Why can't I unroot?

[butterfras]

I rooted with unrevoked tool, applied baseband update, then installed the leaked froyo rom. now I can't make phone calls or anything.

Anyway, I tried to unroot/downgrade using the PB31 file, and when I try to load it, it says that files are newer and won't go on into the process. Any Ideas?

Yes, It said the file was old.

sooo. did you have to dial *228 and reactivate? there really isn't a reason that you shouldn't be able to root and run one of the ROM's available here.

I'm rooted fine and can run custom ROMS, I want to unroot and go back to stock (for various reasons)
