    – this is the guide that should be used for all the US LTE models of Galaxy S4.
    – check your phone’s model number under Settings> About Device.
  • for the tutorial to work your Galaxy S4 LTE has to be rooted.
    – also, you will need to have a custom Recovery like CWM or TWRP installed on it.

    – Factory Reset has to be applied so that you will remove all traces left behind by the already installed ROM.
    – Factory Reset doesn’t remove any data from internal nor external storage, it only wipes the system partition.
  • use Helium for Android app in order to save data from installed applications or SMS text messages.
    sync Contacts info with your default Gmail account.
  • check the battery charge level of your device and make sure that it is over 50%, this will prevent the phone from switching off during installation process.
  • use the guide only if you’re an advanced user and you’re planning on tinkering with your Galaxy S4 ROM.
  • read the whole guide, don’t skip any steps and you should be fine.

How to install CM 11 M8 Snapshot ROM for Samsung Galaxy S4 LTE:

This is the first stable build based on Android 4.4.4 KitKat that has been released by the CM team. It is way better and much more reliable than the Nightly builds, so you should install this if you want to use CM 11 on a daily basis.

  1. Download the CM 11 M8 Snapshot zip file from here.
  2. Download Gapps for Android 4.4.x custom ROMs from here.
  3. Move both zip files to your smartphone’s internal storage after the download is complete.
    – if you’ve used the Galaxy S4 to download the files, then you can skip this step.
    – don’t unzip the files contents.
  4. Switch off the smartphone right now.
  5. Boot the Galaxy S4 LTE in Custom Recovery Mode.
  6. First you need to create the full NANDROID ROM Backup:
    – CWM: select ‘backup and restore’ option. Confirm.
    – TWRP: press Backup, swipe to confirm the process.
  7. Apply the Galaxy S4 LTE Factory Reset:
    – CWM: select ‘wipe data/ factory reset’. Confirm that you wish to wipe all user data.
    – TWRP: press Wipe, swipe to confirm process.
  8. Now you can begin the installation process:
    – CWM: select ‘install zip from sdcard’, then ‘choose zip from sdcard’.
    – TWRP: Press Install.
  9. Find the CM 11 M8 Snapshot zip file and confirm the installation.
    – your Galaxy S4 LTE will take care of the rest and install the CM 11 M8 ROM automatically.
    – do not press any buttons until all files are installed with success.
  10. After the ROM is flashed you need to select the step 8 options and install Gapps zip.
  11. When the CyanogenMod 11 M8 Android 4.4.4 ROM and the Gapps zip are flashed you need to return to the main Recovery screen.
  12. Reboot your phone in normal mode now.
    – note that the first boot process of this new ROM will take a while to load all the new files, so you should wait until you see the CM 11 home screen.
  13. Use your Google Account info in order to take control over your device once again.

These are all the steps that you need to follow in order to complete the installation of CM11 M8 Android 4.4.4 Stable ROM for your Samsung Galaxy S4 LTE.

If the process fails at the first attempt, then you should try to repeat the whole guide more than once. Re-read the guidelines and see if you forgot to check something before starting the update.

If the installation completes with success, but your device doesn’t boot the CM 11 M8 ROM after 20 minutes or it enters into a boot loop, then you will need to try and repeat the guide, make sure to apply step 7 Factory Reset task and then you should go to custom Recovery advanced options and use the ‘format system’ option, too.
