Note : if you use Odin,install official Samsung Firmwares. Custom ROMs,firmwares,and gapps will potentially cause errors and problems while attempting the upgrade.
Samsung users with more than little Android experience would easily understand what is Odin. But for those who don’t know about Odin, this is the best place to know it from starch. To our surprise, most of the users who already used Odin in the past also making mistakes in the flashing process which results in a bricked device.
Tutorial : How To Flash Stock Firmwares On Samsung Galaxy Devices With Odin (Step By Step with images)
Preparation Requirements :
Step 1 : Charge Your Device
Flashing a stock firmware on Samsung Android devices is very easy but it might turn into a nightmarish experience if you are not careful enough with all prerequisites and installation steps. Suppose you are installing a firmware and the battery juice drains away during the procedure, your phone or tablet might be hard-bricked. So make sure that your device is fully, or at least 60% charged!
Step 2 : Enable USB Debugging
This is very important thing to be done before you try flashing a firmware or recovery file. USB Debugging mode make Android devices receptive to download and send data over USB cable connection. If you do not know how to turn debugging mode ON,dp this :1. Go to Settings> About Device.
2. Scroll down to find Build number and tap it 7 times.
3. You will see a toast message that “Developer mode has been enabled” on your device
4. Now go back to Settings panel and you will find a new item called Developer options there.
5. Tap it and go to USB debugging option and check the box to enable it.
Step 3 : Install Samsung USB Drivers On Your PC
Most probably, you might already have Samsung USB drivers or Samsung Kies installed on your computer. But if you have not yet installed any of them, it’s high time to do it now. In case you have installed Samsung Kies, make sure the program is closed while you use Odin or flash the firmware or it might interfere with the procedure.

Step 4 : Backup Your App And Data
Usually, flashing a firmware, rooting and installing a custom recovery leave your phone’s apps, data and settings untouched. However, in some cases it might get wiped. Therefore, we strongly recommend that you backup your apps, contacts, messages, photos, videos and any other important data stored on the internal storage of your phone or tablet. We have gathered together some useful backup apps that can help you backup your device data easily. But,if you feel like you don't need to backup your data,it should be fine. I upgraded my phone with Odin to flash Lollipop firmware,and i don't backup my app and data. The results,nothing is wiped or reseted,only the fact that my phone now is running a lollipop OS is the only thing that's changed.
Step 5 : Download Odin Tool
Now download the recommended Odin tool for flashing firmware on your Samsung device. As you know that there are several Odin versions available but considering the rate of success, you should use Odin3 v3.09 (for JellyBean and KitKat) or Odin3 v3.10.7 (for Lollipop).
