Restore to 3.1.2
Look I've bought a iphone 3gs with the 3.1.2 firmware. I jailbreaked it, and unlocked it, everything seemed fine untill I tried to install Cydia apps.
The phone needed the a reboot, so i rebooted it, and it just turned black. So i tried to start it and the "connect to itunes" logo appeared. So I thought all right, I can just re-jailbreak it. But everytime, I jailbreak it the screen turns black and nothing happens.
So I thought well I can just restore it to factory settings trough itunes. But here's the thing, iTunes tells me to donwload update 3.1.3. And I won't because none jailbreak out there will work.
So is there a way to bypass 3.1.3 and re-install to my factory setting with 3.1.2
-Note I havn't updated it to 3.1.3 yet. So what options have I got?
