It is a sad period for Samsung Galaxy S3 users as the device has reached its expiry date and won’t be getting any further updates by the manufacturer. To make things worse, the S3 ended with so many bugs still plaguing the device.
This isn’t the case for the much older Samsung Galaxy S2. The predecessor to the S3 has long been released and it is still able to enjoy all the latest updates available. This is thanks to CyanogenMod, which have created countless custom ROMs for the device.
Today, the Samsung Galaxy S2 GT-i9100 gets the latest Android 4.4 KitKat. This can be installed on the phone with the CM11 ROM. Also, users who installed it will get access to countless CM apps.
If you are a GT-I9100 user, then you can update your device right away by following the guide below.
Pre-requisite
1. Flash this firmware to the Galaxy S2 GT-I9100 only. Doing it on other models will risk bricking it.
2. Root the handset and then install a custom recovery like ClockworkMod.
3. Install the USB drivers for your Galaxy S2 on your PC.
4. Make a manual backup of all your personal info, settings and data files.
5. Ensure that your battery level is at least 50% to stop any power interruptions during the flash.
6. Enable the USB debugging mode on your phone. Head to Settings > Applications > Development > USB debugging mode or Settings > Developer options > USB debugging.
7. Download CyanogenMod 11 for Galaxy S2 i-9100 and the Google Apps package to your computer.
Flashing Instructions
1. Connect your Galaxy S2 GT-I9100 to your PC via USB.
2. Copy the CyanogenMod 11 and the Google Apps packages to the SD card of the Galaxy S2. Do not extract the zip files.
3. Unplug the phone from the PC before turning it off.
4. Reboot into recovery mode by pressing and holding the volume up, home and power keys at the same time until the Samsung logo appears.
5. Inside recovery mode, make an Android backup of your current ROM. Select “backup and restores > backup.” You can then restore the saved ROM inside the SD card anytime you need to.
6. Do a full wipe on your phone. Select “wipe data/factory reset” and “wipe cache partition.” Then choose “advanced > wipe Dalvik cache.”
7. Return to the main menu and install the CyanogenMod 11 by selecting “install zip from SD card > choose zip from SD > search the ROM you have copied earlier > confirm installation.” Do the same thing with the Google Apps.
8. Once the installation has completed, go back and select “reboot system now.”
9. It might take five minutes or so before your Galaxy S2 reaches its home screen after rebooting.
