I have a cricket r915. if you have a cricket r915 then the download mode instructions on this site are wrong and will not work. You have to power off the phone or take the battery out, hold down the volume down buttone on the side of your phone, then tap, not hold, just tap the power button, sometimes plugging in the usb cord instead of tapping the power on will also put into download mode with a yellow triangle on the screen, sometimes it gives me a different picture on downloand screen with a different icon. then use the odin instructions, and read them all atleast three times before you start. Good luck
