I have an iPhone 3GS that I got with 4.2.1 firmware on it. Trying desperately to find a way to unlock it for overseas use, I used the Redsnow activation method to get it unlocked, but the firmware crashed while it was loading and doesn't seem to be doing anything. I did choose to install the 06.15 baseband as part of this process.
I'm now trying to restore back to stock and start again, but I cannot restore to stock firmwares because of the 06.15 baseband. I also can't get Ultrasnow or PwnageTool working properly to create custom IPSW's to restore to. I still have access as when I turn on the phone it says its in restore mode...I just need something to restore to.
Does anyone have any tips? Maybe a custom IPSW they can send me to help me out? I'd greatly appreciate it!
I don't have the SHSH values either.
