Stuck on Error 67?
 

I recently had an issue upgrading to nue's 5049 rom, it appeared to degrade the radio firmware. it wasn't the rom because i'm currently running it, but i could not connect to EVDO w/ sprint. no matter what I tried I was getting the error 67. Everything was configured correctly, just ask the sprint rep I spoke with for an hour.

Eventually, to fix this problem I ran the relocker and installed the offical Sprint rom. I was able to at this point go back to 3.16 following these instructions. Just thought I'd let you know in case you were going crazy.
