Install CyanogenMod 9 Android 4.0.4 ICS On Galaxy S III GT-i9300 [How-To Tutorial]

The latest version of popular custom ROM CyanogenMod now supports Samsung’s recently released Galaxy S III (GT-i9300). Those of you interested in checking it out can follow our detailed, step-by-step guide right after the jump!

The news comes straight from XDA-Developers – a popular forum for Android enthusiasts, developers and modders – in the form of a thread posted by Team Hacksung developer XpLoDWilD in which they discuss the state of CM9 for the Galaxy S III, what’s working and what’s not and, of course, how to get it working.


DISCLAIMER: Redmond Pie will not be held responsible for any damage incurred to your device as a result of following this guide. Follow at your own risk.

Before you dive in, please keep in mind a couple of things. Firstly, this will void your warranty. Secondly, there are a few minor bugs that you should know of: FM radio does not work, using the flash in Camera app may cause it to crash and trying to wake up the device using volume keys “may” not work, so there you have it.

Step 1: Root your Galaxy S III and flash ClockworkMod Recovery to it.

Step 2: Download the latest nightly build of CM9 [CM Downloads] and Google Apps for CM9 []. Transfer both to directly under /sdcard on your Galaxy S III.

Step 3: Shut down your device. Boot into ClockworkMod Recovery by holding the Volume Up + Home + Power buttons.

Step 4: Take a nandroid backup. This will come handy later on if you wish to revert back to previous setup.

Step 5: Navigate to install zip from sdcard > choose zip from sdcard > [CM9 .zip file you downloaded in Step 2].

Step 6: Similarly, you must flash Google Apps.

Step 7: From ClockworkMod’s main menu, perform wipe data / factory reset.

Step 8: Choose reboot system now from the main menu.

If you followed the steps correctly, your device will now boot into CyanogenMod 9 based on Android 4.0.4 ICS. The developer advises not to reinstall apps using Titanium Backup. Also, if your Wi-Fi doesn’t work, remove from /data using a root-ready file explorer (e.g. ES File Explorer).
