I've searched but can't find my exact situation.

I have an iPhone that came with 1.0.2. I revirginized it, updated to 1.1.1, did the prep thing updated to 1.1.2, unlocked with anysim 1.1.2u. Then i tried to run the official 1.1.3 updater from installer. It seems to go thru the process then just stops at some point, and goes to restore mode. I can't get it to do anything from there.

I've restored to 1.1.1 and am going to go back up to 1.1.2 and unlock. Any ideas on why the upgrade to 1.1.3 isnt working?
