Samsung Galaxy S3 Android 4.1.1 Jelly Bean Firmware Leaks; Here Is How To Install It!
By on August 16th, 2012

It was just yesterday that a video of the leaked Android 4.1.1 Jelly Bean firmware for the Galaxy S III was uploaded on YouTube by AndroidMX. The leaked firmware (LG4) provided further proof that Samsung is hard on releasing Android 4.1.1 Jelly Bean for its latest flagship handset.

Well, if you cannot wait for the official Jelly Bean firmware to be available from Samsung, the folks over at SamMobile have you covered. They have managed to get their hands on the LG4 firmware that was demonstrated by AndroidMX on YouTube yesterday.

Below is a step by step guide on how to install the leaked LG4 Jelly Bean firmware on your Galaxy S III -:

Please make a backup of your data before flashing the firmware below. Also back the contents of the internal memory card, since flashing the firmware may wipe the phone’s internal memory. Also, make sure you are running a Samsung based ROM prior to flashing this ROM, and not any AOSP based ROM like CM9 etc. 

Step 1: Download ODIN from here, and the leaked LG4 firmware from here. Extract the contents of the firmware zip file inside a new folder on your desktop.

Step 2: Start ODIN and  click on the PDA button. Then select the ‘CODE_I9300XXDLG4…tar.md5′ firmware file that you extracted inside a new folder on your desktop.

Step 3: Reboot your Galaxy S3 in Download mode by switching it off, re-inserting the battery, and then pressing the Volume down + Home + Power button simultaneously. Skip the Custom OS warning by pressing the Volume Up key.

Step 4: Connect your SGS3 to your PC, and wait for ODIN to detect it. When ODIN detects the phone, it will display a random COM No: inside a glowing yellow rectangle. Press the Start button and wait for ODIN to flash the firmware.

Once the firmware is flashed, your phone will automatically reboot. If it enters into a bootloop, boot into Recovery mode by pressing the Volume Down + Home + Power button and do a wipe data/factory reset.

I will highly recommend newbie Galaxy S3 owners to stay away from flashing this firmware. The official OTA update from Samsung is just a couple of weeks ago, and will be much more stable than this leaked firmware.
