Samsung Galaxy SII owners have been tossing and turning ever since the company first announced that the Jelly Bean update will soon be available for all customers. Although the update is not ready yet in all regions, you still need to get prepared for the moment everyone has been waiting for. Here are the steps that you will need to accomplish in order to correctly install the Jelly Bean update.
AOKP ROMs, also known as Android Open Kang Project, is the only update that may be found and installed on Galaxy SII devices. The project has had very good results in the past as AOKP ROMs are very fast and they rely on the AOSP release of the new Android operating system. In case you are planning to use an AOKP build ROM, you need to make sure first that your smartphone is a Samsung Galaxy S2 I9100. The update will not work with other versions, so do not try to install the program unless you are certain that you have the same model.
The phone must be rooted before initiating the installation process. Also, make sure you protect all the data you may have previously stored on your device as the manufacturers will not grant you warranty coverage if the AOKP ROM update goes wrong. For that, you will have to create backup files containing the SMS and contact details you have stored on your smartphone.
Connect the phone to your computer using a USB cable and copy the downloaded zip files of Android 4.2.2 Jelly Bean and Google apps on the SD card, more specifically in the SD card root folder. Turn the smartphone off and disconnect it from the computer. Switch the phone on in the recovery mode by pressing and holding the Volume Up, the Menu and the Power buttons.
While in the recovery mode, access the zip file using the Power button and select the “flash zip from SD card” option. Install the Android 4.2.2 zip file and allow the installation process to finish. Access the Google Apps zip file and repeat the same steps as with the Android 4.2.2 file.
You must boot the smartphone so you can rest assure that the installation was successful. The first boot will probably take around 5 minutes, so don’t get impatient if you think it takes too long. Once the device is turned on, go to Settings and then, About Phone to verify whether the installation was successful or not.
