STEP 0: CHECK DEVICE MODEL NO.

To make sure your device is eligible with this, you must first confirm its model no. in ‘About device’ option under Settings. Another way to confirm model no. is by looking for it on the packaging box of your device. It must be GT-I9152!

Please know that this page is meant for Samsung Galaxy Mega 5.8 Duos with model no. GT-I9152 only. Do not use the procedures discussed here on other device of Samsung or any other company. You have been warned!

STEP-BY-STEP GUIDE

Example video: If you haven’t used Odin before to flash a file on your phone before, then we suggest you first watch a video of that to get familiar with the process. The video demonstrates flashing of a Recovery on Galaxy S3, but since the procedure is same, the video will help: Click here to watch the video

Important Note: Backup important files stored on internal SD card of your device, so that in case a situation arises requiring you to do a factory reset after flashing with Odin, which might delete internal sd card too, your files will remain safe on PC.

Extract/Unzip the Odin file, Odin_v3.09.zip on your computer (using 7-zip free software, preferably). You’ll get the following files:
- Odin3 v3.09.exe
- Odin3.ini
Download the kernel file, I9152-JB_4.2.2-boot.tar and place it in the same folder where you extracted the Odin files. You’ll have the following files in the folder now:
- Odin3 v3.09.exe
- Odin3.ini
- I9152-JB_4.2.2-boot.tar
Disconnect the Galaxy Mega 5.8 Duos from PC if it is connected.
Double-click the Odin3 v3.09.exe file to open Odin.
Boot your Samsung Galaxy Mega 5.8 Duos into Download Mode:
- Power off your phone first and wait for 6-7 seconds after display is off.
- Press and hold these 3 buttons together until you see Warning! screen: Volume Down + Power + Home.
- Press Volume Up now to continue to Download Mode.
Connect your Galaxy Mega 5.8 Duos to PC. Odin window will show an Added!! message in bottom left box. Odin’s screen would look like this:

If you don’t get the Added! message, here are some troubleshooting tips:
- Make sure you have installed driver for Galaxy Mega 5.8 Duos as said above.
- If you have already installed driver, then uninstall them and re-install back.
- Connect using a different USB port on your PC.
- Try a different USB cable. The original cable that came with your phone should work best, if not, try any other cable that’s new and of good quality.
- Reboot phone and PC and then try again.
Load the firmware file (extracted in Step 1) into Odin as instructed below:
- Click on the PDA button on Odin and select the I9152-JB_4.2.2-boot.tar file (from step 2). Your Odin window should look like the screenshot below:
Now in the Option section of Odin, make sure that Re-Partition box is unchecked. (Auto Reboot and F. Reset Time boxes remain checked, while all other boxes remain unchecked.)
Double check the above two steps. (Step 7 and Step 8)
Click the Start button to begin flashing, and wait until you see a PASS! message in Odin’s top left box.
When you get PASS! message, your phone will restart automatically. You can then disconnect your phone from PC.

If you see FAIL message instead of the PASS in Odin’s top left box, that’s a problem. Try this now: disconnect your Galaxy Mega 5.8 Duos from PC, close Odin, remove phone’s battery and put it back inside in 3-4 seconds, open Odin and then repeat from Step 3 of this guide again.

Also, If device is Stuck at setup connection or on any other process, then too, try this: disconnect your Galaxy Mega 5.8 Duos from PC, close Odin, remove phone’s battery and put it back inside in 3-4 seconds, open Odin and then repeat from Step 3 of this guide again.
