What is a Stock ROM?

Stock ROMs are the firmware that has been released from Samsung Kies official firmwareserver. These are being pulled from Kies by an Android firmware experts and carefully re-bundled it to make it flashable by using Odin flasher tool, via CWM and some prepared tool like chainfires’ Mobile Odin. This guide here tackles a Odin flashable stock ROM only, you might also see other methods like flashing via CWM and Mobile Odin (whuch is to be added soon).

Stock ROMs contains the binary and image files of the whole software packaged, like these:
* Sbl.bin
* cache.img
* factoryfs.img
* hidden.img
* modem.bin
* param.lfs
* zImage

Inside the stock ROM bundled, those binary and images files are packed in three different formats.
Some full packaged stock ROM comes in multiple package this includes with BOOTLOADER image and PIT files, but in flashing it’s been safe not to use these files.
PDA – This the software/firmware build number version and consists to a code of numbers and letters
CSC – (Consumer Software Customization) Refers to the specific country or carriers for that said firmware is being build.
This where it contains the default settings of each specific geographical region, carrier network providers and network data connections.

Phone – This renders the specific Baseband or device modem data (GSM/HSPDA).

PIT – the PIT file refers as ‘Partition Information Table’. This is only useful for fixing bricked devices if somehow something changed with the partition table layout of the phone’s system memory. But in normal flashing, you should not use this file, or you may screw up your phone if handed carelessly.

Step 2: Extract the downloaded stock ROM

You need to extract the downloaded file which is packed in zip or rar files, so that you’ll get the tar.md5 file.

Step 3: Run and Configure Odin

Run Odin downloader Odin3_v3.04 on your PC desktop. Watch out the check-boxes options on the right top of Odin, ensure that the ‘RE-PARTITION’ is unchecked, only  the ‘AUTO-REBOOT and ‘F.RESET TIME’ checkboxes are both remained checked.

Step 6: Reboot your Galaxy S3 into Download Mode

To reboot the Galaxy S3 into  download mode , you need to turn the power off.  After it completely shut off,  just  press and hold the Volume Down key,  Home button and the PowerON/OFF button simultaneously.

You should then prompted into a warning screen and asking you  to press volume up if you want to continue or volume down to cancel, just simply press volume up to get into download mode. The download mode then displays an Android robot and say’s “Downloading.. Do not turn off target!!”

Step 5: Connect your Phone to PC or Laptop

Once you already reboot the phone in download mode,  simply connect the phone to your PC or laptop USB.
In Odin window – the ID:COM box will turn to blue color and indicates the COM port number and a word “Added” on a log box will prompt you that the device is already detected or recognized by Odin.

Your COM port number might be different from mine. If you do not see a COM port number then there’s something missing or wrong. You may read again from the top of this post.

Step 6: Load the binary .tar.md5 file

If the stock ROM is pack in One .tar.md5 file only the PDA, CSC and Phone modem are already included to it. Now, you need to just simply click on the PDA or AP button, then browse to the folder where the .tar or .tar.md5 you have previously extracted and then select and load it.
Just like this image below, I used Switzerland unbranded Galaxy S3 stock ROM on this guide, so it came as I“I9300XXUGNA5_I9300AUTGNA1_I9300XXUGMK6_HOME.tar.md5″.

Build numbers varies on each product code, specific geographical region and network CSC (Consumer Software Customization) codes.

Note: Again, DO NOT load or put a ‘PIT’ file.

Step 7: Start Flashing or Installing the stock ROM

Once if all set and ready to fire-up, hit the “START” button in Odin to begin flashing the stock ROM.
Do not ever interrupt the phone while already in flashing progress, like disconnecting the cable or turning off the device. Just wait until it completely finish.

Step 8: Watch out for the word PASS!!

When the Stock ROM installation successfully completes, you will then see a word “PASS” in Odin. This indicates that the flashing was already finish, and on the log box it says “All threads completed. (succeed 1 / failed 0)”. The phone will just then automatically reboot, then it’s to remove it from PC or laptop USB connection.

Confirm your fresh firmware installed by typing *#1234# or
Go to Settings>About Phone>Firmware info.
You can also do factory reset by dialing *2767*3855#.
Check and reconfigure your APN settings when data networks connection issues encountered. This only happens if you installed other regions stock ROM.

Possible errors that you may encountered, this is based on my own experience while flashing stock ROM on Samsung Android devices. These are just a few hints on how to resolved it.

Q: I got an error message that says “Set-up connection Failed” ?
A: 1. Check your USB connection from the phone to PC,
2. Connect to another PC USB port
3. Check and try to another USB cable
4. Re-install the USB driver.

Q: Odin just suddenly stuck in the middle of nowhere while in flashing progress, It isn’t responding at all?
A: Check for possible program that might interrupt the process, like disabling the anti-virus and closing any running programs.
Try to use another PC or laptop,

Q: I experienced bootloop or the phone just stuck on Welcome Logo (phone always stop at bootanimation) and it won’t boot normally?
A: You can fix it via recovery mode option, do this:
Boot in recovery mode
1. Press and hold Volume Up, Home and Power button.
2. Use volume keys to select, Up and Down and Power or Home key to select the option
3. Select Wipe Data/Factory Reset using the Home button.
4. Next select the Wipe Cache Partition
5. Lastly, select Reboot System Now to reboot your Galaxy S3 in Normal mode.

Q: My Galaxy S III is now soft-bricked, what should I do then.
A: For 3 years, never been happened to me soft-bricking my older phones using Odin, I was once got soft-bricks using ROM manager. But if somehow this happens to your device, here’s how.

If you can still access the phone in Download Mode, then you can recover it by repeating the flashing procedure again.
If not, that’s seriously bad. The only option is to send it to your nearest service center. Folks at service will recover it by forcing to re-flash the firmware via JTAG.

That’s it! you have now learned how to install Samsung Galaxy S3 stock ROM. You can use this procedure again and again, using any future stock ROM that only match with your device. But remember DO NOT use this method to downgrade your Galaxy S3 to any old firmware since the latest 4.3 updates has a new security policy guidelines which prevents you to downgrade. All other questions and suggestions are most welcome, just let me know by leaving a message on the comment form below. Enjoy!.
