general downgrade question

[sverdlov1]

Hello. Can someone answer definitively whether it is still possible to downgrade 3GS iOS4.2.1 if personal SHSH was NOT stored on Cydia previously.

Without SHSHs you cannot downgrade.

I am trying to downgrade to 4.0 from 4.2.1.
- I have downloaded iPhone2,1_4.0_8A293_Restore.ipsw
- I have modified hosts file and verified via ping - i am resolving cydia not apple when pinging gs.apple.com
- I most definitely put iPhone into DFU mode and selecting custom restore via "shift-restore"

iTunes 3194 error every time.

3194 is a failure to downgrade because you don't have SHSHs saved
