Normally, you should find an .ipsw on your desktop.

Rename it to .zip (change .ipsw to .zip) and unzip the archive. Inside, you should find a file called “kernelcache.release.n88”. Replace it with the one previously downloaded in the archive.

Close the zip, and compress the file. Then change the extension .zip to .ipsw.

Normally, you should be able to restore with this firmware and have an iPhone jailbreaker in 4.0.2.

Of course, no one from the iPh team is held responsible, and we have not tested this version of PwnageTool: it is at your own risk!

Info. If at the launch of Cydia there is no source and the icon is white, add this source: http://apt.saurik.com/cydia-3.7

then refresh the data 😉

Info 2. We advise you to stay in 4.0 / 4.0.1 until the dev-team finds a solution!
