Kyocera driver and other flash questions

[thenab0303]

Idk how active this place is anymore but I have to give it a shot. Alright here's what I'm attempting, I have a Sprint Samsung Galaxy S3 that I'm trying to flash to Boost Mobile however I am having problems. First off the other phone is a Kyocera Hydro which I can't get to communicate with CDMA Workshop or DFS. I have the MSL code and have put the phone into Diag and have a COM port called KYOCERA USB KC02US Serial Port (COM10), but I keep getting Failed...Phone didn't answer. Another problem I have gotten is after flashing my personal Boost Mobile phone's ESN to the S3 and turn it on I get 3G data and calling however no SMS, how would I go about fixing this? Another question, what does the AAA password do exactly. That's all I can think of atm, hope someone can help me out.

*EDIT* Seeing the S3 worked other than texting on an already active account would flashing the other phones ESN to the S3 and then activating it on it's own Boost account be alright? Would it fix the texting issue?
