  • The device that you’re about to update should be factory unlocked, rooted and running a custom Recovery image such as CWM or TWRP.
  • For this new ROM to complete installation you will be forced to apply a Factory Reset.
    – factory reset removes data from system partition, while the internal / external storage cards won’t be affected by this tutorial.

Now that you know all of the above, continue to the next part of this post and learn how to successfully update your device with one of the latest Android 4.4 custom builds.

How to flash Evervol KitKat custom ROM for AT&T Galaxy S2:

  1. Download Evervol Android 4.4 custom ROM zip from here.
  2. Download Gapps for Android 4.4 builds from here.
  3. Connect your phone with your PC and then move both zip files to your smartphone’s internal storage.
    – do not unzip the files.
    – disconnect the phone from computer when all files are copied successfully.
  4. Now, power off the device.
  5. Boot it into custom Recovery Mode.
    – both CWM and TWRP are working with this guide.
  6. First thing that you need to do is to create a full NANDROID Backup for the ROM that is now running on your device.
    > this will set a restore point for your device and it can be used in case the new custom KitKat ROM doesn’t boot correctly.
    – CWM: select ‘backup and restore’ option, then save the file on your device’s internal storage.
    – TWRP: press Backup, rename the file and swipe to back up the system.
  7. Next, apply the factory reset for your AT&T Galaxy S2:
    – CWM: select the option that says ‘wipe data/ factory reset’, then confirm the process.
    – TWRP: press Wipe, then confirm the process.
  8. Now you can install the new custom ROM:
    – CWM: select ‘install zip from sdcard’, then ‘choose zip from sdcard’ option. Find the Evervol Android 4.4 for SkyRocket zip and confirm its installation.
    – TWRP: press Install, then find the custom ROM zip. Swipe to confirm installation.
  9. After the custom ROM is installed, repeat step 8 and install the Gapps zip too.,
  10. When both files are flashed with success, you should return to the main custom Recovery screen.
  11. Reboot your device now in normal mode.
    – note: the first boot process of a custom ROM takes at least 5 minutes to complete, which is why you shouldn’t press any buttons until you see the home screen.
  12. Enter your Google info when the boot is complete, then take control over your device, re-install all your favorite apps and start testing the brand new custom ROM.

These were all the steps that you had to take in order to successfully update your smartphone with a new Android 4.4 custom ROM.

In case the first boot process takes more than ten minutes to complete or in case the device enters into a boot loop, then you will need to power it off completely. After that you should repeat the entire tutorial once again, as these are to be expected when attempting to flash new custom ROMs on Samsung devices.

I hope that you did manage to complete the tutorial and that you’re right now customizing all the parts of your device. If you find any major bugs with the Evervol KitKat 4.4 ROM, then you can report them in comments or in the custom ROM’s XDA thread.

Also, if you don’t like how this new custom ROM works with your AT&T Galaxy S2, then you can restore the device to its previous OS using the NANDROID Backup files created in step 6.
