The new project started by XplodWild, Chainfire and Dees_troy called OmniROM has reached the “Nightlies” stage. Now you can finally update your Galaxy S2 I9100G with one of the best Kitkat custom ROMs. Read the info in this article and you’ll learn how to successfully get the latest KitKat features on your phone.
OmniROM is based on Android 4.4 KitKat AOSP, which means that it contains all of its default features as well as adding some of its own. The new features added by OmniROM are as following: non-obtrusive incoming call alert, flippable quick settings, multi-window, multi-workspace, visual UI tweaks, DSP Manager enhanced, per-app permissions controls, etc. There are tons of other small tweaks that will allow you to use the Nightly build on a daily-basis.
OmniROM is still in its development stage and you might find errors or bugs while testing it. You can continue updating it with new versions using the download link listed in step 1 of the tutorial.
In order to make sure that you correctly flash this new custom OmniROM Android 4.4 Nightly for your device you will first need to read the guidelines below:
- Use this post only with the Samsung Galaxy S2 model number I9100G.
– this is the TI OMAP variant of Galaxy S2.
– the Galaxy S2 I9100 Exynos variant isn’t supported by this tutorial.
– do not attempt to update any other Android device with the ROM files you find in this article.
- The Galaxy S2 I9100G has to be rooted and the CWM Recovery should be installed on it for you to be able to flash OmniROM KitKat custom ROM.
– CWM Recovery has to be updated to its latest version, as otherwise you cannot complete the installation.
- A Factory Reset is required for your device before starting the OmniROM KK Nightly install process.
– the Factory Reset removes data from system partition.
– Factory Reset doesn’t delete contents stored on the internal nor external storage parts of your device.
> this step can be found in the tutorial.
- Backup data from installed apps using Helium tool — Google Play Store link here.
- Backup APN Internet Settings and SMS text messages with these Android apps: SMS backup & restore | APN Settings Backup & Restore.
– root access will be needed for some of these applications.
- Sync Contacts data and People details with your default Gmail account.

– by syncing such data you will ensure that no save phone numbers are lost.
– after the installation of OmniROM is completed you will need to make sure to enter the same Google Account, so that all phone numbers and Contacts info are synced with your phone.
- In the tutorial you’ll find the NANDROID ROM Backup step, don’t skip it.
– it will set a restore point for your phone, one that can be used in case the new smartphone doesn’t boot in normal mode.
- Enable USB Debugging from Developer Options menu.
- This is a guide for advanced Android users who want to test custom Android 4.4 KitKat custom ROMs.
- Read the entire tutorial and make sure not to skip any steps that I’ve listed in the tutorial.
