help me please! i'm stuck in 1x mode

[oodayvidoo]

calling all you titan gurus out there. could anyone assist me with this issue i'm having. my phone is stuck in 1x mode and won't go back to EVDO. i dont know how this happened. i was trying to tether my phone and adding wmodem to my phone then somewhere along the way this happened.

i've done a search on here and xda and could not find anything helpful (or maybe i just need someone to interpret this ppc jargon to me in "lay-man's" terms). i tried checking stuff in the epst setting but didn't know where to begin but did read up on the HRD stuff but again, didn't really understand it.

i also tried under phone setting the operation mode and it's on hybrid.

one thing i noticed was that in EPST mode, under the setting column my A-Key (authentication key) was blank. could this be the problem?

someone help me please! i've been at this for hours and am pretty beat
