Help: Jailbreaking 3.1.2 IPSW with 06.15.00 Baseband
My iPhone's Details
Current Firmware: iPhone1,2_3.1.2_7D11_Restore.ipsw
Current Modem Firmware (Baseband): 06.15.00
I'm stuck, I want to jailbreak my iPhone but Redsn0w 0.9.6rc8 does not recognise the IPSW. I'd prefer it if I could use Redsn0w 0.9.6rc8 because of the new features (tickboxes) including 'deactivate'. I've tried downloading Redsn0w 0.9.2 but the program crashes into debug mode. Please can someone advise me on what I need to do. Bear in mind I'm using modem firmware 06.15.00.
On a sidenote - I want to unlock my iPhone to a different network. When I previously tried this I managed to jailbreak and unlock the iPhone using Redsn0w (on 4.2.1 - I dont want 4.2.1 this time, it makes my iPhone 3G very slow) and Ultrasn0w but then had 'no service' no matter if 'enable 3G' was on or off. Does anyone have a solution to enabling carrier signals to work correctly?
Thank you for your time and help! :)
