Ok first off put your phone into DFU mode, connect it to itunes and hold shift then press restore.

Let it restore, as long as your files are saved on cydia then it will work.

How do i get this file that saved in cydia.

You dont need that file. You just need to follow the instructions, cydia has the files stored, or should have if you have jailbroken the phone before.

All you will need is the ISPW for 3.1.2, which you can find on google, make sure that its for the correct model of iphone.

After i google around i got what you mean. Thanks for the info now my iphone back to 3.1.3.

Boot into safe mode and do it, it will work fine then. I was unable to save it unless I was in safe mode.

download the fw you want to install on your iphone. in itunes click on your iphone and while holding SHIFT click restore and select the fw you downloaded.

Use this instead (#127.0.0.1 gs.apple.com) make sure you type it as it is including the symbol but without the bracket. Hope this help. And also get tinyumbrella to help kicking your phone out of recovery mode.

So the step is easy:
1. get your firmware choice and edit your host file and get tinyumbrella.
2. put your phone in dfu mode.
3. shift click restore and select your file to restore your phone and click restore.
4. After its done it will give you errors but dont worry that is normal dont panic.
5. open tinyumbrella and click 'kick device out of recovery'.
6. job done enjoy
