Can't get Gingerbread to boot.

[i.am.root]

I followed all the steps. Factory wipe, sbf 340, root, Droid 2 recovery, but when I try to load the first Blur_Version.23588.p1.zip I get error code 7.

I also tried flashing 595 deodexed but I get boot loops. I have to sbf back to 340 just to get the my phone to boot again.

Is there something I'm missing?

Right now I'm running Liberty 2.0.1, which is fine, but I want to be able to use Netflix. It's the whole reason I'm trying to run Gingerbread.
