Update Motorola Atrix HD to Android 4.4 KitKat with PSX Custom ROM Firmware

If you want the best for your Android based handset then you must try the new Android 4.4 KitKat firmware. I know that for now the new Google OS is available only for Nexus devices, but that’s not an excuse for you. Therefore, even before the official release of Android 4.4 you can flash the same on your Motorola Atrix HD by using a custom ROM software. So, during this guide I will try to help you out by teaching you how to install the new PSX (Pure Speed X – based on Android 4.4 KitKat) system on your Atrix HD.

It should be clear for you that PSX, or Pure Speed X firmware, is not an official platform; this software has been developed by third party devs so it has nothing to do with Motorola or with Google. Actually, those of xda-developers are behind this so we have them to thanks them for this step by step guide. So, this Android 4.4 KitKat OS isn’t an official update released for your Atrix HD, which means that this operation isn’t official. That’s why you should be careful when applying the guidelines from below; stick to my indications and don’t perform things by yourselves as you can end up in bricking your handset.

If you are wondering, PSX is a ported version of Android 4.4. Because of that, by flashing the firmware on your Motorola Atrix HD you will not be able to use the pure Android software. The custom ROM is coming with its own looks, user interface, features, apps and capabilities. Actually, on this firmware there are included both stock and extra (that cannot be found in the default variant of KitKat system) features that can be used for improving the performances, for upgrading the speeds, battery life, web browsing experience and so on.

The PSX ROM is also stable and comes without major bugs or issues. According to the devs and to those who have already used this Android 4.4 KitKat OS the PSX system can be installed for a daily use. All the main features and apps are working properly so you have nothing to worry about.

Related to the info mentioned in the beginning of this tutorial, since we are dealing with an unofficial procedure, by completing the same the Motorola Atrix HD warranty will get void. Unfortunately, this aspect can’t be avoided since your smartphone must be rooted and installed with a custom recovery image. The root access must be granted because a custom ROM can be flashed only on an unchained system because the firmware needs to access some in-built programs and tools. But, by gaining root access you will remove the factory and default restrictions which will imply in losing the warranty.

In case you will need the warranty back, you will be able to do so as the root access can be easily revoked. In order to do that, downgrade your Atrix HD to stock Android OS, or update with an official release of the Android system. Then the root will be revoked, the stock Android re-installed and your handset will be restored to its initial state thus the warranty will be regained.

Also, as I have mentioned, on your Motorola Atrix HD, if you want to update to Android 4.4 KitKat firmware, a custom recovery image must be flashed. The custom recovery will be used for applying the PSX system from the SD card so completing these steps are not an option for you. I recommend you to use the latest version of CWM or TWRP recovery because these tools have been used by the devs when the PSX ROM was tested on the Atrix HD.

After that, you should consider in backing up the data which is saved on the internal storage of your smartphone. The backup can be easily applied as on rooted devices you can install free distributed backup and restore tools from Google Play. Do note that a wipe will be required so you should definitely save the contacts list, the call logs, market apps, internet settings, EFS folder, personal data, accounts and info. Also, the best will be to make a Nandroid backup – in this way, if the Android 4.4 custom ROM will not be on your taste, you will be able to easily restore the stock firmware on your Motorola Atrix HD.

For this tutorial a computer or notebook will be required; the same is applying for your phone and for its USB cable. On the computer you should disable the antivirus protection; usually the security programs are interfering (also interrupting) with the update operation and we don’t want that to happen. From the path “menu – settings – developer options” on your device enable USB debugging option (do that if you want to properly connect your phone with the computer). On the other hand, your Atrix HD must be charged especially if the battery status is displaying less than 60% power left – if you device gets turned off during the flashing procedure, you will risk in bricking your Android device.

This step by step guide is compatible only with the Motorola Atrix HD. So, use the steps from below for updating to Android 4.4 KitKat OS via PSX custom ROM firmware only if you own the mentioned handset, or else you can damage or brick your smartphone or tablet.

How to Update Motorola Atrix HD to Android 4.4 KitKat with PSX Custom ROM Firmware

  1. First you have to download the Android 4.4 update from here; place the firmware on your computer, preferable on desktop.
  2. Also do the same for Google Apps package – download the file from here (Google apps are not included on the software system so that’s why you need to install it separately).
  3. Don’t unzip these files, just place them on desktop.
  4. Connect your Atrix HD with your computer by using the phone’s official USB cable.
  5. Remember that on your handset USB debugging must be enabled.
  6. Now, copy paste or drag and drop the downloaded files from desktop to your phone’s SD card.
  7. Then remove the USB cable because the computer is no longer useful for us.
  8. Good, now enter your device in recovery mode; if you don’t know how, use our dedicated tutorial that will explain you how to enter recovery mode on rooted and un-rooted Android devices.
  9. From recovery you then have to wipe the system; so select “wipe data factory reset”.
  10. Return to main menu of recovery and choose “wipe cache partition”.
  11. Continue by selecting “advance” and then pick “wipe dalvick cache”.
  12. Once more go back to recovery.
  13. This time select “install zip from SD card” followed by “choose zip from SD card”.
  14. Take, or pick the Android 4.4 KitKat PSX Custom ROM file from the SD card.

  16. Return to recovery and repeat this process for flashing the Google Apps package.
  17. When the update operation ends, from recovery select “+++go back+++” and “reboot system now”.


The first boot of your phone might take longer to complete than usual. In case that happens, don’t panic as this is a normal thing to happen – there is nothing wrong with your device, just wait while Android 4.4 OS is being booted.

On the other hand, if on the first boot your Atrix HD gets stuck, then you have a problem. In order to resolve the same you will have to go back to recovery mode. Then, from there you once more need to select the following options: “wipe data factory reset” and “wipe cache partition”. Finally, go back to main menu of recovery and select “reboot system now”.

If you don’t like the PSX custom ROM firmware, then you need to go back to previous or stock Android OS. Now, if you have made a Nandroid backup as I have indicated you before, you can make the restoration process easily without using a dedicated tutorial. All you have to do is to boot into recovery mode and from there to select the option dubbed as “backup / restore”; follow the prompts and that’s it.
