Can someone please help direct me to a custom firmware that will work with my phone? I have tried a few versions I found on the web but I keep getting the message in itunes that the firmware is incompatible with my phone.
I have a 3gs with the newer bootrom, 6.15.0 baseband, and a valid at&t sim card.
Thanks. I went through some of the videos on youtube and created a custom firmware but I didn't see where to specify 2 things, maybe you can help?
In Pwnagetool (I'm using 4.3.2 PwnageTool to create a custom 4.3.2 IPSW) or elsewhere where can I tell it:
1. That I have the newer firmware for the 3GS
2. That I have the 6.15.0 baseband
^The videos are not always current. Run PwnageTool in Expert Mode, and select the options as appropriate (especially [H]Activate yes/no) and build. If it doesn't ask something it's because the answer is not needed.
