I did a meid repair on my HTC evo 4g. Afterward I did an OTA activation and everything seemed to be working fine. I can call, text, and 3g however when I attempted to turn on 4g I got an error code 67. So obviously I attempted to update my PRL and again error code 67, then I tried to update my profile and again I got error code 67.

The phone seems to be working fine except for I can't update my PRL or use 4g.
I'm still on the sprint network, so how can I update my PRL?
Does 4g use some sort of separate identifier that I might need to manually set?
