I have a 3gs that was on 4.1 and 6.15 and tried to update with redsnow to ios 5, but phone did not restore and got stuck in recovery mode. This is the second time happening, how I got out of it last time is I restored to 4.1 and got the 1500 error and used recboot and got it back to normal but that is not working this time and am getting the 1601 error. Please help. I'm on a mac btw.
