Guide to rooting your Samsung Galaxy SIII 4G - I9305 - Optus firmware

Hi Everyone, so I have been spending the last 3 or 4 days trying to work out how I can gain root access on my I9305.

The only thing I was able to find was horror stories of people bricking their devices...

After a lot of research (and quickly learning how android OS images work!) I was able to generate my own custom rom for the i9305.

Things to note:

THIS IS FOR THE AUSTRALIAN I9305 (OPTUS) SGSIII 4G ONLY! DO NOT FLASH THIS IMAGES TO ANY OTHER DEVICE!!!

I will not be responsible for any damage done to your device or PC(s), flashing custom rom's can be risky, so please be careful!

This will most likely wipe your phone, so make sure you backup first!

This rom is 100% stock, it does not remove any optus apps or branding,

This will NOT give you the yellow triangle at boot

the MD5 sums for the files are below

I9305_XXALI5_root.z01

eefe9d3736e69542603ccebd3607c300
I9305XXALI5_I9305OPSALI5_I9305XXALI5_HOME.tar

to check these, download MD5summer from www.md5summer.org

How did I do it?

I originally created an insecure boot image, flashed it to the device and tried to gain root via adb, however this did not work, so I unpacked the system image file, added the nessicary binaries and repacked it.

Once I had done this, I was able to flash the system image with odin.

What do I need to do?

1. Download Odin (you might be able to use heimdall, however I have not tested this!)

https://hotfile.com/dl/173880315/eee04eb/Odin3_1.85.zip.html

2. Download the image (3 parts, zip files)

3. Unzip Odin to an easy to access place (such as your desktop)

4. Unzip the image file to the same directory.

Use either winrar (www.rarlabs.com) or 7-zip (www.7-zip.org) to extract the multi-part zip.

5. Boot your SGS in to download mode
(power off... then press and hold the power + volume down + home buttons at the same time)

6. Connect your phone to your PC using the cable that came with it.
If you are using a laptop make sure you connect it to a port on the machine not the docking station (if you have one). If your machine has USB3 try to avoid using the USB3 ports.

7. Open the Odin application
Make sure your phone is detected, there will be a yellow square in the top left corner (see below screen dump)

8. Make sure it looks similar to the below screen (same options ticked, the .tar file in the 'PDA' section)

9. Press start and wait. Your phone will be flashed and reboot when it is finished.

10. That's It, once the phone has booted you will have root access.

I am willing to bet it will work on any GT-I9305... Even the european one As its exactly like someone flashing A I9300 to a I9300 from australia or a I9300T they all work together I have done it perfectly without a problem.

So I would say All I9305 are the same Overseas and australians... BUT IT HAS TO BE I9305 Model number

Woohoo, it worked! Thanks a ton. Confirmed working on my I9305 from Optus.

Unfortunately my upload speed is rather slow so those waiting for an alternate download link will have to wait for a while. I'm only uploading part 1 tonight (available in 80 minutes) and will upload part 2 and 3 tomorrow morning.

Dial *2767*3855# in the stock dialer, that is the quickest way.

but you will get NO warning, the phone will just begin to erase itself, so make sure you are ready!

    Hey anyone know a way to remove the Optus boot animation and shut down?
    Click to expand...
    Click to collapse

    hey mate.

    download the following zip file

    https://hotfile.com/dl/174393434/730bdb5/bootlogos.zip.html

    then copy bootsamsung.qmg to /system/media with permissions of rw-r--r--
    also copy shutdown.qmg to /system/media/video/shutdown with permissions of rw-r--r--

    this will give you the stock samsung startup and shutdown logos.

    I will be putting these in to a rom I am working on.

    Would you mind elaborating on this a little?

    I had intended on doing the same thing but from my own brief research I couldn't determine which files to include in the repack or exactly where they should go.

    I am assuming you have packed an su binary, but which version and from where?
    I've also assumed that you used a 'nix box to pack and repack with simg2img or something similar...

    I'm not lazy.. honest :) I have a newborn and its so damn hard to find the time to research or play with my new phone at the moment... heh.

    oh... and is it yaffs or ext4?

    Cheers
    Click to expand...
    Click to collapse

    I used an ubuntu VM to create the image, and then odin on windows to flash it. However you could use heimdall on linux too.

    the system.img file is EXT4.

    you need the su binary and a root manager like supersu

    su goes in /system/xbin

    root manager in /system/app

    mkext4 and simg2img to extract/repack the image

    Hi Mick

    Have followed you guide for rooting the Samsung GT9305 G4 Optus phone. Odin seems to do its thing and then reboot the phone but the phone just stops at the stage where it displays a flashing SAMSUNG logo. I have tried this a couple of times with the same results. Any ideas as to what might be going wrong.

    See attachment for Odin
