Are you pre-selecting the correct 6.0 ipsw?

What is the exact filename, and how old (approx) is your phone? Is it GSM (uses a sim card)? Also, you want 6.0 (six point zero), not any other version, regardless of what the phone is actually running.

It is a iphone 4 gsm 16 gb. the exact file name looks like the iphone3,1_6.1_10B144 restore.

@shadowowolf READ the above comments. No-one said to select 6.1.3.

Redsn0w has not been updated to recognize anything higher than 6.0. You select 6.0 to trick redsn0w.

@spockers even if i'm on 6.1.2 i should choose 6.0?
