    • The SlimBean stable ROM and instructions provided in this guide are meant for Galaxy S4 LTE GT-I9505 model only. Do not attempt installing the firmware on any other model, as you might end up bricking the device.
    • Ensure the device is factory unlocked and rooted with ClockworkMod (CWM) recovery or TWRP installed on it.
    • Back up important data and settings on the phone via one of the custom recovery tools such as CWM or TWRP to prevent data loss during firmware installation.
    • Ensure the device has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) during firmware installation.
    • Enable USB Debugging mode by navigating to Settings > Developer Options (if phone is running Android 4.0 or later) or go to Settings > Applications > Development (if running Android 2.3 or earlier). If the device is running Android 4.2, then perform the following steps:
        • Go to Settings > About Phone
        • Scroll down to the bottom of the screen and select Build Number
        • Tap Build number seven times to unlock or reveal hidden Developer Options. Now, select the checkbox to enable USB Debugging mode under Settings > Developer Options.

How to Install Android 4.3 Based SlimBean Stable ROM on Galaxy S4 LTE GT-I9505

    • Connect the phone to computer with original USB cable and copy the downloaded SlimBean Stable ROM and Google Apps zip files to the root folder on the phone's SD card.
    • Power off the phone and boot it into Recovery mode. To do so, press and hold Volume Up and Home buttons together and then simultaneously tap the Power button until the green robot icon with a triangle appears on the screen. This confirms entry into Recovery mode.
    • Before flashing the new ROM do the following steps in CWM recovery:

      > go to "advanced" and perform wipe dalvik cache
      > go to "mounts and storage" and format system
    • In CWM recovery, click Install Zip from SD card and select the ROM zip file copied earlier to the phone's SD card (repeat this step for installing Google Apps as well).
