Samsung phones are notoriously known for the lag issue on their TouchWiz interface. However, one cannot deny the fact that despite the minor and major drawbacks of their phones, Samsung is still the most popular OEM of smartphones. One of the reasons why Samsung Galaxy devices are popular among users is the ease with which we can find the official firmware for our phones and install them using their Odin tool.
If you got a Samsung phone or tablet and are having software-based issues, you can easily restore the stock firmware on it and fix it yourself. Flashing a Samsung device is easier than most Android phones. This is because Samsung provides its own software that can be used to flash all its phone models (Samsung Kies). By using the unofficially released Odin tool, the flashing process becomes easier and smoother as compared to Kies.
The process described below is for flashing any Samsung device back to the original operating system (ROM) and for upgrading to any higher or a lesser version of the Android version.
This tutorial is only for Samsung Android smartphones and tablets. While we have taken utmost care in describing the procedure in a detailed way, the user must be extra careful with selecting the correct firmware file to install it succesfully. If you have any doubts regarding the procedure, we suggest you to drop us a comment below to clear the same.
Flashing the stock firmwares do not void your device’s warranty or trip KNOX Warranty counter. However, if you flash CF-Auto-Root packages or a custom recovery using Odin, doing so will void the warranty. Just follow the tutorial to the word carefully and everything will go fine hopefully. Technastic will not be responsible for any damages caused to your device.
Charge Your Device
Before you proceed to install the firmware on your Samsung device, it’s essential that your device has sufficient battery juice left on it. If the battery turns off during firmware flashing, your phone is hard-bricked. To avoid any unpleasant experience, make sure your device has 60-70% battery power at least.
Enable Developer Options and USB Debugging
To install firmware successfully, you must enable USB Debugging on your phone and tablet. You can find this option under Developer Options. If you don’t find it under Settings, here’s is how you can enable it:
- Open Settings and go to About Device.
- Scroll down to Build number and tap it 7 times.
- You will see a toast message that “Developer mode has been enabled” on your device.
- Now go back to the Settings panel and scroll down to Developer options.
- Tap it and check the box for USB debugging option to enable it.
Install the Latest Samsung USB Drivers
Install the latest Samsung USB drivers on your PC. If you already have them installed on your computer, you can skip this step. If you have Kies on your computer, make sure that the program is closed while you use Odin. You can download the Samsung USB Drivers here.
Backup the Apps and Important Data
It’s very important that you take a backup of all your apps, images, videos, messages, memos, and other important data present on your device before installing new firmware. Usually, new firmware doesn’t wipe any data, but you should still take precautions. You can find hundreds of useful backup apps at the Google Play Store to help you with the job.
