Install CM 11 Android 4.4 Nightly ROM for Samsung Galaxy S4 LTE I9505

The official Nightlies of CyanogenMod 11 are now available for the Samsung Galaxy S4 LTE model number I9505. Installing the new custom ROM for your device is easy if you follow all the info that is listed in this article.

Remember that this is a post for users who want to tinker with their Android device and test as many custom ROMs as possible until they manage to find their day-to-day OS build. CyanogenMod 11 comes with tons of innovations besides the AOSP Android 4.4 features that will make your smartphone run smoother than ever.

After the Unofficial CM 11 builds, the Nighlties is the first build that is officially released by the CM team. However, note that these aren’t the most stable releases, but you will still get a better experience than you would get with the stock TouchWiz UI. If you like the stock Samsung experience then you shouldn’t flash any new custom ROMs.

Learn more about the new features and improvements added by CyanogenMod 11 Nightlies to your phone via the CM developers web page. Before starting the installation you will need to take a look at the preparation guide below and start learning how to successfully update your Galaxy S4 with the latest CM 11 Nightly build. Here’s what you need to know:

  • this tutorial works only with the Samsung Galaxy S4 model number I9505.
    – do not attempt to update any other Galaxy S4 variant with the files that you find in this post.
  • your phone has to be rooted and running the latest CWM Recovery image.
    – TWRP Recovery might work too, as long as it is updated to the latest available version.
  • ‘factory reset’ is needed in order for the new custom ROM to be applied, so that the new ROM will flash successfully.
    – this ‘factory reset’ process will remove all data stored on your smartphone’s system partition, while the internal / external parts will be left unaffected by it.
    – this step can be found in the tutorial.
    > Galaxy S4 devices that are already sporting an official CM 11 Nightly ROM can be updated with a new build without ‘factory reset’.
    > if you skip Factory Reset and the phone doesn’t boot in normal mode with the new build, then you will be forced to return to this step and repeat the entire tutorial once again.
  • make sure not to skip the NANDROID ROM Backup step, as it will help you setup a restore point for your Galaxy S4.
    – such file can be used in case the new ROM doesn’t boot in normal mode or in case you wish to restore your phone to its current ROM.
  • backup data from installed applications using the Helium tool for Android — Google Play Store link here.
  • SMS text messages and APN Internet Settings can be saved with the following apps: SMS backup & restore | APN Settings Backup & Restore.
  • sync Contacts info with your default Gmail account.
  • enable USB Debugging from Developer Options menu.
  • charge the phone’s battery until it reaches at least 50% power, so that it won’t switch off in the middle of the updating process.
