Flashing phone back to Sprint... everything works but data?

[cod]

Hi everyone I have an evo 4g with a clean esn that i have activated on sprint. call/mms works as well as 4g. however the phone does not connect at all to 3g or even 1x, and when i turn off 4g it has no internet / data. can anyone help me on fixing this. the esn matches the back of the phone. i have done a few soft resets, used RUU to reset the rom but still no change in the data.

In cdma ws the M.IP matches the meid and my account so i would think that there might be some settings within there or somewhere to get this fixed.

I think i need a backup copy of nv items 465, 466, and 1194 if anyone could give me an original copy from a sprint evo i would appreciate it.


thanks everyone for the help.
