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 4: 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 Power ON/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.

Step 6: Load the binary .tar.md5 file
Now, you need to just simply click on the PDA 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 the I747UCALG1 stock ROM on this guide, so it came as I747UCALG1_I747ATTALG1_I747UCALG1_HOME.tar.md5.


Note: Do not 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

will this work if im on android version 4.1.1 or how to downgrade im using am shg -747
baseband I747UCDLK3
build JRO03L.I747UCDLK3

please let me know

yes it works no matter what version of software you have. why you using 4.1.1. I use the liquid smooth 2.4 with BWM 3.4. works great even clocked at 1.83 Ghz

it was stock firmware its not rooted

yes it is stock rom unrooted. that's what stock rom is. I have not ever seen a custom rom unrooted.

flashing now 537 pm hopefully it will work

phone is stuck on the samsung screen ,it did not work
i did everything as the post said

still not booting up

please help

did it flash correct with ou8t any issue? Do you still have CWM installed on it? You may have updated the boot loader past LK3 which makes problems getting it back before LK3. Why you trying to get back to stock anyway.

Normally you get stuck at the black screen is because of kernel and bootlader can keep it from loading up. Are you trying to speed it up? I been using liquid smooth 4.2.2 for a while now and it works great. I will do some research to see what we can do to help

well tried it but still no go sucks,couldnt go back to ice cream but was able to go back to jelly bean

Just curious, is there some function your looking for that was on the stock ICS that you don't have in JB? If it is apps that is no longer used, you can get those back. If it is flash, you can install flash 11. I use flash and it works great on 4.2.2.

i love the calendar in one of the ice cream builds

you should be able to get that in newer build. you may have to save that apk and install on newer rom
