I cloned my ESN but now I don't have service?

[kelz20]

This thread is my last ditch effort to get help because I can't find an answer and I know talking about is kind of taboo. I already changed it and yes, I know its illegal but its my own ESN and its not stolen. Anyway, it appears I did it successfully because when I go to the RTN screen the ESN DEC and HEX are both correct and so are my MDN and MSID but I don't get any bars at all so I'm not able to use voice services at all. I'm thinking I had to have done something wrong even though everything looks correct. When I load the original $SYS.ESN and reboot the phone it gets service again but when I load my modified $SYS.ESN it gets no service and I have looked over the modified $SYS.ESN file in a hex editor and everything looks fine. Its just very frustrating because I've been trying to do this for a couple days now. If it matters, the phones ESN I cloned is a Blackberry 8130 Sprint and I did try updating the PRL which didn't help. Thanks for any help.
