Ok I see you are referring to the original rom. I did try flashing that one once with the 0.41 unlocker. But it froze at 46%, recovered and did it again to 46%. Then I tried Alltel rom and it loaded but had empty values for the radio and prl... and said "Test Only". But it loaded.
I am trying it again with the 2.31 unlocker. Currently at 16%....
-EDIT-
Success! Now I see "Test Only" but the R: 3.37.15
Now I will try the new Almost OEM Sprint rom
Thanks!
