Update Verizon HTC Droid DNA to Android 4.4.2 with SlimKat Custom ROM

The Android 4.4.2 KitKat firmware will not be released for all the Android based smartphones and tablets out there. As usual, when a new update is being released the same will be suitable only with limited devices, while the other ones will be stuck on older versions of the software. This is how Google is telling us that we should change our phones. But if you are not planning in buying a new handsets and still want to use a test the new Android 4.4 OS, then you need to use a custom ROM firmware.

What I have mentioned above can be applied also for the Verizon HTC Droid DNA. As you might know, Google and HTC announced that the Droid DNA will not receive the official touch of Android 4.4 KitKat OS due to hardware limitations. We all know that the DNA is a decent Android device, so the KK firmware might just work perfectly. Anyway, even though there won’t be any OTA rolled out for the Verizon DNA, you can still install Android 4.4.2 KK OS on your phone. How? Well, as I have mentioned during the introduction, by flashing a custom ROM firmware.

Therefore, if you choose to follow and complete this step by step guide, you will be able to learn how to easily and safely update your Verizon HTC Droid DNA to Android 4.4.2 software by using the new SlimKat custom ROM platform. The SlimKat firmware is based on the latest release of Android (which currently can be spotted only on Nexus handsets) and represents a free aftermarket distribution of Android OS. So, SlimKat is developed by third party devs (we should thanks those of xda-developers for the present tutorial) which means that the update has nothing to do with Google, with HTC or with Verizon.

The best is that SlimKat will be bringing stock and extra (that cannot be found on the default Android 4.4.2 system) features, apps and capabilities that can be used for improving the performances of your Droid DNA. Furthermore, with SlimKat installed on your DNA you will be able to enjoy a stable variant of KitKat OS, though the stock or pure Android UI will be replaced with a custom one. In a few words, with this custom ROM you will be able to power up your device by increasing its speed, updating the web browsing experience, upgrading the battery life, remove the bloatware, access the internal system and so on.

If you want to obtain all that and even more, then you must complete this guide for learning how to update your Verizon HTC Droid DNA to custom Android 4.4.2 KitKat firmware. But, for being able to do so, you first have to prepare your device for the flashing operation that will shortly follow. Because of that I have explained the pre requisites from below.

  • Root your Verizon Droid DNA; gain root access because a custom ROM is not an official update and the same can be applied only on an unchained system.
  • Be careful when rooting your smartphone because root is not official either. By doing the same you will void the warranty of your Android device.
  • The warranty can be restored only if you choose to downgrade your Droid DNA to stock Android JB firmware – then the root access will be revoked and the default version of Android reinstalled.
  • Install a custom recovery image, I recommend you to use CWM or TWRP recovery (the latest version of these apps). If you try to use the stock recovery for flashing a custom ROM you will notice that isn’t possible. So, flash the custom recovery and update your Droid DNA to Android 4.4.2 OS.
  • Do note that a custom recovery app can be installed only on a rooted system, so complete the root first.
  • Backup your Droid DNA data, including personal info, accounts, contacts list, messages, call logs, market apps and basically everything else is saved on the internal storage memory.
  • You can even save the current ROM by completing a Nandroid backup – in this way, if the SlimKat software isn’t good enough for you, you will be able to safely restore the previous ROM without having to follow a complicated and complex tutorial like the present one.
  • Make sure you can use a computer or notebook, your Verizon HTC Droid DNA and its USB cable.
  • On the mentioned computer you should first deactivate the antivirus or any other security program.
  • Then, on your device you need to enable USB debugging option; you can do so by heading to path “menu – settings – developer options”.
  • Up next, you need to check the battery status; if the power is less than 50% then you have to plug in the charger before going any further, else you can skip this step.
  • This step by step guide is compatible only with the Verizon version of the HTC Droid DNA. So, don’t use the next steps for installing the Android 4.4.2 KitKat based SlimKat custom ROM on a different or similar Android device – you can end up in bricking your smartphone.
