Tp turns on then off after cab radio install

[chasedinero]

Ok this is what happend my battery kept draining and i never have good any bars. So i decided to upgrade my radio, bad idea. I had to leave home to use the internet else i wld tell you where i got the files from. Anyway, they we're cab type files and i loaded one thru activesync, didnt really think it worked cause it kept saying home service (but phone was still working). So here we go I load one of the other radio cab files that i downloaded from this same site without removing the other cause i didnt think i had to. The cab loaded with success it said reset. Now my poor tp turns on load gets to today screen and just shuts down.
