Samsung has been rolling out the official Android 4.1.1 Jelly Bean update for the Galaxy S3 since the last month. The new firmware has already hit Korea, Poland, selected European countries, India and a few U.S. carriers. The company is planning to treat all Galaxy S3′s with the JB update by the end of November. Here, in this short tutorial, I shall be showing you how you can install the official Jelly Bean firmware on yourSamsung Galaxy S3 on the stock ICS firmware or on some custom ROM. It is not a new method if you have been flashing stock firmwares on any Galaxy handset using Odin.
Preparations to be Made before you Proceed:
Here are a few pre-requisites to be taken care of before flashing a stock firmware on to you Galaxy S3.
- Download the correct version of the firmware for your country/region from one of these sites and download if available: Droidviews, Samsung-Updates, Android Firmwares.
- If the downloaded firmware is a zip file, extract it to get the tar file with the same name.
- In my case, I have downloaded the I9300XXDLK1_I9300ODDDLI7_INU.Zip (for India).SAMSUNG UPDATES
- Download Odin3-V3.04.Zip and extract the zip on your desktop.
- Download Samsung USB Driver and install on your computer
- Open device Settings and turn on USB Debugging on your phone: Settings> Developer Options> USB Debugging.
- Do not forget to charge your device’s battery to a decent level (above 60%).
- Backup your contacts, messages, and all other important things to some external storage using some good backup app.
- If you want to upgrade to the new JB official firmware from the stock ICS, just leave this step. But if you are going to flash the stock update over a custom ROM, it will be good thing to “wipe data/factory reset” and “wipe cache partition” to avoid a possible Bootloop after flashing the new firmware. This is how you can do it: boot your device into CWM Recovery mode. Turn off your device; press and hold the Volume Up and Home (center) buttons together and then press the Power button for some 5-6 seconds. You will see a black screen with blue texts. Here you will find the options towipe data/factory reset and cache partition. Having performed the two wipes at the Recovery, reboot the device using the reboot option in the recovery. Here your device might stick at the bootscreen. Do not panic and pull of the device’s battery. Wait for a few seconds and reinsert the battery to its place and move on to Step 1 in the instructions section below.
Flash the Stock JB Firmware to Galaxy S3:
Okay, now you are just a few clicks away from the pleasure of having the Jelly Bean ROM on your Galaxy S3. Follow theinstructions given below carefully.
- Boot your device into download mode using the same method as described above. The only difference being that this time you have to replace the Volume Up key with the Volume Down button: Volume Down+Home+Power keys. The next screen will prompt you to press the Volume Up key to proceed to the Download mode (see below).
- Now double click on the Odin3 v3.04.exe file to run the Odin3 flasher program.
- Connect you Galaxy S3 to your computer via USB cable.
- You should see the ID:COM port at Odin3 turn green with “0:[COM7]” text and “Added” text at the Message box below. This shows that your phone has been detected by Odin3.
- Make sure that only the “Auto Reboot” and “F. Reset Time” options are checked on the Odin.
- Now click on the PDA button and select the firmware file with .tar.md5 extension. The firmware file name should look similar to this: I9300XXDLJ5_I9300ODDDLI7_INU.tar.md5 (the version and region codes might be different for your country).
- It’s action time now. Click on the Start button and and let Odin do its job. The installation will begin and will not take much time.
- When it is finished, you would see “PASS!” message on ID:COM port with green background.
- Your phone should reboot automatically. Disconnect your device from the computer.
