i wouldn't change the esn for a dmu reset if you have spring esn on verizon, btw dmu key can only be recieved on the phone in verizon area so if your roaming you cant get data back till you hit friendly tower, but more so i'd be worried about getting your esn back on without the system refusing the esn, were you converted or how did you get the esn on original?

dmu reset can be done in the system without changing the esn, call tech and let them trouble shoot your phone, mabey mention you noticed the dmu or a key cleared to steer them in the right direction :P
