Update Sprint HTC One with Unofficial CM11 Android 4.4 KitKat Custom ROM

CM11 is here and available for your Sprint HTC One. Even though the CyanogenMod team announced that CM11 based on Android 4.4 KitKat software is on development page only a few days back, now an unofficial port of the firmware has been already made available for the Sprint version of the HTC One. So, if you want to test the new CM platform along with Google’s latest Android OS on your own smartphone, you should complete this detailed step by step guide. Don’t worry, because the steps are not complicated as the update process is quite similar with the usual operation that is used when dealing with custom ROMs systems.

CM11 will be the latest release of CyanogenMod ROM, the devs working hardly on proving a stable firmware for all the Android based devices out there. But until a final and official update will be provided by the CyanogenMod team, the unofficial ports of the same should do the trick. The same can be applied in our case too, as by using this tutorial you will be able to learn how to flash an unofficial variant of CM11 Android 4.4 KitKat ROM on your Sprint HTC One.

So, first of all, this is not an official Android 4.4 update release by HTC for your Sprint One. Furthermore this is not the official CM11 system, as this update represents a custom port of the same. Therefore, do note that on the present CM11 Android 4.4 platform there might be some minor bugs and issues included. Don’t worry though as the CyanogenMod team is working in releasing a stable firmware. But until then, if you just can’t wait, do complete this step by step guide.

This is not the only Android 4.4 KitKat based custom ROM that has been made available for the HTC One as during our previous tutorials we have showed you how to flash the AOSP software on your handset (click the link from above if you want to use that tutorial instead of the present one).

Now, if CM11 is your choice then you should know that even though you might experience some bugs on the build there are also important features, apps and capabilities included on the new CyanogenMod experience. Actually the main features are being included along with the new looks and personalization options. Basically, with CM11 on your HTC One you will be able to test the Android 4.4 KitKat software on full power as the firmware will bump the speeds, upgrade the battery life and improve the Android experience on your Sprint HTC One.

But since CM11 is only a free aftermarket distribution of Android 4.4 KitKat platform (the update is not official and is not coming from HTC or Google) for being able to flash the firmware on your Sprint HTC One you will first have to:

  • Root your handset because a custom ROM can be applied only on rooted systems. An unofficial update is using in-built programs and making changes to the same. Well, for being able to access the internal system, root access must be gained previously; so that’s why you need to root your HTC One.
  • Install a custom recovery image, like CWM, TWRP recovery or any other custom recovery tool that is available and compatible with your Sprint HCT One. You need to do this because CM11 can be flashed only via a custom recovery image as the stock recovery can’t be useful when trying to apply unofficial updates.
  • Flash the custom recovery only after gaining root access; be careful when completing these procedures because the warranty will get void. All the operations are unofficial ones so you can figure it why by yourselves.
  • If something goes wrong, or if you will want to restore the warranty you will basically have to reset the flash counter of your handset; for doing that you need to downgrade to stock Android Jelly Bean OS, or you need to wait for the Android 4.4 KitKat OTA to be released – do note that the official Android 4.4 OS can be installed only manually on your HTC One (because your device is rooted).
  • Backup the data of your phone – only the data that is saved on the internal storage memory. Why to do that? Because, on the flashing operation of CM11 a wipe will be required. What does this means? It means that everything that is saved on the internal storage (like text messages, call logs, contacts list, market apps, personal data, info and acounts and so on) will be either erased or corrupted. So use backup and restore apps from Google Play and save your data before going any further.
  • Since you are on a rooted HTC One that is installed with a custom recovery image, use the same for saving the current ROM. If the CM11 Android 4.4 firmware will be too buggy then you will be able to restore to stock Android OS.
  • A computer must be near as you will have to use one for downloading the required files.
  • In order to complete the update process you will have to connect your phone with the computer, so your Sprint HTC One and its USB cable must be near you.
  • Since a connection must be established, on your handset you need to go to path “menu -> settings -> developer options” for checking the USB Debugging option.
  • This is a manual operation and when applying manual procedures, your device must have more than 50% power left; if not I strongly recommend you to plug in the charger before going any further.
  • Apply this step by step guide for installing CM11 Android 4.4 KitKat custom ROM on the Sprint version of the HTC One. The steps from below are being compatible only with the mentioned smartphone.
