US Cellular V3M Orginal firmware file

I have a v3m from US Cellular. I was trying to get a better signal and unlock some of the features on this phone. I flashed it to the alltel monster file successfully but lost phone service. every time I try to make a call it thinks for a min and then says call failed. I got a great signal with this firmware but I need to be able to make phone calls. So I flashed to to the verizon firmware file and ran into the same issue of not being able to make phone calls. Sadly I did not backup the original firmware from USCC. At this point I am looking for some assistance. I either need to find the original uscc firmware file so I can go back to what I had or I need to find some way to get the Alltel firmware to allow phone calls. I would appreciate any assistance anyone has to offer.
