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 Grand 2 LTE into Download Mode

To reboot the Galaxy Grand 2 LTE SM-G7105 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.

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 G7105XXUANB8 4.3  firmware

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 Germany unbranded Galaxy Grand 2 LTE stock ROM on this guide, so it came as I“Kies_Home_G7105XXUANB8_G7105OXXANB3.tar.md5″.

Build numbers varies on each product code, specific geographical region and network CSC  codes.

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

Step 7: Start Flashing the G7105XXUANB8 4.3 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 Grand 2 LTE SM-G7105 in Normal mode.
