microSD card.
  • Internet & MMS Settings – Write down all the settings from this path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names”

With all the aspects regarding the safety of your device and of your data covered, we can now safely move on to the actual updating process. Some of you may still think that it is a risky process, and while it is not risk free, it is highly unlikely for anything to go wrong during this common procedure. With this in mind you can now safely move on to the last part of our guide. Also, please make sure that you follow the steps below in order and that you don’t skip any of them:

  • We will start by downloading this Cyanogen Mod 9 Update package from the internet to your computer.
  • After doing so we are going to use the original USB cable to connect your HTC One X to your computer and we are going to transfer the Zip archive we downloaded earlier to the root of your HTC One X’s internal memory card. Do not place the Zip file into any sub folders as you will have a harder time finding it later on.
  • In step three you will have to disconnect your One X from the computer and shut it down in order to enter the Clockwork Mod Recovery. In order to do so you will have to press and hold the Volume Down Button and the Power Button until you arrive in the HBOOT menu. From here you will have to navigate to the option labeled Recovery and press the power button to select it.
  • Once you arrive in the Clockwork Mod recovery, the first step you need to take is to make a complete nandroid backup of your entire device. You can do so by selecting the Backup and Restore option and on the next screen selecting again Backup. This backup will ensure that you have a working operating system even if something goes wrong. After waiting for the process to finish you will have to return to the main menu of the Clockwork Mod Recovery in order to continue.
  • Now you will have to clear some critical areas of your HTC One X’s internal memory in order to make some room for the new Cyanogen Mod 9 update. All you have to do is to select the Wipe data/factory reset & Wipe Cache partition options from the recovery and wait for them to finish. Once they are done make sure you return to the main screen of the Clockwork Mod Recovery.
  • And finally we have arrived at the most important step. In this one you will actually apply the update, so please select this option: Install zip from sd card followed by this one: Choose zip from sd card, and then simply choose the Cyanogen Mod 9 Update Zip file that you have earlier placed on the internal memory card.
  • In the last step of this guide you will only have to wait for the updating process to finish after which you can safely return to the main screen of the Recovery and select the Reboot now option in order to restart your One X.

A word of caution: the first boot after applying the Cyanogen Mod 9 Update will take a bit longer than a normal one, so do not be surprised if your device only boots up properly after 10 minutes. If, however, you are still stuck at the booting screen for more than 30 min it means that the update has not been successful and you will have to go back into the Clockwork Mod Recovery and retry the steps above. It will also help if you restore that nandroid backup you made earlier just to have a working smartphone again.

If all went well you should now be able to enjoy the blistering speed of the new Cyanogen Mod 9 Custom ROM, and this should also be a good opportunity to see that the HTC Sense interface has been replaced by the stock Android 4.0 ICS vanilla user interface.
