How to install KitKat on Galaxy S2 with CM 11

Kris Carlon

I shared the good news this morning that CyanogenMod have added the Galaxy S2 to their list of supported devices for the CM 11 ROM based on Android 4.4 KitKat. I've been running CM 11 for a couple of months now and have been very impressed. Now, you can get the same KitKat experience on the aging but still wonderful international model Galaxy S2 I9100. Here's how to do it.

Warning

The installation of custom ROMs is risky, so if you do not follow the procedure properly, you can end up with an unusable phone. Back up all your data first, charge your battery and proceed with caution. Neither AndroidPIT nor myself will be held responsible for any damage done to your phone as a result of this process.

Prerequisites

I'll assume that your Galaxy S2 (I9100) is rooted and you have already made a Nandroid backup of your system. If you're not rooted and are unsure how to root your Galaxy S2, check this S2 root tutorial. You should also backup your app data too as this process will wipe your device.

Downloads

Download the latest CM 11 Nightly for the Galaxy S2 I9100. As always, there's nothing preventing you from flashing a newer version, once it is available.

Also download the Google applications package for KitKat: gapps-kk

Install Android 4.4 on the Galaxy S2 KitKat with CM 11

Since your S2 is rooted, we will use the good old custom recovery method. As a reminder, here is the procedure:

1. Download both zip files given above on your Galaxy S2.

2. Place both files in the root directory of your S2.

3. Turn off the Galaxy S2 and restart in Recovery Mode (Home + Power + Volume Up until the logo appears or the third vibration and release).

4. Perform a factory reset by selecting and confirming the option "Wipe Data/Factory Reset" then "Wipe Cache". Some users prefer to ''Format System'' / ''Wipe Dalvik Cache'' at this point too.

5. Then select "install zip from sd card" and locate the CM 11 zip you downloaded before.

6. Click "Yes" to confirm.

7. Next, flash the gapps zip file.

8. Return to the main Recovery Menu and select "Reboot System Now".

The first reboot on CM 11 may take a few minutes. Let us know how you like it!

    I have already installed the Team Win recovery stuffs on me handset (sgh-t989), and have done a couple of backups already; do these instructions apply to my setup as shown (assuming I have the correct version of cm11), without doing a Nandroid backup?

      Hey @Brock, it depends on how secure you want to be? A Nandroid backup is a full system backup - ie everything. So if you're fiddling and have issues you can get your system back exactly as it was. TWRP and CWM etc only backup apps and data etc, - basically putting your additions back on top of a new base. If everything goes wrong without a Nandroid you'd just have to flash stock firmware or a custom ROM and then add your TWRP/CWM backup on top.

    I don't know how to resolve that particular error; I had the same problem myself and just started from scratch with a fresh stock ROM install, per http://m.youtube.com/watch?v=LNK9zylItTg of course using the appropriate ROM for my device, found at http://www.sammobile.com/firmwares/ then I rooted the phone using the instructions at xda developers, going with the TWRP recovery root..then, once rooted, I downloaded the clockworkmod ROM manager from Play Store, and with that updated from TWRP to clockworkmod recovery, which seems to be necessary to install CM11. Finally, I downloaded the latest nightly Cm11 from http://download.cyanogenmod.org/ directly to my device's sd card, and, after making a nandroid backup with clockworkmod recovery, used said clockworkmod recovery to install the CM11 nightly. This was accomplished after loads of trial and error, thank you and I hope I passed the audition.

        Hi @Rahul, the last stock firmware available for the I9000 was Android 2.3.6, so SamMobile won't have anything beyond that. The only way to get newer firmware is via a custom ROM. As far as I'm aware Error 7 has something to do with your recovery, but I'm not sure what the issue is.

    Hello, I have downloaded and installed the latest Cm11 and for some reason I am not longer able to use my internal sdcard. I can see and use the external sd but not the internal one. I just have the phone with 2Gb for apps and nothing else, unless I put the external sd.
    I saw the partition on via parted is a fat32, but can mount nor format it on CWM recovery nor on my PC. At the end of the day I lost 12Gb of memory on my phone. Is there any way to remove and reformat the UMS partition (12Gb) with parted without having to put the stock ROM back? or....
    BTW I would like to have 8Gb for apps and 8 Gb on my internal sd card, but I really do not know how to do it with Odin and without bricking my phone. Any guidance on this? I want to keep using CM11 of course but could not find the md5 files to be used with Odin for CM11.
    Any help will be much appreciated.
    Thanks a lot.

    Hi Team, I recently upgrade my 2 years old Samsung GS2 with cyanogenmod 11, which work perfectly and the phone touch and feel is superior, thanks for the super duper effort implied by the developers. One issue which is persisting is WIFI-Direct is not working. WIFI-Direct is either not recognizes other devices or recognized by other devices and I am not even to change the name of the WIFI-Direct also.

    Is there any other solution to make this work without any hassle.

    Thanks,
    Karthik
