This is the step by step guide on how to manually install a firmware update on international variants of Samsung Galaxy S4 with specific model number (GT-I9500) and (GT-i9505) using a stock ROM or firmware. This method is called flashing it through Odin downloader tool. This is only an alternative option on how to update the Samsung Galaxy S4 devices, in-case users can’t update the phone by using the official method through OTA (over the air) and/or Samsung Kies software tool. Flashing a stock firmware is a developers an advance users method, and for those who can’t update anymore due to fact if the phone is already rooted or installed with custom ROM or modified firmwares. So, if you have a Samsung Galaxy S4 that no longer accepts firmware updates, just read ahead below on how you can manually update to the official firmware update that is officially released by Samsung.
Some benefits of flashing stock or original firmware:
1. Unroot your phone and return back to original default settings but you can still root it again.
2. This is also useful on fixing bricked phone, like if device will no longer boot normally or just stuck on Samsung logo.

Before you proceed, grab the necessary files for manual flashing.

– Make sure your phone is fully re-charge to avoid power interruption failure.
– Optional: Back up all important files stored from the phone’s internal memory such as contacts, photos, videos, MMS, SMS, emails, docs etc. Though, most stock firmware is non-wipe but there are some which is wipe versions and it will delete all of your files after the process.
– Optional: perform factory reset to gain a smooth firmware flashing without failures.
– Used Windows based computers or laptops, Odin will not run on Apple products such as Mac.
– Disable any running program on system tray, like Kies, antivirus etc to avoid program conflicts and failures.
– Used the supplied USB cable, flashing failures is mostly caused by bad USB cable. So, make sure you have a perfectly working USB cable wire.

Odin flashing Procedures:
1) Extract or unzip the downloaded firmware, Odin flasher program can’t read it until you’ll get the correct file path which is in (.tar) file format. You can use ‘7zip’ or ‘winrar’ to do that task, I used winrar.
2) Run Odin Downloader v3.07 flasher program.
3) Do Not check the Re-Partition checkbox. Mark check these checkboxes Auto Reboot and F-Reset Time and nothing else.
4) Reboot the phone in download mode: To reboot the Galaxy S4 into download mode , you need to turn the power off. After it completely shut down, 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!!”
5) Connect the phone to PC when it’s in the Download Mode screen. You should notice that the ID:COM box on ODIN will turn to blueish and will show you the port (COM) number.
6) Click on the PDA button then browse to the folder where you extracted the stock firmware.
7) Hit the “START’ button if everything seems all good to start flashing.
8) Wait until a word “PASS’ appears.
9) Remove the phone from the computer once completely reboots.
10) Optional: perform wipe data or factory reset to gain a fresh firmware installation.
Fixing possible failures on Odin:
If you you ain’t get the word ‘PASS!’ and it says ‘completed/failed 1’, all you need is just repeat the procedure above.
If it still fails, check the following again,
– Try to use other USB cable.
– Try to use other computer USB port.
– Try to use other desktop/laptop computer.
