Step 2: Go to Extras > Custom IPSW.

Step 3: Choose the original IPSW file on the iOS device downloaded from the link above.

Step 4: Now the custom IPSW file will be created by redsn0w, the one that has preserved the baseband meaning one will still be on the previous version (baseband).

Step 5: Go to Extras > Pwned DFU to enter Pwned DFU mode. Follow the on-screen instructions.

Step 6: Once there, go to iTunes and press Shift+Restore (Windows) or Option+Restore (Mac).You need to choose the correct IPSW file. It will have a prefix "No_BB".

Now you'll have a custom IPSW on iOS 5.1.1 with a preserved baseband.
