    If you are on a 3GS new bootrom, you can downgrade it to 3.1.3 by following these steps.

    In time, if you don't know whether you are on new bootrom or not, in this same tutorial you'll find a link to check it.

    You can only do it if you have your SHSH blobs saved. Please use Google in case you don't know what it means.

    Don't waste your time, if you don't have 3.1.2 or 3.1.3 shsh blogs, there is no way you can downgrade....

    I dont think you need your SHSH blobs to downgrade to 3.1.x on a 3G, just for 4.0.

    Just shift+restore to 3.1.2 and when you get error 1015 at the end ignore it and use TinyUmbrella or Recboot to kick it out of recovery mode. Then jailbreak as normal with Redsn0w 0.9.3.
