my sprint tp2 wont connect to data after flash

[mm1453]

so just last week i decided to try out some different roms and start flashing. flashed my first rom successfully everything was a ok, but then i decided i really didnt like the rom i flashed so i flashed a new one on but i accidentally flashed a gsm rom onto it and it didnt boot. so i then flashed mighty rom on via sd card. I set up my provision carrier and everything seemed ok except my phone would not connect to sprints data. I erased the memory a couple times set everything up and still nothing. Im getting some kind of pcs error message. I then flashed the original sprint rom back onto my phone and still nothing. hopefully someone can help me out. if not my next step is to lock it back up and bring it to sprint.
