How to Download and Install Android Lollipop on Your Samsung Galaxy S2
If you have a Samsung Galaxy S2 and you want to enjoy the latest features of Android 5.0 Lollipop, you might be disappointed to know that Samsung has not released an official update for this device. However, thanks to the efforts of the CyanogenMod team, you can still get a taste of Lollipop on your Galaxy S2 by installing an unofficial custom ROM based on Android 5.1.1.
In this article, we will show you how to download and install the CyanogenMod 12.1 ROM on your Galaxy S2, which will bring you a smooth and stable Lollipop experience. Before you proceed, please note that this is not an official update from Samsung and it may contain some bugs or issues. Also, you will need to root your device and install a custom recovery like TWRP or CWM before you can flash this ROM. Make sure you backup your data and follow the instructions carefully.
Step 1: Download the ROM and Gapps files
The first thing you need to do is to download the CyanogenMod 12.1 ROM for Galaxy S2 from this link. This ROM is based on Android 5.1.1 Lollipop and it includes all the features of CyanogenMod such as theme engine, privacy guard, notification manager, etc.
You also need to download the Google Apps (Gapps) package for Android 5.1 from this link. This package contains the Google services and apps such as Play Store, Gmail, Maps, etc. that are not included in the ROM.
Once you have downloaded both files, transfer them to your device's internal or external storage.
Step 2: Boot into recovery mode and wipe data
Now you need to boot your device into recovery mode. To do this, turn off your device and then press and hold Volume Up + Home + Power buttons together until you see the recovery screen.
In recovery mode, you need to wipe all the data on your device to avoid any conflicts with the new ROM. To do this, select \"wipe data/factory reset\" and confirm. Then select \"wipe cache partition\" and confirm. Finally, select \"advanced\" and then \"wipe dalvik cache\" and confirm.
Step 3: Install the ROM and Gapps files
Now you are ready to install the ROM and Gapps files on your device. To do this, select \"install zip\" and then \"choose zip from sdcard\" or \"choose zip from external sdcard\" depending on where you stored the files. Then browse and select the ROM file and confirm to flash it. Wait for a few minutes until the installation is complete.
Next, repeat the same steps to install the Gapps file on your device.
Step 4: Reboot your device
Once both files are installed, go back to the main menu of recovery mode and select \"reboot system now\". Your device will reboot and boot into Android Lollipop for the first time. It may take some time for the first boot, so be patient.
Congratulations! You have successfully downloaded and installed Android Lollipop on your Samsung Galaxy S2 using CyanogenMod 12.1 ROM. Enjoy! ec8f644aee
