I just went ahead and did a clean re-jailbreak on a custom 3.1.3 that I made with sn0wbreeze. I have a 3gs, old bootrom, it was on 3.1.2 with 5.11.07 bb. So, it finished the jb, and connected to itunes, where I said set up as new phone. Then it tried syncing a ringtone to my phone, and said it couldnt because there was no connection with the phone. Now the phone is stuck at the boot logo, with a frozen swirly loading bar. I thought maybe it was a bad jb, so I re jb again.... same thing. Any thoughts? I dont know what I did wrong.
