problem with jb on 3gs 3.1.2 7d11
I tried a Blackra1n jb on my 3gs 3.1.2 7d11. BR stuck at "running" while the Itunes tether screen appeared on the phone. Although everything I read said the jb should be quick, I let it sit for 30 mins. but nothing happened. I read through the forum and decided I should just go ahead and restore with Itunes even though I didn't want to upgrade to 3.1.3.
Itunes started the restore then said firmware was corrupted and couldn't continue. I'm not sure if holding down the Home key did it or what but after doing that it went to the apple screen then started up as nothing had happened. I'd like to try a jb again but would like some advice on anything I should do differently. I'm running Vista Home basic if that matters. Thanks!
