Hey guys I have a friend who has a couple of old Kyocera KX18-W Jet phones. They look pretty solid and thought they would make great first phones for my younger kids. Any idea how to fully flash these to Cricket. I have looked all over and cannot find any info on these devices. Would be great if I could get some help here. I understand you don't even need the MIN/MDN to flash. They can be programmed and then the *228 does the rest but I have not been able to confirm that.
Here is a link to the phone. Please help a brother out!
