If not why you flash it with Claro network? My Phone is SGH-I747M from Puerto Rico.
I'm in Canada and I downgraded to 4.1.1 Claro, thinking I would be able to unlock it. But that didn't work. I'm new to the flashing/ROM etc.
Can you please tell me the steps to get my back to Canadian 4.2.1. I have downloaded lastest firmware for Telus from Sammobile.
Should I just use odin and install the new firmware? Do I need to do something to the ROM before?
Like I said, I'm newbie so all the help would be help.
