the best way is to spend some money. I flashed my note 2 fully with a program from a website called cdma flasher . works truth is it cost me fifty dollars, it makes you predeposit funds to flash so each flash costs ten dollars but requires a fifty dollar prefill. when you sign up sign up as a small flash company. i can flash yours is you like for ten plus the cost of you sending it both ways, either way ,its the only legitamte wa ive found to flash from sprint to cricket fully.
