If other jailbreaking tools such as blackra1n, PwnageTool and sn0wbreeze didn’t work for you, you can always give redsn0w a try to see if it solves all your problems.

The process to jailbreak remains same. Open up iTunes. Press Shift and click restore. Browse for the ipsw file you have on your PC. iTunes will restore the iPhone to 3.1.2.

In case you don’t have the bootloaders, download them here and specify their locations in the wizard. Switch off your iPhone and click next. Follow the instructions to enter the DFU mode.

It will now start the jailbreaking process. Do not interrupt the process and wait for it to complete. Once it completes, you would be having a jailbroken and unlocked iPhone 3.1.2 with you!
