Iphone 4s downgrade

problem:

Is there any process to downgrade iphone 4s to 5.1.1 with sshh blobs 
i have my 4s blobs but how to downgrade



solution:

You can downgrade to 5.1.1 for that you should have any ios 4.X.X SHSH and ios 5.1.1 SHSH of respective ip4s , if you have both SHSH simple use latest redsn0w and flash your 4s to it
