Although the KitKat 4.4.2 KOT49H over the air update should already be on the go and ready to be installed on your Galaxy S4, there’s a slight chance that some of you might have missed it – some of the reasons might be:
- regional limitations
- root access
- S4 running a custom ROM
So if you want to revert back to stock firmware and manually install the official KitKat 4.4.2 KOT49H update on your Galaxy S4 Google Edition, here’s a simple way to do it.
So basically, you’re not going to install the KitKat 4.4.2 official update like you do on an International variant of the S4 (if you’ve tried it already) – instead, this is going to be like installing a custom ROM (except you’ll install the official firmware); you’ll have to download the KitKat 4.4.2 official OTA image and Gapps zip file file from the links given below, move them to your S4’s root storage and then flash/install them via your custom recovery mode.
The process reviewed above is applicable if you’re coming from a custom ROM. However, if you’re coming from Stock – you’ll need to do all the pre-requisites e.g root your S4 Google Edition. So if you’re running a custom ROM on your device, skip to the last step and install the KitKat 4.4.2 official OTA update.
Preparations and things to keep in mind
- This is a stock KitKat 4.4.2 firmware ROM for Galaxy S4 Google Edition.
- This guide along with all the files we’ve linked are applicable to only the Google Edition version of the S4 (I9505G), don’t go off trying to flash this on an international variant or anything.
- You’ll need to root your S4 and Install a Custom recovery (CWM) on it – refer to Step 1 to learn how.
- Make sure you have the USB data cable that came with your device.
- Turn on USB debugging on your S4 Google Edition by going to Settings > About Phone > Tap on build number a few times and a message should come up affirming that USB debugging has been enabled.
- Charge your S4 Google Edition to at least 85% or it might turn off during the installation.
- Make sure you have all the drivers installed on your computer to support Galaxy S4 Google Edition.
You’ll be performing several wipeouts before the ROM installation to avoid any overwrites – so do yourself a favor and backup all your important files, photos, songs, videos etc. You can also use the default ‘Backup and restore’ option from settings to sync your contacts and mail.
- Download Android SDK and move it into your C: (C drive) – open it, it should contain the adb and fastboot files.
- Download the Chainfire Root file and move it into the same place where the adb and fastboot files are located (inside the C:\adb\sdk\platform-tools folder).
- Download the CWM custom recovery image and place it in that folder too.
- Download the Official KitKat 4.4 firmware ROM zip file to your desktop (don’t unzip/extract it).
- Download the KitKat 4.4 Gapps zip file to your Dekstop (don’t unzip this either).
