Preparation


If you are using Windows, the USB driver for the Galaxy S4 can be downloaded here. It is required for working with adb or flashing RTAndroid from Windows.

Installing Recovery


This guide describes how to install a custom recovery for the Galaxy S4. This is a necessary step for installing RTAndroid, as the native device does not allow for installation of custom ROMs.

Warning: The following instructions may damage your device permanently and/or void its warranty. We take no responsibility for any damages caused.

All steps should be performed on a Windows machine, as the current versions of Odin and Heimdall for Linux seem highly unstable.

  1. Make sure that the battery is charged over 60% and turn off the phone.
  2. Download Android SDK tools. It is sufficient to download SDK Tools Only, which becomes visible when opening the drop-down menu VIEW ALL DOWNLOADS AND SIZES.
    1. Run the installer you downloaded. At the end of the installation, accept opening the Android SDK manager. After the manager has opened, select and install the Android SDK platform-tools, other packages are not required.
    2. After the installation has finished, the folder platform-tools is available in your SDK installation folder. We will need the adb executable in other tutorials.
  1. Make sure you have the correct USB driver installed.
  1. Download Odin 3.07. We will later use this program to upload the custom recovery to the phone.
  1. Download correct ClockworkMod Recovery for your device. We will replace the factory recovery with this one. You don't need to extract this file.
  1. Put your phone into download mode by holding Volume Down + Home + Power key at the same time. You should get a screen showing a warning and asking to continue, press Volume Up to continue.
  1. Open Odin
  1. Connect the phone to your PC. In Odin, the ID:COM box should turn light blue.
  1. Click on 'PDA' button and select the downloaded ClockworkMod file.
  1. Click 'Start'. The process will start and give you a PASS indication above the ID:COM box if it installed the recovery successfully.
