How To Install Android 4.4.2 AOSP NeatROM On Samsung Galaxy S2 (I9100)

We don’t know much about AOSP NeatROM, but version 2.4.1 from XDA Developer _Sale_ recently became available for the Samsung Galaxy S2. Based on Android 4.4.2 KitKat, the ROM is reportedly relatively stable, with a number of unique tweaks and customization options.

This guide will walk you through the installation process. As always, Androidstray assumes no liability for the firmware installation. Proceed with caution.

Before Getting Started

This guide is intended only for Galaxy S2 handsets with an I9100 model number. Flashing any other device through this method may result in a bricked phone.

You will need to be rooted and running ClockworkMod.

As always, you want to backup your device and charge it to at least 80 percent. Finally, enable USB Debugging mode by navigating to Settings -> Developer Options.

Installing AOSP NeatROM (KitKat 4.4.2) On Samsung Galaxy S2

1) You’ll need to download the ROM, which can be found here, as well as the Google Apps package

2) Using your USB cable, connect your Galaxy S2 to a computer and copy the AOSP NeatROM and Google Apps package to the root folder of your handset’s SD card.

3) Boot into Recovery mode by holding down Volume Up, Home and Power buttons together.

4) Using CWM recovery, perform “wipe data/factory reset,” “wipe cache,” “wipe dalvik cache,” and finally, format the system through the “mounts and storage” submenu.

5) Navigate to “Install Zip from SD card” within CWM recovery and navigate to the ROM you copied earlier, which will be in a .zip archive. Once you select the ROM, your Galaxy S2 will begin to install AOSP NeatROM and the process should take five minutes or so to finish. Do nothing until the installation is complete.

6) Repeat Step 5 to install Google Apps.

7) Once the ROM is loaded, navigate to “Reboot System Now” and allow the phone to restart. Once it boots back up, you are officially running AOSP NeatROM’s 4.4.2 KitKat custom build. Kudos.
