New bootrom, never was supported by blackra1n RC1, that came in RC2

Your only option is to restore stock apple IPSW. I hope you have a SHSH backed up for 3.1.2 otherwise you can only restore 3.1.3

This answers your question. Everything you asked has been asked before, you double posted and did not bother to search for existing solutions. Thread closed.
