In order to make sure that you successfully flash the new OMEGA build for your device, you should first take a look at the preparation guide below. Make sure to read all guidelines and only when you’re sure that you wish to install OMEGA, move to the tutorial guide. Here’s what you need to know:

  • use the tutorial only with Samsung Galaxy S4 model number I9505. Don’t try to flash the files you find here on any other Android / Samsung smartphone.
  • the device has to be rooted and running a custom Recovery image such as TWRP. This tutorial use the TWRP Recovery image and not the CWM. You can try to flash this custom ROM with CWM, but we can’t guarantee that it will work.
  • use the TWRP Recovery to create a NANDROID backup of your current OS. This will set a restore point for your device and you can use it in case something goes wrong and the phone doesn’t want to boot with the new OS.
  • the tutorial contains a steps that asks you to wipe data to factory reset the device from Recovery, but this is optional. However, if you’re currently running a custom ROM on your phone, then you will have to wipe data.
  • Users running stock rooted XXUAME2 Jelly Bean 4.2.2 can skip the Factory Reset step.
  • the data stored on your phone’s internal SDcard will not be affected by the installation of this new ROM.
  • however, the system partition containing installed apps, SMS, call logs info and APN internet Settings might be deleted, which is why you can choose to use the following apps in order to backup some of those data files: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore. If you want to backup installed apps data, then you can search the Google Play Store for such tools.
  • remember to sync Contacts with your Gmail account. The phone numbers and other Contacts data will be backed up using the tutorial here.
  • enable USB Debugging.
  • make sure that your phone’s battery has enough power before switching off completely. In case the device powers off in the middle of the updating process, then you will be forced to repeat the entire tutorial.
  • do not blame us in case something goes wrong, you lose data or you brick your phone in the process.
  • this is a guide for advanced Android users.
  • make sure that you don’t skip any steps listed below.

Now that you know all of the above, I think that you can continue to the next part of this post and learn how to successfully flash a brand new custom ROM for your 1.9 GHz Snapdragon 600  smartphone. In case you cannot complete the install, then you should ask for extra help in comments. We will try to offer you a viable solution for any problems that you might encounter during the installation.

How to install Omega 3.1 Jelly Bean 4.2.2 Custom ROM for Samsung Galaxy S4 I9505:

  1. Download the Omega 3.1 ROM zip file from HERE. Don’t unzip, save the file on your computer’s desktop screen.
  2. Download Gapps for Android 4.2.2 Custom ROMs from HERE. Do not extract the zip contents.
  3. Connect your SGS4 LTE to PC and move both files to the phone’s internal SDcard.
  4. Disconnect the device from PC when the files are copied.
  5. Power off your smartphone and boot it into TWRP Recovery Mode. It can be done if you press Volume Up, Home and Power buttons. Release the buttons when the TWRP logo appears and then wait for the device to boot into Recovery mode.
  6. Press the ‘Backup’ button and then create a full NANDROID backup of your device. Select the files you wish to preserve and then confirm by swiping the button shown in the lower part of the screen.
  7. OPTIONAL: If you’re running a stock XXUAME2 rooted firmware, skip this step. If you’re running another custom ROM, then you need to press ‘Wipe’ and then Swipe the button that says ‘Swipe to Factory Reset’. Don’t change any other options/ settings.
  8. Now, press the ‘Install’ button and then browse your phone for the Omega zip. Load it into TWPR Recovery and then press ‘Add more zips’.
  9. Find Gapps file also and select it for installation.
  10. Now, ‘Swipe to Confirm Flash’ and wait until the installation process is complete.
  11. When the install is finished, you should return to the main Recovery menu and press ‘Reboot’.
  12. Select ‘System’ and wait for the phone to boot into normal mode using Omega Jelly Bean 4.2.2 ROM.
  13. Enter your Google Account details and take control over your smartphone’s functions.
  14. Test all the new features and functions.
  15. Tell us in comments how is your Galaxy S4 I9505 working with this new custom ROM.

These were all the steps that you had to take in order to update your smartphone. If the first boot process doesn’t complete, then you will have to power off the phone by removing its battery. Re-insert the battery after 5 seconds have passed and then you have to boot into TWRP Recovery mode once again. Select ‘Wipe’ and then apply the ‘Factory Reset’ task. Wait for the phone to complete this process and after that you should repeat the entire tutorial.

In case the new OS isn’t working as you had expect it to, then you should boot to Recovery Mode and restore NANDROID backup file for previous OS. This should take only 5 minutes.
