Looking to get the latest version of Android, 4.1 Jelly Bean onto the Samsung Galaxy S3 for AT&T, but don’t want to wait for Samsung’s official update? Pay attention, because below are the instructions on installing CyanogenMod 10 (CM10) for the Galaxy S3, courtesy of CyanogenMod.

Still, if Project Butter and Google Now are desirable features then read on for installing CyanogenMod 10. Bear in mind that there is a risk of damage to your device and is not responsible for consequences users could experience.



Download the CM10 ROM for the AT&T Galaxy S3 from the XDA-Developers forum thread. Then download the Google App package, and copy the ROM and App package onto the SD card.

Now, switch off the Galaxy S3 to boot into ClockworkMod recovery. There are 2 methods you can use to get into the recovery console.

1. Open up RomManager and go to the option that states “Reboot into Recovery”

2. By pressing Volume Up, the Home button, and the power button together once the phone has been powered off will boot into the recovery mode. When the screen turns on, stop pressing the buttons. Wait a moment and a list of options will be presented; navigation is done through the volume buttons (up/down) and selecting options is done via the Home button.

Navigate to “wipe data/factory reset,” select the option, and then “Yes” to confirm. After the aforementioned information is wiped, choose the install zip option from the SDcard. Navigate to the ROM file, and select “Yes” again to begin installation.

Once installation is complete, choose the zip file again and the Google Apps package “” file. After being selected, return to the main recovery menu and select the option to reboot.

Afterwards, CM10 will be installed on the Samsung Galaxy S3. There are 2 other flashable packages you will need to install to make your phone more usable. As at this time the camera and text messages are not working as they should.

1. – This allows the camera to actually work. If you do not install this package everytime you go to something that utilizes the camera you will get “Can not connect to camera”

2. – this allows messages to be send as text messages and not as Multimedia messages.

Once all of these items are installed you can enjoy the smoothness of Jelly Bean. *Note I used this rom for a couple of days and the battery life was not good enough for what I needed. It ran dead in matter of hours. Once they get the stability of CM9 ported over to the CM10 Rom I will be using this rom again.
