[Galaxy S III I9305 (4G LTE + 2GB RAM) Android Deve] droido123:
FOR NOOBS only

This is written by a noob for other noobs. It contains a set of very detailed instructions and is compilation of varies inputs from lyriquidperfection, audsim, btemtd, and nnnevvv. Without them I would be nowhere. I hope this guide, despite being very detailed, can help others so they don't have to hunt and pester devs for answer. This guide is only an expansion and extrapolation of this post which was kindly created by btemtd.

*

It also involves other work from the developers I credited above.

*

This guide is NOT for you if you have:

1) Bricked your phone

2) have an i9300

3) lost your IMEI

4) installed a custom ROM

5) already have CWM or SU installed.

*

Please remember it is only an expanded set of instructions built upon btemtd original work. Its only intention is to help get it done, right, without using up other's time. If the thread creator or OP ed suggests I amend or remove anything please let me know.

Pre-install instructions:

1)	Your device is NOT bricked and is running stock OEM i9305 installed software with details for the device posted at the end of this reply.

2)	Prior to doing ANYTHING you can Dial *#7284# on device and can see the 'Qualcomm USB Settings' button

3)	KIES drivers installed and i9305 to PC works in KIES application OR you have verified that USB drivers work fine for PC to device

4)	You have downloaded on to your PC the Odin3 v3.04. application.

5)	You have downloaded the I9305_CWM_Recovery.tar.md5 file to your PC.

6)	You downloaded the CWM-SuperSU-v0.96. zip file and stored it on the device’s internal memory card. You can store it directly on the device’s INTERNAL SD card (don’t worry, CWM will allow you to navigate to it).

7)	You don’t care about losing any of the media or pictures or applications (whatsapp) installed on my device as these can all be reinstalled later on.

8)	Battery is charged to 80 percent or more

9)	Solid dual use power and data cable tested and working.

10)	Back up all of the contacts to SIM Card in case Data wipe.

11) You are okay with warranty being void and binary counter reset being added

Installation procedure

1) Get coffee

2)	Install the latest version of Samsung KIES and check that complete cable communication works and that all drivers on the PC are installed. Confirm that KIES communicates with device on PC. DO NOT update your device using KIES to the latest Samsung or Android software.

3)	install QPST v2.7.378 program on your PC. The QPST software is a qualcomm product and is a diagnostic tool that has a variety of subtools that you can use to test, manage and edit the form factor device. Click the setup.exe file and follow instructions. This is a qualcomm product and it is not complicated. A user manual (in case you feel like exploring) is available in .pdf.

4)	Dial *#7284# on your device to access DeviceUtil and select 'Qualcomm USB Settings' at the bottom. Now scroll down and select 'RNDIS + DM + MODEM' and press 'OK' to return to the previous screen. Now press your 'Back' key to exit DeviceUtil. Your device is now in DIAG Mode.

5)	Connect your device to PC via USB. Note, it may showing “loading drivers” on your PC. Wait for USB drivers to load and install.

6)	Find the QPST application on your PC and navigate to the 'QPST Configuration' menu. Select it and navigate to the 'Ports' tab. Press 'Add New Port...' button. Select the COM Port that has 'USB/QC Diagnostic' next to it, change the Port Label name (if you wish to) to 'Samsung GT-I9305 diagnostic” then press 'OK'. You should now see your device listed in the 'Ports' tab and the 'State' should indicate 'Enabled'. Close this QPST application.

7)	The next step will help you to BACK UP the IMEI/NV Data.

8)	Go back to the QPST application Folder and navigate to the 'Software Download' application and then select the 'Backup' tab. You will need to select and name the file. I chose “i9305-qcn-back-up-file.qcn”. Press the 'Browse' button and select a Save Location for your QCN File. Press the 'Start' button and wait for it to finish. DON’T TOUCH YOUR DEVICE during this process. This will back up all your devices NV Items and save them to the QCN Backup File you just named. The resulting QCN Backup File should be about 250KB in size. The QPST application will show the backup has been completed. Verify that the file was actually backed up by looking in the directory to where you selected to store it. Then close the program.

9)	The next step will help you to check to RESTORING IMEI / NV Data:

10)	Go back to the QPST application Folder and navigate to the 'Software Download' application and then select the ‘Restore’ tab. Press the 'Browse' button and search for the QCN Backup File you created (remember I named mine “i9305-qcn-back-up-file.qcn”). Press the 'Start' button and wait for it to finish. This will restore all your devices NV Items from the QCN Backup File. Your IMEI / NV Data should now be fully restored. Dial *#06# on your device's keypad to check your IMEI is restored. It should show your 17 digit long IMEI number on screen. Write it down and store for future purposes in case you need to recall it one day.

11)	The next step is to Restore the USB Settings after you have performed the above QPST Backup / Restore procedure. Dial *#7284# on your device to access DeviceUtil and select 'Qualcomm USB Settings' at the bottom. Now select 'MTP + ADB' and press 'OK' to return to the previous screen. Now press your 'Back' key to exit DeviceUtil. The device will reboot as you ask it to save and reset. Your device is now back to default USB operation.

12)	Exit the QPST application.

13)	The next step is to install ODIN which you will use to flash the CWM files from your PC to the device.

* Note that ODIN packages can be device specific. For the GT-i9305 I used “Odin3 v3.04.exe”. Navigate to where you have stored the ODIN application and select “Odin3 v3.04.exe” file and double click. ODIN will open.

NOTE: ODIN will not self install on your computer like a standard-install.exe folder. You will need to run the “Odin3 v3.04.exe” file every time to open ODIN up. Forgive my noobness for not knowing what the name of this procedure it.

14)	Search for the ‘ I9305_CWM_Recovery.tar.md5 ‘ file you have downloaded previously in the “pre-install” instructions. For logistics purposes you may wish to drag and drop this file from its current storage location over the ODIN folder directory.

15)	If KIES is running shut it down or suppress it on your PC.

16)	The next step will involve “installing” the ‘ I9305_CWM_Recovery.tar.md5’ file. Actually, this is just a “module” that is intended to “replace” the stock recovery module. To do this, you will need to first set up your device to boot in what is called the “download” mode. To do this you must: POWER off the device first. Then after power is completely off, PRESS and HOLD the ‘power’ + ‘volume down’ + ‘home’ buttons all at the same time. I suggest that you start by pressing the “volume” + “home” buttons first instead of pressing the “power” button as you may inadvertently just power the device up (instead of booting it up into “download” mode). If you did it right you will boot up in “download” mode and Android will then ask if you if you “want to download a custom OS”. You will confirm “continue” by pressing the volume up key.

NOTE: it’s possible your PC computer may want to install device driver software. If so, just let it install and wait for it to finish.

NOTE: to navigate the menus in “download” mode (and also in “recovery” mode) you should use the VolUp / VolDown to go “up” or “down” the menu. Press the “power” button to select items (kind of like a “go” or “enter” function).

17)	Now Connect your device (make sure battery is at least 80% charged) to your PC ( it is preferable to connect directly to the computer and not through a USB HUB or port replicator).

18)	Open the ODIN application by navigating to the Odin3 v3.04.exe file . Make sure your device is detected and you should see a blue (older models may show yellow color) square in the top left corner.

NOTE: Make sure only the “auto-reboot” and “f reset time” boxes should be checked in the ODIN Application.

19)	Click on the box next to “PDA”. And then click the “PDA” and navigate to the area where the ‘ I9305_CWM_Recovery.tar.md5’ file is stored. Select it and it will auto populate into the ODIN application. Then, on the ODIN application, press “start”. You will see a series of command actions showing in the ODIN Application which should show the status. Upon completion it should show that CWM was installed in the ODIN application. You may have to repeat this process once again as CWM may not “stick”.

20)	There has been considerable debate about different units requiring the battery to be pulled due to the fact that some factory units have been shown to reboot back into its own factory state and therefore exclude the CWM file that you just tried to install in the previous steps. I read of many users who were experiencing this problem. See For further reading please see: http://xdaforums.com/showpost.php?p=32235061&postcount=1 to show how to deal with and manage this problem. I, along with another user that I confirmed with, DID NOT have to do the battery pull method. Why? Well, I think that some factory models require this process and others do not. My device (specifications at end of post) did not require it. Also, the problem may have been created by user’s updating their device software through the KIES application which I recommend not doing until the device has been rooted and CWM and SU installed in this process.

21)	After instructing ODIN to install the ‘ I9305_CWM_Recovery.tar.md5’ onto the device the device should reboot. If it does not reboot after awhile you can power down your device. What will happen? Well, you have either successfully installed the ‘ I9305_CWM_Recovery.tar.md5’ file or your device has reverted back to the factory restore option. You shouldn’t have much risk of bricking the device during this step. The key is to get the ‘ I9305_CWM_Recovery.tar.md5’ file to stick during the “download” process. If it does not stick you will need to refer to the thread For further reading please see: http://xdaforums.com/showpost.php?p=32235061&postcount=1 as to how to employ the “2 different battery pull during the reboot process” methods he suggested (again, fortunately I did not need to do this).

22)	Now you need to put the device in “recovery mode”. Unplug the device from the USB Cable attached to the PC. To put it in recovery mode you must: POWER off the device and the PRESS and HOLD the ‘power’ + ‘volume up’ + ‘home’ buttons all at the same time. Again, I suggest that you start by pressing the “volume” + “home” buttons first instead of pressing the “power” button as you may inadvertently just power the device up (instead of booting it up into “recovery” mode). If you did it right you will boot up in “recovery” mode and you will clearly see the words “CWM-based Recovery” written in white on the top line. If you don’t see that then your installation of the ‘ I9305_CWM_Recovery.tar.md5’ did not work and you will need to repeat the steps above until you get it right.

23)	Next you will be installing the SUSuperuser module while your device is in "recovery mode". Remember you should have stored the “CWM-SuperSU-v0.96.zip” (DO NOT unzip it yourself) on the Device’s internal memory card. Using the volume up/down keys and the “power” button for enter/go you should scroll down and select menu option "install zip from SD card"

select menu option "choose zip from internal SD card"

scroll down to the “CWM-SuperSU-v0.96.zip file and select that using the “power” button. It will then ask you “if you are sure you want to install, it can’t be done”. Scroll down to the “YES” and then select the power button to confirm. It will then mount and install it. Once it is done installing you will then need to scroll to the “go back” choice on the menu. Then go back to the “reboot” device and select that. It will reboot.

24)	Your device should reboot and you should be able to confirm that SUSuperuser is installed by looking at the apps page on your device. You should be able to see a little blue Android with a red cape. If you see it, you have successfully installed.

25)	Once you have root and CWM + SU installed and you want to make a FULL BACKUP of your settings and software. Using the same methods above, boot into “recovery mode”, then choose Backup/restore (select it with the “power button”). Then, it will begin the “back up” process which will take about (7 ) minutes (it takes longer if you are backing up lots of items). Note that the program will back up the backup items onto the EXTERNAL SD Card in a folder named “2012-11-07.10.57.45 (“time stamped”) and it will contain 6 items including boot image, recovery image, nandroid.md5, and 3 others. Mine was about 1.17 gb in size and DID NOT include any music, videos, or pictures. MAKE SURE that your external SD Card has enough free space to store the CWM back up folders. I suggest that you then copy the entire back up folder over to another secure location on your PC (which you can copy over to the SD card anytime) in the event your current external SD card or device goes whacky.

26)	Well, it was not brief but it was detailed and concise and I hope it helps other noobs like myself to successfully install and execute this process as it will lead to further dev opportunities to trying out other ROM’s while being able to reverse the process if things goes really wrong.

27)	If I was of help just say “thanks”. Will try to answer PM if you have them but I am just a noob and may be of little use. This was written by a noob and for other noobs. Hope I haven’t annoyed anyone else in the process.
