The Firmware is the microprograms (software and operating system) that are incorporated in the device’s ROM or Flash Memory to control how your device works. While the non-rewritable firmware cannot be altered, there is some firmware that can be updated or replaced in a process called firmware flashing. Thus, you must know How to Use ODIN.
For such purposes, there is the requirement of specific firmware flashing tools. ODIN is one such windows tool that allows firmware installation in Samsung Android phones. This software was initially developed by Samsung and has been used internally for updating, restoring and unbricking Samsung Android phones. Presently this software is available online as a third-party application and has been supported by the Android community for flashing, modifying and unlocking phones.
Flashing your android phone is a relatively risk-free task. But Odin is a powerful tool and should be used with prior knowledge of how to use Odin, and it should be used at your own risk. For the convenience of new users, here we have put together this In-Depth Guide on How to Use to Odin.
How to Use Odin
To begin with, here are some precautionary steps that need to be taken to ensure safety:
- Download and install phone USB drivers on the PC to be used. Majority of the phones will directly install their drivers once connected to the PC. If that is not the case, you can refer to this link for the list of compatible USB drivers for your Samsung phone-
- Create back-up for the entire phone data and settings like APN Settings, SMS settings, etc.
- Enablable USB debugging on the Android device.
- The phone should have ample charge before starting the flashing process. Preferably maintain 80% or above charge levels.
- Often Samsung Kies is incompatible with Odin. Hence if you have Samsung Kies, then you need to make sure it is not running, or best uninstall it before beginning the process with Odin.
Steps on How to Use Odin
The first step of the process should be downloading the latest version of Odin software available. You can try this link. Otherwise, a Google Search can also give several download links for the newest version.
Although, using the latest version of Odin is always advisable, but some old phones may not be compatible with the most recent versions. You can refer to this link to check your phones Odin compatibility.
Once downloaded, you will have to extract and run the Odin.exe file as Administrator on your PC.

Download Mode On
There is a separate Download Mode or Recovery Mode for every Android device. To boot your Samsung Android device in this mode, first power off your phone.
Now, while booting your phone, hold down the Power, Volume Down, and Home button in unison till the Android Warning sign appears. Press the Volume Up button again to proceed into the Download Mode.
With the Odin application running on your PC and your phone in the Download Mode, connect the two using the USB cable. Ideally, Odin will detect your phone straightaway and the ID: COM port in the Odin application will change to yellow and show your phones port number.
If these changes do not occur, that means that the PC did not detect the phone either due to incorrect USB drivers or because Odin is not being run with administrative privileges.
Add firmware to Odin
Odin requires the firmware download before to flash your phone. For this go to the PA or PDA (depending on the version of Odin) section and browse and upload the firmware file to Odin. The firmware download will have only one tar.md5 format file which you have to upload.
If the downloaded Odin package contains multiple files, then the process becomes a bit lengthy. You have to go to PDA section and upload the PDA file (having PDA in its name), go to CSC section and upload the CSC file (having CSC in its name) and click on the PHONE section and upload the file that has Modem in its name.
Once the file (or files) is selected Odin will take a few moments to analyze it and ready itself.
Once you reach this point, you will find several checkboxes. Only select 2 checkboxes- the Auto Reboot and F. Reset time. Rest of the boxes should remain unselected. This selecting enables critical options of successful flashing of your device and is a step that people may often forget. BUT, do not forget!
Let the Flashing Begin
Hit the ‘Start’ to let Odin start the process of adding your selected firmware to your phone. While the process is ongoing, strictly do not touch your phone or USB cable as it increases the chances of your losing connectivity with the PC and compromising the whole process.
Finish and Reboot
This is the last step on this How to Use Odin guide. It takes about 5 minutes to install the firmware on your device ROM. The device will automatically reboot several times, once the flashing is complete.
After successful completion of the process, the Odin will display a green ‘PASS’ message, indicating that the flashing is complete. Until this message appears, it is advisable that you don’t disconnect your phone from the PC.
If you have followed this how to use Odin guide to the letter, then you will not run into any ‘Error’ messages on your journey to successfully flashing your phone.
