Been researching flashing a leak, have some questions. 1) when you download the necessary file do you do it on your phone or do you have to do it on a pc? If A PC IS REQUIRED DISREGUARD THE REST AS I CURRENTLY HAVE JO ACCESS TO ONE. 2) if you can do it on your phone will the file automatically go to the root of my sd card? If not how do I get it there? And will I need to rename it? 3) if I make to that point volume down and power button to start the process? Sorry ....I'm not very tech savy....lol Thanks for any help!!!
