Banner update -- QPST write error

[RookWV]

A long while ago I flashed to a Sprint ROM and didn't catch the customization in time so I ended up with a Sprint branded phone.

Finally got around to messing with the phone again and when I use QPST to change the banner back to my carrier I get an error message when I try to write to the phone.

It says something like NV_PPP_Password and NV_Status_S (sorry I don't have the phone with me at the moment.)
Anyone have any ideas?

I looked at the PPP settings and for the username it has all zero's for my MIN but the correct MIN information is present. I get a similar error (NV_PPP_Username) when I try updating it.
