Install SlimKat Android 4.4.2 Stable ROM for Samsung Galaxy S2 I9100
SlimKat ROM team has launched their first build based on AOSP Android 4.4.2 for you to install on your Galaxy S I9100. This is a guide that is easy to follow and learn how to successfully install the custom ROM on your phone.
Use this post only if you’re planning on testing a KitKat ROM, don’t update your device if you’re thinking on using the new ROM on a daily basis. SlimKat is only in its first stage of development, which means that you might find some small bugs during testing. Learn more about this release by visiting the developer’s web page here or go to XDA thread here.
Before starting the installation process of this new ROM you will first have to take a look at the preparation guide below:
- Use this tutorial only with the Samsung Galaxy S2 model number I9100.
- this guide will not work with any other smartphones nor devices.
- your phone has to be rooted and running the latest CWM Recovery image.
- TWRP will also work.
- note that you have to update the custom Recovery image to its latest version before starting installation of this new ROM, as otherwise you cannot flash a KitKat custom ROM.
- Backup data from installed applications using Helium for Android app from here.
- Sync Contacts info with your Gmail account.
