sn0w Post Install Log... :mad:

[j0sh866]

So I've done plenty of unlocks with blackra1n/sn0w but can't get passed the sn0w post install log no matter what I do. I usually just try it again, and it works. I have tried it 100 times, installed sn0w separately from Cydia, turned off 3G, pretty much have done everything people have said to do online, but still can't get past the post install log. What can I do? I believe the phone has 3.1 firmware.
