  1. When every single one of these pre-requisites is accounted for, you should have a look at the first step we have for you: unzip the upgrade file to the laptop’s desktop.
  2. Once the file inside the package has been extracted, you may do the following: power the handset off, then boot it into Download Mode by pressing and holding Volume Down and Home together while switching the device on.
  3. Then, after you are done with the previous task, you can launch the Odin on the notebook. After you do as such, we recommend you to plug the phone to the laptop and wait; in a bit, you will know if the process is successful. And how will you know that? The Odin shall display a message which reads “Added!!” and a yellow ID:COM box. If neither of the two pops up, you should either flash the USB drivers again or use a different USB port.
  4. Then you can follow these instructions up with others. Such as the following: tap PDA, opt for a file with a CODE name, tap Phone, choose a file that has MODEM as part of the name, tap CSC, opt for a file which contains CSC in the name, tap PIT and go for a file with .pit inside the name.
  5. You have to move on by activating the options labelled F. Reset Time, Repartition and Auto Reboot; the box in the middle should only be checked in case you opted for the .pit file.
