When exactly are you getting that error message?

You will need to download the windows version or mac version of ibricker. (Please note you will need to download versions 0.8 and 0.9) in order for you to downgrade correctly from 1.1.2.to 1.0.2.

Error 1015 is also fine. Just get the java jailbreak 1.1.2 package from conceited software and run windows.bat from it and click "boot phone" button. Then continue on with the jailbreakme.com.
