Trouble saving SHSH for 3Gs 4.0.2 in TU

[asdf212]

I have an iPhone 3gs with 3.1.3 and I am trying to upgrade to 4.0.2 - However when I try to request a Blob from Tiny Umbrella, it says I am too late. How can I upgrade to 4.0.1/2 without going to 4.1??

THanks in advance

If you don't have your SHSHs saved, them you are too late, you can't downgrade without SHSHs sorry

Does your phone have new or old bootrom?

If yes and without SHSH files, not possible to go to 4.0.1 or 4.0.2. You can only install 4.1.

If old, JB 3.1.3 with Spirit, install Spirit2pwn = install custom firmware through Cydia, and then, create (pwnagetool) or find (google) custom firmware, and then, restore with that file through iTunes.
