Even though there is no Android 4.4.2 KitKat official firmware available for the T-Mobile Galaxy S2 you can still flash the latest Android OS on your smartphone. How? By installing a custom ROM of course. In that matter I will show you how to update your T-Mobile Samsung Galaxy S2 to Android 4.4.2 firmware by installing Alpine custom ROM software into your Android device. Don’t worry as the tutorial can be easily completed even by a newbie – don’t perform things without consulting the guidelines from below though as you don’t want to mess things up.
Even though the Alpine ROM is not a popular Android 4.4.2 KitKat based custom ROM, the firmware is quite cool as it is featuring great stuffs. Furthermore, Alpine is based on other platforms like CM11, or AOKP so you will get the best features that are being available on the Android market. Also, Alpine system has been optimized especially for your T-Mobile Galaxy S2 which means that the update is stable, runs without lags and also comes without bugs and other related problems and issues. Therefore, don’t hesitate and test the ROM by yourselves.
Since it is a custom ROM, Alpine can be used for improving the performances of your Galaxy S2. By using its features and capabilities you can easily bump the speeds, personalize the looks, upgrade the battery life and so on. You will also be able to access the internal system, remove bloatware, overclock your Android device and lot more. Of course, don’t forget that a custom variant of Android 4.4.2 KitKat OS will also be installed on your T-Mobile Android smartphone.
It is important to make it clear that Alpine is not an official update released by T-Mobile for Galaxy S2. Alpine is only based on official Android 4.4.2 KitKat OS and it is actually developed by third party devs – those of xda-developers. Because of that, this installation procedure is also unofficial. Also, for being able to complete the flashing procedure, first you will have to prepare your device – just apply the pre requisites from below and everything will be fine.
- Root your T-Mobile Samsung Galaxy S2.
- Install a custom recovery image on your smartphone.
- Backup your device.
- Also make a Nandroid backup.
- Make sure that you can use a computer or notebook.
- On the same first of all deactivate the antivirus and any other security protection.
- Before going any further on your phone enable the USB debugging option by going to “menu – settings – developer options”.
- Furthermore, check the battery status of your device; if you notice that there is less than 50% power left, plug in the charger.
- Use this tutorial only if you own the T-Mobile variant of Samsung Galaxy S2 – Alpine custom ROM based on Android 4.4.2 is compatible only with the mentioned Android smartphone.
Root access must be gained for unchaining the system of your Galaxy S2. Do that because Alpine firmware needs to access some inbuilt files that are located on the Android system. Be careful as gaining root access is a complex and unofficial operation and by applying the same the warranty of your device will get void – you can restore the warranty only by downgrading to stock Android Jelly Bean OS. Then, after completing the root, you need to flash the latest version of CWM or TWRP recovery – use one of these apps as Alpine OS has been tested only with the same.
The backup is quite important as on the update operation a wipe will be required – you will probably lose everything that’s saved on the internal storage memory of your phone. So, use suitable backup and restore apps and save the EFS folder, the contacts list, call logs, market apps, personal data and accounts and everything else that’s important for you. You can use compatible apps from Google Play, or you can also use dedicated backup tutorials.
The rest of the pre requisites are general ones, but don’t head to the proper tutorial without completing the same. It is important to apply all the steps from this guide; else you can mess things up and you can end up in bricking your Android smartphone.
