How to flash Pound ROM Unofficial CM11 KitKat for Galaxy S2 I9100:

  1. Download the custom ROM from here.
  2. Download Gapps for Android 4.4 ROMs from here.
  3. Connect your smartphone with your PC and then move both zip files to your device’s internal storage.
    – disconnect your smartphone from computer when the files are transferred.
    – do not unzip the contents of the archives.
  4. Power off your smartphone now.
  5. Boot the device in CWM Recovery mode.
    – it can be done if you press and hold Volume Up, Home and Power, all at the same time.
    – release the buttons when the home screen appears.
  6. First you need to apply the NANDROID ROM Backup step.
    – select ‘backup and restore’, then save the file on your device.
    > continue to the next step when done.
    > do not skip this step as it will create a restore point for your device, one that you can use in case the smartphone doesn’t boot with the new ROM.
  7. Now you have to Factory Reset the device:
    – select ‘wipe data/ factory reset’, confirm.
    > note that you shouldn’t skip this step.
    > if you skip Factory Reset, then the phone will not boot with the new ROM and you will be forced to repeat the entire tutorial more than once before completing the installation.
  8. Next, flash the new custom ROM:
    – select ‘install zip from sdcard’, then ‘choose zip from sdcard’.
    – find the Pound Rom KitKat zip file and confirm its installation.
    > do not press any buttons until the installation is complete.
  9. After the ROM is installed you will need to repeat step 8 and flash the Gapps zip too.
  10. When you complete the installations you need to return to the main custom Recovery screen.
  11. Reboot your smartphone now.
    – note that the first boot process will take a while before loading all the files, which is why you shouldn’t press any buttons until that happens.
  12. Enter your Google account details when the home screen of your device appears.

These were all the steps that you had to take in order to complete the installation of Pound ROM Android 4.4 for your Galaxy S2 I9100. I hope that you did manage to complete the installation and that now you’re testing and tinkering with all of its features.

Remember that this is a custom Android 4.4 ROM which is why you shouldn’t expect your device to have a better battery life, as the KitKat OS usually needs much more power and this will affect the performance of your device. In case your phone doesn’t work as you would have expected it to, then you can always use the NANDROD ROM Backup file created in step 6 and restore it to its previous ROM build.

NOTE: if the tutorial doesn’t complete or the first boot process takes more than ten minutes to complete, then you will be forced to remove the phone’s battery. Re-insert the battery and then repeat the entire tutorial once again and make sure that you won’t skip any steps that I’ve listed above. Also, if you need any extra help, then you should ask for it in comments by leaving a detailed comment. We will come up with a viable solution and help you complete the update of your device to KitKat.

Now that you know all this, enjoy your brand new custom ROM.
