Original state of 3gs: Version 3.xxxx Basebands 04.26.08 Bootroom 6.4 I used Snowbreeze It recognized the file that I downloaded 4.3.1ipsw The JB went thru smoothly without any kind of error. At the end, I can't click exit recovery in the TinyUmbrella, So I click Fix Recovery then the log says to allow the device to reboot. I turn it off. Now it won't start. What have I done wrong? Can I still fix this? Please advise.
