There is no point going to 4.0.2, it won't let you just shift + restore unless you point your hosts file towards Cydia server for verification. You haven't mentioned your device yet, so can't give you anymore info.
You can either use Tu tss server to do the restore but you have to store your shsh blogs onto it first.
Run Tiny Umbrella
Plug in your iphone.
Highlight your device on the left side
Click save shsh.
Put your iphone into recovery mode.
Now highlight the shsh blogs in TU,
Start tss server
Do the shift+ restore to 4.0.1 or 4.0.2 ipsw on your computer
