Sprint TP flashed to metro, phone stopped working when flashed to stock rom

[ChonDee]

Hi,

I got my sprint touch pro flashed to metro pcs, then I flashed it to mighty rom 6, and it was working all good for a long while. After I saw all these new roms coming out, with newer manila I decided to flash a new rom, and I read that it is better if I flash the stock rom before flashing to a custom rom, and so I did. After I flashed to the stock shipped sprint rom the phone stopped working, and after I flashed the custom rom, nfsfans B14 rom, the phone still doesn't work (I can't call or receive calls). I have installed the carrier cab for metro pcs, but it doesn't work, and anyways, as far as I know it only takes care of the internet, right?

Did I break the phone, or can I do something in service mode? Do I need to get it flashed again?

Please, any help would be greatly appreciated.
Thank You!
