Click on ‘PDA’ and select file with ‘CODE’ in its name.

Step 9 - Now click on the Start button in ODIN. Installation process will start and would take a few minutes to complete.

Step 10 - After the installation is completed, your phone will restart. After you see the home screen, unplug your phone from the computer.

I am from India. Can I flash this firmware using Odin and then flash my country specific modem? Will that work?
Btw, any idea what is different/upgraded in this official upgrade?

This information is common knowledge & has been covered dozens & dozens of times before in other guides/by other people.

Care to give credit to those sources of people/guides you've ripped the information from, or are you going to be a like a bunch of other people here & plagiarise/claim credit ?

It's fairly obvious you're looking for RC status in doing this (why people would want that, I have no idea; plenty of RC's wouldn't know sh1t from clay), but if you're going to do that at least post something original, and if you can't manage that, credit sources/people you've ripped re-hashed information from.

Edit - Also, this belongs in General, not Q&A. I'm asking mods to move it.
