Galaxy S2 has been a great Android smartphone and even though there won’t be any official OTA updates released for this device, its users can still enjoy everything that’s new on the Android KitKat platform. In order to prove you that I know what I am talking about, during the guidelines from below I will be showing you how to update the AT&T model of the Galaxy S2, aka Skyrocket, to Android 4.4.2 KitKat firmware, by flashing the latest version of AOKP custom ROM into its system.
But in order to install AOKP firmware on AT&T Galaxy S2 Skyrocket you first have to read the lines from below, where I have described more details related to this new Android 4.4.2 based update and related to the flashing procedure of the same. As you know, a custom ROM represents a free aftermarket distribution of Android OS, which in our case is developed by third party devs. Unfortunately, this is not the official AOKP firmware, so this Android 4.4.2 OS is coming with minor stability lags and bugs. Don’t worry though, as those who have tested AOKP of Galaxy S2 Skyrocket had declared that the firmware is good enough for daily use.
AOKP is not an official update, so this Android 4.4.2 KitKat ROM has nothing to do with Samsung or with Google. Also, the ROM is coming with extra and stock features, which can’t be found on the default version of Android OS. With these features, your Galaxy S2 Skyrocket will perform better than before; you will be able to receive more power, improved speeds, enjoy a better web browsing experience, an upgraded battery life and a redesigned Android 4.4.2 KitKat firmware – AOKP will be featuring its own looks which are different from the stock ones.
Other than that, AOKP is one of the most appreciated custom ROM and it is used by many Android users as the firmware is compatible with almost all the Android smartphones and tablets out there. So, if you want to flash the same on your AT&T Galaxy S2 Skyrocket, do complete this step by step guide. In order to do so, first you will have to prepare your device for the installation procedure that will shortly follow. After all this is a manual update process, which must be considered risky and complex – don’t perform things without reading the lines from this tutorial.
As you might know, you can’t go any further with this operation unless your phone is rooted. If not, you should use a compatible guide and root your Galaxy S2 Skyrocket. By gaining root access you will remove the factory and default restrictions from your smartphone, this being the first thing to do for preparing your device when considering in updating with a custom ROM firmware such as AOKP Android 4.4.2 software. After rooting your AT&T GS2, resume the lines from below.
A custom recovery image must be installed on your phone. This tool is extremely important for us as the same will be used on the flashing operation – you can’t complete this guide without using a custom recovery image. Install the latest version of CWM or TWRP recovery on your Galaxy S2 Skyrocket as the AOKP Android 4.4.2 firmware can be flashed only by using the mentioned tools.
When gaining root access you will complete the first unofficial operation. So, at that time the warranty of your smartphone will get void. This can’t be avoided, so if have doubts, maybe the best will be to stop going any further. Anyway, you can choose to restore the warranty whenever you want; for doing that you will have to downgrade your AT&T Galaxy S2 to stock Android firmware, or of course to apply a un-root procedure that is compatible with your Android device.
As usual, when dealing with risky operations, it is recommended to backup the data which is saved on the internal storage of your phone. The best is to backup at least the text messages, the call logs, the market apps, the EFS folder, the contacts list and your personal info, accounts and data. Furthermore, since a custom recovery image is installed on your device, you should consider in using the same for saving the current ROM – you will be able to restore the firmware without using a complex tutorial like the present one.
A computer, your AT&T Galaxy S2 and its USB cable are being required. On both, smartphone and computer you need to deactivate the antivirus, antimalware and any other security program, as these tools might interfere with the update operation. Your device must stay “alive” during the flashing operation of AOKP firmware so, if you notice that there is less than 50% power left, before going any further charge your Galaxy S2. On the same time, since you will have to connect your handset with your computer, on your phone enable the USB debugging option: go to “menu – settings – developer options”. Do note that this tutorial is compatible only with the AT&T model of the Samsung Galaxy S2 – Skyrocket – so don’t use the steps from below in other situations – you can end up in bricking your smartphone or tablet.
