was doing a friend's phone. 3G on 3.13. it was never upgraded past 3g. Wanted to put it on 4.1, preserve the baseband and jb with limera1n. Started umbrella, saved the SSH, umbrella confirmed. Downloaded 4.1 ipsw from iclarified. started TSS server. upgraded to 4.1. never got the baseband error. And now the band is on 05.14.02. I am trying to figure out, why did it not preserve the baseband?
