Update HTC One M7 with CM11 M8 Android 4.4.4 KitKat Firmware

A new built of CM11 is out as M8 snapshot has been officially released by the CyanogenMod team for more than 80 Android based devices. Well, the same Android 4.4.4 KitKat based custom ROM is now compatible with HTC One M7, which means that we will be checking how to install CM 11 Snapshot M8 on your smartphone. All you need to know about the update process can be accessed by reading the following lines, so if you are considering in flashing Android 4.4.4 KitKat CM 11 firmware on your HTC One, don’t hesitate and follow the present step by step.

CM 11 represents a highly appreciated Android 4.4.4 KitKat custom ROM, all the users who have tested the official release of the firmware declared that their devices are now more powerful and that they are able to use a more stable and smoother Android OS. With the new snapshot M8 built of CM11 you can experience even more custom features that cannot be found on the default version of KitKat OS, features that can customize and optimize the performances of your HTC One M7.

So, CM 11 M8 will install both stock and extra features, apps and capabilities on your HTC One. Of course, all these new features will unchain the internal system of your device, offering access to in built programs and processes. Thus, you will be able to remove bloatware, to speed up your HTC One M8, to improve its battery performances and to personalize and customize the Android interface – you will not experience the stock KitKat OS, as CM 11 features its own UI (the new UI will be more stable and also a lot faster).

CM11 M8 Snapshot is stable and runs without bugs, lags, force close errors, or with black screen issues on the HTC One M7. The system has been customized and developed in order to fit the HTC One system, so that’s why this tutorial should be used only for installing Android 4.4.4 KitKat firmware on the mentioned device – if you own a similar or different smartphone use a guide that is compatible with the same.

Of course, CM 11 is a custom ROM and not an official Android OS. The ROM is nothing but a free aftermarket distribution of Android 4.4.4 KitKat software that is only based on stock Android OS – in fact the update is developed and offered by third party devs who have nothing to do with Google or in our case with HTC. That’s why CM 11 can be flashed only manually on your HTC One. Also, that’s why you should consider this tutorial complex and risky as the update operation isn’t an official one.

Due to same considerations, by completing this update guide the warranty of your HTC One M7 will get void – in case you manage to soft brick your handset, you will have to fix your Android device by yourselves. Since you need to update your phone with a custom ROM, root access must be ensured on your HTC One. Without gaining root, CM11 will not work on your phone. Also, the firmware can be flashed only by using a custom recovery image so because of that, before doing anything else install the latest version of CWM or TWRP recovery on your smartphone.

On the other hand, after preparing your phone for the update operation that will shortly follow, also take care of your personal data and of the general pre requisites which will be detailed during the list from below.

  • As mentioned, you need to save your personal data, info and accounts; why? Well because a wipe is required before installing CM 11 M8 on your HTC One.
  • So, place your data in safe hands by completing a full backup via cloud services or by using compatible apps from Google Play – do save your contacts, call logs, text messages, internet settings, market apps and everything else you might need.
  • Since you will run on a custom ROM, the best will be to make a Nandroid backup before adding the Android 4.4.4 KitKat software – in this way you can save and eventually restore the current ROM.
  • The CM11 custom ROM file will have to be downloaded on a computer first – a connection between your computer and your phone will have to be established afterwards.
  • In order to make things right and for avoiding unpleasant situations from happening, on your computer temporarily deactivate the antivirus and antimalware programs (the security tools might interfere with the download process) and on your HTC One enable the USB debugging option from “menu – settings – developer options” (else you might not be able to properly connect your devices).
  • It is quite important to charge your handset if the battery status indicates less than 50% power left: your smartphone might get bricked if it gets turned off in the middle of the update operation.
  • As mentioned already, this tutorial is compatible only with the HTC One M7 since the CM 11 M8 Snapshot Android 4.4.4 KitKat update file provided below is suitable only with the same.
