Samsung is supposedly gearing up for an official release of the Jelly Bean Android 4.1 update for the Galaxy S3 on August 29th, and the Jelly Bean firmware that are getting leaked would suggest that Samsung is set to keep their word about the August 29th release. Now, another official Jelly Bean firmware – i9300XXDLH6 or simply XXDLH6 – has leaked for the Galaxy S3 which is available for manual flashing via Samsung’s oh so famous Odin program.
Keep in mind that this is a leaked firmware, so it might have some serious issues or bugs, which might make it unstable for every day use, so you should wait for the official update to come out if you’re not comfortable with manual flashing. But you can still try it out, as you can always flash back to an Android 4.0 firmware later if needed.
Let’s take a look at how the i9300XXDLH6 Jelly Bean Android 4.1 firmware can be installed on the Galaxy S3.
This guide to install Android 4.1 Jelly Bean firmware is compatible only and only with the international Galaxy S3, model number i9300. It’s not compatible with the US variants or any other device. Check your device’s model number in: Settings » About phone.

How to Install i9300XXDLH6 Jelly Bean Android 4.1 Firmware on Galaxy S3
- [Important] To be sure you do not lose any data, backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you. Backup all the SD card files, including camera photos, music, etc as well as those also might get erased during the flash as this is a leaked firmware.
- Download and install the software Kies on your computer, which will install the necessary drivers for the phone.
You can also download the drivers directly — download from here: 32 bit (x86) Windows | 64-bit (x64) Windows
- Download the i9300XXDLH6 firmware.
Download XXDLH6 Firmware | Filename: I9300XXDLH6_I9300OXADLH6_I9300XXLH6_BTU.zip
- Extract the I9300XXDLH6_I9300OXADLH6_I9300XXLH6_BTU.zip file to obtain the following files:
- Extract the contents of the Odin3_v3.04.zip file to a folder on your computer. Odin is the software we will be using to flash the firmware on the phone.
- Now, turn off your Galaxy S3 and wait for some 5-6 seconds after screen goes off to allow it to shut down completely.
- Then, put the phone into download mode. To do so, press and hold these keys together: Volume Down + Home + Power till the screen turns on. Then press Volume Up to enter download mode. You can flash a firmware only from download mode.
- Open Odin by double-clicking on the Odin3 v3.04.exe file obtained in step 6 after extracting Odin3_v3.04.zip.
- Important! Connect your phone to PC now. You should get the message “Added !!” under Odin’s message box in the bottom left.
If you don’t get this message, make sure you installed drivers correctly (using Kies or directly) as given in step 1. If it still doesn’t work, try changing to another USB port on the computer and also use the USB ports on the back if you have a desktop PC.
- Click on the PDA button in Odin, then browse to and select the file — I9300XXDLH6_I9300OXADLH6_I9300XXLH6_HOME.tar.md5 — you obtained in step 4.1 above. (Take care and do not select the .zip file you downloaded in step 3.)
- Important! Do not make any other changes in Odin except selecting the required files as given in step 11. Leave all other options as they are. Make sure Re-Partition check box is NOT selected.
- Now, click the Start button on Odin to start flashing the XXDLH6 Android 4.1 firmware on your Galaxy S3. When the flashing is complete and is successful, you’ll get a PASS message (with green background) in the left-most box at the very top of the Odin, and the phone will automatically reboot. When you see the Samsung logo, you can safely unplug the cable.
What to do if Odin gets stuck or doesn’t do anything: If ODIN: 1) gets stuck on setup connection, or 2) at any stage of this process after you’ve hit the Start button, and doesn’t seem to be doing anything, or 3) if upon completion of the process you get a FAIL message (with red background) in ODIN, then in all these scenarios, do this: disconnect the phone from the PC, close ODIN, remove battery for 4-5 seconds, re-insert it, turn phone on in Download mode again, and do the procedure again from Step 7.
- After you get the PASS message and the phone reboots, there are chances that it doesn’t boot properly and gets stuck either at some strange screen (3e recovery, actually) or maybe gets stuck at boot animation. Well, there is nothing to worry about that. All you need to do is do a “Factory Reset” from 3e recovery.
So, if your phone boots in 3e recovery (with black background and Android in the center of screen, and some blue text), just do a factory reset as said on steps 13.1 to 13.4 below. And if it’s stuck while restarting at boot animation, perform the following steps to make it boot properly. Remember that these steps will wipe your personal data like contacts, apps, messages, etc.
(Note: If phone has restarted, that is booted properly, you do not need to perform steps 13.1 to 13.4, these are only for those whose Galaxy S3 is not booting up/restarting after the flashing from Kies and getting the PASS in Odin.)
So, perform these steps for doing a Factory Reset:
- Boot into 3e recovery mode — just press and hold Home + Volume Up + Power keys together till you see the Samsung logo, and then let them go of keys to boot into recovery. Once you are in recovery mode, use volume keys to move the selection up and down and home/power key to select the option.
- Go to Wipe data/Factory Reset and select it. Select Yes on next screen.
- Now, go to Wipe Cache and select it. Confirm Yes on next screen.
- Then, select reboot system now to reboot the phone, which will now restart/boot properly.
