Samsung Galaxy S2 I9100 users can still enjoy the perks of updating the Korean company's second generation flagship device. Since Samsung have stopped releasing updates for this gadget, custom ROMs such as AOSB can be used. According to Android Geeks, this custom ROM is designed by ProBAM team. Reportedly, AOSB Android 4.4.2 ROM packs the following features: multiwindow, HALO, RAM bar, audio stereo effect, incoming call dialog, xposed built-in, custom nav and ring bar, lcd density changer, DSP Manager, OTA Update support for new AOSB KitKat builds, and others.
Android Geeks listed the ways to prepare and install AOSB in your handset.
Before starting the installation you need to take a look at the preparation guide below:
- This guide works only with the Samsung Galaxy S2 model number I9100.
- Don't update any other devices with the files that you will find in this post, as you will brick the firmware.
- Your Galaxy S2 has to be rooted and running the latest CWM or TWRP Recovery image.
- If the latest build of either CWM or TWRP isn't installed on your phone, then you cannot flash any new KitKat custom ROMs.
- The tutorial will tell you to create a NANDROID ROM Backup and Factory Reset your phone.
- NANDROID ROM backup creates a full restore point for your device.
- Factory Reset wipes all data from system partition, but it leaves the internal and external sdcards unaffected.
- Factory Reset is required as you need to perform a clean installation of this new ROM.
- Save data from installed applications, SMS and other similar files using the Helium app for Android.
- Sync Contacts info with your Gmail account.
- The phone's battery power level has to be over 50%, so that the phone will not switch off while you're flashing the AOSB Project KitKat ROM.
- This guide is for advanced users, do not blame us in case you lose any data nor in case you brick the device.
- Read the entire post, don't skip any steps and you should be alright.
