Almost lost my JB
I thought I saved by SHSH blobs and I can see them saved in TinyUmbrella but everytime I went to downgrade from iOS6 down back to 5.1.1 I kept getting an error code 11. I know it is something to do with security software or atleast that what the research I did said. Thankfully I just tried to restore to 5.1.1 and Apple is still signing it. So if you didnt save your blobs and wanna downgrade Id do it ASAP. I did have a back up from iOS6 and iTunes and it wouldnt use that backup but I did select one from the 19th and all is successful I may say. I hope this will help someone with the next day or so. Thought Id share.

Removed BBFW file in the firmware folder of an unzipped IPSW. Can also be used to prevent a baseband update. The device is bootable, if you set the auto-boot to true or use TinyUmbrella and use "Kick Device out of Recovery".
You are trying to update to a custom firmware from PwnageTool 4.1+. You always have to go into DFU mode and restore from there.
